I've been trying to get proxys going, but they always crash on me. Haven't the slightest idea why. I'm using Sunab's repository.

hi, can you provide a sample file causing this kind of crash.

thanks.

AVCHD 24mbs 1080p25 from a Canon camcorder. Proxys used to work in 0.7.9.

I've transcoded it into DNxHD, but I also fails to create proxys. I've also tried different project presets (Kdenlive wants me to choose 50p, dunno why) and deleting proxys all to no effect.

Hi,

What worked for me was this:

---
As a workaround, you could try to change the proxy encoding params (in Project->project settings):

replace "-f mpegts" with "-f avi" in the parameters and put "avi" as extension instead of "ts"

You may also try Sunab's svn PPA with a more updated version (although it may be unstable).

BTW: I was trying to make proxy clips out of a Canon 550D footage.

Hope this helps

Thanks for the suggestion, but it did not work, unfortunately.

Solved the problem: I had a newer version of ffmpeg installed from some removed repository. I intalles the one in the ubuntu repository and it now works fine.

@KoRnholio8 :

So it is solved.

This is time to warn (gently) users against the use of many ppas. FFmpeg evolves quickly but as a consequence APIs are broken regularly. To work with a bleeding edge ffmpeg the better solution is compiling static libs out of the system tree, like Dan's build script does.

A smarter solution would be asking some ppa maintainer (me ...) to build mlt and kdenlive packages against a static ffmpeg bleeding packages, this way other apps using regular distro ffmpeg won't be broken.

I've got ffmpeg 4:0.6.2-1ubuntu1.
