I have a FLAC audio file (24bit/192Kbps) from which I want to create a HLS packaged adaptive bitrate stream, the highest quality stream being the input format, so FLAC (24bit/192Kbps) and the lower format streams being AAC at different bit rates.
I can do this with AWS MediaConvert or AWS Elastic Transcoder with regard to the AAC outputs but it doesn't support creating the FLAC outputs as far as I can see.
Is there a reason I shouldn't be trying to do this? Assuming that it is a perfectly valid objective is there another tool/service to do the job or perhaps I need to code something up myself around ffmpeg?
We are currently reviewing FLAC as a roadmap feature and intend to include it in an upcoming MediaConvert release. Please check out the what's new post for released features in MediaConvert.
