dvvideo transcoding error

[moon1234]

When serviio sends a dvvideo file to ffmpeg for transcoding to mpeg2video, ffmpeg sets the output pixel format to yuv422p by default. This pixel format is unplayable on my Sony Blu-Ray player and I would guess most other devices.

If I manually set pix_fmt=yuv420p in the command line that is sent to ffmpeg I get a playable file.

Is there a way to either change serviio to include the pix_fmt=yuv420p when serving files that match dvvideo tag or some way for me to manually include this tag in the serviio profile? It would be really nice to have a way of passing custom parameters to ffmpeg via a serviio profile. Then we could at least work around issues when the do crop up.

Command line stuff and output from ffmpeg:
F:\Video\Home\1981\Joanne's.avi -y -threads 1 -copyts -c:v mpeg2video -b:v 8000k -maxrate:v 8000k -bufsize:v 8000k -r 30000/1001 -g 15 -c:a ac3 -b:a 384k -ar 48000 -ac 2 -map 0:0 -map 0:1 -sn -f mpegts C:\Windows\TEMP\Serviio\transcoding-temp-11886-10-ORIGINAL.stf

I used perl script on windows to customize ffmpeg command line for testing purpose.
