output of PITIVI_DEBUG=*:5  GST_DEBUG=3,python:5,gnl*:5 /usr/bin/pitivi  openings.xptv

There's a duplicate of this bug on launchpad: https://bugs.launchpad.net/ubuntu/+source/pitivi/+bug/882790, where it's in the "confirmed" status.

I'm seeing exactly the same thing trying to render four slightly overlapping webm files with a single normalised and denoised wav file. 

The bug is consistently reproducible with this project. I'd like to make the project available to you so you can debug pitivi as it attempts to render the project. It's 428Mb, so I'll arrange to share it with you via Dropbox if you like.

Hi I'm seeing the same with 2 slightly overlapping tracks from mp4 source. Actually coming from my n900.
This is annoying since I thought the task is finished and at then it refuses to work at the last step.
My System:
gentoo, gstreamer-0.10.35, pitivi-0.14.1

I have also tested it on latest stable Ubuntu and Pitivi. The same here.

I'll try to attach the project file.

Project file for failing rendereing

Hi folks,
You might be all experiencing the same bug, or you might be all experiencing different bugs.

Currently PiTiVi's core is being replaced by GStreamer Editing Services. This is a major overhaul and we sadly can't investigate much bugs that occur on the "traditional" core of PiTiVi.

For one thing, I'd need not just the xptv files, but associated media files too.

Ben, you mentionned being able to provide the xptv + media files through dropbox. Please make a .tar archive and mail me the link (to nekohayo at gmail). That way I can check if it happens with the GES version (and with 0.15). Thanks!

Hi Jean-François - thanks for the information, and for taking the time to look at the problem. You should have received an email from Dropbox specifying the URL at which you can collect the tarball containing media files and xptv project file which should allow you to reproduce the "infinite render" problem. If you unpack the tarball in your "Videos" directory, you'll only have to change your username in each of the file paths in the xptv file.

I ought to have told you a bit about my system:

Okay, confirming the bug regarding Ben's test project that he sent me for testing ("waysOfSeeingPitiviProject.xptv" and associated files). The bug occurs on 0.15 and pitivi GES.

However, to be perfectly honest, we are very short on developer resources right now and there is no immediate fix for this. Someone needs to come up and do the proper debugging and bug fixing work in GES (or in gstreamer if the problem is in gstreamer).

Hi - can someone with the appropriate rights change the summary of this bug report. It ought to be "Render never completes".

hmmm, any news, guys? I just run through Pitivi 0.15.2 and the problem occours also here. ...pitty that it's right on the last step.
I think I'm gonna take that video with some screencapture program for taking videos, because the playback works normal, just the render fails on any chosen codec...

FWIW, i was facing the same non-linked issue and pitivi hanging on "Estimating..."... i removed 0.15.1 and installed 0.15.2 rpm, and removed libdirac rpm (The troubleshooting page of pitivi says its not compatible).

After this.. i am able to render now. I am on F17 x86_64 desktop.

thanx,
deepak

Hi there,

As Pitivi 0.91 has now been released, we would like to encourage you to test it.

It is quite possible that your issue is fixed in this version,
as it is a very significant technical overhaul compared to the 0.15 series.
Read more about the 0.91 release here: http://wiki.pitivi.org/wiki/0.91

If you can reproduce this bug against 0.91 or newer (such as the git version),
please update this bug report accordingly with detailed instructions to
reproduce the bug, updated sample files/projects in xges format, etc.

Drop by our IRC channel if you need help getting started or want to help out!

Thanks!

Closing this bug report as no further information has been provided.
Please feel free to reopen if the issue persists with 0.94 or newer
and if you can provide the information asked for. Thanks!
