Comment:

 4:2:2 profile for mpeg2 is not supported by driver(iHD).

 $ mediainfo xdcam8mp2-1s_small.ts
 Video
 ID : 256 (0x100)
 Menu ID : 1 (0x1)
 Format : MPEG Video
 Format version : Version 2
 Format profile : 4:2:2 at Main



 $ vainfo

 VAProfileMPEG2Simple : VAEntrypointVLD
 VAProfileMPEG2Simple : VAEntrypointEncSlice
 VAProfileMPEG2Main : VAEntrypointVLD
 VAProfileMPEG2Main : VAEntrypointEncSlice
 VAProfileH264Main : VAEntrypointVLD

 Moreover, ffmpeg only enables hardware decode support for mpeg2 420 in
 mpeg12dec.c
 4:2:2 hardware accelerate is not supported.
 {{{

     AV_PIX_FMT_CUDA,
 #endif

 };
 }}}



 So this issue is invalid and could be closed.
