Panasonic Viera GT30 series support

[baletka]

Hello, I'm trying the trial version of your software and I'm worried about the support for my Panasonic GT30 TV. While it is recognised as Panasonic Viera 2011 model, it keeps transcoding files that it doesn't have to (the tv has support for mkv and mp4 files with h.264 codec). It is annoying, specially as high quality HD movies seem to be too much for my CPU, so I have to wait hours of pretranscoding to be able to watch TV.

Hi,
FYI, I also have a GT30 - but in my case, the MKVs do not require transcoding. MP4s do - but I was expecting that as it is my understanding that only MP4s created by Panasonic equipment (video cameras?) can be handled natively by the TV.

All the MKVs have been created using Handbrake and use x.264 codec. Perhaps you have a different codec inside the MKV container ?

The "Panasonic Viera (2011 models)" device profile shouldn't transcode MKVs supported by the TV. If it does, then it's likely that the file is not compatible with the TV (for example, it could have a high video profile level that the TV cannot play). Do those files play if you turn off transcoding?

@Bodders: I didn't know that about mp4, but I did notice on the DLNA screen that I couldn't even press the play button on the mp4 movie.

@Dennis Yes, they play normally if transcoding is turned off.

Sample ffmpeg info, plays normally without transcoding:

Sample 2, does play without transcodding, but image is lagging badly (sound is normal):

Unrelated info, it seems mezzmo doesn't fully transcode a file. It stops after around 1GB (not always the same). It's streamed normally to the tv and the duration is right, but somehow time played goes faster than it should, so 150 minutes becomes something like 20 minutes (and movie ends after 20 minutes). Drive is formatted in NTFS and there's more than 400GB free space left. I don't think any error is shown, but it is possible I missed it. Anywhere I can see log of transcoding?

Thanks for the file info.

The second file has video profile level 5.1 and I think that's the reason it doesn't play properly. Our device profile currently specifies a maximum video profile level of 4.0 for the Panasonics, but we can raise it to 4.1, since the first file you have played fine. Please send a message to support and I'll send you an updated device profile to try.

You can find transcoding logs in the Logs folder - you'll need to enable logging first (see this thread: http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) and then try re-transcoding the file. You can also send the logs to support, if you'd like me to take a look at them to see if I can spot why the file is not fully transcoded.
