d53e7d21f3 Don't use the ffmpeg concat filter when only one audio segment 
The concat filter requires at least 2 segments, it doesn't support
the degenerate case.

7b205bdbf7 Rewrite audio processing to use ffmpeg 
There's some fairly major changes here, including:

* All audio is resampled to 48kHz stereo on input, allowing files with
  non-standard or varying rates to be mixed
* The audio processing is now done in a single pass; ffmpeg reads all
  inputs, concatenates them, and outputs one file.

c82a25f700 recording: Add a 'mkclean' step to video generation 
The 'mkclean' tool reorganizes the encoded webm file to optimize it for
streaming. In particular, it moves the index to the start of the file.

This fixes streaming in Chrome, which otherwise had a very long delay
before playback started since it downloaded until it saw the index
before it started playback.

This needs a new dependency added to the bbb-record-core package to
pull in the mkclean tool.

b91a54afa0 record core: Remove hardcoded ffmpeg path 
The ffmpeg binary should be looked up using the normal PATH mechanism,
it might not always be installed in the same place.

de0bac6f76 Skip corrupt/empty audio files when processing recording. 
Now when an empty/corrupt audio file is detected, it will be replaced
with silence.

8facc0899e Check for corrupt video files, don't attempt to render them 
A corrupt video file is defined as one where ffprobe either finds no
video stream, or it finds a video stream but cannot read any frames.

420b0b5573 Make generation of png images for pdf pages more resiliant. 
We now use ghostscript to output pngs directly from the original pdf,
rather than using convert on the split pages. This should make corrupt
or strange pdfs less likely to cause issues.

As well, if a pdf page conversion fails (for any reason, including that
the original pdf is missing...) it will be logged, and a blank page
generated, and processing will continue.

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

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

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.

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.

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
