The read() bug isn't major for me, as I can just use a slightly modified libv4l2 to cope.

If we can't, I'll be tasked with working on this; I take it you'd prefer to have ALSA added to the driver than for me to teach Xine to read from /dev/video24 for PCM audio? In any case, I have some more work to do on the reworked input_v4l for Xine, as I need to get it into a state where I can work with the Xine guys on merging it into their mainline. This will have to be finished before I can really dive into the cx18 driver. -- Thank you for the offer of help - I'll let you know if I'm going to start working on ALSA support in cx18, Simon Farnsworth -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
