XGrid and ffmpeg

Has anyone tried setting up xgrid to run ffmpeg for encoding video?
I've got alot of video that I need to encode and speed could be greatly improved with xgrid.

I've started playing around with XGrid myself and tried to export some video using QuickTime tool.
You can download QT_TOOLS here:
http://www.omino.com/~poly/
and have more tech info about it here:
http://www.omino.com/~poly/software/qttools/man/qtexport.html
Still haven't found the perfect line command for that, but this tool is powerful and should give you what you are looking for with ffmpeg.
Hope it works out well for you.

[solved]Update of x264 and ffmpeg breaks MPD

Updating to x264-20100107-1 and ffmpeg-20100108-2 had a bad effect on MPD today
error while loading shared libraries: libx264.so.67
error while loading shared libraries libavutil.so.49
Were the error I got after update when trying to start mpd.
Rather than do the ugly ls -s fix I'll wait for a rebuild/fix.
Anyone else??

I've not pulled in my msg from arch-dev-public in last 24 hrs or so... my bad.
I at least did ask in #archlinux and got no response before posting here.

good... I somehow knew if I posted this to begin w/ MPD would be rebuilt/uploaded soon soon after I posted.

XGrid and DVD Studio Pro

Greetings all,
I've searched the net for an answer to this and couldn't find one, although I'm sure this question has been asked hundreds of times before. I just finished sorting through this forum as well and couldn't find a similar question. It doesn't seem like this forum is too active, but I'll give it a shot anyway.
I use Final Cut Pro HD (4.5) and DVD Studio Pro 3 rather heavily. We have four systems and may have a new addition soon. I'd really love to be able to speed up render times in DSP at the very least.
So far I've set up the grid. I used XgridLite to make one of the computers the controller. Through Apple Preferences I enabled Xgrid on the agent systems (including the controller) and pointed them to the controller system. The grid is password-protected, and all agents are set to receive tasks regardless of whether they are idle or not. With the exception of one system (the slowest one), all systems successfully joined the grid and are in "Available" status when viewed with Xgrid Admin.
I presume the grid is properly set up so far. When I try to encode with DVD Studio Pro, however, the admninistrator utility doesn't show any of the systems becoming active. Note that the primary encoding system was the same as the controller system - was that the problem, perhaps?
All systems are currently linked through a 100 mbps network. We'll soon be moving them to a 1 gbps network. I was hoping that the 100 mbps network would at least let me see that it worked, even slightly. I looked through DSP's preferences but I can't find any options about network encoding or tying into Xgrid. I presume that acting as a client to the Xgrid network is a function built into Xgrid-enabled programs (or scripts you'd write yourself).
Any advice? If anyone can say for certain that DSP 3 won't do it but that newer versions of DSP will, I can request an upgrade and probably get it. I'd rather not do that unless this will for sure work with Xgrid, and only if Xgrid will provide a reasonable performance boost.
Thanks in advance!
David

This post has received a number of views but no comments back, so I thought I'd give a brief update on my findings. Even though I've seen Xgrid as being marketed as something that could be used for media, it is the wrong tool for the job when it comes to Final Cut Pro, DVD Studio Pro, and likely other media applications. What should be used instead is a program called Qmaster. If you have DVD Studio Pro 4, Qmaster is included in the "Extras" content on the disc. Qmaster allows for distributed work to occur through Compressor, which Final Cut Pro and DVD Studio Pro rely on.
I have requested that my department upgrade to DVD Studio Pro 4, and may update with how successful it is. Otherwise, if you were like me and were looking around the internet for how to get this stuff working with Xgrid, stop and begin looking into Qmaster.

Reading InputStream from Runtime.exec() and ffmpeg?

