I had a look at the Spotify C API, and found that they were using the following code to output music from Spotify: snd_pcm_open(&h, dev, SND_PCM_STREAM_PLAYBACK, 0).
I want use this function instead:
int _snd_pcm_file_open(snd_pcm_t **pcmp, const char *name, snd_config_t *root, snd_config_t *conf, snd_pcm_stream_t stream, int mode)
The function is found here:
I'm not able to find anything in the documentation explaining what the two parameters snd_config_t *root and snd_config_t *conf is.
What I'm trying to achieve is to write the stream to a file, and then read it from another application. But it would be even better if I could make the C application write to standard output.
Can anybody help me with this?
I'm not very experienced with either C programming or streaming, but I would really like to make this work.
