[Coriander-user] "(dc1394_capture.c:466) error!" on Receive

[dmendels <den...@ya...>]

"(dc1394_capture.c:466) error!"

I'm getting the above error, with Ubuntu Hardy (Coriander 1.0.1-3.2build1;
libdc1394-13 1.1.0-5ubuntu1), when I try to "Receive" data, using the
RAW1394 method, from a Unibrain Fire-i 1.2 camera. This function used to
work for me at some point in Ubuntu Gutsy - not sure when it started failing
(presumably the Hardy upgrade). 

Please advise.

 - Dennis

The raw1394 iso receive interface which libdc1394 v1 may use has been 
removed from the kernel since Linux 2.6.23.

This kernel interface has been superseded by the more efficient 
interfaces provided by video1394 and raw1394 (its 2nd one, called rawiso).

You're suggesting that when I install Coriander in Hardy via a package
manager, the dependencies that get automatically installed during that
process are insufficient to allow use of Coriander?

If that is the case, then it would be good if Coriander dev would fix the
dependency list.

I don't know the older versions of coriander, but can't you switch it to 
video1394 mode?  (So far I have only occasionally used one or two 
coriander pre-releases which were libdc1394 v2 based.  Libdc1394 v2 does 
not use the old 1st generation iso interface anymore.)

Package dependencies won't help much here.  No distributor would 
maintain alternative older kernel packages just to support all of 
libdc1394 v1's modes of operation.  BTW, if a package has incorrect 
dependencies, that's something to be fixed by the one who created the 
package.  That's almost always not the one who developed the program 
provided by that package.

That works - thank you!

The only small glitch was that I had to override the default VIDEO1394
device (/dev/video1394) to /dev/video1394/0.
