[FFmpeg-devel] [PATCH v3 0/1] avcodec/libjxlenc: Add libjxl_anim encoder

[FFmpeg-devel] [PATCH v3 0/1] avcodec/libjxlenc: Add libjxl_anim encoder

[Zsolt Vadász via ffmpeg-devel]

This patchset adds support for encoding animated JPEG XL images via a
new encoder (libjxl_anim). When using the encoder, the output format
needs to be set to raw video, as shown below:
`ffmpeg -i sample.gif -c:v libjxl_anim -f rawvideo out.jxl`

V3 changes:
- Renamed encoder to libjxl_anim for consistency
- PTS is now calculated
- JxlFrameHeader.duration is calculated from PTS instead of relying on
  AVFrame->duration being set
- This version also does not rely on AVCodecContext->frame_num either
- Disabled the container container format (JxlEncoderUseContainer)
