bc is installed on my box
Happy for you =). But your box is not decisive and I have to rely on the worst case, namely that it does not exist
bc is a nice tool, however not on every image. I experience that recently. So to rely on bc is not a good solution, especially because there is no package in feed, so adding dependencies to install will not work.
Streamlinkproxy in standalone usage looks like an alternative to streamlinksrv so I will be comparing those two. Default port is the same 8088.
Zapping works the same, no noticeable speed difference. Unfortunately it doesn’t read streamlink configuration files and that very much limits functionality and rules out its use as an replacement at the moment. Nice error video. Some minor things like loglevel cannot be changed and playback with 4097 don’t work in cases when streamlinksrv works (youtube live is an example). I tried different boxes and result the same. 5002 is best to use here. Anyway didn’t found any advantages, maybe some specific host that I didn’t tried. I don't use E2m3u2bouquet so I can say nothing about that.
