Wishlist: Support decoding non-FFV1

[pjotrek-b]

This has low-to-no priority at all, but might be interesting for some:

I just tested a codec roundtrip:

• gbrp10le DPX source
• RAWcooked to FFV1/MKV
• ffmpeg to uncompressed (R210) (with "-map 0" to keep the reversibility data streams)

Decompression back to original DPX files required to convert uncompressed back to FFV1.

Would it be possible to decode non-FFV1 directly, too (e.g. whatever ffmpeg supports)? This would allow future codec format migrations, while keeping the DPX-reversibility :sunglasses: :smile: (Just curious, if you have time and interest to answer this :wink:)

There is lot of development to do for that:

• Implement FFmpeg decoder library in RAWcooked (currently it is internal)
• Map each FFmpeg "pix_fmt"to DPX format (note: double RAM usage, from bitstream to FFmpeg "pix_fmt", then FFmpeg "pix_fmt" to DPX, with e.g. 4K/8K it is a speed blocker due to RAM bandwidth)

Doable but sponsor needed ;-)

Thanks for the explanation! :smile:
