Description steer 2016-04-07 19:21:58 UTC

I recently updated my OpenSuse version to leap 42.1 and my kdenlive project which is ok under Suse 12.3  now display "INVALID" over a black background for all parts issued from a .VOB file
The part coming from .mp4 files are still ok.

I started a new project and when I tried to add a clip from a VTS_01_1.VOB file I got an error message saying the "clip is invalid and will be removed"

my current kdenlive version is 15.1.3 
The melt version is 0.9.8.  
melt test_file.kdenlive  runs well
but melt VTS_01_1.VOB   fails

The ffmpeg version is 3.0.1, ffplay VTS_01_1.VOB    displays the video without any problem

Reproducible: Always

Steps to Reproduce:
1. open a new kdenlive project
2. add a clip from a .VOB file (I do not know how to attach it to the report) 
3.

Actual Results:  
An error message
"clip is invalid and will be removed"

Expected Results:  
display the clip in the clip monitor

Created attachment 98281 [details]
A  small .VOB file which creates the problem

To reproduce the problem, try to add the attached clip

This is an MLT issue. I can confirm that with current MLT's git (6.0.1), the clip does not play, we just get black frames. The problem seems to be that your VOB file contains DVD navigation and subtiltle streams.

Remuxing the clip with the following command fixes the issue:

ffmpeg -i VTS_01_1.VOB -acodec copy -vcodec copy fixed.vob

"The problem seems to be that your VOB file contains DVD navigation and subtiltle streams."

The VOB file i attached effectively contains DVD navigation and subtiltle streams, but I take it because it is small enough

I try the instruction 
ffmpeg -i VTS_01_1.VOB -acodec copy -vcodec copy fixed.vob

But I am still unable to add fixed.vob as a new clip in a new project ("clip is invalid and will be removed")

ffplay fixed.vob displays the video
melt fixed.vob  says:Failed to load "fixed.vob"

may I attach my VTS_01_1.VOB which is 1Go ?
