* avcodec/h264_redundant_pps_bsf: Support multiple input PPSAndreas Rheinhardt2021-12-03
| | | | | | | | | | | | | | | | Up until now, the h264_redundant_pps_bsf stored the initial value of pic_init_qp_minus26 of the most recently encountered PPS; it also modified the slices based upon to assumption that the most recent PPS is the PPS the slice belongs to. Yet this assumption is flawed, as there can be several PPS with different IDs that are visible at any given time. If these have different pic_init_qp_minus26 values, the output can be invalid. Fix this by directly using the pic_init_qp_minus26 value of the input PPS. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/movtextenc: Fix encoding of subtitles with multiple rectsAndreas Rheinhardt2021-12-02
| | | | | | | | | | | | | | | | | | | | | | | | The format of a mov_text (3GPP Timed Text) sample is: uint16_t text_length; uint8_t text[text_length]; TextSampleModifierBox text_modifier; Yet in case our encoder receives an AVSubtitle with multiple ASS AVSubtitleRects, it creates something like this: uint16_t text_length; uint8_t text[text_length_1]; TextSampleModifierBox text_modifier_1; uint8_t text[text_length_2]; TextSampleModifierBox text_modifier_2; ... where text_length is the sum of all the text_length_*. This commit fixes this by writing the TextSampleModifierBoxes only after all the rects have been written.

* avcodec/qsvenc: Fix leak of A53 dataAndreas Rheinhardt2021-11-30

* avcodec/qsvenc: Fix leak and crash when encoding H.264 due to A53_CCAndreas Rheinhardt2021-11-30
| | | | | | | | | | | | | | | | | | | | | Since commit 3bbe0c210b05fc6fbd7b1d4bbd8479db7f2cf957, the Payloads array of every QSVFrame leaks as soon as the frame is reused; the leak is small and not very noticeable, but if there is an attempt to use said array the ensuing crash is much more noticeable. This happens when encoding H.264 with A53 CC side data. Furthermore, if said array can not be allocated at all, an AVFrame leaks. Fix all of this by not allocating the array separately at all; put it in QSVFrame instead and restore the Payloads array upon reusing the frame. Finally, use av_freep() instead of av_free() to free the payload entries. Reviewed-by: Xiang, Haihao <haihao.xiang@intel.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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.

* 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.
