now i saw that this warning in the log-messages was the result of wrong format-settings. but that changes nothing - without any error or warnigs i can't read the YUV-stream with any application. the v4l-info displays the correct settings and the applications get the whole information about this device, but when they start they aren't able to read the data. i don't think i am the only one who wants to read from /dev/video32, so could someone who has used this device already please give me some hints what could be wrong here or how to read this stream? again - mpeg2 from /dev/video0 works. all comments are welcome thank you lukas _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
