vaapi deinterlacing with frame rate doubling does not work, only 25 fps at the output.

If you want field-rate output rather than frame-rate output then maybe it would help to provide the option selecting that?

-vf vaapi_deinterlace=rate=field

[Igor]

Thank you for answering me.
Yes, of course I tried option "rate=field":
ffmpeg -y -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD129 -i ~/Видео/2011.05.01_11-11-53.m2ts -vf deinterlace_vaapi=rate=field -c:v h264_vaapi -bf 2 output.mp4
But I get this message:

[Parsed_deinterlace_vaapi_0 @ 0x394e3c71c0] Option 'rate' not found
[AVFilterGraph @ 0x394e3c5f60] Error initializing filter 'deinterlace_vaapi' with args 'rate=field'
Error reinitializing filters!
Failed to inject frame into filter network: Option not found

Oh right, it was added after 3.3 branched. Try a later version.
