[Github #670] AAC bitrate 96kbps maximum

Post by mccartybr » Mon Apr 10, 2017 11:59 pm

Please describe the problem in as much detail as possible:
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):
Ubuntu 16.04

Where did you download HandBrake from? handbrake.fr or somewhere else?
