* avformat/rka: Fix 1/0 with bps=1Michael Niedermayer2023-02-25
| | | | | | | | | | | | | | Fixes: division by zero Fixes: 55940/clusterfuzz-testcase-minimized-ffmpeg_IO_DEMUXER_fuzzer-6333107679920128 The decoder does not support bps=1 and i have no such sample so it is not known if this duration is correct. Alternatively we could error out on all bps we currently do not support on the decoder side or not set duration.

* avformat/mpegtsenc: re-emit extradata ahead of IDR pictures even if AUD is ↵John Coiner2023-02-19
| | | | | | | | | | | | | | | | | | | already present Current mpegtsenc code only inserts SPS/PPS from extradata before IDR frames if AUD is also inserted. Unfortunately some encoders may preface a key frame with an AUD, but no SPS/PPS. In that case current code does not repeat the "extradata" and the resulting HLS stream may become noncompliant and unjoinable. Fix this by always inserting SPS/PPS and moving AUD to the beginning of the packet if it is already present. Fixes ticket #10148.

| | | | | | | | | | FLV spec only has AVC end of sequence tag, and the EOS tag has a CodecID as other video data packet. MPEG4 doesn't conformance to the spec, but it's there for a decade.

* avformat/movenc: allow writing out channel count in MP4 and 3GPJan Ekström2023-02-14
| | | | | | | | | | | | | | | | | | | ISOBMFF (14496-12) made this field ('channelcount') in the AudioSampleEntry structure non-template¹ somewhere before the release of the 2022 edition. As for ETSI TS 126 244 AKA 3GPP file format (V16.1.0, 2020-10), it does not seem contain any references limiting the channelcount entry in AudioSampleEntry or in its own definition of EVSSampleEntry. fate-mov-mp4-chapters test had to be adjusted as it output a mono vorbis stream, which would now be properly marked as such in the container. 1: As per 14496-12: Fields shown as “template” in the box descriptions are fields which are coded with a default value unless a derived specification defines their use and permits writers to use other values than the default.

* avutil/{color_utils, csp}: merge color_utils into csp and expose APILeo Izen2023-02-09
| | | | | | | | | | | | | | | | | | | | | | | | libavutil/color_utils contains some avpriv_ symbols that map enum AVTransferCharacteristic values to gamma-curve approximations and to the actual transfer functions to invert them (i.e. -> linear). There's two issues with this: (1) avpriv is evil and should be avoided whenever possible (2) libavutil/csp.h exposes a public API for handling color that already handles primaries and matricies I don't see any reason this API has to be private, so this commit takes the functionality from avutil/color_utils and merges it into avutil/csp with an exposed av_ API rather than the previous avpriv_ API. Every reference to the previous API has been updated to point to the new one. color_utils.h has been deleted as well. This should not break any applications as it only contained avpriv_ symbols in the first place, so nothing in that header could be referenced by other applications.

* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-09
| | | | | | | | | | | | | | This commit does for AVOutputFormat what commit 20f972701806be20a77f808db332d9489343bb78 did for AVCodec: It adds a new type FFOutputFormat, moves all the internals of AVOutputFormat to it and adds a now reduced AVOutputFormat as first member. This does not affect/improve extensibility of both public or private fields for muxers (it is still a mess due to lavd).

* mov: Reduce the verbosity of the warning about fragmented MP4 vs advanced ↵Martin Storsjö2023-01-31
| | | | | | | | | | | | | | | | | | | | | edit lists Only warn if the advanced_editlist option is enabled (it is enabled by default though) so we don't print one warning for each track, and demote the warning to AV_LOG_LEVEL_VERBOSE; this message does get generated whenever parsing a fragmented MP4 file, regardless of whether the file actually uses multiple edits or not. Later when parsing the mov structures, the demuxer does warn if the file did contain multiple edits which would require the advanced_editlist option enabled for decoding correctly. Adjust the warning message for the case when the file seemed like it actually would have needed handling of advanced edit lists, to reflect the fact that it doesn't help to try set the option as it has been automatically disabled.

* avformat/movenc: Add loop parameter to animated AVIFVignesh Venkatasubramanian2023-01-13
| | | | | | | | | | | | | | | | | | | | | | | The HEIF specification permits specifying the looping behavior of animated sequences by using the EditList (elst) box. The track duration will be set to the total duration of all the loops (or infinite) and the duration of a single loop will be set in the edit list box. The default behavior is to loop infinitely. Compliance verification: * This was added in libavif recently [1] and the files produced by ffmpeg after this change have EditList boxes similar to the ones produced by libavif (and avifdec is able to parse the loop count as intended). * ComplianceWarden is ok with the produced files. * Chrome is able to play back the produced files.
