Hi,
Following Kdenlive's bug report:
https://bugs.kde.org/show_bug.cgi?id=392294
I noticed that encoding to webm with the avformat consumer produces
files reporting an incorrect fps (1000fps). Some googling suggested to
enforce the fps on the stream, and the following patch produces files
that report a correct fps. However not sure if this can have side effects...
Any comments on that ?
Regards
jb
