DVRCast Cache/Recorded Streams Location

Where does FMIS 3.5.2 store recorded streams?
I am running FMIS 3.5.2, FMLE 3 ("Record"), and DVRCast 1.1. I have tried numerous settings, e.g., setting <StreamManager><StorageDir> and setting LIVE_DIR in fms.ini, at the application, vhost, and server level, but nothing seems to work. FMLE does not throw any errors in the encoding log and I am able to view the live stream – I do not have flash 4 or the flv 2.5 playback component so I cannot actually test the DVR feature, but I am not seeing any errors in the FMIS logs.
I have been able to successfully record streams by creating a custom FMIS application, but I would prefer to use DVRCast 1.1 because I am certain the code is more robust than mine.
Any help would be greatly appreciated.

Additionally, I can't seem to get the F4V post processor to work with these files. It is throwing an error "cannot open file" and the -v flag adds no helpful output.

Adobe Flash tried to play a live or recorded stream that does not exist. Source can't be found

NOTE: This thread was started in the flash pro forum: http://forums.adobe.com/thread/898879?tstart=0 . However, because of adninjastrators recommandation, I open the thread here:
Hello there,
I have started a stream from Flash media encoder to flash media server. According to my encoder, it should be located at: "rtmp://localhost/live" and is called livestream.
In the Flash software I try and set the source of FLVPlayback component to "rtmp://localhost/live/livestream", and I get this error: "NetStream.Play.StreamNotFound : Adobe Flash tried to play a live or recorded stream that does not exist. Source can't be found.". Both the server and encoder is runnind and I am encoding.
Too, when I try and open the html with the stream in a browser, nothing appears.
What should I check?
Thanks.
Kind regards,

Thanks for your reply.
Server, encoder and player are all on the same computer.
Admin console confirms the existence of "livestream" of type "Live" and a "NetStream" called "ABAF". No idea what the latter is.
Also, thought I'd mention that I have to start the servers from the Control Panel -> administrative tools -> services. If I try and start the server from the start menu, they dont start.
Thank you for your time.
Kind regards,
Marius

Recorded streams synchronization

We use FCS for audio conferencing.
We actually recorded all audio streams to the server from a
single meeting with many participants.
Now our problem is audio streams from different participants
gets recorded in a separate .flv file.
Now if we playback those streams they go out of sync, giving
user bad experience in case participants are discussing something
rather than a broadcast.
Is there any way we can avoid those recorded streams going
out of sync?
Any help or directions will be appreciated
Thanks in advance.

Unfortunately, there isn't a real fix for this. You can try
setting up functions that constantly compare the buffer and
playhead time of each stream, but that means everything has to stop
when one stream has an empty buffer. If other streams pause while
one rebuffers, they too have to rebuffer. Unless none of the
buffers ever empty, you'll never have sync.
Perhaps someday FMS will get a timecode system that will fix
this. I would be nice to have something like SMPTE and stream
splitting or multi source mosaic streams.
Now, if you can use progressive download for the playback
(instead of FMS), you might be able to make it work. Since the
video data is cached with progressive, you can pause one stream
while another buffers.

So just to clarify, the server is installed on the same machine that you are using to do the encoding, correct?
And you are using Flash Media Live Encoder to do the encoding?
I don't have Flash CS5 for I'm not sure what is in there to do the encoding.. but more on FMLE here:
http://www.adobe.com/products/flashmediaserver/flashmediaencoder/
There are two step used to get the encoding going with FMLE...
1. after setting all the config settings, click the "Connect" button. Then open the encoding log and you will be able to see if connection was made to the server or not. Can you successfully connect to the server? if not, what is the error message?
2. click the "Start" button and in the encoding log, you will see that the audio and video encoding has started. What does the encoding log say?

How can you record stream from a webcam like YouTube does it

We need to create a webcam stream recorder with FMS which should be able to record stream in some predefined quality (128000/bandwidth,95/quality) and will work also in the situation when the user doesn't have enough bandwidth to transfer this stream in realtime. YouTube has a solution which is using something like a buffer and when the user stops recording they continue to send video data to the server until the stream is completely recorded. We are recording the stream from our user's webcam, but when the bandwidth is not consistent or not enough, we are losing video data and ending up with poor quality recordings. What we need is that the record stream is buffered on the user's computer and the video data continues to be sent to our server even after the user has finished recording so that we end up with the complete stream (video data). We need some idea how to do this - which specific features should we used for this solution?

