mp4mux creates videos with double duration and half frame rate than the original mkv file
Starting with gst 1.20, mp4mux and qtmux will the following pipeline will create a video with double the duration than the original video:
gst-launch-1.0.exe filesrc location=c:\temp\Videos\video1.mkv ! matroskademux ! h264parse ! mp4mux ! filesink location=c:\temp\Videos\video1_gst1_22.mp4
gst 1.18.4 works correctly. gst 1.20.7, 1.22.5 and 1.24 exhibit the problem above. A sample video to demonstrate the problem can be downloaded here.
This seems to happen to some .mkvs but not others. Here's a video which is converted to .mp4 correctly with all versions of gst.