I've got a lot of things going on here and I'm having trouble debugging. I'm working on a streaming music player, and the platform only handles MP3 natively. Specifically, the method that handles incoming requests has to return an InputStream for further processing upstream (out of my visibility).
I'm trying to extend the music player to play AAC files with the extension ".m4a". To do this, my plan is to transcode from MP3 to AAC using Runtime.exec() and ffmpeg, and then return an InputStream that contains the MP3. This works fine if I use ffmpeg to transcode to a temp file, and then return a FileInputStream constructed from that temp file. But like I said, this is supposed to be a steaming music player, and the blocking for the ~30 seconds it takes to completely transcode to a file is too much of a delay.
So what I'm trying to do is have ffmpeg transcode to stdout, and then use Process.getInputStream() to return the InputStream that contains ffmpeg's stdout while the transcoding is still going on. This doesn't work and I'm not sure why. (I'm fairly new to java, and this is the first time I've used Runtime.) My player just hangs there. I know Runtime is picky about exhausting the stdout and stderr streams, so I'm not sure if it's something related to that, or if I somehow need to buffer the stdout before returning it, or if I need to run something in a different thread, or if I'm just completely barking up the wrong tree.
If anyone has any experience with something like this, or can point me at some code that implements something similar, I'd appreciate the help.
Below a sample of the code in question. Also, for what it's worth, all of the console messages that I put in there are printing, but the music doesn't play.
   public InputStream getStream(String uri) throws IOException
             System.out.println("Entering Factory.getStream()");
              System.out.flush();
            File file = new File(URLDecoder.decode(uri, "UTF-8"));
            if (file.exists())
                 if(file.getPath().toLowerCase().endsWith(".mp3")) {
                        // This code for playing MP3 files works correctly
                      System.out.println("Playing MP3");
                      System.out.flush();
                      InputStream in = new FileInputStream(file);
                      return in;
                 else if(file.getPath().toLowerCase().endsWith(".m4a")){
                      System.out.println("Playing M4A");

Help needed with JMF and FFMPEG

Hi, im using Jave which is a wrapper libraray for FFMPEG to encoded videos and im also using JMF to take snapshots of the video to save as thumbnails. All the code I have works except that I cant get Jave(FFMPEG) to encoded the videos in to a format that JMF can handle. Does any body know a format or codec that Jave(FFMPEG) can use to get JMF to handle the videos.
Cheers, any help will be much apprecitated.

One solution to most of your questions : Read the advanced table section of Dev guide.
Always go through the dev guide before putting up the issue. Let the forum be for those scenarios which dev guide doesn't covers in much detail.

XGrid and Final Cut Pro

hey peeps,
I was wondering if Final Cut Pro would benifit from xgrid. We have 4 Mac Pros for the video guys and they would find it useful if they could share resources, especially if one individual is not using there machine to its full potential.
If users did a traditional render would it utilise a clusters resources rather than just one machines or would i have to run the render via command line?
Also, would Adobe Creative Suite users benifit from setting up xgrid?
Cheer in advance

Final Cut Pro does not use Xgrid unless something's changed very recently. FCS comes with a different distributed processing technology, Qmaster, which allows Compressor processing to be distributed to multiple systems. You can find documentation here (that may not be the latest, but it will give you the idea, at least).
Adobe Creative Suite has no distributed processing capability, to the best of my knowledge.
Regards.

Xgrid and Apple apps

FinalCutPro?
Motion?

Re: After installing Yosemite, safari doesn't work any more.in response to Koenfromdudzele
I have found a temporary solution that works until reboot.
Open a Terminal window and type:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
-type password-
then:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
Dont know how to link him. But this worked fine. Guess it was missing this plist

XGrid and Super Pi

Can I use xGrid to impove my time in Super Pi? Also, is there any decent beanchmark tool for OS X that works with a cluster in xGrid?

I don't know if super_pi is the ideal software to benchmark a MacBook Pro, as there is no Universal Binary version nor sources today (or if you have found something, give us the link !)
If you want to try with the Windows version under bootcamp, or using Roseta here is the homepage :
http://www.super-computing.org/
Also, to calculate 2M digits of Pi, you'll have to use 21 as the parameter.

FCP and xgrid system?

I am new to FCP and xgrid and I am planning on getting FCP later in the spring. My question is, for someone who has expereince with xgrid, how well does FCP utilize an xgrid system? Also could an xgrid system be possible over a wireless G network or is this way to slow? I have a powerbook as my main computer and I could utilize a mac mini, iMac G5, and some windows computers (if possible) all as clients on the xgrid system... IS this possible?
Also if you just have an xgrid system please elaborate about its infrastructure/setup, how well it works, opinions, etc...
Thank you in advance,
TM

FCP at the present time makes no use of the xgrid renderfarm capability...

FFmpeg crash when recording desktop

I'm using x264-git and ffmpeg-svn from AUR. I am attempting to record usage of xcalc as an example of using FFmpeg to capture a specific application on the desktop. However, FFmpeg will always crash at certain resolutions, but it will encode if I change the resolution from -s 228x332 to -s 232x332. I asked at #ffmpeg and nobody was able to replicate this. My system is i686.
Can anyone confirm this behavior?

