Error while using skvideo.io about scikit-video HOT 16 CLOSED

If "which ffmpeg" can't find ffmpeg, then scikit-video can't find it. This simply means that ffmpeg is not found by looking into the $PATH directories. If you aren't doing a local build of ffmpeg, then you should install ffmpeg through your package manager.

Have you tried (assuming you use ubuntu):
sudo apt-get install ffmpeg

For mac, there is likely a brew install option, though I'm only familiar with local installs for macs.

Do you have ffmpeg installed? Can you post the output to running ffmpeg in
the terminal?

While running the code

print(videodata.shape)

I am getting error AssertionError: Cannot find installation of real FFmpeg
(which comes with ffprobe).

When I am running whereisffmpeg or which ffmpeg it does not produces any output.
Is there any other method to find out if ffmpeg is installed or not?

from scikit-video.

Thank you for your help and I was able to install ffmpeg and now below code
import skvideo.io
import skvideo.datasets
import skvideo.utils

filename = skvideo.datasets.bigbuckbunny()

print("Loading only luminance channel")
vid = skvideo.io.vread(filename, outputdict={"-pix_fmt": "gray"})[:, :, :, 0]
print(vid.shape)
print("Enforcing video shape")
vid = skvideo.utils.vshape(vid)
print(vid.shape)
print("")

print("Loading only first 5 luminance channel frames")
vid = skvideo.io.vread(filename, num_frames=5, outputdict={"-pix_fmt": "gray"})[:, :, :, 0]
print(vid.shape)
print("Enforcing video shape")
vid = skvideo.utils.vshape(vid)
print(vid.shape)
print("")

is giving correct output.

So now the problem which remains is I want to use skvideo.IO.VideoCapture function and it is not described in any of the skvideo folder so when I use videocapture(filename) then error is
"cannot import name videocapture" so where can I get videocapture definition,Please suggest

from scikit-video.

Ah, at this time, I and @aizvorski are working on merging the old scikit-video codebase in with a future release. In other words, we will include the VideoCapture function, but it's not yet included at this time.

What version of skvideo do you have installed?

from scikit-video.

resolved the installation , the issue was that i was not building oit from source ,thereafter i used these commands
run chmod 777 init.sh
run sh init.sh
it worked fine

from scikit-video.

thanks for help @beyondmetis

from scikit-video.

I don't understand where init.sh comes from, and I know that scikit-video works from the pip installation so building is only necessary when you want the latest bug fixes. I'm confused, but I'm glad you were able to fix your problem.

from scikit-video.

I have installed ffmpeg and posted the output to running ffmpeg in the terminal: /usr/bin/ffmpeg,but my pycharm: Cannot find installation of real FFmpeg.

from scikit-video.

Does /usr/bin/ffprobe exist?

from scikit-video.

I have existed it .

from scikit-video.

All of [trian_*.py] have the same question,i want modify io.py.vreader() 0.0

from scikit-video.

You can try setting the ffmpeg path manually. Check out the documentation.
