wm4	87a051f976	lavc: allow asynchronous decoders to return correct pkt_dts values The generic code in utils.c sets the AVFrame.pkt_dts field from the packet it was supposedly decoded. This does not have to be true for a fully asynchronous decoder like mmaldec. It could be overwritten with an incorrect value. Even if the decoder doesn't determine the DTS (but sets it to AV_NOPTS_VALUE), it's impossible to determine a correct value in utils.c. Decoders can now be marked with FF_CODEC_CAP_SETS_PKT_DTS, in which case utils.c won't overwrite the field. The decoders are expected to set this field (even if they only set it to AV_NOPTS_VALUE).

Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	c40ecffd31	Replace AV_PKT_DATA_QUALITY_FACTOR by AV_PKT_DATA_QUALITY_STATS The stats are a superset of the quality factor, also allowing the picture type and encoder "PSNR" stats to be exported This also replaces the native by fixed little endian order for the affected side data AV_PKT_DATA_QUALITY_FACTOR is left as a synonym of AV_PKT_DATA_QUALITY_STATS Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Vittorio Giovara	117b432748	lavc: Introduce AVCodec internal capabilities This field is designed for marking codec properties useful to lavc internals. Two internal capabilities are added: - FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks; - FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.	10 years ago

Anton Khirnov	37a749012a	lavc: rework handling of refcounted_frames=0 Use only proper AVFrame API (no assigning of whole frames, since that hardcodes sizeof(AVFrame) into lavc). Make a copy of the side data, so the caller can use av_frame_unref/free on non-refcounted frames, eliminating the need for avcodec_get_frame_defaults()/avcodec_free_frame().	11 years ago
