• ffmpeg hwmap SW decoded frame to OpenCL and hwmap back to h264 for SW encode

  3 novembre 2019, par Oleksandr Kyrpa

  I trying speed up process and avoid copy frames between GPU and CPU. But got error : "Segmentation fault : 11", so may be I’m doing something wrong ?

  My full ffmpeg command and log here :

  ./ffmpeg -i ../720.mp4 -init_hw_device opencl=ocl:0.1 -filter_hw_device ocl  -filter_complex "hwmap,avgblur_opencl=30,hwmap"  -c:v h264 -an -t 10 -y ../out_blur.mp4 -loglevel debug

  Output :

  ./ffmpeg -i ../720.mp4 -init_hw_device opencl=ocl:0.1 -filter_hw_device ocl  -filter_complex "hwmap,avgblur_opencl=30,hwmap"  -c:v h264 -an -t 10 -y ../out_blur.mp4 -loglevel debug
