Subject: [FFmpeg-devel] [PATCH v3 0/1] avcodec/libjxlenc: Add libjxl_anim encoder
Date: Thu, 21 Dec 2023 21:22:11 +0000
Message-ID: <G7yNBJOt-dBR1dKEAMF3TfaKurGRysRcbb0Lydb4GVw7Mw-07QnuvQbqxSHvQD07EV5sDcROazpvlodWSllqSAG-X6xk5mdKvbnilS2gSBA=@protonmail.com> (raw)
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)
