Audio bitrate is not set

Post by Dukers »

Using HandBrakeCLI 5229svn x86_64 on Windows.

Code: Select all

--aencoder copy --audio-copy-mask aac --audio-fallback ffaac --ab 128
But HandBrake when convert to AAC always set the audio bitrate to 160 kbps no matter what I put in the "--ab" option.

Code: Select all

[22:09:52]  * audio track 1
[22:09:52]    + decoder: Unknown (mp3) (2.0 ch) (track 1, id 0x1)
[22:09:52]      + bitrate: 192 kbps, samplerate: 44100 Hz
[22:09:52]    + mixdown: Stereo
[22:09:52]    + encoder: AAC (ffmpeg)
[22:09:52]      + bitrate: 160 kbps, samplerate: 44100 Hz

I was under the impression that the audio bitrate was set by -B.

The log should have the complete CLI string at the beginning. Could you post that please.

-B and --ab are supposed to be equivalent:

Code: Select all

  -B, --ab <kb/s>         Set audio bitrate(s)

Not if you're using the CLI.

Oh dear! I just went and looked at some of the threads in the CLI section, and I see that it doesn't include the settings.

The bitrate applies to audio encoders requested explicitly, not the fallback.

I guess having a fallback mixdown & bitrate is a good idea, though. Maybe I'll add it a some point.

However, given that you're using faac, 160 Kbps is hardly overkill, IMO.
