Diego Biurrun	b7e64fba7f	Reduce the scope of some variables This avoids unused variable warnings after the next version bump. Also drop a trace level av_log() call that is in the way.	9 years ago
Clément Bœsch	fb99ef0bd3	avcodec: use AV_OPT_TYPE_BOOL in a bunch of places	9 years ago
Vittorio Giovara	a17a766190	lavc: Add data and linesize to AVSubtitleRect Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
