求救 怎样使用ffmpeg函数接收rtsp 网络数据

Answer 1

下面是jni里的函数

C/C++ code?

void Java_com_Helloworld_HelloworldActivity_openFile(JNIEnv * env, jobject this,jstring filename)
{
int ret;
int err;
int i;
AVCodec *pCodec;
uint8_t *buffer;
int numBytes;

av_register_all();
LOGE("Registered formats");
const char* filestr;
filestr = (*env)->GetStringUTFChars(env,filename,0);
if( filestr == NULL ){
return;
}
LOGE("file= [%s] ",filestr);
err = av_open_input_file(&pFormatCtx, filestr, NULL, 0, NULL);
(*env)->ReleaseStringUTFChars(env,filename,filestr);
LOGE("file= [%s] ",filestr);

LOGE("Called open file");
if(err!=0) {
LOGE("Couldn't open file");
return;
}
LOGE("Opened file");
