Hi !
A few news.
I could do a few test with a basic ffmpeg 3.0.1 build and found several things.
This build required me to install several dlls and freetyp6.dll why v3.0 build didn't request it when running it in line mode cmd.
I had some changes to do on AVxCAT for compatibility and more should be done in next days
(e.g. crop like croptop cropbottom and pad functions have changed since v3.0 and uses now -filter option)
Currently, I could well convert video files and saw v3.0.1 allowing a few more fps than 2.1.5 ( nice )
Curious, I tried again the v3.0 (refered as n3.0 after having changed dlls for 3.0.1 and n3.0 works now !
I search which dll was the culprit making no return into the pipe for drdialog and it is " freetype6.dll " <<
As soon my code is changed and some tests could be done, I'll post a message about next available beta build
Regards
Update: first test are promizing
