# Feature description:

When transcoding is enabled over Wi-Fi or a mobile connection, add an option to disable transcoding if the source format is already lossy (e.g., OGG, MP3, etc.).

### Problem solved:

Since the source format is already compressed, there is no need to compress it again into another format.

### Brought benefits:

Save CPU resources by not re-encoding the file and avoid losing audio quality due to the process.

I guess you are using a Subsonic server. This needs a new API for it that is in the work in Open subsonic.

Sorry for not mentioning it earlier, I’m using Jellyfin 10.10.6 in a docker container.

Then it should not transcode if the bit rate is less than your limit. And a new Jellyfin bug.

Please provide logs showing this.
