Strange colors when trying to encode 4k with VP9

[rockerovo]

I'm trying to encode 4k yuv video with webmproject VP9 I m using Linux Kubuntu 18.04 my command :

./vpxenc --codec=vp9  --profile=0  --fps=50000/1001 --static-thresh=0 --drop-frame=0 --good --auto-alt-ref=1  --kf-min-dist=50 --kf-max-dist=50 --min-q=32 --max-q=32 --max-intra-rate=50 -w 3840 -h 2160 --limit=1 --i420 /home/siraj/Desktop/Project/Samples/Jockey_3840x2160_120fps_420_10bit_YUV.yuv -o siraj.webm

when trying to open webm in chrome, I got a Strange color https://i.stack.imgur.com/EYdJS.jpg

I guess vpxenc does not understand 10-bit-per-component YUV formats.

[gdx]

It only happens in chrome? it can be only a chrome because it looks like a video renderer issue, also can yo post a sample file?

I guess vpxenc does not understand 10-bit-per-component YUV formats.

I think I found the problem < I'm using profile 0, I need to switch to profile 2 and enable --enable-vp9-highbitdepth

chrome, firefox,
and then i decode it to yuv and play it with some yuv players, all the same

I think the problem is with the profile 0 I need to switch it to 2 and enable --enable-vp9-highbitdepth

[rockerovo]

I did

siraj@RouterX:~/Desktop/Project/VP9/libvpx-master$ ./configure --enable-vp9-highbitdepth

can you post sample of your converted video?

Its beacuse you don't specify the input bitdepth, vpxenc don't support converting 10 to 8 bits then you need to use profile 2 and specify both the input bitdepth and the video bitdepth:

vpxenc --codec=vp9  --profile=2  --fps=50000/1001 --static-thresh=0 --drop-frame=0 --good --auto-alt-ref=1  --kf-min-dist=50 --kf-max-dist=50 --min-q=32 --max-q=32 --max-intra-rate=50 -w 3840 -h 2160 --limit=1 --i420 --input-bit-depth=10 --bit-depth=10 Jockey_3840x2160_120fps_420_10bit_YUV.yuv -o siraj.webm

if you want to do it 8 bits you can pipe it through ffmpeg:

ffmpeg -f rawvideo -vcodec rawvideo -s 3840x2160 -r 50000/1001 -pix_fmt yuv420p10le -i "Jockey_3840x2160_120fps_420_10bit_YUV.yuv" -vframes 1 -pix_fmt yuv420p -strict -1 -f yuv4mpegpipe -an -sn - | vpxenc --codec=vp9  --profile=0  --static-thresh=0 --drop-frame=0 --good --auto-alt-ref=1  --kf-min-dist=50 --kf-max-dist=50 --max-intra-rate=50 --passes=1 --end-usage=q --cq-level=32 -o siraj.webm -

But if you uses ffmpeg you have to do the 2 passes manually if you want then. Also this "--min-q=32 --max-q=32" technically that is equivalent to "--end-usage=q --cq-level=32"

[fornit]

Hm,

to be honest, your encoding string looks a bit like an encoding for VP8.

Google has provided some infos how to deal with VP9:
https://developers.google.com/media/vp9/

Just tried it as follows (ffmpeg version 3.4.2):
- 2pass
- crf 32
- Fixed keyframe interval of 50 (as in your encoding)
- Input frame rate 120 fps (the name of your original file suggests that)
- Output frame rate 50000/1001 (as in your encoding)
- Renamed the file to jockey.yuv and jockey.webm - gives a better overview

1st pass:

ffmpeg -f rawvideo -c:v rawvideo -s 3840x2160 -r 120 -pix_fmt yuv420p10le -i jockey.yuv -vf fps=fps=49.950 -keyint_min 50 -g 50 -pass 1 -passlogfile jockey-2160 -c:v libvpx-vp9 -threads 8 -cpu-used 4 -tile-columns 3 -frame-parallel 1 -b:v 0 -crf 32 -an -f webm -y NUL

2nd pass:

ffmpeg -f rawvideo -c:v rawvideo -s 3840x2160 -r 120 -pix_fmt yuv420p10le -i jockey.yuv -vf fps=fps=49.950 -keyint_min 50 -g 50 -pass 2 -passlogfile jockey-2160 -c:v libvpx-vp9 -threads 8 -cpu-used 3 -tile-columns 3 -frame-parallel 1 -auto-alt-ref 1 -b:v 0 -crf 32 -an -f webm -y jockey.webm

Seems to work fine. Please find the result attached.

Its beacuse you don't specify the input bitdepth, vpxenc don't support converting 10 to 8 bits then you need to use profile 2 and specify both the input bitdepth and the video bitdepth:

vpxenc --codec=vp9  --profile=2  --fps=50000/1001 --static-thresh=0 --drop-frame=0 --good --auto-alt-ref=1  --kf-min-dist=50 --kf-max-dist=50 --min-q=32 --max-q=32 --max-intra-rate=50 -w 3840 -h 2160 --limit=1 --i420 --input-bit-depth=10 --bit-depth=10 Jockey_3840x2160_120fps_420_10bit_YUV.yuv -o siraj.webm

if you want to do it 8 bits you can pipe it through ffmpeg:

ffmpeg -f rawvideo -vcodec rawvideo -s 3840x2160 -r 50000/1001 -pix_fmt yuv420p10le -i "Jockey_3840x2160_120fps_420_10bit_YUV.yuv" -vframes 1 -pix_fmt yuv420p -strict -1 -f yuv4mpegpipe -an -sn - | vpxenc --codec=vp9  --profile=0  --static-thresh=0 --drop-frame=0 --good --auto-alt-ref=1  --kf-min-dist=50 --kf-max-dist=50 --max-intra-rate=50 --passes=1 --end-usage=q --cq-level=32 -o siraj.webm -

But if you uses ffmpeg you have to do the 2 passes manually if you want then. Also this "--min-q=32 --max-q=32" technically that is equivalent to "--end-usage=q --cq-level=32"

When using the first code i got :
i cant enable the profile 2

actually, I'm working on a project about VP9,AV1,HEVC,AVC , do you think FFmpeg better that webmproject libvpx , i found the source in webmproject website

when I use the first command for pass 1 I got :

the pass 2 command works great, Thank you

but do you know how I can enable profile 2 vpxenc

[fornit]

actually, I'm working on a project about VP9,AV1,HEVC,AVC , do you think FFmpeg better that webmproject libvpx , i found the source in webmproject website

ffmpeg is something like the swiss army knife of video encoding

I don't know whats the problem, I'm using Intel® Core™ i7-3610QM ,6GB ram

There isn't a problem. The message "Output file is empty, nothing was encoded" is normal after the 1st pass. It only writes the log file in the 1st pass.

but do you know how I can enable profile 2 vpxenc

Please check if your version of ffmpeg supports 10 bit with VP9:

ffmpeg -h encoder=libvpx-vp9

At the top there is a line named "supported pixel formats". Look for: yuv420p10le -> if it's not there, then you need a more current version of ffmpeg. The newer versions have 8 bit and 10 bit support.

With 10 bit support for VP9 simply repeat the pixel format behind the input file. "Profile 2" will then be selected automatically. This makes the encoding strings looking as follows.

Yo didn't add the"-" add the end that indicates to read the pipe to the encoder.

For you question fornit had responded quite well, but in the case of av1 the av1enc is far superior as the ffmpeg integration is quite lacking for now.

Thank you! everything works like a charm, I was using the old version for FFmpeg, I followed this guide and now I'm using the latest version with 10-12 bit support
