Video Upscale

[mtalbot]

Hi,
I have a pair of Samsung DLNA TVs. Both are Series 6 B. So far verry impressed with your product, best on screen library I have seen and I have seen many. I have one remaining issue. I want to stream ripped DVDs from my PC that are natively 576 or 480 lines. The TV receives them and since it is a 1080 screen plays a small window. Choosing fit is not scaled up correctly. Is there a way to upscale from the Mezzo end or do I need to change/convert the files
Thanks in advance.

Hi Mark,

Sorry for the delay in replying, I was away.

Can you please send me (or post here) FFmpeg information on one of those files so that I could better understand whether they're passed through or transcoded and I'll be able to reply better to your question then.

Thanks!

Hi Dennis,

The MezzmoMediaServiceTranscoder.txt file is empty so I assume it is not transcoding. I followed the log process as per one of the threads.

Is there something I need to do to get the transcoder going to the 1920 x 1080 resolution.

Thanks

Mark

Hi Dennis,

Just found this:

Hi Mark,

The best way to check if the file has been transcoded is to see whether the transcoding folder is empty or not, but looking at the transcoding log is also a good hint of course. You are right, that file should be passing through and looks like it is.

If you wish to upscale it to 1920x1080, that's possible, but you will lose some quality of the video by doing that. Please send a message to support (at) conceiva (dot) com and I'll provide you with instructions on how to modify the device profile to accomplish that.

That file should really be stretched properly by the TV itself. I'm surprised it's not displaying it properly. The one reason I can think of is if your TV is NTSC and the file is PAL-dimensioned, maybe it doesn't like that. Perhaps if we resize it to an NTSC format, it'll display properly (without upscaling).
