Huh. I don't get to say this too often, but I saw a 9/11 crash.
More specifically, using Avidemux2.6_r2016_09_11_c0ce0daea3c.dmg, I see this crash after encoding:
Assert failed :0
file /Users/fx/hudson/workspace/MacOSX_EC/avidemux_core/ADM_coreVideoEncoder/src/ADM_coreVideoEncoder.cpp, line 143
This has actually happened on a couple of other builds, I think 2.6.13 and Avidemux2.6_r2016_09_08_897a70c5954.dmg. I've tried Mpeg2 (ff) and Mpeg4 ASP (ff) as the output so far, with audio output set to copy. The clip is only about a minute long, and the original is a 1280 × 720 MPEG-4 using H.264, AAC. It happens regardless of whether the cuts are on I-frames or not. Before the crash, apparently, Avidemux did actually create an output file that is playable in VLC but cannot be opened in Avidemux.
I'm running OS X 10.11.6 (El Capitan) on a 13-inch early 2011 Intel MacBook Pro with 4 GB of DDR3. My apologies if this is not the right place to report this sort of thing.
And I am sorry if this is a newbie question, but are there any stable binaries for El Capitan, or do I need to compile one myself off the 2.5 branch?
Let me know if there's anything else you need to know. I can supply the full crash details if that's helpful, but the beginning of it says this:
