AVI file demuxed with one audio frame per sample

[t.rapp]

Summary of the bug:

When demuxing the PCM audio stream of some AVI files FFmpeg generates one frame per input sample and passes it to the filter pipeline, leading to performance issues. The input AVI file contains audio data interleaved with video, having two audio packet per video frame (20ms, 960 samples).

Attached is some minimized example file that triggers the issue with current git head. The example below uses the "ashowinfo" filter to indicate the number of samples per frame.

How to reproduce:
