Valkyria Chronicles 2 - ULUS10515

[Szarikow]

(from wikipedia) "FFmpeg also has ADX support implemented, however, its decoder is hard coded so can only properly decode 44100 Hz ADXs."
^ http://en.wikipedia.org/wiki/ADX_%28file_format%29

I've seen that., that's why I checked file headers if the ADX files contain 44.1kHz streams. I also made sure those were adpcm streams and not MPEG2 ones. It appears ffmpeg included with jpcsp can't parse ADX files (container), but can decode ADX adpcm stream.

Back to Jpcsp, I disabled the media engine and it still plays the voice audio in Valkyria Chronicles 2 so that means Jpcsp is not using ffmpeg, it must have its own internal decoder.

That is quite interesting.
