RDEPEND should have media-video/ffmpeg and media-video/libav with USE="vpx" also, or WebM format will not work. Reproducible: Always
What is the concrete error do you get? Thanks
Created attachment 414654 [details] Screenshot that show the issue. This is not an error, but warning during program execution that WebM can't be used (screenshot attached), and, yes, WebM can't be used without USE="vpx" for ffmpeg package.
I am unsure if this runtime only dep should be added to openshot, I mean, if people don't want this format or they want it, they should toggle it in the ffmpeg package ... but why force it to be on for everybody if people won't use that format?
I am just asking about USE="vpx" flag for openshot, so people will see disabled feature and can decide by yourself need them WebM or not. And, if WebM them need, portage will route them to ffmpeg/libav and "vpx" flag, as it should be imho. But for now we have situation "guess which package have exactly same libvpx what openshot need for WebM" or "where should I find libavformat-extra package or something for Gentoo to make it work"...
Created attachment 426134 [details, diff] openshot-1.4.3-ffmpeg_vpx_not_theora.patch While I agree with Pacho about the "force it to be on for everybody" bit, unfortunately this is what the current OpenShot ebuild already does for other formats we so might as well add USE=vpx to the list... or even better, given Theora never really took off and it was VP8 who made it into WebM instead, have USE=vpx replace USE=theora. Please find attached a patch which takes care of that. That said, OpenShot-2.0 has reached its third beta version and I have begun looking into writing an ebuild for it. Given it will be quite different from that of the 1.4 branch, I believe it will be a good opportunity to improve the way of handling ffmpeg/libav USE flags as well.
