| stochastic | Hey everyone, who in here is currently running a firewire audio device? | 05:10 |
|---|---|---|
| ailo | stochastic, I have one | 05:27 |
| ailo | focusrite sapphire pro 40 | 05:27 |
| ailo | Works fantastic on Oneiric with a -lowlatency kernel | 05:28 |
| ailo | I had to recompile my own. Going to see if I can put it up on my PPA later | 05:28 |
| stochastic | ailo, it's been a while since I've had a working firewire-enabled computer and I'm trying to get my presonus firepod working on my new laptop | 05:33 |
| stochastic | what steps are needed to get things rolling out the gate? | 05:33 |
| stochastic | 11.10 install - fresh | 05:33 |
| ailo | stochastic, Since 11.04 firewire cards work out of the box | 05:33 |
| ailo | You only need to be a member of audio group in order to run jack | 05:34 |
| stochastic | okay, well I get nothing but crashes over here | 05:34 |
| ailo | One thing I had to do to get mine working was having to have the card on while I stuck in the cord | 05:34 |
| stochastic | is jack set to 'realtime'? | 05:34 |
| ailo | Just use standard jack settings | 05:35 |
| stochastic | I always boot up with the device on and plugged in | 05:35 |
| ailo | Now, mine is behaving differently for some reason, so I can get it working by first injecting the cord, and then turning the device on | 05:35 |
| stochastic | hey what do you know, unchecking 'realtime' in jack set it up fine, now to run some audio tests | 05:36 |
| ailo | Ok, then you were not a member of audio group? | 05:37 |
| stochastic | yes, I was a member of the audio group | 05:39 |
| stochastic | I did remember that step in earlier config tests | 05:39 |
| ailo | stochastic, Did you logout login? Cause, that would be the only thing I can think of why realtime would not work. | 05:41 |
| ailo | stochastic, Here's why your device works out of the box "/lib/udev/rules.d/60-ffado.rules" | 05:42 |
| ailo | So, you don't need to set any rights for the firewire device itself | 05:42 |
| ailo | However, in order to get jack to run it in realtime, you need to be in audio group | 05:42 |
| ailo | If you want to double check, just run jack as root | 05:42 |
| ailo | stochastic, So, in short, to get a firewire device working, generally the only thing you need to consider is being a member of audio group | 05:44 |
| stochastic | ailo, well I have the card hooked up, trying to record into an ardour session but the track won't record (nor will the ardour transport start - or the jack transport for that matter) any suggestions? I also see no levels in the ardour track inputs. | 05:48 |
| ailo | stochastic, I would double check with the onboard card, and if all else fails, try the firewire device with OSX or Windows | 05:55 |
| ailo | I mean, double check that everything works fine with alsa, and the onboard card | 05:55 |
| ailo | Don't have any specific knowledge about your device | 05:56 |
| ailo | I would also make sure it works in realtime, which is kind of essential I believe in order to get any kind of good performance | 05:57 |
| ailo | stochastic, Good luck. Gotta go now :) | 05:58 |
| intenzo | hi! | 06:56 |
| intenzo | does anyone here know it its possible to start a capture at a specific smpte time in dvgrab? | 06:56 |
| holstein | anything is possible, but i would probably try and 'do it in post' | 06:57 |
| intenzo | do it in post? | 06:58 |
| holstein | yeah | 06:58 |
| holstein | grab, edit afterward | 06:58 |
| intenzo | ah | 06:58 |
| intenzo | well i got 4000 dv tapes to copy so i realy need to automate | 06:58 |
| intenzo | ;) | 06:59 |
| holstein | whats the issue? | 06:59 |
| holstein | you'll need to set the grab times per tape then | 06:59 |
| intenzo | theres 2min of colorbars and black picture in the beginning of every tape | 07:00 |
| holstein | i still think any editing would be easier than anything during capture | 07:00 |
| intenzo | for some reason i can set the end time but not the start time | 07:01 |
| intenzo | just thought that was wierd and was afriad i had missed something in dvgrab | 07:01 |
| holstein | not sure | 07:01 |
| holstein | im not sure who's maintaining that package | 07:01 |
| intenzo | do you know any alternatives to dvgrab? | 07:02 |
| holstein | not sure who would know either | 07:02 |
| holstein | not a lot of video folks here unfortunately | 07:02 |
| holstein | and what i do , i just edit | 07:02 |
| intenzo | think I'll have a look on the dvgrab code to see if I can do something clever | 07:07 |
| intenzo | thanks! | 07:08 |
| holstein | intenzo: good luck | 07:08 |
| holstein | intenzo: feel free to comment on the mailing list | 07:09 |
| holstein | i see some video chatter there sometimes | 07:09 |
| holstein | VERY rare in this channel though... | 07:09 |
| intenzo | well it was a long shot, but thought that some here would have some knowlige about it | 07:10 |
| intenzo | i'll get back if i find a good solution | 07:11 |
| intenzo | holstein: I solved it | 14:31 |
| intenzo | a fried made a custom build of dvgrab ;) | 14:31 |
| intenzo | it adds a startcapture option | 14:31 |
| intenzo | https://launchpad.net/~rawler/+archive/ppa | 14:32 |
| holstein | intenzo: w0w | 14:46 |
| holstein | sometimes i tell people the software is open, and they technically can make it do anything | 14:46 |
| holstein | rarely does someone actually do it though :) | 14:47 |
| intenzo | hes f_ing great | 14:47 |
| intenzo | also, it was a rather easy patch so all other functionality is there and should work as espected | 14:49 |
