Martin Storsjö ee37620b6a movenc: Add a flag for indicating a discontinuous fragment This allows creating a later mp4 fragment without sequentially writing the earlier ones before (when called from a segmenter). Normally when writing a fragmented mp4 file sequentially, the first timestamps of a fragment are adjusted to match the end of the previous fragment, to make sure the timestamp is the same, even if it is calculated as the sum of previous fragment durations. (And for the first packet in a file, the offset of the first packet is written using an edit list.) When writing an individual mp4 fragment discontinuously like this (with potentially writing the earlier fragments separately later), there's a risk of getting a gap in the timeline if the duration field of the last packet in the previous fragment doesn't match up with the start time of the next fragment. Using this requires setting -avoid_negative_ts make_non_negative (or -avoid_negative_ts 0). Signed-off-by: Martin Storsjö <martin@martin.st>		2014-11-26 09:56:56 +02:00

libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libavresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

avconv is a command line toolbox to manipulate, convert and stream multimedia content.
avplay is a minimalistic multimedia player.
avprobe is a simple analisys tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.
