Transcoding HLS streams to MP3 output

stream.convertor: C:\Program Files\FFMPEG\ffmpeg.exe
stream.transcode: aac:mp3

I would expect the AAC streams to give me a top notch MP3 sample rate but it isn't it is 128 kbps rather than 320 although the AAC is running at 320. I'm wondering whether when you called the FFMPEG library you may have picked it up at the default setting ?. I have used to different FFMPEG libraries in case the issue was coming from there but they both give me the same result.

I've just tried this and like you I'm surprised that ffmpeg doesn't use the sample rate of the input stream when encoding the output stream. It looks like MinimStreamer will need to detect the sample rate of the input stream and set this explicitly for the output stream.
