It is probably the smallest(~60KB) rtmp client for android. It calls librtmp functions over JNI interface. With all cpu architectures(arm, arm7, arm8, x86, x86-64, mips) its size is getting about 300KB
It compiles librtmp library without ssl.
In version 0.2, it supports FL 63A5 V muxing and sending stream via RTMP. FLV muxing is based on this repo https://github.com/rainfly123/flvmuxer
#####To read streams, you can call below functions of RtmpClient from Java#####
For live streams add " live=1" at the end of the url when calling the open function
- public native int open(String url, boolean isPublishMode);
- public native int read(byte[] data, int offset, int size);
- public native int write(byte[] data);
- public native int seek(int seekTime);
- public native int pause(int pause);
- public native int close();
- public native int isConnected();: Call this function to query the connection status. Returns 1 if connected, returns 0 if not connected
Don't forget calling the close function after you are done. If you don't, there will be memory leakage
#####To publish streams, you can call below functions of RtmpMuxer from Java#####
- public native int open(String url); : First, call this function with the url you plan to publish
- public native int writeVideo(byte[] data, int offset, int length, int timestamp);: Write h264 nal units with this function
- public native int writeAudio(byte[] data, int offset, int length, int timestamp);: Write aac frames with this function
- public native int close();: Call this function to close the publishing.
- public native int isConnected();: Call this function to query the connection status. Returns 1 if connected, returns 0 if not connected
To save flv file locally as well, you can use below functions
- public native void file_open(String filename); : call this function with full file path
- public native void write_flv_header(boolean is_have_audio, boolean is_have_video);: After opening file call this function
- public native void file_close();: Call this function to close the file.
if any local file is opened, library will write the audio and video frames to local file as well.
- Add dependency to your build gradle
dependencies {
...
compile 'net.butterflytv.utils:rtmp-client:0.2.1'
...
}- That's all. You can use RtmpClient class
This project is developed for Butterfly TV
