DV acquisition doesn't work kdenlive 0.7.3 jaunty 32

[Bellegarde]

Binary package hint: kdenlive

Testing jaunty 32 bits ubuntu studio

trying to acquire video from a DV camera

after solving module/right to use raw1394,

- kino does a good acquisition...
- dvgrab in command line too...

but kdenlive 0.7.2.1 (official package in jaunty) doesn't and the latest kdenlive 0.7.3 (idem) doesn't too.

If i connected the camera, i can see the first image in the monitor, but an horrible sound is repeated, and the video doesn't move. THe only button that works is stop button and connect/disconnect (0.7.2.1) and one more, the read button which start reading (0.7.3).

By looking to terminal, i can see kdenlive is using dvgrab and ffplay commands, so i've tested them seperatly, dvgrab works :

laurent@laurent-laptop:~$ dvgrab --format dv2 exemple2
Found AV/C device with GUID 0x00008500005bd5d7
Capture Started
^C"exemple2001.avi": 52.08 MiB 360 frames timecode 00:04:57.18 date 2009.04.09 20:24:52
Capture Stopped

but with ffplay, i see only the first image and the first sound is played in cycling...

laurent@laurent-laptop:~$ ffplay -f dv -x 418 -y 217 -an exemple2001.avi

so i think the bug is coming from ffplay, but i haven't got any solution at this time.

Hope it helps...

I've received this answer from an administrator of kdenlive bug report tools :

Works fine here with Jaunty and ffplay (FFmpeg) compiled from source. So it must be something related to Ubuntu's ffplay / ffmpeg version...

Is it possible to change ffplay in jaunty ? it seems to be the trouble...

'ffplay -f dv ... some.avi' is incorrect because '-f dv' specifies raw dv, and this is an AVI.

You can try to test this with 'dvgrab - | ffplay -f dv pipe:'

I get a similar error when I try to use KDENlive.

If I run the program from a command line as sudo then I can connect to the camera. When I do this, however, the capture crashes after it is initialized and starts. This also happens with my webcam, though, and was also an issue with the webcam before I attempted a capture.

For now, a suitable workaround for some users may be to run the program as SUDO. Else, capture with KINO and then edit in KDENLive.
