--- Comment #12 from Jean-Baptiste Mardelle <[email protected]> --- So my change to make audio bitrate adjust with the quality slider does not impact the custom profiles. In fact, the FFmpeg native aac encoder does not really provide real CBR when using the audio bitrate setting (-ab or -b:a), but ABR (Average Bitrate). This is a limitation of the FFmpeg aac encoder. In my tests, using the audio quality method (labelled VBR - Variable bitrate, with a quality of 2) gives an output that is marked as constant in MediaInfo. Note that you cannot manually adjust the bitrate using this method, but a value of 2 (the maximum) results in about a bitrate of around 380k. I will update the aac quality setting that is currently a useless 0-50000 range to be percent based so that it's a bit more understandable. Not much else we can do. Also note that having aac bitrate more that 256k does not seem to make much sense quality wise.
