My systems run straight Debian, using an unholy combination of 'testing', 'unstable', and 'deb-multimedia'. After updating my laptop's copy of ffmpeg to v1.0, I noticed that kdenlive stopped being able to import certain clips. Checking ffmpeg's man page, I discovered that they've significantly re-worked the command line argument syntax, so it doesn't surprise me that it doesn't work.
However, now it's made me paranoid about updating any media component in my system. My desktop installation of kdenlive is still working, but there are updates to ffmpeg and MLT that are begging to be pulled over.
My current install is:
Kdenlive: 0.9.2
ffmpeg: 0.11.2
MLT: 0.8.2
There is an update for ffmpeg 1.0.1 available, but I know not to take that (yet). However, there is also an update for MLT 0.8.6 available; is it safe to take that? And when will it be safe to take ffmpeg 1.0?
