Video aspect 720 x 304 problems

Hi Paul

Sadly no success this time, transcoded without error but TV reported "Not Supported", as did my PC using DivX Player. Seems to error the codec for audio.

Hi Paul

Ref the file that doesnt need to transcode, the details of my "HD MPEG" video are:

This video was the 720 x 304 aspect that plays correctly as as MPEG, streams without transcode on the "No TS" profile but transcodes with the "2009" profile. If this didnt transcode at least i can stick with the 2009 profile.

Thanks for your help so far, i am trying to get to grips with ffmpeg to see if i can successfully get 6 channels but my knowlegd is 0% at the moment,

Hi Paul

Just a bit more info, may help on the avi/ac3 problem. To do a simple test I took a working avi 6 channel file and forced a transcode to what should be the same, but the resulting transcode using your new ac3 option shows with no audio on the TV, the ffmpeg info is ...

This is the file that doesnt work, taken from a transcoded file back in as a normal library entry.

The only two differences i can see are the bit rate is 2551 vs 2555 and probably the significant difference is the working one is xVid and the one without sound is DivX.

Hi Steve,
we have updated the Panasonic Viera (2009 Models) profile so that your mpeg2 file will play natively and the avi encoding will use the XVID codec tag instead of divx, download the updated profile from the same location as before (there are two files in the zip that you need to extract to your device profiles folder).

[Roofus]

Hi Paul,

The mpeg now plays native so that's a result. Still no joy with avi, the aspect is fine but no audio indicated by tv, speaker symbol crossed out. there still seems to be differences in the audio settings, not sure if it's the Mode extension : CM (complete main) or Format settings, Endianness : Big, the audio codec or interleaved settings.

Would it be possible for the mpeg option to force the aspect and pad the video instead? Would that mean it could stream and transcode at the same time?

Cheers

Steve

Hi Steve,
we have just released Mezzmo 3.0 which has a modified Panasonic Viera (2009 Models) profile for you to try, please try updating and then pre-transcode your file to avi and see if the audio and video play.

It is possible to adjust the device profile so that the video is transcoded while maintaining the aspect ratio by padding the video with black bars, this might still be fast enough for transcoding on the fly, please try Mezzmo 3.0 and if the avi pre-transcode does not work we can send you an updated profile that will pad the mpeg video.

[Roofus]

Hi Paul, updated to 3 and retested. All normal native playback ok inc. my "hd mped". Transcode on the fly all working but aspects still not fixed when source is not 16:9 most obvious with original post but also with my 1920:1040 which I have quite a few mp4's and mkv's.

I think ffmpeg and ac3 5.1 is not going to work, it now refuses to play completely, either ac3 or mp3. I'm guessing it's the codec again and there seems to be an old problem with ffmpeg and the audio codec not being 2000 but 00001000-0000-0020-8000-00AA00389B71 instead which does seem to be a topic of complaint with ffmpeg. It seems some players are fine, some are not with my tv the latter.

So can we try padding to 16:9 with mpeg?

Cheers and thanks again

Steve

Hi Paul,

I realise you must be very busy what with a new release etc but is there any chance of a profile to try to pad the video. I have tried myself using ffmpeg to manually scale up and pad with partial success (worked padding avi but not mkv & mp4) but i would prefer not to have to re-scale and pad my videos before i add then to my library for obvious reasons.

Cheers

Steve

Hi Steve,

Sorry for not getting back to you as yet. Please send a new email to us at support [at] conceiva [dot] com and we'll provide a device profile with padding enabled.

[Roofus]

Hi Paul

Thanks for the new profile, some good news, some not so good. Firstly a success, my 720x304 file now looks great with black bars top and bottom.

Sadly my celebrations were slightly too soon, i have now noticed my mkv files which are 1280x720 now appear with black bars top bottom, left and right in a small window in the centre of the screen which is very odd.

Also i have some videos that are 1280 x 528 (mkv) and they also exhibit the same problem.

Lastly i have a few 1920 x 1040 mp4's and they are not getting any padding top or bottom, although the distortion is small its still noticable.

Any ideas?

Lastly and not really related but i noticed it whilst testing different files, i added height and width columns on the details view and there are not details shown, any ideas why, they show in the property windows which is what i am using to pick test files.

Thanks again.

Steve
