Now that the kfir driver has been ported to kernel 2.6 (thanks to Anssi Hannula) I'd like to get back to a problem that has been bugging me ever since I'm using the kfir card.
When I load the kfir driver with
insmod kfir.ko vidinput=0 vidrate=3000000 debug=0 streamtype=4
so that I get a Transport Stream, and then open the /dev/video device for reading, I get a perfectly ok TS. However, if I close /dev/video and open it again, the video resulting from the TS shows block artefacts at the bottom of the screen. Every time I repeat this close/open procedure, the area that is distorted grows further up, until after some 5 or so cycles the entire screen is full of artefacts (and there are also sound distortions).
Only rmmod/insmod of kfir.ko fixes this, which means that I have to unload/load the driver before every recording.
Does anybody (Anssi?) have any idea what might be the cause for this?
Klaus
