Transcoding some files when it should not

**rsxstewart** · 01-26-2012, 07:42 AM

Hello,

I am streaming DLNA to a LGLW6500 TV. Mezzmo is trying to transcode some files, but not others. I don't think the software should be transcoding. However, even when it does transcode it will only play 20 seconds with of video before it says "Too slow" on the transcoding tab. CPU is i7 930, set to normal usage.

Here is the profile of a file it trys to transcode:

bump please

Can you please tell me which device profile you are using (check the Media Devices dialog)?

**rsxstewart** · 01-29-2012, 04:42 AM

The device name is LG BluRau (LPCM)

Neither of those files should be transcoded using that device profile, as they appear to have identical codecs and thus they should be sent natively to the device.

Please enable logging (see this thread: http://forum.conceiva.com/showthread...nostic-logging) then browse to a folder with those files on your device and try playing the one that starts transcoding. Then, after a few seconds, stop the server and send in the logs to support and we'll investigate.
