[linux-dvb] Bug in drivers ringbuffer

["Peter Seyringer" <dvrproject@seyringer.priv.at>]

Hello!
Hello Marcus!

Im writing now on my teletextdecoder for VDR. But i always have troubles to view my txt picture with the video_stillpicture command. My picture is a i-frame. Now i have the problem, that i must fill up the ringbuffer, that the driver shows the picture on my tv. So i paste them mutible time to the buffer.
But the Problem was that i only get a part, half screen or only some lines, on the tv screen.

After some times playing with the driver code i found out, if i change the line
                ring_buffer_flush(&dvb->avout);
to
                ring_buffer_flush(&dvb->aout);
(i know its for audio) but now i don't have to fill up the buffer and the picture is shown on the tv screen without any problem.

Can you tell me why it works without flush the videobuffer?

Peter