Does it have to be a live solution? Or can you have the user record locally and then upload to your FMS server?

How to record stream from camera like on YouTube?

Hello i would to create webcam stream recorder with FMS which should be able record stream in some predefined quality (128000/bandwidth,95/quality) and will be working also in situation if user doesnt have enough internet connection to transfer this stream in realtime. I realized that youtube has solution which is using something like buffer and when user stop recording they are still sending video data to server until stream is completly recorded. I just need some clue how this should solved and which specific features should be used for this solution?
Thank you very much for any help!

The only way to transfer photos back to a computer that were synced to your phone from a computer is to use an app like PhotoSync, which can transfer photos from any album on your phone over your wifi. (They cannot be imported using your usb cable, which only imports camera roll photos, nor can they be saved to the camera roll so the could be imported using your usb cable.)

Recording streaming videos with sound

Can I use quicktime for recording streaming videos with sound? If not which Apple software can do it?
Bye Christof

You can use Quicktime to record streaming video +with it's audio+ by using a very simple trick. Using the same cable you connect your iPod/iPhone to your car's stereo system, connect your Mac's Audio OUT to its MIKE IN jack. I used FILE / OPEN URL to select the video stream source, then selected FILE / NEW SCREEN RECORDING. In the resulting 'Screen Recording' dialog box, I set the AUDIO slider all the way to the right, and under the arrow to the right, selected "Built-in Input Line In" for the microphone. I then used the appropriate controls to play the stream and record it. The resultant file was very acceptable. Good luck.

Cached input stream?

the problem i got is that i got a lot of processes reading the same amount of bytes (6k) from disk at the same time. this will lead to the point where the IO starts blocking since it has to serve too much at once. a solution would be rading out larger chunks at once (like 100k) using something like a CachedImputStream. the CachedInputStream could be chained with a normal InputStream that reads the 6k out of it. this way the disks searches could be reduced a lot.
i was wondering if there is something like a cached input stream for java already or if i have to wirte one by myself? (note: a BufferedInputStream wouldn't solve the problem since it only tries to keep the buffer full in memory - i can't specify how many bytes to read from disk at once)

i can't specify how many bytes to read from disk at onceDo you mean the following method does not work?
read(byte[] bytes, int start, int length)?
You will probibly find that the OS reads a fixed size e.g. 8K, 16K, 32K or 64K depending on the block size of the disk regardles sof what you set. Using this option reduced the number of calls from your program to the OS, how the OS accesses the disk cannot be controlled in Java. (Your program can only provide a hint)
If performance is an issue, either reduce the number of concurrent requests or use higher performing disks such as SCSI or multiple SCSI drives mirrored/stripped.

Recording streaming audio at different quality levels with SB PC

Hi, I am trying to record streaming audio (lectures) on my computer. I have tried recording with Creative Wave Studio (ver 4.0) and Creative Recorder (ver .04). I am running windows98. This is the problem. I can record with both of these programs IF I select the 'recording format' as 'CD quality, 44,00 hz, 6 bit, stereo, 72kb/s.' However, the resulting file sizes are huge at this quality. When I change the recording format to 'Telephone quality, ,025 hz, 8 bit, mono, kb/s' I cannot record a single thing with either program. When I press record I get the following message: "RECSVR - MMSYSTEM004 the specified device is already in use. Wait until it is free and then try again." If I change back to the high quality, the error goes away. Very frustrating. I make sure that I have the right input source selected. I tried both 'wave' and 'modem' input source, but there was no change. If anyone can help me with a little guidance, that would be greatly appreciated. Thank you for help.

Hi
Can you record using mp3 or wma -format (on 28kbps) with these tools you have? These formats packs wav data to ~/0 deal from original without huge quality loss.
If not you can try if there is some other recording tools. There are also freeware products on many SW sites like

Recording stream?

Suppose I was to buy that microphone gadget for my mac. Would I be able to use it to record streams as i listen to them, for future play back? I'm thinking about perhaps recording conversations, you know when dealing with debt collection agencies for example....
With the microphone gadget you could feed the output back in and perhaps record it to mp3 or something?

It sounds to me like you are referring to iMic <http://www.griffintechnology.com>. It is esentially an external audio processor that converts analog audio into a digital signal. Is connects to your Mac vis USB.
You don't need an iMic to capture an audio stream from the internet. The iMic is useful if you want to capture audio with a microphone or from a line out jack on a cassette player, for example.
The iMic is not a microphone. It has a input jack for connecting your microphone to it.
Audio Hijack Pro is an excellent app for managing your captured audio. Also, Fission is an audio editing app that works nicely with Audio Hijack. It's features include lossless editing, ID tagging and support for adding album art. Both are shareware from <http://www.rougeamoeba.com/>.
Good luck.

NetStream.play(streamName, -1); plays recorded stream.

NetStream.play(streamName, -1);
This seems to be working wrong. For example, if I have recorded an flv on server using FMS and FMLE with only audio with name "myaudio" and then after if I try to play a live stream using NetStream.play("myaudio", -1) then it plays the recorded stream. I believe that documentation says that it should start a live stream instead of playing recorded stream as the second argument is -1. Is this a bug in NetStream.play method?

i do belive -1 says start playing the recorded video from the being saying some like NetStream.play(streamName,"live"); makes it live. look what i think up though I could be wrong I rarely use -1

Changing path of recorded streams

How can I record streaming audio???

HP HDX 18T laptop
Windows 7
NCH Wavepad sound editor
Hi, I desperately need help with this issue:
Is there anyway I can turn "OFF" the speakers so sound does not come from them, but STILL have audio levels active internally so I record streaming audio with my NCH software Wavepad program?
I've been trying everything .. in the Control Panel setup, I am trying to "capture" streaming audio with my Wavepad program, but I can only attenuate the "mic" levels that the actual laptop picks up .. for example, if there's background noise in the room, it picks that up - I DON'T WANT THAT! - I only want the streaming audio from a recording - not the background sounds in the room.
Folks at NCH Software keep telling me to check with laptop of Windows advice.
Wavepad used to do this easily and cleanly before (well, on other computers and other Windows versions)
If I go into Windows Mixer, and turn down Speakers, it also forces to turn down System Sounds - I do not want system sounds down; only speakers.
Summary:
I want to record streaming audio into my audio capture software.
I want to independantly cancel laptop speaker output, while maintaining audio levels for streaming capture.
I DO NOT want extraneous sounds in the room's background picked up by the laptop's mic, which then interferes with the recording.
(or is there a Windows program that will do this for me? I spent $$$ on the deluxe Wavepad software ,, but it's not doing what it used to do)
Any help, or advice will be GREEEEEEatly appreciated!!!
Thanks, Michael

Fixed (I think ....?)
Turns out there's no "Stereo Mix" option in my Control Panel sound boxes .. apparantly no one else has it either in Windows 7??? depending on sound card ...
Well, a work-around is to connect a male mini-plug "Y" into [one of] the laptop's headphone outs; then run a mini-plug cord (male-to-male) from it to the laptop mic "in" ... that leaves one unused female mini-plug on the "Y" .. which you can then run your headphones (or speakers ) off of.
Found that solution online .. got the parts; it works now.
Still baffled why there's no "Stereo Mix" in Windows 7 ....?

Can line in record streaming aud

I've never had an mp3 player with line in capabilities. From what I understand, line in recording can be done with CD's, etc... I was curious whether the line in could record streaming audio (such as an internet audio broadcast)? If so, I think this would be an excellent feature that would probably make the GB worthwile over the 52MB even if space wasn't too much of an issue. Thanks!?

Line-in accepts an audio line-in signal not a digital stream. You could plug the sound output from your PC into the line-in and record the stream as it is being played but you might as well just do that on the PC and transfer it as the quality will be better.
