Hi folks !
I'm working on implementing VideoIO for my hardware, and as I have now
successfully grabbed my first short pieces of video, I wonder how one
can get Linux to show a decent behaviour with respect to streaming data
to disk.
Without any special measures, the cacheing will cause random "hicups",
where the data rate will stall for a few seconds while buffers are being
flushed, and then continue at high rate.
However for streaming video, it would be better, if I rather had a constant
(lower) datarate.
fflush doesn't seem to count at all. Maybe I need to open with O_SYNC, but
then - I don't care about a little buffering being done (I assume it would
be beneficial, just in case stuff happens like cron running or similar), it
just shouldn't get excessive.
Any hints appreciated.
CU, ANdy
