javacv已经出了1.0版本,整个库改动很大,Android-ffmpeg-CameraRecord能不能更新到javacv-1.0?
现在最新的javacv已经移动到了github,但是我从github编译出的so库并没有ffmpegInvoke和neno的so库,你的库代码应该是googlecode的;
github的库编译之后出现录制过程中会出现闪退的情况,请问你的库是怎么编译出来的

分析原因是由于拍照方法里面的 Buffer 未及时释放导致内存占用增加,最终在拍照线程中溢出,这里给出一点儿改进建议,希望作者更新代码,感谢~
改进方法:在照线程中增加释放Buffer的语句:mBuffer.clear();
原代码:
bmp.copyPixelsFromBuffer(mBuffer);
ImageUtil.saveBitmap(bmp);
改进代码:
bmp.copyPixelsFromBuffer(mBuffer);
ImageUtil.saveBitmap(bmp);
mBuffer.clear();
CameraDemoActivity中的FilterNames只有四种,FilterTypes有五种,所以在:
for(int i = 0; i != FilterTypes.length; ++i) {
MyButtons button = new MyButtons(this);
button.filterType = FilterTypes[i];
button.setText(FilterNames[i]);
button.setOnClickListener(mFilterSwitchListener);
layout.addView(button);
}
中出现了越界
根据demo运行出来的视频是颠倒的?如何解决?
比如我每隔70到100ms生成一帧,时间是变化的,我怎么设置能正常录制呢,现在demo录制出来播放的时候相当于快进。