I just started using GB for the very first time last night and began experiencing the same symptoms several hours into the session and it has not stopped despite a reboot. It hangs about 75% of the time after I record a track or when I try to save. Interestingly, I can still play the keyboard and hear sounds despite the spinning beach ball preventing me from doing anything through the GB GUI. I also need to use a Force Quit. I'm using a Keystation 49 (not the 49e).
I'm a recent first-time Mac owner (I've only had it for about two weeks now) and am disappointed with the problems that I've had so far. I still like it more than Windows, but it's sure not because it's more stable.

Podcast Producer and Internet Explorer

I've configured Podcast Producer on 10.6.8, and it is working fine - items are processed from the Capture software through to PcP2 and Xgrid, and are then uploaded to a Wiki.
The issue is with clients using Internet Explorer (any version) and their ability to play audio files uploaded from Capture or through the web interface of the wiki. Videos work fine, but whatever code is used to upload just audio files to the wiki cannot be interpreted by IE. I know that 10.6.8 was meant to address some of these issues, but I am just not sure how to proceed.
Has anyone had a similar experience?
Cheers
Kieran

Not sure if this will fix your problem, but I was having the same problem until I looked at the specs for XGrid, it has to run on an Intel Mac. This is where you can get the specs:
http://docs.info.apple.com/article.html?artnum=306737
Here is what is in the doc:
Podcast Capture requirements
Any Mac running Mac OS X 10.5 Leopard
iSight camera (built-in or external) or FireWire DV camcorder
Podcast Producer Server requirements
Any Mac running Mac OS X Server version 10.5 Leopard
Xsan for optional cluster file services
Podcast Producer Xgrid rendering requirements
Any Intel-based Macintosh Server or Intel-based desktop Mac (a Mac Pro, for example)
Mac OS X 10.5 Leopard or Mac OS X Server version 10.5 Leopard
At least 1 GB of memory (RAM) plus 512 MB of additional RAM per processor core
At least 50 GB of available disk space
Xsan for optional cluster file services
Quartz Extreme-enabled video chipset
Note: Quartz Extreme support can be verified in the Graphics section of Apple System Profiler.
Note: If a system is providing multiple Podcast services (for example, Podcast Producer and Podcast Producer Xgrid rendering), the system needs to meet both requirements.

Mix 10.5.8 Server and new 10.6 - Advice?

We currently are using a Leopard 10.5.8 Xserve with Dansguardian and Squid proxy to provide web access and limited wiki and calendar use for about 200 users (not all online at once). I would like to investigate serving podcasts daily to the users using the necessary services in Mac OS X Server. There is also a possibility of streaming broadcasts once a week. Workgroups have been setup and Podcast Producer works fine.
My question has to do with the load on the Xserve. While testing there does not seem a significant impact on the web access and server. However, going forward, am I better off to deploy the Podcast Producer, Xgrid, and QTSS on another server; perhaps a new 10.6 mini? If so, has anyone had experience integrating a 10.6 server with a 10.5? Are there any issues to be concerned about?

Compressor H.264 and Android devices

I'm looking to make videos on our web site as mobile compatible as is practical and have run into a specific issue with compressor. When I tried to play one of our H.264 videos on an Android device I got the picture but no sound. I did some experimenting and found that any video made with the Format of Quicktime (regardless of codec) had the same problem. I have been able to make H.264 videos with other tools such as Handbrake and ffmpeg with similar settings as used in Compressor and those work fine on the Android. Anyone have an idea what my problem is and if there is a work-around? So far my only option seems to be using ffmpeg instead of compressor.

I've had luck with H.264/AAC from Quicktime Player 7 and Adobe Media Encoder. I've never been able to export to Android out of Compressor. The AAC flavours Compressor offers aren't to Android's taste.
Here's the spec sheet on what is/isn't accepted.
http://developer.android.com/guide/appendix/media-formats.html
Also, for the record, Google supports and actively contributes to HTML5. The hang up is the video tag in HTML 5 does not specify a codec. Google is dropping support for H.264 video in Chrome when using the video tag because H.264 is proprietary, not open. This is the same reason H.264 video support has never been in Firefox. H.264 will be supported in Chrome through Flash, just as WebM will be supported almost everywhere else via Flash.
