[FFmpeg-devel] [PATCH] Auto insert resample filter between audio filters during sample format negotiation

[S.N. Hemanth Meenakshisundaram]

Auto insert af_resample between audio filters with incompatible sample
formats. This patch works on top of the latest af_resample patch sent
earlier.

Passes make test and auto insertion can be tested by modifying af_anull
to accept only a specified format, say SAMPLE_FMT_FLT. Then doing

./ffplay -af anull in.mp3
