Hi to me it doesn't seem to be clear if you understood the difference<br>between v4l and dvb?<br>Video4linux is usually used for analogue TV<br>(<a href="http://en.wikipedia.org/wiki/Analog_television">http://en.wikipedia.org/wiki/Analog_television
</a>)<br>dvb for digital transmitted TV.<br>So are you trying to write a driver for the analogue or the digital part?<br>There's nothing wrong to use the v4l API for analogue TV.</blockquote><div><br> I'm trying to write a driver for the digital part,
definitely. But I was wondering if the device /dev/dvb/adapter0/video0
would be able to deal with all the possibilities of a video decoder
because in the DVB API, we can see (at the beginning of the Chapter 4):
<br>" Note that the DVB video device only controls decoding of the MPEG video stream,<br>not its presentation on the TV or computer screen. On PCs this is typically handled<br>by an associated video4linux device,
e.g. /dev/video, which allows scaling and<br>deļ¬ning output windows. "<br><br>I'm not sure I'm clear enough...<br></div></div><br>-- <br>Thomas Gambier<br>
