Because the platform chooses the Android platform. There are a number of options for playing rtmp streaming streaming media. Android
Preface
Recent projects require streaming media playback, the backend provides three kinds of streaming data (Rtsp,rtmp,hls), in different scenarios may be used in different ways to play, you need to adapt to support all streaming data playback. Spent a period of time studying, here and share with you, there are some lingering problems to see if we have a good way. RTSP Brief Introduction
This protocol stream data in front of the play, there is no particularly good solution, the need to install
Locality and causes some datanode to be relatively busier.The Equalizer is a Hadoop daemon that moves blocks from the busy DN to the relatively idle DN while persisting in the block replica placement strategy, spreading the replicas to different machines, racks.It is recommended to perform the equalizer regularly, such as daily or weekly.(1) Run the equalizer wi
In MongoDB (version 3.2.9), the distribution of data refers to splitting the collection data into chunks (chunk) and distributing them on different shards (shard). There are 2 main ways to distribute data: Balanced distribution based on the number of blocks (chunk) and directed distribution based on the Slice key range (range). The MongoDB built-in equalizer (balancer) is used to split blocks and move blocks, automatically achieving uniform distributi
the client configuration, and all access entries are changed to MONGOs;
Select the slice key to enable fragmentation.
Note: In the existing set of fragments, you need to ensure that the TAB key on the index, if not, you need to create first.
A very important component in the MongoDB fragment is called The Equalizer (balancer), which is actually played by MONGOs. The equalizer

Darwin can receive and forward RTP data. This feature is described in the official document "reflect ".Using VLC, you can easily demonstrate this function by running the following command:
vlc -vvv test.mp4 --sout "#dst=rtp{dst=127.0.0.1,port-audio=20000,port-video=20002,ttl=127,name=CHANNEL,sdp=file:///f:/channel.sdp}"
Run the preceding command to generate an SDP description file

I gave some simplified VLC Media Player Code in part 1 to show how easy it was to do and how most Wrapper libraries make a mountain out of a mole hill. in that entry, I briefly touched on using some classes to make it easier and safer to implement actual programs with this.
The first thing to do is write a wrapper for the specified tions, so that they are handled nicely in C #. for a

It's _cursor. That's what I thought before, but then I found out there was a problem, and if you just remove the mouse you can hide it, but it won't happen again unless you move out of the display area. Later found that this is the problem of LIBVLC, VLC itself also realized this mouse arrow timeout auto-hide function, you use the following command will find that VLC has a set this timeout time parameters$
