How to reset NvVideoEncoder VideoEncoder object?

Hi,

I’m use argus sample frontend VideoEncoder.h to encode video from camera image, it works fine.
And now I want to save different videos per 2000 frame. But after I called encoder.encodeFromFd(-1) to close previous video, encoder.encodeFromFd(image_dma_id) not work. My process like this:

encoder.encodeFromFd(A);
encoder.encodeFromFd(B);
encoder.encodeFromFd(C);
encoder.encodeFromFd(-1);
encoder.reset();// how to coding it?
encoder.encodeFromFd(D);
encoder.encodeFromFd(E);
encoder.encodeFromFd(F);

Or,may I know what is the length of video header from first frame? Then I can write header to every video file. Then I can change to below:
encoder.encodeFromFd(A);
encoder.encodeFromFd(B);
encoder.encodeFromFd(C);
Write:header,A,B,C

encoder.encodeFromFd(D);
encoder.encodeFromFd(E);
encoder.encodeFromFd(F);
Write:header,D,E,F

Hi,
PLease refer to 01_video_encode. It demonstrates complete function of video encoding. Also it is verified in stress test. You can set below option:

-s <loop-count>       Stress test [Default = 1]

@DaneLLL , the demo code actually destruct and re-create that NvVideoEncoder in each loop, so it is not what we are looking for,
For NVENC, we have “NvEncReconfigureEncoder” but that is not actually available on jetson platform. Is there anything similar that we can use to avoid the cost of destruct and re-create that NvVideoEncoder but still reset the NvVideoEncoder?

thanks

Hi wsmlby,

Please help to open a new topic if still an issue. Thanks
