[linux-dvb] How to send A/V-Packets without blocking the whole device

["Roland Praml" <pram2000@web.de>]

Hi,

I'm working on an DVB-output extension for the SDL-library, so you can use
SDL-ported apps on your TV-screen:

(sorry in german!)

Currently Audio and Video works separately well. But if I send audio and
video
packets to the device, the device is blocking when the queue is full and
doesn't
accept audio or video packets.

E.g. When the video encoding thread sends more video packets to the device
than the
device can process the whole device is blocking and doesn't accept audio
packets either.

So is there a possibility to ask the driver how much video and audio packets
I can send
without blocking the whole device?
