HLAE + FFMpeg always uses ipcm audio format

[boytunp]

Whatever I pass as an audio codec, HLAE never really uses it and output video file's audio codec always ends up with ipcm. I suspect this is due to mirv_streams record startMovieWav 1 command to HLAE here which I guess creates a wav file. Is there any way to make HLAE use an audio codec?

I don't think so, even the game only support wav.
You could try to ask on the HLAE GitHub repo or Discord.

It was actually possible to resolve this problem by doing the conversion with FFmpeg.
It has been released in v3.14.2.
