* avcodec/jpegxl: add Jpeg XL image codecLeo Izen2022-04-23
| | | | | | This commit adds support to libavcodec to read encoded Jpeg XL images. Jpeg XL is intended to be an extended-life replacement to legacy mjpeg.

* avformat/mov: Add support for still image AVIF parsingVignesh Venkatasubramanian2022-04-23
| | | | | | | | | | | This patch supports AVIF still images conforming to the final specification that have exactly one item (i.e. no alpha channel). The iloc box is parsed and the mov index populated. Partially fixes #7621. Signed-off-by: Vignesh Venkatasubramanian <vigneshv@google.com> Signed-off-by: Gyan Doshi <ffmpeg@gyani.pro>

* avformat/mov: fix timecode with high frame rate contentMarton Balint2022-04-22
| | | | | | | | | | | | | | | | | | | | 60 fps content have "Number of Frames" set to 30 in the tmcd atom, but the frame duration / timescale reflects the original video frame rate. Therefore we multiply the frame count with the quotient of the rounded timecode frame rate and the "Number of Frames" per second to get a frame count in the original (higher) frame rate. Note that the frames part in the timecode will be in high frame rate which will make the timecode different to e.g. MediaInfo which seems to show the 30 fps timecode even for 120 fps content. Regression since 428b4aacb1a91a267650de644519882a5f700388. Fixes ticket #9710. Fixes ticket #9492. Signed-off-by: Marton Balint <cus@passwd.hu>

* avutil/cpu: #define _GNU_SOURCE before including any standard headersMarton Balint2022-04-22

* tests/Makefile: Add auxiliary functions for transcode and stream_remuxAndreas Rheinhardt2022-04-14
| | | | | | | | | | | | | | | | | Tests using the transcode and stream_remux functions have some common requirements (namely the file and pipe protocols as well as the framecrc muxer) and also other commonalities: The create a file and read it immediately afterwards, so that they typically rely on a corresponding muxer+demuxer pair which typically shares the same name; for transcode (if it does not use stream copy) the same is true for encoders and decoders. This means that using special Makefile-functions instead of the general ALLYES is worthwhile. This commit adds such functions. These functions allow to add arbitrary CONFIG-checks on top of the aforementioned ones in order to satisfy special needs (for e.g. parsers, filters) that several intended users have.

* avcodec/mjpegenc: Don't unnecessarily grow bufferAndreas Rheinhardt2022-04-14

* avcodec/mpegvideo_enc: Fix unnecessary linear growth of bufferAndreas Rheinhardt2022-04-14
| | | | | | | | | | | If one encodes MJPEG with a single slice and uses input with AV_FRAME_DATA_ICC_PROFILE side data, the current allocation code in ff_mpv_encode_picture() will always increase the size of the temporary buffer used for allocating packets by the size needed for to write the ICC chunk even when the current buffer is actually large enough.
