Help regarding Audio Bitrate

[KosmicDaKerbal 0]

Is there any way to change the bitrate of audio to even lower than 128 kbps? i have set a network bandwidth limit of 0.25 mbps on my emby server, and the 128kbps audio bitrate becomes a bottleneck for the video.

Yes - for transcoding only, you need to install the Diagnostics Plugin - and apply the following substitution -

64000 is 64K - but take it as low as you need.

Note the Stats for Nerds still reports 128K, but ffmpeg is definately using this lower value in the transcoding log.

I hope this helps.

Note - this is not permenant, you'll need to re-apply after every emby reboot I'm afraid.

a. does it also include windows reboot?

b. if yes, is there any way of making some sort of .bat script that would replace this line everytime at startup?

c. can FFmpeg itself be modified to transcode to a lower bitrate by default?

a - Yes - a reboot will lose the settings

b - Not that I'm aware of

c - This is not an ffmpeg default setting - it's what emby passes it during a transcode.   This likely 'could' be changed - but the bitrates you are using are extreme - for the majority of users, 128Kbit for 2 Channel MP3 is a reasonable value.

May be able to provide some further insight, but the diagnostic plugin, as the name suggests, is just for diagnostics but will 'work' by manipulating the ffmpeg syntax during a transcode.
