Lost Playhead in QT with Streaming Media

We have 3 different computers in our house, Mac Pro, Mac Mini and PowerPC laptops. We used to stream media (radio, TV) from a series of websites, using Flip4Mac to convert Windows Media to compatible steams for QuickTime Pro. We would then save portions of the streamed media using the Select All function, cutting and pasting, etc. I could export shows from the streamed broadcasts to my iPod, etc. No longer. The playhead and selection bars have disappeared and the 'copy' and 'paste' are gone from the menus. When the streaming media come up, the phrase, "buffering..." briefly appears and then the bar next to the time in the browser becomes gray. The streaming begins without the playhead. Oh, yes, all the software is up to date. ....
However, if i re-load an older movie or download a video, i can still get these items. I went to see one of the geniuses at our local Apple Store, and after confirming that the functionality existed for the same streams in the store itself (also running Flip4Mac), explained the problem. Hours later, after everyone in the store had messed with my computer, i left with no solution, except to re-install Leopard. Of course, i wasn't going to do this without re-installing my preferences, files, etc., and after all this, still no playhead!
Someone out there has solved this problem. I know this because i read the solution a couple years ago here and resolved the issue. If anyone out there has solved this problem, please help! (Perhaps some Apple Developer is curious to know what kinds of bugs are out there and can set us straight?)

So sorry. Sounds as if you have the same problem i had.
However, in addition to proving to myself that QT can be made to work by going to the Apple Store, as recounted earlier, i have now established the same thing at home, where i really needed it. It was brute force but successful. One of our older Power PC G4 laptops had the problem i have described, but the other did not appear to have it. The playhead was still there, but in the player, not in Pro. (We had never upgraded to Pro on this computer.) Tonight, i upgraded this computer to Pro and not only the playhead was there, but also the copy and paste functions. After installing a trial version of Flip4Mac, i verified that the playhead and other functions were preserved. I then went through the laborious process of compressing virtually every file related to audio components, QT files, and WMV files on the first computer. Finally, i trashed everything and transferred the components from the second computer. Et voila, after restarting, there was the playhead and other functions on my first computer again ---- and i am now able once again to save clips from the so-called 'pure stream' of the URL given eaerlier in this thread. So, indeed, there is some kind of configuration bug that is very difficult to eliminate except by an extreme measure like this. (Re-installing Flip4Mac and QuickTime didn't resolve the problem.
Good Luck with your own computer ---- but then perhaps you don't care whether you can save clips from a 'pure stream' ..... I really wish Apple would document this and resolve it, so people don't think it's something natural and inevitable. And that they would come up with a simpler solution!

  • Streaming remotely with streaming media player

    I have a Sony SMP-N200 Streaming Media Player and was wondering if it is in any way possible to connect it to a remote network/server. I thought it might be a good Christmas gift for someone to get them a media streamer and give them access to my extensive movie library, or simply have the ability to bring it with me when I leave town and conenct to home. I understand that most of these things only connect to home networks, but if it's so easy for PC's and smartphone to play my media anywhere, maybe there's a server software or app to download to the SMP-N200 which will allow this.

    Hi hizzoze,
    SMPN200 Network Media Player cannot be setup as DLNA server. It is a DLNA renderer device. Information about DLNA device classes is mentioned on the below page:

  • Server 2012 SMB 3.0 file cluster issues with Streaming media services 2008 R2

    So I have a file server setup with the always available feature turned off on this brand new cluster. Everything seems to function normally and I can hit files from the shares no problem.
    My issue I built a brand new 2008 R2 machine and created an on-demand publishing point to point to my 2012 file share cluster. I created a windows account for my windows media service to run as and applied read only to my video share. Media services see
    the video files on the server in the GUI so I know its got connectivity, but when I go to test locally or externally it will not play the stream at all. It complains of access even know I know that is not the issue. I have verified the setup and the ACL
    stuff is turned off on both the root and the publishing point. I can login to the Media server as my service account and play files from the share no problem. IIS media services can stream the files with no problem and yeah everything seems more like something
    possibly with SMB 3.0 and something in media services.
    I have a country rule where my data is not allowed in other countries so I have multiple video services on a domain with tunnels and what not my US Streaming services is working great but has a server 2008 R2 file cluster server. If I take that one to my
    out of the country publishing point to test it streams great as they use the same services account. If I take my out of the country file share to the US I get the same result just will not work. I have poke prodded and banged my head and since I get this result
    I have concluded it must be something with the new security of SMB 3.0.
    Does anyone have this working or tested? Also I am using the exact same video file to test all of this. Or is there secret I missed to either make smb 3.0 even more compatible or make streaming services play nice.
    Anything helps please let me know.
    Thanks,
    Adam

    I'd recommend calling in for support on this one.  Things aren't adding up.  Probably the most useful thing to do would be to do a network trace of the WMS server connecting to the remote server over SMB.

