Terje:

Sometimes you can read in too much.  This is specifically ONLY for unbundled builds.  Unbundled builds is meant for the purists in the O/S distro world who want to include Cinelerra-gg in their distros but do not want to include another copy of ffmpeg.  The warning is only for them to make them aware that some of the latest stuff/codecs may not be available for use in cinelerra BECAUSE they use a different version of ffmpeg.

Cin and CinX package builds on the cinelerra-gg.org website are built WITH FFMPEG 4.1 and all of the third-party packages that are known to work.  However, you do not see them (as I erroneously suggested) in a directory when you do a PACKAGE build as opposed to a TAR build.

I have the RPM binary packages installed for Leap15, which is unbundled
builds which links dynamic to the system ffmpeg and libx264
(Cinelerra10bit to libx265).

So the above is not true; if you used the package build, it is not the unbundled build.

 

Obviously the current installed system ffmpeg/libx264 (as already
pointed out ) require higher versions to support optional 'yuv422p10le'
(10-bit for Cin).

So GG just now was able to boot Leap 15 and has passed along to me how to make sure you get the 8-bit and 10-bit capabilities with X264.  Here is how:

  (1) load a small video (do not need audio)

  (2) File-> Render

  (3) choose File Format - ffmpeg and mp4 and a name for the output file

  (4) click on the wrench icon on the right side of the word VIDEO

  (5) in the Pixels text box, scroll down to yuv420p10le (the 10 stands for 10-bit)

  (6) checkmark OK

Now if you go to the Resources window, right mouse button on the highlighted media, you can choose Info and then Details to see it is pix yuv420p10le and if you do the same on your 8-bit input media you will not see 10le.

Or, knowing as how you really like mediainfo, just run that on your output media and you will see things like:

profile = High 10@L1.3 and Bit Depth = 10 bits .

You can do the same experiment with CINX.
