I read this mail posting about flush operation.
https://www.mail-archive.com/linux-media@vger.kernel.org/msg41867.html
My user side application talks to v4l2 driver like this, as an
example, I put qbuf/dqbuf loop 10 times:
open
stream on
for (int i = 0; i < 10; i++)
qbuf
dqbuf
// process the buffer
stream off
close
>From the message, it said "close/streamoff() does an implicit immediate stop.
"
But how can I 'flush the stream before my last dqbuf() buffer (i.e.
when i is 9)? When close/streamoff() does an implict stop/flush, I
have already dequf my last buffer, so my application won't see the
'flushed' content.
How can I fix this?
Thank you.
