How to really disable transcoding?

[Radiorama]

Hello everybody,

I recently discovered UMS, and it's great! The resume playback feature is well worth the whole program.

Anyway it seems whatever I do I'm totally unable to stop UMS from transcoding. My renderer is a Sony Bravia KDL-42W828B connected via Wi-Fi. I'm trying to play a mkv file containing 1xXviD + 2xMP3 + 1xUTF-8.

I tried all of the following, to no avail.

* Typed "avi,mpg,mpeg,mkv" in the "Skip transcoding for the following extensions (comma separated)" box under Transcoding Settings.

* Added "CustomFFmpegOptions = -c copy" to the Sony-BraviaW.conf file as suggested here: viewtopic.php?t=2707 .

* Added "StreamExtensions = "avi,mpg,mpeg,mkv" to the Sony-BraviaW.conf file, both with MediaInfo = true and with MediaInfo = false.

* Replaced the "Supported" section of the conf file with what is suggested here: viewtopic.php?f=9&t=3941 , both with MediaInfo = true and with MediaInfo = false.

Is there a definite way to prevent UMS from transcoding? Did I miss something?

Thanks,
Radiorama.

Don't know if this is what you want, but you could disable all the engines in the GUI (Left side "Video Files Engines")
Klik on an engine, and then click on the cogwheel (next to up/down arrows @ bottom)

Another way, i guess, is to define all "supported formats" in the conf file.
Just add any/all file types. ( see DefaultRenderer.conf, or look for file types in some of the other conf files. )

Note: With last option, i guess Transcoding still might be happening if subtitles are involved. (i think thats whats happening in your case)

Not sure why my previous attempts misfired, but I got it working now.

Tracing back all the changes and doing a bit of experimenting, I found that two simple steps suffice to stop UMS from transcoding. I summarize them below for the benefit of those who may be confronting the same issue.

1)Edit Sony-BraviaW.conf changing MediaInfo to false.
2)In the "Skip transcoding for the following extensions (comma separated)" box under Transcoding Settings, type "avi,mpg,mpeg,mkv" or whatever set of file extensions you don't want transcoded.

Best,

You are most certainly right. At some point while playing around with supported formats in the conf file I got .avis to stream, while .mkvs with subtitles kept being transcoded.

In the next version (6.5.2) it will be possible to disable transcoding completely by setting this in UMS.conf:

Code: Select all

disable_transcoding = true

Disabling of transcoding per extension has also been fixed.
