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.

b5b81c1c4d refactored a little bit the function translateTimestamp; the images that are never displayed aren't included on the svg file anymore; still have to figure out the issue with the shapes made BEFORE start the recording - for now we cannot differentiate shapes made on the current slide and the ones made on a previous slide before start the recording 2013-09-19 15:22:22 -03:00

237268424f the timestamps of the recording events are normalized now, matching the recording marks; still need more testing when there are multiple start-stop recording events; the whiteboard actions are already working, including the slides, but slides that are outside of the recording period are still being loaded in the svg file (#TODO) 2013-09-18 17:54:51 -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.

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

Felipe Cecagno
ced61d3fba rap-worker now keeps track of the processing time of a recording; a file called processing_time is generated during the process phase, and this information is added to metadata.xml when the recording is published - this information isn't retrieved by getRecordings because no modification was done on bbb-web to include this information, but at least it's there so the sysadmin can check how long does a recording take to get processed 2013-06-13 17:13:20 -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.

80ceefa5ca presentation: Fix presentations which are images not pdfs 
This was broken by my earlier change to fallback the pdf filename for
really old recordings.

Rearrange the code so that the pdf logic is only used in the case when
the presentation is a pdf.

6083403631 RaP: Presentation: Support old recordings with '.pdf' in presentation name 
In some old recordings (0.80?) I've seen the default presentation pdf
located at the filename .../default.pdf/default.pdf. Support this old
location with fallback logic so the new scripts will work to reprocess
old recordings.

I've improved the error handling logic here a bit as well.
