so库里 资源都有释放么 不然会内存增加崩溃的

int argc = (*env)->GetArrayLength(env, commands);
char **argv = (char **) malloc(argc * sizeof(char *));
int i;
int result;
for (i = 0; i < argc; i++) {
jstring jstr = (jstring) (*env)->GetObjectArrayElement(env, commands, i);
char *temp = (char *) (*env)->GetStringUTFChars(env, jstr, 0);
argv[i] = malloc(1024);
strcpy(argv[i], temp);
(*env)->ReleaseStringUTFChars(env, jstr, temp);
}
//execute ffmpeg cmd
result = run(argc, argv);
//release memory
for (i = 0; i < argc; i++) {
free(argv[i]);
}
free(argv);