  • Premiere Elements cause problems with Windows Media Center while streaming to TV.

    I was having the following problem:
    The audio from the streaming process of a recorded TV show on my HP computer to the remote receivers, a Sony Blu-ray player and/or a Sony Streaming Player, results in the loss of audio signal at exactly 30 seconds from the beginning on either devices. The video continues on as normal.
    A user on the Windows 7 forum had the following possible cause and solution.  His response was as follows:
    I "solved" my issue, at least partially. Turns out for me a codec installed by Adobe Premiere Elements for audio (Main Concept) was causing mfpmp.exe to fail (you should see it getting an appcrash in the event log two or three times as soon as you start playing the media remotely.) This program is used by microsoft for DRM. I went through and one by one remained the various attached (non-microsoft) modules until i found the one that caused the appcrash. I haven't fully figured out if Elements is now negatively effected, but that's for a different forum.
    I tried the quick fix by un-installing Adobe Premiere Elements.  The uninstall solved my problem with Windows Media Center, but I want to re-install the software but I do not want to recreate the problem with Windows Media Center.
    Is there another solution for this problem?

    I reinstalled Adobe Premiere Elements 10 and the above mention problem reoccured.  With a little detective work I was able to determine that the file causing my problem was "mc_dec_dd_ds.ax".  I am not sure what this does to Adobe Premiere Elements 10 since I removed (renamed) the offending file.  A strange side affect, renaming the file did cause an increase volume. Strange.  

  • Record rtsp streams with azure media services

    Hello.
     I see that Azure media service now has rtsp streaming support, but, as I understand, it can stream videos from azure, but what about recording of incoming rtsp streams? Is it possible to record rtsp streams with Azure media Service?
    Andrey

    Quick correction for you... We support RTMP.  Not RTSP.
    You can send a live RTMP stream to us and we will record it.  You just need to enable a live Channel and start a Program on it.  It will archive the live stream to storage so that you can play it back as VOD.

  • Live Video streaming with Adobe Media Server

    Problem:
    I have 10mbit up/down internet connection. I will do video streaming a live meeting to around 350-400 live watchers
    So i can't use regular streaming to all watchers. Then each user will have 3kb/sec rate which is a terrible speed.
    Solution:
    here what I understand about Multicasting.
    I have a dedicated server with 1gbit dedicated port.
    I will only stream my video to dedicated server and the watchers will be getting data directly from dedicated server which have 1gbit port.
    Can I do this with adobe media server?

  • How to test streaming bandwidth on localhost with Flash Media Server ?

    Hello,
    I'm trying to debbug my code on Client side (Action Script 3) that works with Flash Media Server 4 on localhost. Everything seems fine up to that point.
    However, when I'm trying to test my player with other remote streaming servers, I notice bugs because of lower bandwith transmission between the server and the player.
    Is there a simple way to simulate lower bandwith with FMS4 on localhost (by config, application.xml, programmation...) ?
    Thanks
    Seb Ethier

    Thank you zarihs Rawna
    Indeed, i have been with Server-Side ActionScript (SSAS) way. it's more simple, i think.
    Well, here the step what i did :
    Step 1 :
    Make a file "main.asc" et copy & paste the code below.
    - more info : http://www.peachpit.com/articles/article.aspx?p=31217
          *main.asc*
        var bandwidth;
        application.allowDebug = true;
        // Application callback functions
        application.onConnect = function(client, user) {
            //12800 = 100 Kbps   
            //64000 = 500 Kbps
            //131072 = 1Mbps
            //327680 = 2.5 Mbps
            //983040 = 7.5 Mbps
            //1966080 = 15 Mbps
            //3932160 = 30 Mbps
            //6553600 = 50 Mbps
            //15728640 = 120 Mbps
            bandwidth = 64000;
            client.setBandwidthLimit(bandwidth, bandwidth);
            trace("clientToServer = " + client.getBandwidthLimit(0) +  " serverToClient="+  client.getBandwidthLimit(1));
            application.acceptConnection(client);       
            trace("TEST");
    Step 2 : Save the file under the folder underneath FMS's applications directory
    Example : FMS\application\dyn
    More info : http://www.flashcomguru.com/articles/fms2_basics.cfm
    Step 3: Start the FMS server. If there is a problem, check the log file
    Example : FMS\logs\_defaultVHost_\dyn\_definst_\application.00.log
    Step 4 : (optional) Change the value of the variable bandwidth for your test. I put in comment some common internet connection speed converted in bytes.
    That's all,

