Add SRT to GStreamer build
It would be really helpful to have SRT components (https://gstreamer.freedesktop.org/documentation/srt/srtsink.html?gi-language=c and friends) included in gst-plugins-bad just like in other distros. Building GStreamer from source is not much fun for an average Linux user...
I'm pretty sure "apk add libsrt libsrt-dev" prior to GStreamer build will suffice. That's what I see in the build log currently, and that's why SRT components are not there:
Run-time dependency srt found: NO (tried pkgconfig and cmake)
Header "srt/srt.h" has symbol "srt_startup" : NO
