I downloaded a 1080p video stream from youtube. When I open it in Avidemux, it crashes.

This is on a freshly downloaded version 2.7.5 200207_27b419866ec-fflibs 4.2.2, Windows 10.

I'll attach the first 100KB of the file. I hope that's enough to diagnose the problem.


As suspected, the crash is the result of support for AV1 implemented and enabled in the demuxer and in other relevant parts of the chain, but the required libaom library not installed and the decoder thus not enabled and not built in the official MXE build node where MinGW Avidemux builds are generated. Not sure I can do anything about it.

Recent official VC++ builds have the decoder plugin available and working.


The crash as such if a video decoder for a particular codec is unavailable should not happen anymore starting with r200214 from
