[FFmpeg-devel] [PATCH] Respect payload offset in av_grow_packet

The patch fixes the function when used with reference-counted packets that have payload offset. Also this function is dangerous for not reference-counted packets because it just overwrites pkt->data. Probably it is better to restrict using it with not referenced-counted packets because you simply

[FFmpeg-devel] [PATCH 06/10] avcodec/dca_parser: improve frame end search

Parse core frame size directly when searching for frame end instead of using value extracted from previous frame. Account for unused bits when calculating sync word distance for 14-bit streams to avoid alias sync detection. Parse EXSS frame size and skip over EXSS frame to avoid alias sync

Move this from separate structure field to a packet flag. Behavior should be equivalent, except that residual flag is now properly cleared when packet has no core frame at all. Also print a message when forcing recovery mode due to invalid residual to make debugging easier. ---
