Hello,

that's my first post here - perhaps you're able to help me...
kdenlive 17.08.2
libmlt 6.4.1-13.2
openSUSE 42.2

I've been using OpenSuse Linux since 2000, and used Kdenlive for editing some small digitized old Super8 movies.
Now my son got a GoPro and data increased tremendously Very fast I found the Proxy Clip option and created a new profile with following settings (taken from http://thediveo.blogspot.de/2013/10/eff ... n-27k.html):
-f mpegts -acodec libmp3lame -ac 2 -ab 128k -ar 48000 -vcodec mpeg2video -g 5 -deinterlace -s 1080x720 -vb 4000k

Whenever I add clip to the project, I get the message, that the Proxy Clip can't be generated (I've a German locale, so it says: "Proxy Clip kann nicht erstellt werden").

When using the same ffmpeg options on the command line, extended with -i <input.mp4> and the output filename, ffmpeg converts the file correctly.

The clip's metadata from ffmpeg:
Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 45382 kb/s, 59.94 fps, 59.94 tbr, 60k tbn, 119.88 tbc (default)
Duration about 20 sec, ~112MB

I tried the pre-installed proxy settings, but both of them failed, too.
I searched a lot, but it seems this seems to be a rare problem. Creating proxy clips should be rather easy... Any hint?

Thanks and regards,
Chris

Hello,

no idea? N hint for further debugging?
When starting from command line I see the following:

Code: Select all

> kdenlive
QXcbConnection: XCB error: 8 (BadMatch), sequence: 5008, resource id: 134217998, major code: 154 (Unknown), minor code: 11
QXcbConnection: XCB error: 8 (BadMatch), sequence: 15190, resource id: 134218121, major code: 130 (Unknown), minor code: 3
QXcbConnection: XCB error: 8 (BadMatch), sequence: 15216, resource id: 134218121, major code: 130 (Unknown), minor code: 3
[swscaler @ 0x7fc6c8645420] Warning: data is not aligned! This can lead to a speedloss


The XCB errors occur while starting kdenlive and moving the cursor into the poject-bin. The swscaler warning appears when importing a clip. I haven't found any usefull to these messages...

Meanwhile I tried some other video editing software, but I'd really like to keep on using kdenlive.

Hello,

problem solved, my fault.
Just for the docu:

In Settings > Configure Kdenlive > Environment I defined the ffmpeg path with "/usr/bin" only, not the complete "/usr/bin/ffmpeg".
Having done this, and checked the same for melt, proxy clip creation works fine.


Regards,
Chris
