[FFmpeg-user] ADPCM block size for XAudio

Dear ffmpeg team & users,

I'm using the MonoGame framework for development. It uses ffmpeg to ADPCM
encode wave files. Playback is done using xaudio.

Problem is that ffmpeg always uses a blocksize auf 1024. xaudio only
supports block sizes of up to 512. It would be good to make the blocksize
configurable to make it compatible.

Someone else from the MonoGame community already created an issue for this:

Do you think someone will build a fix for this in the near future? Any
suggestions for a workarround?

Best, Martin
