Anton Khirnov	c0c492dd47	doc/developer.texi: extend the argument for submitting patches Stop talking about commercial programs, since this applies to any downstream user.	2 years ago
Anton Khirnov	26080d1542	doc/developer.texi: improve the introductory text Remove confusing references to "external" vs. "internal" developers.	2 years ago
Anton Khirnov	b58264217b	fftools/ffmpeg_mux_init: drop an always-false check It cannot be true since `1959351aec`. Effectively reverts `6a3833e141`.	2 years ago
Anton Khirnov	13947aff3f	fftools/ffmpeg_mux_init: use av_dict_iterate() where appropriate	2 years ago
Anton Khirnov	19e192eae6	fftools/ffmpeg_mux_init: do not call av{codec,format}_get_class() repeatedly	2 years ago
Anton Khirnov	52380a055b	fftools/ffmpeg_mux_init: move validating codec avoptions to a separate function	2 years ago
Anton Khirnov	0fb7d111e8	fftools/ffmpeg: move OutputStream.max_frames to MuxStream It no longer needs to be visible outside of the muxing code.	2 years ago
Anton Khirnov	25620b69e0	fftools/ffmpeg: stop handling max_frames in do_video_out() Frame limiting is now handled using sync queues. This code prevents the sync queue from triggering EOF, resulting in unnecessarily many frames being decoded, filtered, and then discarded. Found-by: U. Artie Eoff <ullysses.a.eoff@intel.com>	2 years ago
Anton Khirnov	6a8145a4b1	fftools/ffmpeg_mux_init: move more code from of_open() to create_streams() Specificaly, the of_add_attachments() call (which can add attachment streams to the output) and the check whether the output file contains any streams. They both logically belong in create_streams().	2 years ago
Anton Khirnov	1b076556c6	fftools/ffmpeg: simplify ost_iter() The inner loop never goes through more than 1 iteration, and so can be replaced by an if(). Found-by: Andreas Rheinhardt	2 years ago
Paul B Mahol	07357e56a6	avfilter/avf_showspectrum: fix possible hang at EOF May happen when using filter fps option.	2 years ago

Anton Khirnov	c15eb2773a	fftools/ffmpeg_[de]mux: constify all uses of OptionsContext	2 years ago
Anton Khirnov	4119480681	fftools/ffmpeg_mux_init: stop using OptionsContext as storage in copy_metadata() It should be input-only to this code. Will allow making it const in future commits.	2 years ago
Anton Khirnov	3c7dd5ed37	fftools/ffmpeg_mux_init: drop a duplicated block in copy_metadata() It does the same thing as the block right below it.	2 years ago
Mark Reid	15df8261be	avcodec/tiff: add read support for compressed rgb floating point formats floating point uses a slightly different predictor technique describe here http://chriscox.org/TIFFTN3d1.pdf Signed-off-by: Anton Khirnov <anton@khirnov.net>	2 years ago
Aidan MacDonald	a4405cc0cc	avcodec/dvdsub_parser: Fix length check for short packets The DVD subtitle parser handles two types of packets: "normal" packets with a 16-bit length, and HD-DVD packets that set the 16-bit length to 0 and encode a 32-bit length in the next four bytes. This implies that HD-DVD packets are at least six bytes long, but the code didn't actually verify this. The faulty length check results in an out of bounds read for zero-length "normal" packets that occur in the input, which are only 2 bytes long, but get misinterpreted as an HD-DVD packet. When this happens the parser reads packet_len from beyond the end of the input buffer. The subtitle stream is not correctly decoded after this point due to the garbage packet_len. Fixing this is pretty simple: fix the length check so packets less than 6 bytes long will not be mistakenly parsed as HD-DVD packets.

Niklas Haas	c0b93c4f8b	avfilter/vf_libplacebo: support all supported pixfmts This is done only to the inputs, not the outputs, because we always output vulkan hwframes. Doing so also requires keeping track of backing textures for non-hwdec formats, but is otherwise a mostly straightforward change to the format query function. Special care needs to be taken to avoid crashing on older libplacebo due to AV_PIX_FMT_RGBF32LE et al.	2 years ago
Niklas Haas	be13812a23	avfilter/vf_libplacebo: init vulkan device in query_format Instead of doing it ad-hoc in `filter_frame`. This is not a huge change on its own, but paves the way for adding support for more formats in the future, in particular formats other than AV_PIX_FMT_VULKAN.	2 years ago
Cosmin Stejerean	3b375a0c5c	lavfi/vf_dnn_processing.c: Fix missing AV_PIX_FMT_GRAY8 Has been removed by mistake in `2003e32f62`, readd it to the switch cases. Signed-off-by: Thilo Borgmann <thilo.borgmann@mail.de>	2 years ago
