In 2012, GiP was still using rtmpdump and accessing programs via Adobe
Flash. You can run those programs through ffmpeg yourself if you want
to verify that they are correct M4A.
ffmpeg -i "input.m4a" -vn -acodec copy -bsf:a aac_adtstoasc "output.m4a"
If you don't want podcasts, specify an alternative version or list of
versions in either the --versions parameter, or the versions option
within the config or preset file. --versions=default should avoid podcasts.

For presently available modes it is not quite right to say that ffmpeg
is used *during* downloads. ffmpeg was used at one stage to download
HLS and HAF modes. It was replaced with a stand-alone downloader which
is now used for HVF.
ffmpeg is used *after* downloads to re-multiplex to a different
container. If you want to see what ffmpeg is doing use
--ffmpegloglevel=info
This is a heavily abbreviated explanation. If you want more detail see

Hi Richard,
Many thanks. I asked as I am still trying to get to the bottom of my
problems with some GiP radio downloads and the Linn DS playing problem
however these date from 2012 and I note things have changed. Would
radio programmes from then have been re-muxed once downloaded? This is
not critical but there is a Tag which might have been stripped
(correctly) which would account for re-muxing by ffmpeg.
I am just trying a new GiP installation on my laptop and tried it on The
News Quiz Extra. Everything worked but I see the file came as a
podcast. Is this new. Should I have added parameters to get file not
being a podcast?
I just used the --pid to get the programme I wanted.
Many thanks for your help once more.
Regards,
Alastair
