Michael Niedermayer	985c5f226a	avcodec/utils: check that extended data has been set correctly instead of forcing it in avcodec_decode_video2() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	999ee28124	avcodec/utils: dont depend on the channel layout in unrefcount_frame() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 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
Anton Khirnov	a1ee164869	lavc/decode_video(): always unref the frame if there is no output in decode_video Not just on failure. This is the same thing that is done in the audio path and should prevent leaks in decoders that allocate a frame, but then end up not writing into it.	11 years ago
Anton Khirnov	85f947aefb	lavc: remove a pointless check in decode_audio4() av_frame_unref() works fine on unallocated frames.	11 years ago
Anton Khirnov	d4f0f2d1e8	lavc: use buf[0] instead of data[0] as the indicator of an allocated frame data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Anton Khirnov	e5419709f5	lavc: remove the extended_data workarounds. All decoders should now handle it properly.	11 years ago
Michael Niedermayer	133fbfc781	do O(1) instead of O(n) atomic operations in register functions about 1ms faster startup time Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	fdc0b3f8c1	avcodec/utils: remove unused variable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	01923bab98	avcodec: move end zeroing code from av_packet_split_side_data() to avcodec_decode_subtitle2() This code changes the input packet, which is read only and can in rare circumstances lead to decoder errors. (i run into one of these in the audio decoder, which corrupted the packet during av_find_stream_info() so that actual decoding that single packet failed later) Until a better fix is implemented, this commit limits the problem. A better fix might be to make the subtitle decoders not depend on data[size] = 0 or to copy their input when this is not the case.	11 years ago
Ben Boeckel	34b7c82dd3	avcodec/utils: use the unpack_dictionary function Signed-off-by: Ben Boeckel <mathstuf@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago
Anton Khirnov	da6506c607	lavc: move AVCodecContext.pkt to AVCodecInternal It's a private field, not meant to be accessed from outside lavc.	11 years ago
Anton Khirnov	38ecc3702d	pthread: store thread contexts in AVCodecInternal instead of AVCodecContext It's a private field, it should not be visible to callers. Deprecate AVCodecContext.thread_opaque	11 years ago
Stefano Sabatini	a689560428	lavc: remove dead FF_API_AVCODEC_OPEN API	11 years ago
Anton Khirnov	0f6c1d6d64	lavc/utils: stop using deprecated avcodec_set_dimensions	11 years ago
Anton Khirnov	7644f5a807	lavc: replace avcodec_set_dimensions with ff_set_dimensions avcodec_set_dimensions() is supposed to be an internal utility function, there is no reason whatsoever for it to be public. Therefore deprecate it.	11 years ago
Anton Khirnov	b9589f5a77	lavc: add error checking to apply_param_change.	11 years ago
Marton Balint	dbe6f9f2c2	lavc: add support for CODEC_CAP_DELAY in subtitles This patch adds CODEC_CAP_DELAY support to avcodec_decode_subtitle2. For DVB teletext decoding, a single teletext packet can contain multiple teletext pages. In order to support that, the teletext decoder may buffer some pages.

Vignesh Venkatasubramanian	0f99aad80f	lavc: Adding seek_preroll to AVCodecContext seek_preroll field is added to the AVCodecContext struct.
