Hi,
digging into the pjsip source code, wavplayer files, here are the cases in which the error PJMEDIA_EWAVEUNSUPP would occur:
- Must be PCM with 16 bits per sample
- Block align must be 2*nchannels
- Invalid file length (wavehdr.data_hdr.len > fport->fsize_list[index] -
fport->start_data_list[index])
- WAV playlist error: file '%s' has differrent number" of channels, sample rate, or bits per sample
The files are wav_player.c and wav_playlist.c if you want to have a look.
Hope this helps.
Chris
