View Full Version : Looking for a x266 (VVC) sample file

I've searched the web already with no success. I'm looking for a sample video file with a VVC video stream in MKV or MP4 container. I also tried already to encode my own one, but failed.
Can somebody guide me to a sample file?

Oh, I'm not sure?
It has .vcc, & it has .mp4, but I guess it is not .vcc in a .mp4?

(I have no idea what vcc is ;-).)


Someone who frequents these parts posted, VVC (H.266) needs support in demultiplexers, primarily MP4 (https://code.videolan.org/videolan/vlc/-/issues/27055), that looks to have a sample in a .mp4.


Format : vvc1
Codec ID : vvc1

VVC file can be added into MP4 contaner, but not MKV at the moment.

To encode:
VVenC encoder and mp4box: https://drive.google.com/drive/folders/1D_-QdcCgqrHG8I1h09wst1xP27PkkfkS?usp=share_link

ffmpeg -i input.mkv -pix_fmt yuv420p10le -strict -1 -f yuv4mpegpipe - | vvencapp -i - --y4m --preset fast --qp 24 --qpa 1 --threads 16 -o "out.266"

then put into mp4

mp4box -add "video.266" -add "audio.m4a" -new "video.mp4"

That's because you weren't looking for it right.

You should be looking for H.266 sample files not x266 sample files. H.266/VVC is a codec, not x266 which is an encoder.

Also, the only ones who have x266 encoded files are the Multicoreware guys at this stage and they made some tests and comparison for x266 v0.x which isn't public yet as it's still missing features and it's being worked on. They're currently working on v1.0. It's slightly worse than VVEnc in terms of encoding efficiency at this very early non public stage, but it's much faster thanks to manually written assemblies/intrinsics.

Thanks, now I do have some samples.

...

Ah, this also worked. I already tried it with VVenC encoder itself, but it only accepts yuv input. So I've tried to convert an mkv sample to yuv and then converted it with VVenC encoder. But this did not work. Your one line solution then did the trick. And the mp4box was also helpful.
