d8b3375f48 we don't want to archive recordings in which there's no mark to start the recording; it would be the same as if the meeting would be created with record=false - the only difference is that the events are archived to recordings/raw/meeting_id/events.xml, and the recorded .done flag is created as well 2013-10-02 14:18:26 -03:00

00d4c69f78 Fix audio processing issue 
Fix an issue that occurs on processing recordings with no audio

32b52fefb8 start and stop recording marks are being considered in all medias (audio, video and deskshare); still needs to figure out the inconsistency when the last participant leaves the conference while it's being recorded, but couple of seconds later another participant joins the meeting; the problem is that after the last user leaves the conference, the scope is deleted so the recording flag is lost, and when the scope is created again, the recording flag has the default value, that is false; also, what should we do if the user doesn't click on the recording button? how to differentiate recordings made in a version with or without the recording button? 2013-09-25 00:34:15 -03:00

cf8b31591c this commit is an unfinished work; the new code that generates the audio and video files in the recording is being adapted to take into account the recording marks; the audio is done, but video and desktop sharing is still missing 2013-09-24 18:03:12 -03:00

42e195bbe8 Rewrite the audio/video encoding components for BigBlueButton. 
I've been working on this for a while, and it's adapted from code that
has been fairly well-tested on a wide variety of recordings. I've found
it to do a more accurate job of combining multiple webcam files, and it
should be more accurate in the audio as well.

Another key feature is that it does fewer re-encoding steps during video
processing, which should both speed it up and hopefully improve quality.
The settings on the VP8 encoder have been tuned somewhat as well.

This helps maintain audio sync with video and events when freeswitch's
internal timing differs from red5's.

a5091ba3e8 RaP: Remove the ffmpeg version check, hardcode arguments for 0.11+ 
For BigBlueButton 0.81, we just require that you install ffmpeg 0.11.x
for recordings to function correctly. I'll also add a check to bbb-conf
to verify that the correct ffmpeg is available.

d63fbac298 Create missing start events for webcam streams fix #1561 2013-06-20 15:45:26 -05:00
Felipe Cecagno
fea7486ae3 implemented the possibility to include the desktop sharing streams to the presentation playback; it composes the presentation video file just like the other video streams, with the difference that while the screen is being sharing, it appears as the unique video stream in the presentation video - when the presenter stops sharing his screen, the other videos populate the video display; 
also, the output video resolution is modified to the highest screen resolution shared during the conference, independently on the output video resolution set by the user; it was done to preserve the quality of the desktop sharing image; if there's no desktop sharing, the output video resolution is respected

8ca4e949aa modified the BigBlueButton.execute method so it can raise an exception when the command passed didn't finish successfully; you can optionally pass fail_on_error=false so it won't raise an exception 2013-06-14 17:39:29 -03:00

53c071ddc3 ref #1516 
Refactored the code that generates the video file used in the presentation playback. The problem with the sync of video sources was related to problems of precision inside FFmpeg (sometimes the script runs FFmpeg to trim video files, and the output video file trimmed sometimes was 3+ seconds bigger or smaller than the requested).
Also it's a little more modular, so it will be easier to expand functionality. The processing steps are more explicit now, and the logs are better now to understand the final output.
A new parameter on presentation.yml was added to enable the admin to add an offset for the audio stream - this is mainly useful when the session ran with h264, because the video takes longer for the client to encode, and then in the recording we can see the huge gap between audio and video.
