    une erreur grossière de caractères en trop

  • multiple GPU encoding use FFMPEG under multiple threads environment

    8 septembre 2022, par shenuo

    Here is the application situation.
I want use 4 NV GPUs to carry out some calculation work (CUDA based), and encoding work (FFMPEG &NVEC), it works fine when they are in serial. But when I want them to be parallel. like this

    


    void encodingwork(){
            #pragma omp parallel for num_threads(4)
                for (int i = 0; i < 4; i++) {
                    cudaSetDevice(i);
                    encodingwork();
                }
        }

        int main(){
            thread thd;
            for (int k = 0; k < N; k++) {
#pragma omp parallel for num_threads(4)
                for (int i = 0; i < 4; i++) {
                    cudaSetDevice(i);
                    cudawork();
                }
                if (k != 0)
                    thd.join();
                thd = thread(encodingwork);
            }
            thd.join();
        }


    


    an error will be thrown out from ffmpeg. just like

    


    [AVHWDeviceContext @ 000002334959ac80] cu->cuMemFree((CUdeviceptr)data) failed -> CUDA_ERROR_ILLEGAL_ADDRESS: an illegal memory access was encountered

[hevc_nvenc @ 00000230c956b200] EncodePicture failed!: generic error (20):
Error sending a frame for encoding: -1313558101 (Unknown error occurred)


    


    can anybody tell me what's wrong with this ?

    


  • Revision 7eca086707 : Add segmentation map array for current and last frame segmentation. The origina

    17 juillet 2014, par hkuang

    Changed Paths :
     Modify /vp9/common/vp9_alloccommon.c


     Modify /vp9/common/vp9_alloccommon.h


     Modify /vp9/common/vp9_entropymode.c

     Modify /vp9/decoder/vp9_decoder.c



    Add segmentation map array for current and last frame segmentation.

    The original implementation only allocates one segmentation map and this
    works fine for serial decode. But for frame parallel decode, each thread
    need to have its own segmentation map and the last frame segmentation map
    should be provided from last frame decoding thread.

    After finishing decoding a frame, thread need to serve the old segmentation
    map that associate with the previous decoded frame. The thread also need to
    use another segmentation map for decoding the current frame.
