* ffmpeg: remove ffmpeg_videotoolboxrcombs2021-11-28
| | | | | | This was almost completely redundant. The only functionality that's no longer available after this removal is the videotoolbox_pixfmt arg, which has been obsolete for several years.
* avcodec/vqavideo: Remove dead codeAndreas Rheinhardt2021-11-28

* avcodec/mobiclip: Rewrite code to make it clearerAndreas Rheinhardt2021-11-28
| | | | | | | | | | In order to know that the earlier code did not use uninitialized values one needs to know that the lowest four bits of each used value of pframe_block4x4_coefficients_tab do not vanish identically. E.g. Coverity did not get this and warned about it in ticket #1466632. Fix this by slightly rewriting the code. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avfilter/vf_paletteuse: Add missing parenthesesAndreas Rheinhardt2021-11-27
| | | | | | | | Fixes a mistake in dea673d0d548c864ec85f9260d8900d944ef7a2a. GCC emitted a -Wint-in-bool-context warning because of that. Reviewed-by: Soft Works <softworkz@hotmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/img2dec: probe JFIF/Exif headerAlex Xu (Hello71)2021-11-27
| | | | | | | | | | | | | | | | | Due to reasons, mpv doesn't pass filename when probing. mpv also sets default probescore threshold to 26. Since the current jpeg_probe implementation returns 25 until EOI, it means that the whole image needs to be probed to succeed. Worse, the whole image is not passed at once; increasingly large buffers are tried before that. Adding it up together, if many demuxers are enabled, moderately large JPEG files (few MB) can take several seconds to open, despite taking less than 1 second to actually decode. Therefore, adjust the heuristic to be more optimistic if proper JFIF or Exif segments are found. While not strictly required, the vast majority of JPEG-ish files have one or the other or both.

* avcodec/mjpeg_parser: skip markers after EOI, not by sizeAlex Xu (Hello71)2021-11-27
| | | | | | | | | | | | | The check for m->size >= 0xF000 is intended to avoid skipping too much garbage data between JPEG frames in test_roman (thus missing next SOI), but it erroneously also skips valid markers between SOI and SOS. Instead of this, we should simply skip parsing markers other than SOI after EOI. That way, we will not accidentally skip over SOI due to some garbage between frames. There is still a small risk of encountering FFD8 in the garbage data, but the chance of this is fairly low.

| | | | | | | | | | For most check_bitstream() functions this just avoids having to dereference s->streams[pkt->stream_index] themselves; but for meta-muxers it will allow to forward the packet to stream with a different stream_index (belonging to a different AVFormatContext) without using a spare packet.

* fftools/ffmpeg: Take type limitations of AVFifo API into accountAndreas Rheinhardt2021-11-26
| | | | | | | | | | | | The types used by the AVFifo API are inconsistent: av_fifo_(space|size)() returns an int; av_fifo_alloc() takes an unsigned, other parts use size_t. This commit therefore ensures that the size of the muxing_queue FIFO never exceeds INT_MAX. While just at it, also make sure not to call av_fifo_size() unnecessarily often.

* Revert "Disable warnings for casting pointers to integers, there is nothing ↵Andreas Rheinhardt2021-11-26
| | | | | | | | | | | | | wrong with that." This reverts commit 5258f64a14713499cf84840b3ab3a1ee7cdcaeb8. The premise of said commit (that conversions from pointer to int are ok) is wrong: C99/C11 6.3.2.3 5: "Any pointer type may be converted to an integer type. [...] If the result cannot be represented in the integer type, the behavior is undefined." (C90 6.3.4 contains a similar restriction.) So don't disable -Wpointer-to-int-cast.

* avcodec/h263: Fix global-buffer-overflow with noout flag2 setAndreas Rheinhardt2021-11-26
| | | | | | | | | | | | h263_get_motion_length() forgot to take an absolute value; as a consequence, a negative index was used to access an array. This leads to potential crashes, but mostly it just accesses what is to the left of ff_mvtab (unless one uses ASAN), thereby defeating the purpose of the AV_CODEC_FLAG2_NO_OUTPUT because the sizes of the returned packets differ from the sizes the encoder would actually have produced.

* avformat/mov: make STTS duration unsigned intGyan Doshi2021-11-22
| | | | | | | | | | As per 8.6.1.2.2 of ISO/IEC 14496-12:2015(E), STTS sample offsets are to be always stored as uint32_t. So far, they have been signed ints which led to desync in files with very large offsets. The MOVStts struct was used to store CTTS offsets as well. These can be negative in version 1. So a new struct MOVCtts was created and all declarations for CTTS usage changed to MOVCtts.
