that's brilliant, well done. Good news is both avidemux-2.7 and avidemux-qt5 still build successfully on 10-Stable.
The only small install hiccup currently needs a "chmod g+xr /usr/local/lib/libADM6*"
annoying thing is the AudioDevice, the dummy works silently but trying to play a video with either OSS/PulseAudio causes a
A52_block failed! on fblock message and crash.
