Only somebody with a bus analyzer would have had a chance to see that no cycle start packets were going over the bus anymore. Kernel says this when the camcorder is plugged: Comment 24 Stefan Richter Comment 9 Stefan Richter Comment 30 Jarod Wilson If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the ‘version’ to a later Fedora version prior to Fedora 8’s end of life.

Only one instance per dvgrab run and in no particular time during the run.
firwire A timing issue is definitely a possibility — the bulk of the latency was in the packet handling routine, which might have meant the queue function was actually able to fire back up fast enough to keep enough packets queued up. Only somebody with a bus analyzer would have had a chance to see that no cycle start packets were going over the bus anymore.
– [firewire] Via VT and VT FireWire controllers unable to capture video
Grabbing performance was not consistent, though. I typically can capture for slightly longer with test-dv from libiecutils, but it usually ends up hanging as well. If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the ‘version’ to a later Fedora version prior to Fedora 8’s end of life.
Comment 16 Andy Pengelly Description Jarod Wilson Comment 15 Jarod Wilson Are we in 1. Wonder if Dan has any insight into what the two might be doing differently Since the DMA program thinks its done, no more queued packets ever get handled.
Comment 3 Stefan Richter Comment 14 Stefan Richter Coriander is not for DV, it’s for industrial cameras and a few webcams which send uncompressed video.

The Google index contains only few mentions of “isochronous cycle too long”, but that’s because kernels before 2. Thanks for fixing this – whoever you are.

Comment 7 Robin Theander I got something grabbed but the video was garbled with missing data so the image was scrolling slowly just like an old CRT loosing vertical sync. Regression in a new firewire-patch which isn’t in git yet. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

I will check that shortly. With older kernels, the controller silently stopped to initiate isochronous cycles whenever this condition occurred.
Comment 23 Robin Theander I have a few things I want to try on my Via controllers, but of course, the VT is working just fine in the box I threw it in here at home for poking over the weekend. Comment 17 Bug Zapper Seems to be something specific to your camera that we need to figure out.
