I got crunchyroll to work on my computer using quickstreamer and livestreamer, my videoplayer is MPC-HC. Here is a video of it working: https://my.mixtape.moe/ylnpxg.mp4
After you fully install both quickstreamer and live streamer you need to edit some configs in the livestreamer app data folder. (Credit to dlr5668)
Open the run dialog by pressing the windows key and r at the same time, type in %appdata% then hit enter. Find a folder called livestreamer and open it, inside will be a few files. Open the one called livestreamerrc with your favorite text editor. Then paste this in:
# MPlayer2
player=C:\Program Files (x86)\SVP 4\mpv64\mpv.exe
# Use this if you want to transport the stream to the player via a named pipe.
#player-fifo
# Use this if you want to transport the stream to the player via HTTP.
#player-http
# Use this if you want Livestreamer to only pass a URL to your player and
# let it handle the transport of the stream itself.
player-passthrough=http,hls,rtmp
# By default Livestreamer will close the player when stream is over.
# Use this option to let the player stay or close itself instead.
#player-no-close
# Use this option if you want Livestreamer to keep trying to access
# the stream even if it goes offline or disconnects. Your player must
# support HTTP and its playlist should be set to repeat mode.
#player-continuous-http
# Show console output from the video player
#verbose-player
# RTMP streams are downloaded using rtmpdump. Full path to the rtmpdump exe
# should be specified here.
rtmpdump=C:\Program Files (x86)\Livestreamer\rtmpdump\rtmpdump.exe
# Log level, default is info
#loglevel=debug
# Number of threads to use when streaming HLS streams
hls-segment-threads=3
# Number of threads to use when streaming HDS streams
#hds-segment-threads=1
Hashtag the mpv line and then point the mpc-hc line to your mpc-hc executable. But we are still not done! We need to install a library via the mpc-hc maintenance tool, I don't remember which one you need to install exactly so i'll just post what i have installed: http://prntscr.com/bxkatx http://prntscr.com/bxkazq. Should be smooth sailing from there. Enjoy!
