yes, "aplay -f dat < /dev/video24" works correctly. > then if it's working, you can use mplayer or > sox or something to reincode it to wav. as far as sox goes: ~]# sox -tossdsp -swr48000 -c2 /dev/video24 /data/rec/soxtest.wav sox: Failed reading /dev/video24: Unable to reset OSS driver. Possibly accessing an invalid file/device what is wrong here? (as far as mplayer: haven't been able to compile it on my FC4; "make" breaks at ' libpostproc/postprocess.o' and 'libavcodec/libavcodec.a' and 'libavcodec/libavcodec.a', but, i suppose, that's not on-topic.) > > > 2) has anyone succeeded in capturing raw video ( /dev/video32 ), using > > transcode, for instance? > > Or, using any other app, for that matter? > > Please look at the list archives, this was just discussed recently. > How to use mplayer / mencoder with /dev/video24 is discussed there > also, as that's how you get audio when capturing video from > /dev/video32. thanks. Will look when mplayer is functioning. andrew _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
