Description Ben Beasley 2022-02-25 15:43:53 UTC

Description of problem:

I have a package (https://src.fedoraproject.org/rpms/fasttrack), which in its latest upstream version strongly favors the FFMPEG backend for OpenCV.

Now that a stripped-down/legally unencumbered version of FFMPEG is packaged as ffmpeg-free (https://src.fedoraproject.org/rpms/ffmpeg), is there any reason not to build OpenCV with FFMPEG support in Fedora?

Version-Release number of selected component (if applicable): 4.5.5-5

Comment 1 Ben Beasley 2022-02-25 15:44:12 UTC

I tried doing a test build and encountered a few issues, but I wanted to wait for input on the basic idea before investing effort in trying to solve them.

(and a few more)

Comment 2 Nicolas Chauvet (kwizart) 2022-02-25 16:14:17 UTC

I'm personally not supportive about ffmpeg-free in fedora at all.

I might revisit this later if ever this is a "glitch free" experience.


For now I recommend to keep using the gstreamer backend.

Comment 3 Ben Beasley 2022-02-25 16:18:52 UTC

Thanks for your feedback! Shall I leave this open, or close as WONTFIX?

Comment 4 Nicolas Chauvet (kwizart) 2022-02-25 16:24:38 UTC

You can close at WONTFIX.

At least, if you want to have a copr testing ffmpeg-free, feel free. The major issue is to see how it goes when some expected codecs aren't available. This requires a heavy testing. (and even to maintain test load for any future releases).
