Thomas Siedel	aa3155e4c2	avformat/mp4: add muxer support for H266/VVC Add muxer for vvcc byte stream format. Add AV_CODEC_ID_VVC to ff_mp4_obj_type. Add AV_CODEC_ID_VVC to ISO Media codec (VvcConfigurationBox vvi1, vvc1 defined in ISO/IEC 14496-15:2021). Add VvcConfigurationBox vvcC which extends FullBox type in ISO/IEC 14496-15:2021.

Lynne	5860a966d2	lavfi/vsrc_testsrc_vulkan: fix -Wint-conversion While VK_NULL_HANDLE is equivalent to NULL on 64-bit platforms, the same is not true across all platforms. Fixes building with gcc-14.	10 months ago
James Almer	9949c1dd78	avformat/avformat: fix group index range check in match_stream_specifier() Fixes segfaults when trying to map a group index with a value equal to the amount of groups in the file. Signed-off-by: James Almer <jamrial@gmail.com>	10 months ago

Frank Plowman	36a986d9a1	lavc/vvc: Add check to num_multi_layer_olss Check that vps_each_layer_is_an_ols_flag, which indicates that "at least one OLS specified by the VPS contains more than one layer," is set if num_multi_layer_olss is non-zero.

Anton Khirnov	093be1fb06	fftools/ffmpeg: cosmetics, vertically align Input{File,Stream}	10 months ago
Anton Khirnov	f4b76a1d6a	fftools/ffmpeg: make InputStream.decoder_opts private to demuxer It is no longer used outside of ffmpeg_demux.	10 months ago
Anton Khirnov	01c71b78eb	fftools/ffmpeg: make InputStream.decoding_needed private to demuxer It is no longer used outside of ffmpeg_demux.	10 months ago
Anton Khirnov	0d00e2e2f7	fftools/ffmpeg_dec: eliminate all remaining InputStream uses Previously, the demuxer would register decoder with the scheduler, using InputStream as opaque, and pass the scheduling index to the decoder. Now the registration is done by the decoder itself, using DecoderPriv as opaque, and the scheduling index is returned to demuxer from dec_open(). decoder_thread() then no longer needs to be accessed from outside of ffmpeg_dec and can be made static.	10 months ago

Anton Khirnov	1b2c539a0f	fftools/ffmpeg_dec: pass AVCodecParameters through DecoderOpts Do not retrieve it from InputStream directly. This is a step towards decoupling Decoder and InputStream.	10 months ago
Anton Khirnov	b3d1916ba0	fftools/ffmpeg_dec: pass AVCodec through DecoderOpts Do not retrieve it from InputStream directly. This is a step towards decoupling Decoder and InputStream.	10 months ago

Anton Khirnov	b27de18e4f	fftools/ffmpeg_dec: move setting compute_edt to demuxer It is done based on demuxer information, so that is the more appropriate place for this code. This is a step towards decoupling Decoder and InputStream.	10 months ago
Anton Khirnov	052c83e356	fftools/ffmpeg_dec: pass forced/estimated framerate though DecoderOpts Stop reading them from InputStream. This is a step towards decoupling Decoder and InputStream.	10 months ago

Anton Khirnov	a3a9c4ae66	fftools/ffmpeg: move hwaccel_retrieve_data() from ffmpeg_hw to ffmpeg_dec This function is decoding-only and has no interaction with the rest of ffmpeg_hw. It thus belongs more properly in ffmpeg_dec.	10 months ago
Anton Khirnov	ebb8a58c8f	fftools/ffmpeg_dec: replace InputFile.format_nots with a decoder flag Reduces the need to access InputFile from decoding. This is a step towards decoupling Decoder and InputStream.	10 months ago
Anton Khirnov	a938f47916	fftools/ffmpeg: refactor disabling decoder threading for attached pictures * as this decision is based on demuxing information, move it from the decoder to the demuxer * as the issue being addressed is latency added by frame threading, we only need to disable frame threading, not all threading	10 months ago
Anton Khirnov	474ca6c71e	fftools/ffmpeg_dec: stop accesing InputStream.fix_sub_duration Pass this information to dec_open() instead. This is a step towards decoupling Decoder and InputStream.	10 months ago
Anton Khirnov	924a6f3cc7	fftools/ffmpeg_dec: override video SAR with AVCodecParameters value Rather than access the AVStream one. This is a step towards decoupling Decoder and InputStream.	10 months ago

Anton Khirnov	27de2aacd1	fftools/ffmpeg_dec: drop useless and racy code Setting demuxer's video_delay from the decoder cannot accomplish anything meaningful and is racy, as they run in different threads.	10 months ago
Anton Khirnov	9be3f80527	fftools/ffmpeg_dec: move decoding counters from InputStream to Decoder This is a step towards decoupling Decoder and InputStream.	10 months ago
Anton Khirnov	5b0e4f945e	fftools/ffmpeg_dec: pass decoder options as an argument to dec_open() Rather than access the dictionary in InputStream. This is a step towards decoupling Decoder and InputStream.	10 months ago
Anton Khirnov	7ecd45587f	fftools/ffmpeg_dec: add an AVClass to Decoder Log decoder messages to the decoder rather than InputStream. This is a step towards decoupling Decoder and InputStream.	10 months ago

Anton Khirnov	d47bb91f8b	fftools/ffmpeg_filter: consolidate decoder/filter type checks Also perform them earlier.	10 months ago
Anton Khirnov	b43d4a0692	fftools/ffmpeg_dec: export subtitle_header in Decoder This way the encoder does not need to access the decoder AVCodecContext, which will allow to make it private in future commits.	10 months ago
Anton Khirnov	3b84140a1b	fftools/ffmpeg_dec: split Decoder into a private and public part Similar to what is currently done for other components, e.g. (de)muxers. There is nothing in the public part currently, but that will change in future commits.	10 months ago

Frank Plowman	85e031d5bf	lavc/vvc: Increase IntraEdgeParams buffer size The reference line buffers are used with indices in the range -MAX_TB_SIZE - 3 to refw + FFMAX(1, w/h) * ref_idx + 1, which is at most 5*MAX_TB_SIZE + 1.

Anton Khirnov	e0da916b8f	fftools/ffmpeg: optimize inter-thread queue sizes Use 8 packets/frames by default rather than 1, which seems to provide better throughput. Allow -thread_queue_size to set the muxer queue size manually again.	10 months ago
Andreas Rheinhardt	341d0419e1	avcodec/texturedsp: Factor common code out Namely calling avctx->execute2(avctx,...). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	10 months ago
Andreas Rheinhardt	4f58372c10	avcodec/hap: Avoid unnecessary opt.h inclusion It presumably exists because HapContext contains an AVClass. Yet AVClass is actually defined in log.h and even this inclusion can be avoided by struct AVClass. This avoids opt.h inclusions in hap.c and hapdec.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	10 months ago
Andreas Rheinhardt	a3fc9fb9fb	avcodec/texturedsp: Add separate TextureDSPEncContext ff_texturedspenc_init() doesn't support most of the function types supported for decoding; add a separate context containing only pointers for the actually supported types.
