#1498 implements necessary header changes, but we need to implement disable_frame_end_update_cdf before we can enable the reduced header in the Sequence constructor.

I've just enabled still_picture in libavif and the encoded picture then can't be decoded by dav1d.

From AV1 Image File Format (AVIF), 2.1 AV1 Image Item:

  • The AV1 Image Item Data should have its still_picture flag set to 1.
  • The AV1 Image Item Data should have its reduced_still_picture_header flag set to 1.

This issue impacts producing typical sequences for libavif. Emphasis added above.

We have added support for importing and exporting AVIF files in darktable which will be released with version 3.0.1. It would be great to have this fixed in rav1e soon.

@cryptomilk Sorry for the delay in addressing this, I implemented still picture mode a few months back and it seems like other changes in the encoder broke it since then. I will add some tests to avoid future regressions and try to solve the issues found (#2112 and #2113) in a timely manner. In the meantime, #2108 should solve errors when encoding a single image frame, which I think should cover your use case.

Awesome thanks. I'm travelling this week and will test it next week once i'm back.

Upon further testing there's some extra work to do before the reduced still picture header is supported, hopefully soon. #2108 fixes the still picture mode for any number of frames, without the reduced still picture header (which should be legal AVIF, but not recommended).

@rzumer Thank you very much for fixing this! Now there is one bug/feature left for AVIF and that's lossless support.

@cryptomilk I can't promise that support will be added soon, but I have tagged the corresponding issue (#151) for tracking.
