The naming scheme has changed
It's avidemux_amd64_date_buildNumber.app
e.g. version 21
http://avidemux.org/nightly/appImage/avidemuxUniversal_amd64_160814_21.app
download it,
chmod +x avidemuxUniversal_amd64_160814_21.ap
then just ./avidemuxUniversal_amd64_160814_21.app or double click on it
What works :
- Reading, encoding, most filters & codec
- Tested on ubuntu, Fedora, Debian all 64 bits
What does not work:
- libva hw accel
- avsfilters
- command line arguments
The _23 versions fixes the command line call and libva usage with nvidia
It might work with intel GPU, not sure
