Corrupted HEVC encoded files on Tiger Lake

[angryziber]

Ubuntu 21.04
intel-media-va-driver-non-free 21.1.1+ds1-1
ffmpeg 7:4.3.2-0+deb11u1ubuntu1
CPU: 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz
Laptop: Asus Zenbook UX393E

When encoding a video to HEVC with ffmpeg & vaapi, no errors are given, but the output is corrupted (screenshot below).
VP9 and H264 files are encoded fine.

ffmpeg -hide_banner -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -i $FILE -c:v hevc_vaapi -qp 27 -rc_mode ICQ -c:a copy $OUT

output:

@fulinjie built latest ffmpeg master, got same corruption with hevc_vaapi encode on intel TGL

[Xiaogangli-intel]

Thank you @rmkimathi, working on this issue, will update it once we have some progress.

[lobomfz]

Is there any progress on this? i haven't been able to encode hevc for half a year

Hi,
I have the very same problem on i9-11900T
with UHD 750.

The setup I have is:
Open SUSE Tumbleweed 20211101 with ffmpeg 4.4.1
Kernel 5.14.14-1 64 bit
Mesa Intel Graphics

I am not able to encode with ffmpeg using va-api
ffmpeg -y -vaapi_device /dev/dri/renderD128 -i input.ts -vf 'format=nv12,hwupload' -c:v hevc_vaapi -b:v 6M -c:a copy out.mkv

@lobomfz
Did you find a solution?

Hi @Xiaogangli-intel @XinfengZhang this may be caused by leak of VAConfigAttribEncHEVCFeatures&VAConfigAttribEncHEVCBlockSizes attrib report on TGL+ in media-driver. Previously Mark submitted a patch #866 which based on legacy interface. It need port to lastest libva interface. And I am not sure if Mark's patch is correct, in my understanding, TGL+ attrib should be sperated with common platform. So could you help to submit a new one ASAP? Since it blocks hevc encode on TGL+ by using upstream ffmpeg-vaapi. Only after the attrib report patch merged in media-driver, we can verify and submit ffmpeg-vaapi patch.
Also CC @lwan108 who reported some incorrect setting on Mark's patch.

@angryziber @lobomfz @georgnistor @rmkimathi, here is a workarround patch for ffmpeg-vaapi, which may fix your issue temporarily:

[rmkimathi]

Thank you @feiwan1

Workaround patch for ffmpeg fixes hevc_vaapi encode on TGL Xe Graphics.

[xhaihao]

@feiwan1 My understanding is that the added interfaces should be applied to TGL+ only, the legacy code works on ICL.

[feiwan1]

Thanks @xhaihao for reminder. Current code works on ICL indeed. Just need to update TGL+'s code only. And corrected my previous comment.

#1121

[flyingfalling]

I know this issue was closed, but I am still seeing this exact same behavior (ubuntu 22.04.1, ffmpeg 4.4.2).

intel core i5-1240P (12th gen)
VA-API 1.14 (libva 2.12.0)
iHD driver 22.3.1

I see the pull happened in intel media driver 22.5.4? So do I understand correctly that I will need a newer version than that to have this issue fixed?

[nyanmisaka]

@flyingfalling The ffmpeg fix exists in n5.1+ versions. Also make sure the ffmpeg is build against libva 2.12+.
