That's my app does:
1.- Open the device for capture
2.- Set the access mode SND_PCM_ACCESS_RW_INTERLEAVED
3.- Set format 16 bits (SND_PCM_FORMAT_S16_LE)
4.- Set channels 2 (stereo)
5.- Set buffer time near 1 second
6.- Set period time near 0.1 seconds
7.- Copy the hardware params to alsa
8.- Set start threshold (0x7fffffffff -> Explicit start)
9.- Set transfer align 1
10.- Copy the software params to alsa
read loop:
- Read 'period size' frames (snd_pcm_readi)
How can i get the timestamp of the first frame read? If i use
snd_pcm_status_get_trigger_tstamp i obtain the same timestamp all the times.
If i use snd_pcm_status_get_tstamp i obtain the "now" time. Is there any way
to get the timestamp of every period.
Thanks