  • DynamicStreamingResource and Error: Playback failed with certain media

    I'm running into an issue with a DynamicStreamingResource wherein, with certain media, I receive a Playback failed error after about 20 seconds of playback. The error does not appear with these assets, which play back perfectly:
    _dynamicStreamingResource = new DynamicStreamingResource("rtmp://cp67126.edgefcs.net/ondemand");
    _dynamicStreamingResource.streamItems = Vector.<DynamicStreamingItem>(
    [ new DynamicStreamingItem("mp4:mediapm/ovp/content/demo/video/elephants_dream/elephants_dream_ 768x428_24.0fps_408kbps.mp4", 408, 768, 428)
    , new DynamicStreamingItem("mp4:mediapm/ovp/content/demo/video/elephants_dream/elephants_dream_ 768x428_24.0fps_608kbps.mp4", 608, 768, 428)
    , new DynamicStreamingItem("mp4:mediapm/ovp/content/demo/video/elephants_dream/elephants_dream_ 1024x522_24.0fps_908kbps.mp4", 908, 1024, 522)
    , new DynamicStreamingItem("mp4:mediapm/ovp/content/demo/video/elephants_dream/elephants_dream_ 1024x522_24.0fps_1308kbps.mp4", 1308, 1024, 522)
    , new DynamicStreamingItem("mp4:mediapm/ovp/content/demo/video/elephants_dream/elephants_dream_ 1280x720_24.0fps_1708kbps.mp4", 1708, 1280, 720)
    However this set of assets do not work:
    _dynamicStreamingResource = new DynamicStreamingResource("rtmp://flashstream.adobe.com/ondemand");
    _dynamicStreamingResource.streamItems = Vector.<DynamicStreamingItem>(
    [   new DynamicStreamingItem("mp4:flash/m/mv1/acom/connectnow/flvs/acom014_854x480.flv", 408, 854, 480)
    , new DynamicStreamingItem("mp4:flash/m/mv2/acom/connectnow/flvs/acom014_854x480.flv", 608, 854, 480)
    , new DynamicStreamingItem("mp4:flash/m/mv3/acom/connectnow/flvs/acom014_854x480.flv", 908, 854, 480)
    I've confirmed that each asset individually plays as desired, which they do.
    Additionally, I have noticed that the buffer grows at an awkward rate - it jumps to about 10 seconds, stutters back and forth between 15 and 20, then stalls, and eventually jumps to 40 seconds, at which point the playhead, around 20 seconds, stalls and I receive the Playback failed error. This happens 100% of the time.
    Any thoughts as to why the second set is problematic?
    Thanks!

    I'm getting "NetStream.Play.StreamNotFound" when I try to play your first stream so I'm not able to investigate this. Here are some things to look at:
    The bitrate you give to DynamicStreamingItem is very important. It must be accurate with regard to the encode. The switching rules use this value to throttle the connection between client and server to keep the buffer from growing too large. Make sure your encodes are CBR and not VBR (variable bitrate). Make sure all encodes have the same keyframe interval. Make sure you set your buffer to 8 seconds initially to get this working. You can adjust if you wish.
    Also, turn logging on and start digging through the logs. Determine which stream playback is failing on. The next thing I would try is put the bitrate in the stream name and put them in the same location on the server rather than different paths for each bitrate.
    Thanks,

  • Safari with Windows Media Player cannot use PHP as filename/src/url

    I'm running Windows XP Pro SP2 with Windows Media Player 11
    and Safari 3 public beta. In addition to being the absolute
    slowest browser among MSIE, Firefox, Netscape, and Opera, the
    Safari browser has two annoying WMP defects.
    1) Even with WMP 11 installed, the code below for embedding
    can use either the classid for WMP v6.4 or v7+ but Safari
    (or rather it's plugin) always displays a v6.4 looking UI.
    All other browsers display the media player using the v11 UI
    2) Safari will not download the movie if the "filename" param
    is a web url (e.g. getmovie.php?select=1234 ) rather than the
    precise name of the movie file itself (e.g. "movie.wmv"). The
    other browsers may differ in use of the param name="xxxx", where
    xxxx is "filename" or "src" or "url" or "data" ... but Safari
    will not work using any of these.
    Has anyone successfully embedded a WMP object that uses the
    URL as a PHP page (or other server-side script) ? I have already
    my server-side PHP code that works perfectly for MSIE, Firefox,
    Netscape, and opera. Safari is the only problem browser.

