[FFmpeg-user] How to use deinterlace_qsv filter with ffmpeg command on Windows

[redsks]

Hi Moritz Barsnick,

Thanks.

Sorry for that the information I provided has something wrong, may be I lost
something, please  regardless of it, the followings are what I want to say:

    I can not run "deinterlace_qsv" filter on both linux and windows. 

My linux OS is "CentOS Linux release 7.2.1511 (Core) " with Intel Media SDK
installed which can run intel modules.

I have comiled the ffmpeg with libmfx.lib  and the filters include the
"deinterlace_qsv":

* ~]# ./ffmpeg -filters | grep qsv

Then I used the command line:

*./ffmpeg -qsv_device /dev/dri/renderD128   -hwaccel qsv
-hwaccel_output_format qsv  -i basketball.ts -map 0:v:0 -map 0:a:0    -vf

-strict -2 -acodec aac -ab 64K -ar 44100 -ac 2  -vsync -1 -f flv  -y
test.flv*


It output the following information:

 * libpostproc    54.  5.100 / 54.  5.100

Conversion failed!*

If I remove "-vf 'deinterlace_qsv' ", it can work. So if I want to do
de-interlace with "deinterlace_qsv" filter,  What is the correct command for
it? Do I lose something?

Thanks.
