AVI transcoding could be better

hello,

I have a Panasonic 50UT50 which has native mkv support but no AVI support.
I have Serviio up and running and using the viera2011 profile which has Serviio transcoding AVI files as follows:

<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3">
<Matches container="avi" />

The results on the TV are not so good. Specifically:
-the audio is cloudy and a little noisy
-the aspect ratio is forced from the original 4:3 to 16:9
-video edges are not crisp
-after about 10 mins of playing it stops and an error message shows on the TV

As a test, I tried using HandBrake to transcode the entire .avi file ahead of time using the following HandBrake settings: Container=MKV. Video=H.264 Audio=MP3 passthru.

Now when I request, Serviio serves up the new .mkv file, does not transcode, and the results are really good. Audio is clean, aspect ratio is correct at 4:3, video quality is quite good and the playback no longer dies after 10 mins.

I thought I would tune the Serviio profile so the transcoding matches what HandBrake did but alas those targets don't seem to be available.

So... is there a plan to add more container and codec targets in Serviio ? or am I missing something?

thanks for reading this far. :)

post your server logs after it fails so we see what's happening when it fails.

Also you may want to try adding aBtrate to your profile for the sound issues, I had a similar sound issue with AVI's that was resolved with this setting.

You can try transcoding to mp3 instead of ac3 and add DAR="16:9" to the transcoding config.
