Unable to use extract flow
I am trying to run -
scripts/extract_optical_flow.sh /temporal-segment-networks/src_folder/ /temporal-segment-networks/out_folder/ 1
I have taken just 5 sample videos from UCF101 in my src_folder:
v_SkateBoarding_g25_c01 v_SkateBoarding_g25_c02 v_SkateBoarding_g25_c03 v_SkateBoarding_g25_c04 v_SkateBoarding_g25_c05
I get the output:
0 v_SkateBoarding_g25_c05 done
4 v_SkateBoarding_g25_c01 done
1 v_SkateBoarding_g25_c02 done
3 v_SkateBoarding_g25_c03 done
2 v_SkateBoarding_g25_c04 done
But my out_folder --> out_folder/v_SkateBoarding_g25_c01# is empty.
My parameters look right:
('flow_type: ', 'tvl1') ('reading videos from folder: ', '/temporal-segment-networks/src_folder') ('selected extension of videos:', 'avi') ('total number of videos found: ', 5)
Not able to figure out what's going wrong. I reinstalled dense-flow as I thought some issue with build/extract_gpu but didn't help. Any ideas what could be the problem?
Met same problem. How to fix. On windows,it can be fixed by making copy opencv ffmpeg dll to current directory. but on linux, this kind of so file can not be found.

@raozhongyu and @a-whitej Did you try with the docker container that they have provided? You should not see any issues if you run the scripts from inside the container.
the problem is that opecv is not be installed correctly. during compiling opencv on problem i manually run compile such as /usr/bin/c++ -isystem /usr/local/include/opencv -isystem /usr/local/include -I/home/my/dev/opencv-3.1.0/modules/cudaarithm/include -I/home/my/dev/opencv-3.1.0/modules/cudaoptflow/include -I/home/my/dev/opencv-3.1.0/modules/cudacodec/include -I/usr/lib/x86_64-linux-gnu/libzip/include -I/home/my/dev/dense_flow/include -I/home/my/dev/dense_flow/include/easylogging++/src -I/home/my/dev/dense_flow/include/CLUE/include -std=c++11 -fPIC -o CMakeFiles/denseflow.dir/src/dense_flow_gpu.cpp.o -c /home/my/dev/dense_flow/src/dense_flow_gpu.cpp /usr/bin/c++ -isystem /usr/local/include/opencv -isystem /usr/local/include -I/home/my/dev/opencv-3.1.0/modules/cudaarithm/include -I/home/my/dev/opencv-3.1.0/modules/cudaoptflow/include -I/home/my/dev/opencv-3.1.0/modules/cudacodec/include -I/usr/lib/x86_64-linux-gnu/libzip/include -I/home/my/dev/dense_flow/include -I/home/my/dev/dense_flow/include/easylogging++/src -I/home/my/dev/dense_flow/include/CLUE/include -std=c++11 -fPIC -o CMakeFiles/denseflow.dir/src/dense_warp_flow_gpu.cpp.o -c /home/my/dev/dense_flow/src/dense_warp_flow_gpu.cpp

then problem sovled.
@niveditarahurkar I used Docker, but the following error occurred while running bash build_all.sh inside: can you help me fix it?

我也是用docker来运行的，最后生成的同样是空文件夹，跟你的问题一样，你现在解决这个问题了嘛？
