Michael Niedermayer	89f98acbf8	avcodec/evc_ps: Check log2_sub_gop_length Fixes: 1.70141e+38 is outside the range of representable values of type 'int' Fixes: 59883/clusterfuzz-testcase-minimized-ffmpeg_BSF_EVC_FRAME_MERGE_fuzzer-5557887217565696 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago

James Almer	fdd8daf899	avcodec/evc_parser: remove write only variable Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	a5663f2d9a	avcodec/evc_parser: make ff_evc_parse_nal_unit() local to the parser This is in preparation for the following commits. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	ff7a4cdf04	avcodec/evc_parse: split off deriving PoC Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	f7e0af5edc	avcodec/evc_parser: stop exporting delay and gop_size The former is a property a decoder may export, and the latter is only used in encoding scenarios. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	1e189fed7a	avcodec/evc_parse: split off Parameter Set parsing into its own file Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	4afee83d35	fate/lavf-container: add a test to remux raw evc into mp4 Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	8ab706677c	avcodec/evc_frame_merge_bsf: use av_new_packet() This ensures the buffer is padded as required by the AVPacket API. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	96fc192733	avcodec/evc_frame_merge: use av_fast_realloc() Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Anton Khirnov	1617d1a752	fftools/ffmpeg: pass subtitle decoder dimensions to sub2video Restores behavior from before `20cacfe493`. Eventually this should be handled similarly to audio/video - with a filtergraph reset or a manual scaler.	2 years ago
Anton Khirnov	88f80977eb	fftools/ffmpeg: use AVFrame to pass subtitles from decoders to filters Allows to use the same buffering code for all media types. Will also be important for the following commit.	2 years ago
Anton Khirnov	fa717baaa5	fftools/ffmpeg_enc: constify the subtitle passed to enc_subtitle()	2 years ago
Anton Khirnov	e89a6d1089	fftools/ffmpeg_dec: move InputStream.prev_sub to Decoder It does not need to be visible outside of decoding code.	2 years ago
Anton Khirnov	a45b9d35b9	fftools/ffmpeg: move fix_sub_duration_heartbeat() to ffmpeg_dec This way ffmpeg.c does not need to access InputStream.prev_sub and it can be made private.	2 years ago
Anton Khirnov	01897c1788	fftools/ffmpeg_dec: move decoding to a separate thread This is only a preparatory step to a fully threaded architecture and does not yet make decoding truly parallel - the main thread will currently submit a packet and wait until it has been fully processed by the decoding thread before moving on. Decoder behavior as observed by the rest of the program should remain unchanged. That will change in future commits after encoders and filters are moved to threads and a thread-aware scheduler is added.	2 years ago
Anton Khirnov	5293adb1a7	fftools/ffmpeg: attach bits_per_raw_sample information to frames This way avoids encoders reaching into filters or decoders for this information.	2 years ago
Anton Khirnov	7d4e00ccf0	fftools/ffmpeg_dec: stop using Decoder.pkt It is only used for flushing the subtitle decoder, so allocate a dedicated packet for that. Keep Decoder.pkt unused for now, it will be repurposed in future commits.	2 years ago
Anton Khirnov	1bdd53e2f9	fftools/ffmpeg_filter: make configure_filtergraph() static It is no longer used outside of ffmpeg_filter.	2 years ago
Anton Khirnov	b1a213ab5d	fftools/ffmpeg_filter: reject filtergraphs with zero outputs Nothing useful can be done with them currently.	2 years ago
Anton Khirnov	a7aa05c599	fftools/ffmpeg_filter: add an AVClass to FilterGraph Use it for logging.	2 years ago
Anton Khirnov	a934392db0	fftools/ffmpeg_enc: move dup_warning global variable to Encoder	2 years ago
Anton Khirnov	1adad44fc7	fftools/ffmpeg_dec: move InputStream.hwaccel_pix_fmt to Decoder It is purely decoder-internal state.	2 years ago
Anton Khirnov	174cb3accf	fftools/ffmpeg_dec: remove pointless InputStream.hwaccel_retrieve_data It is always set to hwaccel_retrieve_data() from ffmpeg_hw.c, so that function can just be called directly instead.	2 years ago
Anton Khirnov	25d96ab6c0	fftools/ffmpeg_hw: inline hwaccel_decode_init() into its caller The function is now trivial and cannot fail, so all error handling in its caller can be removed.	2 years ago
Anton Khirnov	6c9cbf7507	fftools/ffmpeg_demux: reindent after previous commit	2 years ago
Anton Khirnov	98766dbbd7	fftools/ffmpeg_demux: move the loop out of add_input_streams() Make the function process just one input stream at a time and save an indentation level. Also rename it to ist_add() to be consistent with an analogous function in ffmpeg_mux_init.	2 years ago
Anton Khirnov	47a14b542e	tests/fate: add a test for -streamloop with transcoding video+audio	2 years ago
Anton Khirnov	90a26e75a4	tests/fate: rename ffmpeg-streamloop to ffmpeg-streamloop-copy Makes it clear that this tests -streamloop with streamcopy, to distinguish it from further -streamloop tests added in future commits.	2 years ago
Anton Khirnov	df81fb46ee	fftools/ffmpeg_dec: simplify process_subtitle() Its got_output argument always points to 1.	2 years ago
Anton Khirnov	e9eb44ed88	fftools/ffmpeg_dec: drop always-0 InputStream.prev_sub.ret	2 years ago
Anton Khirnov	52d7ea6635	doc/ffmpeg: improve -stats_*_fmt documentation	2 years ago

Zhao Zhili	f66e1862e3	avcodec/videotoolboxenc: inherit profile from AVCodecContext This can happen when user set the avctx->profile field directly instead of specify profile via option. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	3fafc842f1	avcodec/videotoolboxenc: remove AUTO_PROFILE define Use FF_PROFILE_UNKNOWN as auto mode. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	315c66af0f	avcodec/videotoolboxenc: use int as the type of profile Other than save a few bytes, it also has the benefit to show the AV_OPT_TYPE_CONST value in help, e.g., -profile <int> E..V....... Profile (from 0 to INT_MAX) (default 0) baseline 66 E..V....... Baseline Profile ... Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	fb85aa959a	avcodec/mediacodecenc: add profile names to options H.264 high10/high422/high44 are unlikely supported by devices. It's there for developers to do the experiment. H.265 main10 works on my device with AV_PIX_FMT_MEDIACODEC. OMX_COLOR_FormatYUV420Planar16 doesn't work. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	e349b45fa0	fate/cbs: add tests for discard_units Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	4a00cd4fe3	avcodec/filter_units_bsf: reindent after previous commit	2 years ago
Zhao Zhili	dfa0e24e98	avcodec/filter_units_bsf: add skip frame support	2 years ago

Zhao Zhili	e7cde0cbd5	avcodec/cbs_h2645: add discarded_unit implementation for H.264	2 years ago
Zhao Zhili	a8aeab107e	avcodec/cbs: add API to discard units by AVDiscard	2 years ago
James Almer	5e9986fd2d	avformat/evc: use get_ue_golomb_long() Fixes compilation of shared libraries, as well as correctly parses width and height values. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Michael Niedermayer	9fc141f32d	avformat/jpegxl_anim_dec: Perform operations in a different order Fixes: OOM Fixes: 59802/clusterfuzz-testcase-minimized-ffmpeg_dem_JPEGXL_ANIM_fuzzer-5681765466112000 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	2 years ago
Leo Izen	61047f0f82	avformat/jpegxl_anim_dec: avoid overrun with jxlp boxes in container This switches the jpegxl_collect_codestream_header function to use avcodec/bytestream2, which better enforces barriers, and should avoid overrunning buffers with jxlp boxes if the size is zero or if the size is so small the box is invalid.
