This is a part of my report. Someone would be very interested in danmu.
Danmu video site is a branch of the video sharing site. Unlike other
video sharing sites, however, comments are overlaid directly onto the video
which called ‘danmu’ or instant roast, synced to a specific playback time. This
allows comments to respond directly to events occurring in the video, in sync
with the viewer—creating a sense of a shared watching experience.
Danmu appearing on the video screen while playback ensures that all
viewers can notice them in order to achieve the interaction between the
viewers, even with expression of praise or comment the work to increase the
viewing pleasure: when many viewers intend to highlights some meaning of a
point at the same time, it will fill in a lot of reviews for the video or the
period of continuous video playback that the screen is obscured by these
subtitles, like feeling a large number of bullets blowing on the battlefield
hail.

As more danmu means more popular, this kind of social multimedia
seems to be more impactive than traditional. Your comments will also become a
part of the works, and in some works, danmu is more interesting than the works
itself. Seeing amount of danmu flying over his/her work, it is a very efficient
courage for the authors.
With Mukioplayer, an amazing WordPress plugin, almost without
programming, our group's website could support Danmu video playback and seems very similar with
Bilibili.

However, based on a large number of destructive and sheltered danmu
seriously affecting normal viewing, and it would cause a great deal of
computing pressure on the watcher’s computer CPU, in particular, the specific
time point burst danmu becomes more apparent. So there is a serious problem playback on
smartphones and tablets even the mobile clients are published. And the watch won’t pay attention
on each comment just as they are too many. So there is hardly any interaction
between two watchers through danmu. Only the watchers would notice is the
author, it is not propitious to
promote interaction between specified watchers.
During our testing, it seems that this kind of video sharing is not
very suitable for our website. As Danmu is biased in favor of the ACG class
work, such as animations original, relevant music or individual play, the
second creation, colleagues, MAD, spoof works, its application may be limited. In our website, there is not too
many videos which could attract too many Danmu because our website is biased in
health and most videos are suitable for this kind of playback.

I think danmu video is very attractive for acquaintance. And it is funny for users to sent comments on it. But there is a problem which is not easy to display the speaker. And it is not easy to control the num of the comments. and not easy to control the speaker. I think there must be some innovation to do on it to improve the user experience.
回复删除This danmu plugin has implemented perfect filter mechanism. You can filter comments by regular expression of keyword. You are even allowed to hide all danmu to watch the video without disturbance.
删除Well, I have known another two website called Acfun and Bilibili before danmu. They have similar functions to send comments while the video is playing. However, due to the technology requirement none of these website update to HTML5. I hope this could be implemented and then watch funny videos on my iPad is feasible.
回复删除There are some danmu online player clients from 3rd-parties for both Android and ios, one is. However the ios client requires jailbreak, and the limited performance of mobile devices is a big problem.
