[FFmpeg-user] Libraries missing?

Hi there, Moritz.
I did read the entire thread, and I see that transcoding the file works for
her, but the solution seemed overly complex. Simply renaming the file seems
much simpler and less error prone.
This lady wants to edit the video in Kdenlive, and Kdenlive is able to edit
the video directly without a transcoding step.
The issue is that Kdenlive trusts the OS to pass the correct mimetype to it
for any file it tries to open.
So it does not open the .MOD file as a video, even when ignoring the
extentions. There does not seem to be a way around this.
Interestingly enough this would hint that I could use .MOD (the proper
ones) as backing audio for video. Changing the extention changes the
detected mimetipe in KDE. I doubt that this is something the the KDE devs
are going to change.
As I said, in her case the most simple thing to do would be to rename the
video to have a .mpg extention.
Then Kdenlive tries to open it as a video, and does the right thing from
then on. It even works when there is no extention to the file, as then it
uses the unix way and actually looks inside the file, but this does
introduce an extra step in the lady's workflow, as files with no extention
is not automatically detected as video files, and filtered out.
This course of action avoids the quality loss that comes with a transcode,
as well as the time element.
I agree that this is rather hackish, and completely off topic for an ffmpeg
thread, but it does solve the original poster's original problem.