    I have run into several issues pointing to what you are describing...
    I fixed my Safari by installing the WMP plugin. I am able to view visualizations embedded into a webpage, one of which I created...I am able to view videos and so on.. Before I installed the plugin, All that would load is a place holder which looked like the old WMP and would not function properly. However this is what is displayed beside the media which is embedded.
    I think that I got the plugin by going to the download page for Safari and looking for plugins. Funny thing was that the plugin that I installed was the one for Firefox on its site that nobody every installs because Firefox gets the plugin if you already have WMP11 installed. Anyway this should solve your problem...with most..
    I have noticed just now that PHP served links or applications which launch in their own window and are protected by PHP script do work but still display a lack of functionality showing the Version 6.4 that you are speaking of. I checked it out using the KDGE Live Stream which opens another window, and displays version 11 properly ( in other browsers ), the link which is served is also protected and will close any media player that tries to play it on its own. It soley depends on the script which is coded into the page or window for the player. I can see this method as useful for a corporation as large and well advertised as ClearChannel Productions, because of the lack of bandwidth and cost to the company. Several sources do this and it winds up being an issue for the website administrator and designers to take care of, or update the script, or the person who has written the plugin, which could be from a number of resource; this particular instance would be the author of the WMP Plugin for Firefox.
    For any other purpose though the plugin I mentioned above should get rid of ( MOST ) of that problem.

  • "Error loading media. File Could not be played"  when trying to view streaming media on only some sites.  How to fix?

    Hi!
    I've been having a problem trying to view streaming media, but it only happens on some sites.  It's similar to a problem I have on my Windows PC, that's related to Adobe Flash, but since I'm very new to using my iPad Mini, I don't even know if Apple devices have Flash...do they?
    Anyway, when I go to a site that's plagued by this issue, I tap the 'Play' arrow on my screen & the circle spins like it's gonna play, but then the screen turns black & this error message appears:
                                                  "Error loading media. File Could not be played"  followed by a triangle with an exclamation point !
    I read several articles online & the solutions ran from updating firmware in their router, (mine is brand new...installed last Thursday), to disabling ad-block programs in their browsers...(I don't have any enabled), and the last one was making changes to the DNS...(I know it means 'domain name server', but I don't have the foggiest idea how to make changes to it!
    Anyway, that's my problem.  I hope that someone out there knows what I can do to fix it!
    Thanks in advance for your help.

    I would assume an issue with the HTML5 media player.
    If those aren't working on Windows then it is possible that the proper codecs aren't installed.
    You can try to disable the HTML5 media player and make Firefox use the Flash plugin.
    You can do this by setting these two prefs to false on the <b>about:config</b> page:
    *media.windows-media-foundation.enabled
    *media.directshow.enabled

  • New wiki page on 'streaming media'

    Hi there,
    I have created a new page on how to stream media over the network. It seemed like a good idea to centralize knowledge on this topic on 1 page, even if all it held were references to more concise wikipages.
    The page is located at: http://wiki.archlinux.org/index.php/Streaming_media
    1. This is my first wiki-page, so I'm sure I've done some things wrong;
    2. I will be adding more information on some of the programs I've used, but of course, you are all invited to add content or discuss the page...
    HTH!

    Hi,
    It is a really nice idea. Maybe the page ought to serve as a hub for other articles.
    A couple of comments on sharing medias:
    * I have not been very happy with upnp. I used it for a while when I had a Synology NAS, but the fact that it seemed to rely on some kind of index made it less attractive. Samba has treated me nice; it always works (as oppose to "real" Windows shares which is a drag to setup).  I use samba for sharing videos and pictures to XMBC4Xbox.
    * For streaming live audio output, i.e. what is playing *right now* on my laptop to my stero, I have found a combo of icecast, pulseaudio and gstream to work nice. For serving static audio files I use squeezeboxserver. Had I used a Sonos sound system I would have used Samba again.
    * For PS3, which is a somewhat limited device, there is a nice java application that takes care of everything.
    * What I really miss is some way to preserve metatags when downloading video podcasts. To me it does not matter much at the moment as xbmc does not support local rss feeds. . . 
    I could add some comments on some of the above if you think it fits into your article.

  • Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

    Hi all,
    Shortly after upgrading from Linux 3.11.6 to 3.12, I started getting kernel panics while playing streaming media (in particular from Youtube and The Daily Show). Here is a camera shot. The crash would not take place immediatly, but perhaps after 15 minutes of streaming. After downgrading to Linux 3.11.6 everything works fine. Therefore, it is clear to me that the issue is related to the Linux 3.12 kernel, but this is all I know.
    The fifth-to-last line from the camera shot reads:
    [11438.332699] RIP [<ffffffff8129e160>] __sg_page_iter_start+0x20/0x20
    A quick Google search reveals that __sg_page_iter_start is a function inside the scatterlist.h library in the Linux kernel, which apparently deals with memory paging, but my knowledge about this stuff is so poor that the message is almost meaningless. I would greatly appreciate if someone could give me a hint about this.
    I did not find anything useful in the journal, but here are the last few journal lines for 2 different crash instances:

    In the first journal log, the following line calls my attention:
    Nov 15 00:26:02 xps kernel: perf samples too long (2530 > 2500), lowering kernel.perf_event_max_sample_rate to 50100
    However, this seems to be a normal occurrence after playing games (https://bbs.archlinux.org/viewtopic.php?id=170471), so I would guess this is not related to the kernel panic.
    For reference, here are some hardware specifications of my Dell XPS 13:

    Posted to [email protected], I hope I just haven't dawdled for too long and this can make it to 3.13 final.
    Hopefully this should be sufficient information, I've linked to this thread too.  I've also mentioned I'm willing to beam one at someone from Amazon, with 2-day shipping to the USA the Pluggable branded adapter is just under NZD$40, which I can easily live with.
    ===========================================================================================================
    USB3 gigabit ethernet adapters with the ASIX AX88179 chipset (LevelOne USB0401-V3, Plugable USB3-E1000, SIIG JU-NE0211-S1 and others) are experiencing kernel panics in usb_hcd_map_urb_for_dma since 3.12.  The issue does not seem to directly correlate with low or high network activity, occurring seemingly at random.  Some panics occurred less than 5 minutes from boot and tens of megabytes of network transfer, while on other occasions it would be stable for multiple days with tens to hundreds of gigabytes of line-rate throughput and several sleep/resume cycles.
    Both my Sony Vaio Pro 13 and another user reporting this issue on the Arch forums [1] are Intel-based, my USB controller is an 8086:9c31 (Lynx Point LP), the other is reported as a C210/7 series (unknown PID).  A third with a Haswell Dell XPS has attempted my workaround and reports similar success.
    I have a mediocre quality photo of my laptop's screen from one of these panics [2], the call trace - which is similar but not identical between my machine and that of the other user reporting the issue - is as follows:
    usb_hcd_map_urb_for_dma
    usb_hcd_submit_urb
    local_bh_enable_ip
    selinux_parse_skb
    usb_alloc_urb

    fget_light
    SYSC_sendto

    system_call_fastpath
    So far as I can tell, the driver is unaffected as late as 3.11.6, but problematic as of 3.12 (and still affected in 3.13-rc5).  The history of drivers/net/usb/ax88179_178a.c for this time period yields this patch, which at least in my somewhat limited understanding appeared a likely candidate.  I've reverted this on my system - against several linux-next builds from the last 3-4 weeks - and have had no issues with this network controller since.
    commit 3804fad45411b48233b48003e33a78f290d227c8
    Author: Ming Lei <[email protected]>

        USBNET: ax88179_178a: enable tso if usb host supports sg dma
        This patch enables 'can_dma_sg' flag for ax88179_178a device
        if the attached host controller supports building packet from
        discontinuous buffers(DMA SG is possible), so TSO can be enabled
        and skb fragment buffers can be passed to usb stack via urb->sg
        directly.
        With the patch, system CPU utilization decreased ~50% and throughput
        increased by ~10% when doing iperf client test on one ARM A15 dual
        core board.

    Unfortunately I have not retained the built kernel from a broken 3.12 build, so the system information below reflects the patched linux-next kernel I am running currently.
    I understand this may be a somewhat obscure piece of hardware, I am willing to assist by drop-shipping one to someone from Amazon (or local country equivalent if the price is not extortionate) should it be required.
