Hi! Since r3404 (ivtv-0.4 branch / DMA fix), I have the following problem: Every time I want to set a new channel (hmmm... I don't remember if I have tried to set the current channel again via ivtv-tune... will try tonight...) via mythtv or via ivtv-tune -c, my PVR 350 (NTSC) output (/dev/video0 or the tuner?) hangs if the output/tuner is already in use. Here my step by step testcases:
~~~~~~~~~~~~~~~~~~~~~ Testcase 1 (no problem) ~~~~~~~~~~~~~~~~~~~~~ ivtv-tune -c (any channel) /dev/video0: xxx MHz (Signal Detected) cat /dev/video0 > /tmp/test1.mpg (dump tuner output as expected) ctrl+C ivtv-tune -c (any other channel) /dev/video0: zzz MHz (Signal Detected) cat /dev/video0 > /tmp/test2.mpg (dump tuner output as expected) ctrl+C etc... ~~~~~~~~~~~~~~~~~~~~~ Testcase 2 (to reproduce the bug) ~~~~~~~~~~~~~~~~~~~~~ ivtv-tune -c (any channel) /dev/video0: xxx MHz (Signal Detected) cat /dev/video0 > /tmp/test3.mpg & (dump tuner output as expected in background) ivtv-tune -c (any other channel) /dev/video0: zzz MHz (Signal Detected) (no more output from /dev/video0) kill %1 (kill my background process - cat /dev/video0) cat /dev/video0 > /tmp/test4.mpg (create a empty file) ctrl+C I can recover by reloading the firmware (I have not tried other means, suggestion?) ivtvctl -H ioctl IVTV_IOC_RELOAD_FW ok Conclusion: if /dev/video0 (or the tuner?) is already in use when I set a new channel, the output/tuner hangs for all revisions since r3404 (I use r3375 but suffer of DMA errors). I see nothing from ivtv in logs files... so if you want more details, please let me know how to proceed. Below the INIT IVTV log (with r3482)... BTW... the 0.4 branch at r3482 on the make command returns an error (my quick and dirty workaround was to comment the if(is_pal) and related PAL code in cx25840-vbi.c) ... make <snip> cx25840-vbi.c: In function `cx25840_vbi': cx25840-vbi.c:175: `is_pal' undeclared (first use in this function) cx25840-vbi.c:175: (Each undeclared identifier is reported only once cx25840-vbi.c:175: for each function it appears in.) make[3]: *** [cx25840-vbi.o] Error 1 <snip> Thanks a lot for your great work..!
