If you take a look at info it says qsv vpp pass through mode
so it should convert to P010le pix_fmt to encode 8 bit AVC to 10 bit HEVC

Could you please highlight what is your expection and what is the real output?

comment:2 by thx4ever, 2 years ago

I expect that it will convert the pix_fmt 8 bit to 10 bit using VPP to be able to use HEVC 10bit encoding, but right now the real output are garbage like i have added in attachment sample_HEVC, what it needs to do its convert the sample_AVC that are 8bit to 10 bit using Intel QSV VPP

Haven't tested it on windows with qsv HEVC software encoding. But I can reproduce your issue on Linux with HEVC HW encoding:

ffmpeg -hwaccel qsv -v verbose -c:v h264_qsv -i tikect_8065/sample_AVC.264 -vf vpp_qsv=format=p010le -c:v hevc_qsv -load_plugin hevc_hw -profile:v main10 -preset:v veryslow -g 240 -refs:v 6 -bf:v 3 -flags -cgop -gpb 0 -q:v 18 -vframes 5 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -bsf:v hevc_metadata=colour_primaries=1:transfer_characteristics=1:matrix_coefficients=1 sample_HEVC.hevc

Transcoding failed with "qsv vpp pass through mode" message.

I still can reproduce same issue on Windows with your patch, my command line options used

It is not same issue right now. The "pass through mode" message goes away, and you changed your command line: add scaling and BRC modes: CQP->AVBR

Some questions:

  1. Have you tried HEVC HW encoder,what is the result?
  2. Why you change BRC mode from CQP to AVBR and add scaling? Dose CQP mode can work?
  3. Have you tried HEVC SW encoder with MSDK sample encoder?
  4. Try to figure out it is an qsv vpp issue or encoder issue. You can disable encoder and check the output of vpp.

1 - Yes i have tried HEVC HW Encoder and it Works but when try software encoder the final result are garbage of colors, it seems something is wrong with ffmpeg
2- Sorry for that but doenst matter what BRC i use, CQP-AVB-VBR on HW it Works but software is garbage, can u address this bug to ffmpeg developers to fix this issue? This Works on sample_multi_transcode on Windows 10 Pro x64 with git Media SDK
3- Yes sample encoder Works but i use alot ffmpeg right now
4- OK i will try and send feedback to you

comment:8 by thx4ever, 2 years ago

I have checked it Works but when i add -pix_fmt p010le the final result is incorrect, i think the problem are in ffmpeg color conversion from 8bit to 10bit, can u look for me this problem?

Could you please share your sample encoder and sample multi transcode command line?

I checked MediaServerStudioProfessional2017 release guide, it is said that:

MAIN10 profile encoding/decoding and range extensions profile encoding can
be done only with system memory at input and output on linux (SDK/driver
limitation for video memory frames allocation)

Thus means probally you should remove the "-hwaccel qsv" to make it is working in sytstem memory:

Probably you have two options:

  1. remove "-hwaccel qsv" and add "-filter_hw_device".
  2. keep "-hwaccel qsv " and use "hwdownload" See examples of http://trac.ffmpeg.org/wiki/Hardware/QuickSync

I'm using latest Intel Media SDK from GitHub

I don't think github MSDK can support Windows. Is there anything wrong?

The only way to get ffmpeg working are this command options but the final Picture is garbage

ffmpeg -v verbose -hide_banner -hwaccel qsv -c:v h264_qsv -i "sample.264" -vf vpp_qsv=format=p010le,hwdownload,format=p010le -c:v hevc_qsv -load_plugin hevc_sw -profile:v main10 -preset:v veryfast C:\Users\thx4ever\Desktop\sample.hevc

Yes i can use GitHub MSDK, that is what i currently use

https://patchwork.ffmpeg.org/patch/14522/ has been merged since HEVC HW encoding can work now.
For HEVC SW encoding problem,probally you can file an issue on MSDK github too (but I can't find HEVC SW encoding can be supported by https://github.com/Intel-Media-SDK/MediaSDK).

Note: See TracTickets for help on using tickets.
