My grab application works OK with V4L as far as video is concerned, but
I have a problem with sound (using OSS): I would like to have exact
timestamps on every sample in the sound stream, and I couldnt find
anything about that in any OSS documentation I could find on the web.
Any recommendations?
OSS doesn't provide timestamps. Simply call gettimeofday() after
receiving a sound buffer.
As is often the case with 'simply...'-stic solutions (in French, we call
that a YAKA) it does not work. Because (1) there could well be *another*
buffer already available in the kernel (2) the process could be
rescheduled between the read and the gettimeofday.
