Subject: snd_pcm_sw_params_set_start_threshold() functionality
Date: Mon, 29 Oct 2012 16:50:06 +0530 [thread overview]
Message-ID: <508E6666.5080402@sasken.com> (raw)
Hello,
snd_pcm_sw_params_set_start_threshold() API description
explains, "PCM is automatically started when playback frames available
to PCM are >= threshold"
I want to know, whether above pre-buffering(threshold)
mechanism is only during the start of playback ?
OR
Also if my playback device goes to XRUN state, Again next
time when i prepare my playback device using snd_pcm_prepare(). Again
the prebuffering (threshold) will occur since i have set
snd_pcm_sw_params_set_start_threshold() to N periods in software params.
Best Regards,
Thanks in advance,
Irfan...
