This time, the work of the need, on the rtmp to do the FLV stream to the standard H264, AAC conversion, the server is open source project Crtmpserver, client flex writing, Video coding H264, Audio coding AAC, now some of the agreements related to the following things record.
I. Analysis of FLV data
Let's take an FLV file to briefly analyze the format of the FLV data

If we want to encapsulate Speex encoding into rtmp or FLV, we may encounter problems with how to populate Audiotagheader, Speex encoding supports 8k,16k,32k sample rate, but only 16k in rtmp or FLV protocol, At this point the sampling rate needs to be treated as 11.025k, that is, the packet of this byte is 0xb6
For the AAC encoding in RTMP or FLV packets, AAC sa

RTMP is real time Messaging Protocol (Realtime Message Transfer Protocol), Rtmpdump encapsulates some of the RTMP protocol interfaces, making it easier for users to use the RTMP protocol. For the use of rtmpdump, you can refer to the blog
Linux system Rtmpdump (LIBRTMP) publishes H264 data via rtmp

RTMP is designed for transport network streaming, requires support from servers such as Fms,awaza, and provides better copyright protection for streaming media content, and it also needs to pay royalties to adobe itself.
First, the two work differently:
RTMP data requires a dedicated server to receive, such as FMS, Awazal, etc., and then play through the local Flash player.
The HTTP protocol can transf

to real-time requirements are very high, such as 0.5s or less, this is a good choice. The former mimic Spydroid wrote a proposed RTSP server, in fact, is options,describe,setup,play,pause,teardown these steps, the agreement with the most extensive, on-line introduction is more. To really understand the RTSP protocol, the C + + language is good to see live555.RTMP protocol, own recent research, if interested, can look at my other articles.RELATED Link

Adboe's red5 Streaming Media Server is free and open-source. It can be used with flash, but the use of Java and Android as client calls is a trigger.
Adobe's red5 Source Code contains an rtmpclient class, which is not complex in use, but cannot be called successfully. Observe the log and find that the connection is closed when the stream is created after the connection is successful. What I can think of is that the current version of the red5 server used by the company may be incompatible with t
A similar article above found the time: Problems in rtmp handshake
In FFMPEG, rtmp is implemented. In handshake, C1 is, the time field is filled with 0, and the zero field is filled with client_ver. The generated 1528 is treated as follows: Enter the pseudo-random number first, then, encrypt a key in a certain location. Because we do not pay attention to the pseudo-random number generation algorithm and En

Some time ago, we set up a streaming media server that supports HLS on Ubuntu. The final goal was to build such a streaming media server on the arm Development Board. Now the job is only a small part. we are porting and recording it so that we can continue to do it later.
