Subject: Re: playback delay and problems with simultaneous playback/capture
Date: Thu, 07 Jan 2010 16:49:54 +0100 [thread overview]
Message-ID: <20100107154954.319460@gmx.net> (raw)
concerning the first point, I did some measurements...
the file I used has a length of 1488 ms
trigger start jiffies=7466937
trigger stop jiffies=7468172
difference = 1235 (1235 ms)
pcm prepare jiffies 2=6761125
trigger start jiffies=6761126
trigger stop jiffies=6762361
difference = 1235 (1235 ms)
trigger stopped, buffer empty, stop decoder jiffies=6762684
difference = 323 (323 ms)
so I was wondering, why the difference between trigger start - stop
is not 1488ms but 1235ms. I still guess that it may is a wrongly updated
pcm pointer?
Thanks for your help,
Max
