AAC downmix forced to 96kbps #670

Closed mccartybr closed 7 years ago

mccartybr commented 7 years ago

Please describe the problem or feature request in detail:

Supply an mp4 input file with one h264 video track ac3 audio track 384 or greater kbps bitrate output to 1 aac stereo or dplii - aac downmix + ac3 passthru regardless of the bitrate settings for the aac track, the bitrate in the output (according to ffprobe) is always exactly 96kbps. By comparison, 'aac passthru', passing aac directly through handbrake with a bitrate greater than 96kbps, the higher bitrate is maintained with passthrough. this behavior is new for version 1.0.x; prior to that was able to downmix aac at 160 or 192kbps.

What are the steps to reproduce this problem:

downmix an mp4 file containing one ac3 audio track to aac

What version of HandBrake you are running:

1.0.3

What operating system and version and you running (e.g. OSX 10.11, Windows 7, Ubuntu 14):

I think this is the same problem as this https://forum.handbrake.fr/viewtopic.php?f=5&t=35980

Could you try setting samplerate to auto in audio defaults and see if it fixes the bitrate issue?

I'm going to assume the forum post is the same problem Should be fixed in 9a22ae2

Closing. If you continue having this problem after updating to a nightly build, feel free to let us know and we'll reopen.
