Avidemux Forum

The build was from here: https://avidemux.org/nightly/osx_highsierra/

Sure.

Removing libADM_dm_ts.dylib from the "demuxers" subfolder doesn't bring anything.

Well, this was just a try. According to the log you provided, Avidemux crashed while probing the file using the MpegTS demuxer, so there might have been a chance that if the build was damaged, this damage were limited to this demuxer.

Should I try a older version?

I've just noticed that all older nightlies have been removed from the server 

Which damage do you mean?

Maybe a couple of bits flipped or such. The VM used to generate these builds is known to be not particularly stable.

This https://avidemux.org/nightly/osx/Avidemux2.6_r2015_06_10_886d36abb54.dmg works.

Well, that one is completely ancient.

If you have Homebrew and XCode installed (not sure whether the entire XCode is required, but we need at least the compiler, the linker and the headers), it should be rather easy to build Avidemux from source using the bootStrapOsx_Sierra.bash script. A most likely incomplete list of build deps includes git, cmake, yasm, qt, a52dec, faad2, xvid, x264, x265, fdk-aac and opus.

Probably a bad build? What happens if you remove libADM_dm_ts.dylib from the "demuxers" subfolder and retry to launch Avidemux and load the files? Obviously, Avidemux won't be able to load MPEG-TS files, but if the damage is limited to this plugin, the remaining part of the application should work fine.

(My Mac runs High Sierra, and official builds are generated on High Sierra too, so incompatibilities with older releases can't be rules out.)

I have installed the new version Avidemux 2.7.1 181107-09h47m_a5821f88c79.
My OS X is El Capitan 10.11.6

I can not open a videofile, Avidemux crashes then.
I have tried it with a flv and with a mp4 and a png too (the png only in order to try it, and when I try to open a pdf, it comes the correct message cannot find a demuxer)
But flv and mp4 bring to crash the app without message.

The videos are downloaded from Youtube, the flv in 2012, the mp4 in 2016.

I don't know if this problem is the same like this one in the upper thread.
But the nightly build also doesn't work.

So what can I do?
(Sorry for my bad English.)

Thank you for the kind reply.

So, it's listed in the FFmpeg documentation under "pp" - what? That was hidden real good!

Thank you for uncovering a mystery.

Recently I was able to to properly deinterlace with Avidemux about 90 minutes of old Hi8 analog video using the "Libavdec Deinterlacers, Lavcodec deinterlacer family. I used the "Cubic interpolate" option, which was the only combination which would properly deinterlace this piece of video. I am speculating that my camcorder did a poor job in cold, damp weather because most of my over 30 hours of video deinterlaces properly using yadif or bwdif. Which brings me to my question:

Looking at this web page http://www.avidemux.org/admWiki/doku.php?id=using:video_filter_libavcodec_deinterlacer which is the only documentation Avidemux supplies, there are two baffling (at least to me) references. The first is the document title:

Video filter libavcodec deinterlacer Is it "Libavdec" or is it "Libavcodec"

As we know, terminology is important and I can't find the link or proper name of the two.

Second: at the bottom of that Avidemux documentation page it says, "The best is to refer to MPlayer/FFmpeg documentation for more details." I have looked through and through both FFmpeg and MPlayer documentation and I can't find ANY reference to these particular deinterlacers!

Since the naming convention is rather loose - - maybe I am just missing the connection.
Give me a clue, please.

Thanks,
