I'm looking for a graphical editor which can allow be to cut video without reencoding. In the past I used mpegstreamclip on osx (http://www.squared5.com) but it has trouble with newer osx/retina hardware and doesn't work any more. I tried avidemux with 2.6.x and worked fine with normal h264 files, but couldn't load h265 files produced with handbrake. I tried using the latest Avidemux_2.6.11beta1_ML_64Bits_Qt5 available but still can't see graphical output.
You can see an input sample file at http://dl.dropbox.com/u/145894/t/avidemux.m4v (1.6M) and the screenshot of the program when I load the file at http://dl.dropbox.com/u/145894/t/avidemux.png. The file seems to be read correctly in terms of length and the audio plays. This sample is only 5 seconds but for longer files I can move around between intra frames. However attempting to play back from an intraframe plays just the sound for that chunk and stops, resetting the play position to zero. All of this with the blank screen with weird noise on top, at no point in time I'm able to see a valid picture.
I saw that the recent changelog for this osx version included an ffmpeg update and hoped for it to work but looks like the problem might be somewhere else. Any ideas?
It is indeed incomplete support for h265 in mp4
It should not be too difficult to do
I'll try to upload a mac test version tonight
http://avidemux.org/nightly/osx_qt5/Avidemux2.6_r2016_01_04_e8d15ff30e6.dmg
should begin to work
Indeed it does. Thanks for the build!
