I wrote a libAV-based application which edits a video
file. It takes a video
file as input, along with the Edit List. The input video
file is an AVI container
and was created by ffmpeg or mencoder during the
inverse-telecine step.
The Edit list contains a list of Start/Stop PTS pairs.
The output is simply
another video file based on those Start/Stop PTS pairs.
It's fairly simple. But, it ignores audio and I want to
modify it to include audio.
What can I do to make this easier to code in libAV?
Choose another container?
Also, in this thread, I might be using the words 'frame'
and 'packet' incorrectly.
With AVI files, this seems complicated since the number of
audio frames does not
always equal the number of video frames. So, I'd have to
split the audio packets or
frames into individual samples, and decide which samples
should be in the output file.
Is there an easier way? Is there a container format where
the number of audio
packets or frames exactly equals the number of video
packets? If so, this could be a lot
easier for me. Whenever I include a video frame, I would
only have to include
the corresponding audio frame. Does that make any sense?
