Re: [mythtv-users] DV Recording via IEEE-1394 Firewire with MythTV
If I understand this correctly, then another application would be to capture over firewire using my Canopus analog/digital converter. -buddy On Mon, 2005-03-07 at 08:47 -0800, Jon Eklund wrote: > On Saturday, March 05, 2005, at 04:08PM, Ian Forde <[EMAIL PROTECTED]> wrote: > > >As far as editing goes, that's an entirely different story.

Re: [mythtv-users] DV Recording via IEEE-1394 Firewire with MythTV
Thanks for the link to the searchable db for the list. I went back thru 2 months via text on the user side to see anything on IEEE-1394 and did not find what I was looking for. I did not check the DV streams threads. So MythTV IEEE-1394(firewire) uses Mpeg-2 TS streams using HD protocols for recording and playback. So the rawDV(or variants) file from a camcorder can not be seen by the recorder or by the player. Thanks Tom for the thread and the link.

It > was a question, still unanswered. My advice? Here's what happened to get firewire supported in myth. 1. A number of people were interested in it, some promising to test to write something up. 2. Time passed by. 3. I decided it would be nice for me to be able to do firewire HDTV recording (since I live in an apartment, I can't put in a 6' HD antenna), so I posted to the mythtv lists about steps I was planning to take to get it to a point where it would possibly be feasible. Things didn't go very well. 4. I went over to avsforum and tried to get test captures working outside of myth. 5. I corresponded with the good folks over on the linux1394 list. 6. I learned that libiec61883 is the future of firewire capture on Linux, but it hadn't been released yet. 7. I volunteered to be a tester for said library, reporting bugs back to the main developer for the library. Dan Dennedy get all of the credit here. 8. After libiec61883 was in a good place for me (read that is in: working), I posted back to the 1394 and mythtv lists 9. I received an email from someone stating that they would take a stab at writing firewire capture based on the libiec61883 test code. Jim Westfall gets all of the credit here. 10. I, along with possible others, tested the patch to myth 11. Jim submits the patch to myth and it gets accepted. 12. Everybody's happy. By the same token, the big DVB patch that went in a while back was a massive, planned *collaboration*. Moral of the story? Get it working in Linux, figure out how different it is from existing methods, then attempt a groundswell in the community. > Can or does MythTV record DV via the newly supported IEEE-1394(firewire) > port?

Get it working with libiec61883 or some other standard linux firewire library. At this point, it may be possible to integrate it as a tuner type into mythbackend. As far as editing goes, that's an entirely different story. Or maybe not. Once you've got video into myth, you can cut with the commercial editor, but as far as full editing goes, that's probably suited to a full-blown plugin.
