avcodec: add a bsf to reorder DTS into PTS
Starting with an h264 implementation. Can be extended to support other codecs. A few caveats: - OpenGOP streams are currently not supported. The firt packet must be an IDR frame. - In some streams, a few frames at the end may not get a reordered PTS when they reference frames past EOS. The code added to derive timestamps from previous frames needs to extended. Addresses ticket #502. Signed-off-by: James Almer <jamrial@gmail.com> |
