Hi Carl,

No, I didn´t managed to decode a LATM file as shown in the source code.
I also made a few tests with other LATM files, created by different
applications - without success.
That is a little bit strange, because everything works fine if I play the
file as it is with ffplay.
Maybe there is something wrong with the initialization part of ffmpeg in my
sample code ?

Just the ADTS version of the files are ok.

I can try to remove the LATM header and create a ADTS header, but I am not
sure.
Any suggestions ?

Thanks,
Sven
