* avformat/matroskaenc: Add const where appropriateAndreas Rheinhardt2023-08-101-4/+5
| | | | | | Also move getting the DOVI side data immediately before its use. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/dovi_isom: Don't use AVFormatContext* for logctxAndreas Rheinhardt2023-08-102-8/+11
| | | | | | | | Pass it as void* instead. While just at it, also constify the pointee of AVDOVIDecoderConfigurationRecord* in ff_isom_put_dvcc_dvvc(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/matroskaenc: Avoid allocations when writing Dynamic HDR10+Andreas Rheinhardt2023-08-101-19/+7

| | | | | | Improves readability; also split overlong lines. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/matroskaenc: Use proper AVIOContextAndreas Rheinhardt2023-08-101-1/+1
| | | | | | | | These two AVIOContexts currently coincide, but this is not guaranteed to remain so (in fact, I have plans to write each TrackEntry into its own AVIOContext). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/matroskaenc: Remove unnecessary checkAndreas Rheinhardt2023-08-101-2/+2
| | | | | | | It is only WebVTT which is special in WebM; hypothetical future subtitle codecs in WebM will presumably use the ordinary code. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/matroskaenc: Don't pretend to be able to mux RV30Andreas Rheinhardt2023-08-101-7/+3
| | | | | | | | | | | | | The demuxer uses a extradata offset of 26, so we would need to recreate the missing 26 bytes somehow in the muxer, but we just don't. Remuxed files (like real/rv30.rm from the FATE-suite) don't work due to missing extradata. (The extradata offset also applies to RV40 and the extradata is indeed lost upon remuxing, yet remuxing real/spygames-2MB.rmvb works; our RV40 decoder does not use extradata at all.)

* avformat/matroskaenc: Don't pretend to support unsupported codecsAndreas Rheinhardt2023-08-101-4/+0
| | | | | | | | | | | RV10 and RV20 are unsupported because creating the correct CodecPrivate is unsupported (the demuxer uses a codecpriv_offset of 26, so one would need to recreate the missing 26 bytes); COOK and SIPR are unsupported, because Matroska uses a packetization mode that is different from what FFmpeg uses in its packets (see matroska_parse_rm_audio() in the demuxer).

* avformat/matroskaenc: Don't reserve unnecessarily many EBML elementsAndreas Rheinhardt2023-08-101-1/+1
| | | | | | | | | bda44f0f39e8ee646e54f15989d7845f4bf58d26 added code that potentially added another BlockMore master and BlockAdditional data as well as BlockAddID number, yet it bumped the number of EBML elements by four instead of only three. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/matroskaenc: Support rotationsAndreas Rheinhardt2023-08-101-17/+83
| | | | | | | | | | | | | | | | | Matroska supports orthogonal transformations (both pure rotations as well as reflections) via its 3D-projection elements, namely ProjectionPoseYaw (for a horizontal reflection) as well as ProjectionPoseRoll (for rotations). This commit adds support for this. Support for this in the demuxer has been added in 937bb6bbc1e8654633737e69e403e95a37113058 and the sample used in the matroska-dovi-write-config8 FATE-test includes a displaymatrix indicating a rotation which is now properly written and read, thereby providing coverage for the relevant code in the muxer as well as the demuxer.

* avformat/sbgdec: Use avio_read_to_bprint() where appropriateAndreas Rheinhardt2023-08-091-38/+25
| | | | | | | | | | | Note: There is a slight difference in the handling of the max_file_size option: The earlier code used it to mean to limit the size of the buffer to allocate; the new code treats it more literally as maximum size to read from the input.

* avformat/rawdec: Don't include avcodec.hAndreas Rheinhardt2023-08-051-2/+0

* avformat/internal: Use forward declaration for AVCodecDescriptorAndreas Rheinhardt2023-08-052-2/+2
| | | | | | | | | | | This avoids including lavc/codec_desc.h everywhere and thereby forces users to include it directly instead of lazily and potentially unknowingly relying on indirect inclusions. Also add the proper inclusion to libavformat/demux.c, one of the two files that actually use the new field. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/flvdec: handle exheader fourcc correctly in metadataMarton Balint2023-08-031-45/+29

* avformat/hls_sample_encryption: Always free AC3HeaderInfo on errorAndreas Rheinhardt2023-08-021-4/+2
| | | | | | | | | | | | The code currently presumes that a return value of AVERROR(ENOMEM) implies that ac3hdr could not be allocated, so it need not be freed. Yet any avpriv_ac3_parse_header() might allocate more than the AC3HeaderInfo internally (it doesn't currently), so simply free it unconditionally. Fixes Coverity issues #1492870 and #1492868.

* libavformat: fix incorrect handling of incomplete AVBPrint.Reimar Döffinger2023-07-2910-15/+56
| | | | | | | | | | | | | Change some internal APIs a bit to make it harder to make such mistakes. In particular, have the read chunk functions return an error when the result is incomplete. This might be less flexible, but since there has been no use-case for that so far, avoiding coding mistakes seems better. Add a function to queue a AVBPrint directly (ff_subtitles_queue_insert_bprint). Also fixes a leak in lrcdec when ff_subtitles_queue_insert fails.

* avformat/flvdec: fix size desync when reading timestamp offsetsHendrik Leppkes2023-07-251-2/+1
| | | | | | | | | The size offset was previously being accounted for in flv_set_video_codec for h264 and mpeg4, instead of being directly accounted for in the spot where its read, which desynced on HEVC streams. For clarity, move the size offset directly to the parsing, similar to how its done for all other header fields.

| | | | | | | | | | | | I cannot find the spec, but according to the original commit d4fdba0df71, it's CAVS. e571305a714 changed it to AVS by accident. Ten years on, nothing happened. We still have the sample [1], however, since there is no cavs_mp4tofoobar bsf, the cavs decoder doesn't work. I don't know if there is any use case.

* avformat/evcdec: Avoid nonsense castsAndreas Rheinhardt2023-07-071-3/+3
| | | | | | | | | | | | | For uint8_t buf[EVC_NALU_LENGTH_PREFIX_SIZE], &buf still points to the beginning of buf, but it is of type "pointer to array of EVC_NALU_LENGTH_PREFIX_SIZE uint8_t" (i.e. pointer arithmetic would operate on blocks of size EVC_NALU_LENGTH_PREFIX_SIZE). This is of course a different type than uint8_t*, which is why there have been casts in evc_read_packet(). But these are unnecessary if one justs removes the unnecessary address-of operator.
