AP WifiManager connection with conventional access points, found below the 4.1 version of the system can be connected to get on, such as Samsung i9300, HTC G7, Meizu two systems do not have to upgrade to 4.2 < / span>, and some cottage can also be made, but the same APK, put Samsung GS4, Meizu 4.2 system upgrade to 2, life and death is not connected WIFI,
PS: After seemingly open the drive, the system is connected directly to the default AP to go, do not know if there are wood predecessors encountered such a problem, or give a WIFI connection of Demo Samsung G4 line ah, Guixie it.

About Android ffmpeg problem? ? Ask you seniors! ! ! ! ! ! ! ! ! ! !

Tip avcodec_find_decoder found, but this function in the header file is there, I was not compiled into a static library when a mistake?
Many of the functions FFMPEG prompted to find
Downloaded churnlabs this project can be compiled, read engineering function in my header file is there, can be found ah

My configuration is the same path with churnlabs also include the file into your head
Reply:
Why is it I can find but can not find it
Reply:
The strange thing is I put my project JNI delete all folders, then copy churnlabs the JNI folder to the project to modify the look native.c file, NDK compile time or error, the function can not find all the FFMPEG , there is not a project where you want to set, churnlabs can be compiled using the NDK

Static files should be the right

I was wrong, the churnlabs copied all the JNI directory, refresh the project in compilation is

1. Ensure that you can open http streaming media address on a computer browser
2 There http streaming and rtsp, setDataSource url can be directly transmitted, but time-consuming preparation stage of streaming media, you can not call the start function directly after prepare, need to meidplayer registered OnPreparedListener functions. In onPrepared function to call start function.
You also have the class to write the first comment there, but did not.
