Bug - Qtractor crash at merge

What I did was add a series of Hi Hats onto an audio track for 2 bars. Hilighted the items in the track, right click -> Merge clip (not in front of my music computer right now, but I think that's how I get to Merge clip), and the cursor spins on. No response, then I have to kill it (the process that is).

Hope this makes sense.

Thanks,

Omar

re. Clip/Merge... hang, the usual and immediate question applies: is this reproducible all the time or only on specific clips?

seeya

Seems to be all the time. I tried it under AvLinux as well as Ubuntu Studio. As well as tried it on a separate set of wav clips on another track and the same thing.

I hope that helps.

and which qtractor version or build are we talking about?

Qtractor 0.5.8 under AVLinux 6.0.
On a Core 2 Duo, HP desktop 3Gb Ram.

confirmed & reproduced. while i'm taming it on the weekend, would you be kind and open the corresponding ticket, just for the records? ;)

although i had it reproduced a couple of times only... now that i try to make it once again, it just goes all the way fine, as nothing :/ and i'm still trying... :)

cheers

Done :)

Hi all,
first to say: thanks, Rui and all for qtractor and the great work you did on this!
I tried it to use it to play/mix around on selfmade music and figure out what one can do on linux music.
Finally i landed on qtractor, i have some (recorded) audio clips , made some time adjustments and want to merge the splitted regions to one new audio track/clip.
I think I have the same problem like in the autor of the first comment. After clip-merge the qtractor freezes and the processor load goes up.
I looked on sf bugtracker (https://sourceforge.net/p/qtractor/tickets/ but found no entry on this.
I tried now on 2 different systems now to get more concrete informations, and the behaviour is the same.
A minimal test: new session, and just to merge two (even empty) audio clips from a single track - same effect of freezing (the .ogg export window arises, I can give it a export file name and then it freezes at high processor load). Export-bar (percentage) stops and never completes. A part of the first clip gets exported and thats all.

Problems occured on ubuntu 12.04

I also tried to install a 0.5.12 ubuntu package from
http://qt-apps.org/content/show.php/Qtractor?content=67674
but are the .deb packages working? (they seem very small)

Finally i believe, the error depends on another library. For this i tried to to build the new 0.5.12 from the tgz, but some (required new) dev-libs are not provided in my ubuntu installation and i have to collect them from elsewhere, but i dont want to "mess up" my system with possibly conflicting libs from other providers. Is somewhere a tgz which contains all needed/used libs organized in a local folder?
Well...a lot of text. what can I do?
Thanks for reading and have a good new year!

yes, it might have been solved ,very recently though:

svn trunk rev.3709 aka. v0.5.12.2 (you can grab it from latest snapshot if you dare :)

believe it or not, the (heisen)bug was there lurking for ages, maybe ever since audio clip merge inception (ca. 2009+?)

hth.
cheers

hey, that worked! I got now:
Version: 0.5.12.2svn3710
Build: Jan 7 2014 19:05:25
VeSTige header support enabled.
LV2 Plug-in UI support disabled.

The merged clip exports as ogg, a .ogg is generated and in clip editor both parts stick together now.
Cool, thanks for that quick help.
