Transcoding audio via command line
Posted: 10 Apr 2013 19:31
Hello,
I am looking into writing some scripts to convert audio files from one format to another (such as WAVE to MP3 and MP3 to WAVE)
I found this link online and tried to run the sample script on a sample song (within that directory), but it no longer seems like it's a valid syntax.
I looked at the docs and found the transcoding documentation, but it didn't come with examples and I am not sure how to get it up and running. Could someone point me in the right direction and maybe give me some sample code on how the docs work for transcoding audio. Thank you!
The docs that I believe are relevant:

Destination audio codec
This is the audio codec that will be used.
--sout-transcode-ab=<integer [-2147483648 .. 2147483647]>
Audio bitrate
Target bitrate of the transcoded audio stream.
--sout-transcode-alang=<string>
Audio Language
This is the language of the audio stream.
--sout-transcode-channels=<integer [-2147483648 .. 2147483647]>
Audio channels
Number of audio channels in the transcoded streams.
--sout-transcode-samplerate=<integer [-2147483648 .. 2147483647]>
Audio sample rate
Sample rate of the transcoded audio stream (11250, 22500, 44100 or
48000).
--sout-transcode-audio-sync, --no-sout-transcode-audio-sync
Synchronise on audio track (default disabled)
This option will drop/duplicate video frames to synchronise the video
track on the audio track. (default disabled)
--sout-transcode-afilter=<string>
