| Description | If the MLT installation hasn't the avformat module the config wizard makes you think that you can still work with DV files.
The thing is that if you don't have it installed the "audiocodecs", "videocodecs" and "supportedformats" variables are never filled in the configuration. Then in renderwidget.cpp, before checking the formats support for the different profiles, you find things like "if (!formatsList.isEmpty())". Since formatsList is empty, no check at all is done. You can actually try to render a file to H.264... but it obviously fail.
But the problem is that the "Raw DV" profiles also need of the avformat module. Making kdenlive totally unusable if you don't have the avformat module.
I don't know the details of melt working. But notice that in profiles.xml it says: "<group name="Raw DV" renderer="avformat" type="av" extension="dv">". Why is renderer="avformat"?
Then you find things like:
"<profile name="DV PAL 4:3" standard="PAL" args="f=dv pix_fmt=yuv420p s=720x576 mlt_profile=dv_pal" />"
Since it says "f=dv", if the format detection actually worked, it would be detected as unsupported.
