My MPEG transcoding has really bad ghosting. It happens for all transcoded files, whether SD or HD, regardless of formats and containers.

TV: Panasonic Viera TC-P55GT30
Serviio 0.6.2 on Windows 7 64-bit

Also, can someone tell me how to disable the MediaItemDAOImpl and other crap from filling up my debug log so I can find the actual problem? I'm guessing this has something to do with the ffmpeg command line parameters, because when I manually use ffmpeg to convert the file into something the TV can natively play, it's fine.

OK, so here is the ffmpeg transcode command from the log:

Code:: 2012-04-22 16:18:18,729 DEBUG [ProcessExecutor] Starting C:\Program Files\Serviio\bin\\..\lib/ffmpeg.exe -i movie.avi -y -threads 4 -async 1 -vcodec mpeg2video -sameq -r 30000/1001 -g 15 -copyts -acodec copy -map 0:0 -map 0:1 -sn -f mpegts C:\Windows\TEMP\Serviio\transcoding-temp-5444-MPEG2TS.stf

Here's ffmpeg -i output:

This movie produces awful ghosting during the titles/credits and pretty bad ghosting (fuzzy edges, like you're seeing double) overall.

1. I can't find -sameq in the ffmpeg documentation, has it been deprecated?
2. What ffmpeg params do you suggest I tinker with or add?
3. Is there an easier way to customize the ffmpeg command without the PERL kludge posted in the forums?

Interesting, looks like they removed it from there recently. Try to use -qscale 1 instead (should be the same as sameq)
