FATAL occured while opening videos in scripts/extract_optical_flow.sh about temporal-segment-networks HOT 14 CLOSED

If the video path is surely correct, one remaining issue might be the OpenCV is compiled without VideoIO support. Please cd into the build folder of OpenCV 3rd-party/opencv-2.4.12/build/ and run the command cmake ..

In the output lines, please try to find the section about VideoIO. On my workstation, it shows something like

--   Video I/O:
--     DC1394 1.x:                  NO
--     DC1394 2.x:                  YES (ver 2.2.1)
--     FFMPEG:                      YES
--       codec:                     YES (ver 54.35.0)

--       util:                      YES (ver 52.3.0)
--       swscale:                   YES (ver 2.1.1)

Thank you for the quick response @yjxiong!

Just like you said, my openCV didn't support the Video I/O.
The problem is solved after I ran apt-get install libopencv-dev and thecmake .. command to re-install openCV

from temporal-segment-networks.

@yjxiong ，The openCV came from the TSN installation package, it should be okay.
excute scripts/extract_optical_flow.sh ,the log as follows:

Any suggestion to solve this problem?

I meet the same problem as you,could you solve this problem and share with me how to solve it？

from temporal-segment-networks.

@Ivy-blooming Have you solved the problem?

from temporal-segment-networks.

@yjxiong @GBJim I am seeing the same issue. So I did install apt-get install libopencv-dev and did cmake .. But still see the same.
make -j32 fixed it

from temporal-segment-networks.

I am trying to run -
scripts/extract_optical_flow.sh /home/nirahurk/temporal-segment-networks/src_folder/ /home/nirahurk/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:
4 v_SkateBoarding_g25_c01 done
3 v_SkateBoarding_g25_c03 done and so on..
But my out_folder --> out_folder/v_SkateBoarding_g25_c01# is empty.

My parameters look right:
('flow_type: ', 'tvl1') ('reading videos from folder: ', '/home/nirahurk/temporal-segment-networks/src_folder') ('selected extension of videos:', 'avi') ('total number of videos found: ', 5)

@124399839 @Ivy-blooming Have you solved that problems ? if you have done it ,how did you do it?

i still got this problem, but my video io seems ok?

我遇到了同样的问题，最后发现是磁盘空间满了。

I use the docker too, but it does not work.
