makeaccestarget audio stream bit rate lower than specs #9

Closed klipska closed 9 years ago

klipska commented 9 years ago

The access file created by the script has an audio stream bit rate of only 83.3 Kbps. We want it to be 160 Kbps and it looks like the code specifies 160 Kbps so I'm not sure what went wrong. I can send more info if needed, let me know.

The script uses libfaac to encode to aac but apparently this encoder does not support constant bit rate. See https://trac.ffmpeg.org/wiki/Encode/AAC.
