Need a legacy libs package #3

Closed dryeo closed 3 years ago

dryeo commented 4 years ago

Before updating ffmpeg-libs to 4.2.2-1.0c00 this site, https://midimusic.github.io/browsertest/index.html played MP3's fine using Firefox 45.x, after updating, playing fails. You can test in reverse order as the ffmpeg-libs package downgrades easily. The problem is that Firefox (and SeaMonkey) dynamically loads the FFmpeg libs, libavcodec53-55,57 or after dmik fixed it for OS/2 avcode-53-55,57 and it appears the new lib is avcode-58.dll. Likewise with the corresponding libavutil. As the DLLs are dynamically loaded the only symptoms are certain multimedia sites no longer working or falling back to a supported codec such as opus or vp9.

Meant avcode58.dll above. Edit seems broken.

The next ffmpeg will have it. But mind you ffox user need to install it by hand. As all ffox rpm dont trigger the automated Installation. Eventually worth a readme change or such.

OK, thanks.

Just as a side note, this is by design — FF loads these DLLs dynamically due to copyright issues. Therefore no strict dependency. It has always been like that with FF on Linux systems.

@dmik That makese sense (or rather explains why we had various users on OS2World forum reporting slightly different useage of the DLL), thank you for re-iterating this. I seem to recall that we had this discussion during the original FF45 porting efforts & testing activities too...I think...

This is done in latest rpm.
