i think it needs load the native lib for convertVideoFrame fuction

[lalongooo]

Do you have the NDK installed?
}

[devesh1991]

If library is already compiled then no need to USE NDK.

I am getting same error even in your sample. please help us to resolve the problem

[TheSikh]

You have to compile the .so file again if you move or rename the java class in which native method is declared you need to change the corresponding native method name in c file. In our case we have video.c file in jni folder. We need to update the method name according to the package name of java class which will be using this method and also adding "Java_" as prefix to method name. Hope this Help.

Thanks.

Thanks for your comments @deep7964. @trantung998, please give it a try.. 😁

[trantung998]

[devesh1991]

I am still getting same crash on 4.2.2

[lalongooo]

Have you tried the @deep7964 solution?

[devesh1991]

I tried to compile but getting error of some imports, include file.
I am using Ndk Revision 10d.
I request you to compile at your side

I also have this problem:

In file included from /Users/fabiocarballo/VideoCompressor/app/src/main/jni/./libjpeg/armv6_idct.S:63:0:

      ^
make: *** [/Users/fabiocarballo/VideoCompressor/app/src/main/obj/local/armeabi/objs/tmessages.7/./libjpeg/armv6_idct.o] Error 1

Im using the latest ndk (10) to compile. Do you have any idea on how to solve this? @lalongooo

[lalongooo]

@deep7964 @fabiocarballo I'll reopen this issue and take a look later 😄

[dineshswaas]

@trantung998 , use below width and height for " Green bar issuee....." . its works for me...
int resultWidth = 960;
int resultHeight = 640;
thanks ...... :) happy coding....

[TxShon]

how do you compile the .so file again @deep7964,when i compile it, i got 'opus.h' file not found error.
