New VVC codec issues

FFmpeg-users mailing list
Hi !
I have some VVC (versatile video codec) files and wanted to run some tests to see how much computational power is needed to decode them. The FFmpeg does not recognize the stream, even when i use the copy_unknown command it does nothing and also asks for an output container format ( i want the raw stream on a .bin file). The issue is discussed here :
r/VVC - No way found to play vvc files

We can't really read your e-mail. Here's how wo see it on the list:
http://ffmpeg.org/pipermail/ffmpeg-user/2020-July/049381.html

Is it this thread?
https://www.reddit.com/r/VVC/comments/hputue/no_way_found_to_play_vvc_files/

Kindly describe your problem directly here.

Thanks,
Moritz

Ah, is VCC identical with H.266? Yet another patent encumbered next
generation codec with the same issues as H.265, trying to compete with
VP10 and AV1 and AV2.

ffmpeg doesn't have support for that yet. Patch welcome. Perhaps if the
MPEG consortium could provide a free, open reference decoder
implementation? Just dreaming...

Cheers,
Moritz

 From what I've seen, it is functionally an expansion on 265 in the same way that 265 was an expansion on 264.
And yes, the same political problems attend it that also attended 265, and no real effort has been made to solve those problems.
As such it's probably irrelevant how good it is because no bugger's going to use it anyway.

My bad, that Reddit does point to the Fraunhofer implementation, which
is under a BSD license (but still would need to be evaluated whether it
is "free" in ffmpeg's terms).

Anyway, still no support in ffmpeg yet. ;-) I'll have a look whether I
can manage to use the Fraunhofer tools on those files, and whether I
can convice ffmpeg to export the raw stream:

Probably with "-map 0:s -c:s copy -f rawvideo output.bin", assuming
it's recognized as a data stream(?). I will try myself. Please always
show us the command line you tried and its complete uncut console
output.
