Comment (by pulkomandy):
We always request a sample format that matches what we want to output, but
some codecs in ffmpeg may ignore the request (we also request non-planar
output, and they ignore that). It depends on the format used, and also on
the version of ffmpeg.
This is why I tried to go with swr: it would solve all the possible
mismatches and always make sure we ouput exactly what was requested. It is
a bit nicer and more predictible for apps and they don't have to do the
format conversion on their side this way.
But, as it doesn't work reliably, we can go with a simple rematrixing as
you did, it should cover most cases for now.
