We are trying to trans-code audio into ADPCM format (codec: adpcm_ms) for use by XAudio (DirectX SDK).

The problem is that XAudio seems to require adpcm blocks of size 32,64,128,256 or 512. FFmpeg always generates blocks of 1024.

It would be nice if there was a parameter for adpcm_ms to set the blocksize.
