[kirby]

I am using avidemux 2.6.13-1 on fc24. When I try to save a image using x264, mp3(lame), and mp4v2 i get an error that says that Muxer cannot open. the console looks like

Save image? Can you enlighten this? Workflow?
Avidemux has issues opening your source (loading video or image). Normally mp4 container with mp3 audio should work.

The initial error

Code Select Expand

  [encode]  [x264] Error encoding -1

comes presumably from libx264 in your Fedora 24 installation, not from Avidemux. The MP4v2 muxer not receiving any video data to mux is merely a victim.

I am using avidemux 2.6.13-1 on fc24.

Plain and simple: don't use 2.6.13. Please use the current git. If this is not possible, use the latest release 2.6.14 (build it yourself; once 2.6.15 is out I'll beseech rpmfusion maintainers to update the currently distributed 2.6.12 to 2.6.15 ASAP).

Apart from this, please describe your goal, not your steps.

I want to trim and put fades at the beginning and in of a recording made on a Flip in preparation for upload to YouTube. I assumed, possibly erroneously, that since I was able to view and edit the video that avidemux was passing stuff to the output just fine. I chose those codecs and mux because that was working for me before I changed machines. Looking at the backup from the old machine, the executable was named avidemux3_qt4.

[eumagga0x2a]

This means, you want to reencode a video with a few filters applied (no images). The Avidemux 2.6.12 Qt4 build distributed by rpmfusion.org may be a better choice than 2.6.13 anyway, but I would still recommend the current git or the latest release.

[kirby]

Well said! 2.6.14 does a fine job with the video although I am now just getting a buzzin when I play back the original. I am in the process of encoding and will know if things work shortly. Kudos to the author of bootStrap.bash. Would that everything I try to build went that easily.

Followup: Video worked perfectly. Audio is nothing but a buzz. I will install try to see if I can get it to build with different codecs and if the rabbit hole gets too deep, I will install the 2.6.12 version from rpmfusion.

Thanks!
