Comment (by Vignesh Venkatasubramanian):

 Hi Balling,

 > a) the chroma siting support for top left of 420 right here:
 ​https://github.com/AOMediaCodec/av1-avif/issues/88

 What exactly do you need ffmpeg to do for this issue? I am not sure i
 understand the requirement.

 > b) avif MIME

 Same here. What mime type support do you want in ffmpeg?

 > c) the patch for for item_count merged
 > d) alpha patch support merged

 These two are now merged. I am working on some follow-up patches for still
 image alpha and grid image support.

 > e) HEIC container patches reworked and applied (see HEIF ticket) and
 HEIF integrated too, since it is so close

 I am not very familiar with the HEIC features. I will try to look into it.

 > f) maybe cpu-used set to 0 and of course defaulting for lossless (crf
 0).

 You can pass these options now to libaom (or other av1 encoders availabvle
 on ffmpeg) using the command line options.
