been a while since i've set it up but i'm pretty sure that there's two transcoding presets on the server that will always transcode your stream no matter what, so trying to increase the quality client wise will result in no increase in quality and higher values are probably just choking the server
regarding passthrough mode, this is where the server won't touch your stream at all and the stream will be just passed through, however it is important that you actually stream in a codec/container/profile combination that is actually supported by browsers, which is a pretty limited list
a safe bet would probably be to test with something like h264 baseline profile and go from there
i'm gonna try it out this weekend but i'm pretty sure that i already confirmed that as long as a html compatible video stream is outputted from your streaming client passthrough will work
