Comment (by korli):

Thanks for the feedback!

I would still use {{{av_sample_fmt_is_planar}}} to detect planar

formats, instead of trying to guess from the input/output sizes.

Yeah I guess.

Also, the libswr is able to do other conversions (float<>int or

whatever), which may be required by some codecs where only float output is
supported.

AFAIK the plugin maps the avcodec sample format to the media kit sample
format, this means we don't require any format. I don't understand what
might be required then.

So, this needs careful testing with a lot of audio/video files (for

example there are a lot at http://samples.ffmpeg.org), to make sure we
don't need something else.

Sure.

It's a bit sad that we can't get libswr working and we have to rewrite

it, however :/

Yeah, or avfilter. In this case though, we don't really need some audio
conversion, just another structure. IMO it's not too bad if we can skip a
dependency on libswr.
