--- Comment #2 from Jonathan Gilbert <c6kargn...@liamekaens.com> --- Turns out that "f=mkv" really is missing from the list that MLT passes back when queried. The fact that the error goes away when editing the profile is the real bug, described in #414814, and it is a secret "feature" of FFmpeg that if you ignore it and say "f=mkv" _anyway_, then it proceeds as though you had used the actual, supported format name, which is "f=matroska". So, the bug as reported here is not actually a bug, and the real bug is accurately described in #414814. -- You are receiving this mail because: You are watching all bug changes.
