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.

Thanks Rodeo.
