[Bug 1066558] [NEW] .MTS video does not play in Openshot 1.4.3, some errors reported after running in shell

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I like Openshot, I think it has a great design, thanks to Jonathan. But I have never been able to use it, because I have an AVC/HD camera, a complicated video format, even for the proprietary windows software included with the camera.
In previous versions I could play inefficiently .MTS files, but in the present version 1.4.3 the screen shows white, and the soun stops every second. (I includded a screenshot attachment).
The program crashes frequently.  Recently I reinstalled Openshot in this computer:

$ uname -a

Here is the version of melt

$ melt --version
MLT melt 0.5.4

Openshot was installed copying the ppa lines in openshot page, to bash, then sudo apt-get install openshot
As far as I know, I did not installed melt alone, It maybe was installed as a dependency when Openshot was installed.

It seems that the problem is the melt version, because I can't neither
play .MTS videos with  $ melt file.MTS

Unfortunately Ubuntu freezes the last version of each application in
each distribution. It could be the source of the problem, because apt-
get does not install the newest melt version.

It seems that Jonathan owns a Canon HD camera which records the same
video format that has been shown problematic with Openshot and other
applications in my system.

I hope this helps to improve Openshot.
