Ripping from dvd doesn't work

[David Prieto]

Hi,

Just tried to rip a dvd using Arista 0.8. I selected the source (dvd), device (computer) and preset (high), then pressed "add to queue", but nothing happened.

This happens every time I try.

Make sure you have the required GStreamer plugins installed! See the README for what all is required.

Please run arista-gtk in a terminal and paste the output into this bug report. Even more helpful would be to try the latest trunk with:

bzr export arista lp:arista

And using the latest trunk run ./arista-gtk -v and paste the output here!

Another note - ripping from DVDs requires libdvdcss to be installed if the DVD is encrypted with CSS (most commercial DVDs are). It is usually not in the normal repositories but can be found in various places online because of the potentially illegal nature of decrypting DVDs to watch or rip them.

I just checked, and all dependecies are met (python-gtk is 2.14 though). Libdvdcss is there too.

Running arista-gtk from a terminal, then trying to rip a dvd gives this output:

libdvdread: Using libdvdcss version 1.2.10 for DVD access

[Daniel G. Taylor (danielgtaylor)]

I believe this was due to a bug with dynamic elements not linking properly which has now been fixed in the latest release with help from the GStreamer developers. Please try Arista 0.9 and let me know if this issue still exists!

[David Prieto (frandavid100-gmail)]

0.9 does generate a video file, but it seems to be empty and is created in ~1 second. I'm attaching the resulting video.

[Daniel G. Taylor (danielgtaylor)]

Quite strange. Can you confirm that this happens with all DVDs? I was able to rip a DVD today with Arista (the first Futurama movie) without any problems. Perhaps it is the disc? Does it rip okay in other apps?

[Joe "Rotund" Tennies (joe-tennies)]

I'm using the 0.9.3+repack-0ubuntu3 in Karmic, and I have to "Add To Queue" twice. The first time it will typically fail with an error message that there is no audio or video (verified on 2 computers). Of course, now that I tried to quickly reproduce it, it didn't and is now ripping.

[Joe "Rotund" Tennies (joe-tennies)]

Sorry, the whole point of the comment was whether that was what was being observed.

[KarlRelton (karllinuxtest-relton)]

I'm on Karmic and it just hangs, similar to #3 but without the Gstreamer asserts.
