[Bug 1130920] Re: audio glitches when trying to play

 

I was able to reproduce it on a different machine with Ubuntu 12.04

First, I tried to install openshot from repositories.
It was openshot 1.4.0-1ubuntu1, and mlt:
$ dpkg -l |grep mlt
ii  libmlt++3                              0.7.6+git20120204-2                                  MLT multimedia framework C++ wrapper (runtime)
ii  libmlt-data                            0.7.6+git20120204-2                                  multimedia framework (data)
ii  libmlt4                                0.7.6+git20120204-2                                  multimedia framework (runtime)
ii  python-mlt3                            0.7.6+git20120204-2                                  multimedia framework (python bindings)

Then added MLT and openshot PPAs, now versions are:
$ dpkg -l |grep mlt
ii  libmlt++3                              0.8.8-0ubuntu0~sunab~precise1                        MLT multimedia framework C++ wrapper (runtime)
ii  libmlt-data                            0.8.8-0ubuntu0~sunab~precise1                        multimedia framework (data)
rc  libmlt4                                0.7.6+git20120204-2                                  multimedia framework (runtime)
ii  libmlt5                                0.8.8-0ubuntu0~sunab~precise1                        multimedia framework (runtime)
ii  python-mlt5                            0.8.8-0ubuntu0~sunab~precise1                        multimedia framework (python bindings)
$ dpkg -l |grep openshot
ii  openshot                               1.4.3-1                                              Create and edit videos and movies

And bug exists! I hear audio glitches again! What I did I just created a
new project, then added my AVI file, cut it into 2 pieces, and then put
second piece onto the second track and slightly overlapped 2 tracks.
Then clicked Play - and audio glitches were here!

If it still doesn't help, will it help if I try to create a VirtualBox
virtual machine, reproduce the issue, take a snapshot and place it
somewhere?
