• mpv Media Player, a fork of MPlayer with features Biligrab-Danmaku2ASS requires

Example

./bilidan.py http://www.bilibili.com/video/av899574/
./bilidan.py http://www.bilibili.com/video/av314/     # High density comments!
./bilidan.py http://www.bilibili.com/video/av332732/index_7.html # Extreme density!
./bilidan.py http://www.bilibili.com/video/av297197/  # Even Toukome (advanced comments)!

Use option --source overseas if your are outside China. And --source html5 to use the the experimental HTML5 API. Use --fakeip if you can't get valid media URLs due to ip restrictions.

Why Biligrab-Danmaku2ASS?

• Bilibili uses a Flash-based video player. Flash is unavailable since Chromium 35 to Linux users.
• Chrome Pepper Flash has a font-related bug on Linux, which causes the whole page crash when Flash tries to render certain CJK fonts so that you have no chance to switch to another font. This caused Bilibili Flash player unusable to Google Chrome users on Linux.
• Mozilla Firefox users on Linux never receives a newer Flash player than 11.2 from Adobe. It is certain that Adobe has abandoned Flash.
• Flash consumes too much energy. Flash causes a burning laptop.
• Experiments show that Danmaku2ASS renders a lot faster than the native Bilibili player and even similar software such as ABPlayerHTML5. Thanks to libass, Danmaku2ASS has passed a extreme density test at 60 fps on a Intel Core i5 laptop.

Tips

• Use key V to switch comment visibility.
• Some videos require logging in your account. Import your Cookie at bilibili.tv with --cookie option.
• If you have difficulties connecting to video server, try --overseas.
• If your computer is not fast enough, try --mpvflags '--framedrop yes'.
• Use --d2aflags 'duration_marquee=5' to set comment flow speed.
• Use --d2aflags 'text_opacity=0.8' to set comment opacity.
• Try to fast forward or rewind when streaming is stuck, or to tweak cache parameters of mpv.
• For issue related to URL parsing (especially the experimental HTML5 API), please report directly to Biligrab, the upstream parser: https://github.com/cnbeining/Biligrab/issues
