Transcode - only audio ?

Post by adgen »

Hello WMS - guys.

First of all I have to congratulate to such a nice tool. It's great to have device-depended configuration options. I need this for my new (media) server, which has to deliver media content to 1-2 clients.

So I'm new to this, and I have a question: Is it possible to transcode only an audio stream and remain the video stream? In my case I've got an mkv-file with H.264 video codec and a DAC audio codec (DTS 5.1). I do not need a converted video but transcoded audi stream. Is this possible to safe some CPU-time?

Thx alot.

Bye.

This allows the profile "Movies - TsMuxer"

Ah, Ok.

I thought about that. I've already try this muxer, but the CPU had so much to do. I thought the only work for a muxer is, to select the audio stream data from mkv-file transcode it to 2 channel mp3 and wrap it into a transport stream. Is it feasible, that this is CPU consuming, even the video data is not changed?

Thanks again..

Bye.

"Movies-TsMuxer" at the moment does not change the video, audio transcoded into a format specified in the configuring the program (Settings-Transcoder-"Codecs, frame").

And what is the reason for the CPU workload?

What a CPU load of the processes in Task Manager?

Yes. Workload == CPU Time cosumed by trancoding process.
