SW Decoding -> QSVVPP -> QSV Encoding fails #19

Closed ghost closed 6 years ago

ghost commented 6 years ago

Hi,

it looks like that this version does not support the combination described in the title. Here is an output using FFmpeg:

It also fails with -hwaccel qsv

The 3.4.1 branch is not ready now (see https://github.com/Intel-FFmpeg-Plugin/Intel_FFmpeg_plugins/wiki#introduction ). Is it ok for you to use 3.3.1 branch now? I'll reply when 3.4.1 branch is ok.

"It also fails with -hwaccel qsv" It works for me by adding "-hwaccel qsv -c:v h264_qsv ": ./ffmpeg -hwaccel qsv -c:v h264_qsv -y -i /samba/anonymous/Videos/test.h264 -an -vcodec h264_qsv -preset slow -profile:v high -level:v 31 -g 72 -aspect 16/9 -look_ahead 1 -look_ahead_depth 30 -b:v 2000000 -vsync 1 -r 24.000000 -vf '[main]vpp_qsv=w=1280:h=720[out]' out.mp4

Hi,

adding "-hwaccel qsv -c:v h264_qsv" means that h264 QSV decoding is enabled. What I report, is that it won't work when h264 QSV decoding is not enabled.

Understood for the 3.4.1 branch, can you please fix this feature in it ?

THanks

@ViGill , yes, we will fix this issue of 3.4.1 branch. Thanks for reporting this issue.

Hi,

it looks fine now using:

-init_hw_device qsv=foo -filter_hw_device foo -vf format=nv12,hwupload

with latest commits!

lizhong1008 commented 6 years ago

@ViGill , great! Is it ok to close this issue now?

Yes thanks!
