  • extract timestamp from a frame. OpenCV gives wrong results

    24 juillet 2012, par ar ar ar

    I have an avi video with H264-MPEG-4 AVC codec.

    I have a c++ project in which I use OpenCv. So I take every frame with OpenCv and want to know about the timestamp of the frame in reference to the video length.

    OpenCv p0orperties give me wrong results as for the timestamp and the frame count.

    So I thought of using ffmpeg to extract the correct timestamp of the frame, but my kwoleedge of ffmpeg is minimal.

    Can somebody advice what I need to do ?? Maybe which libraries of ffmpeg to use ?

    Or to give me an answer why is this happening to openCv ?

  • Disable i8x8 in lossless

    Disable i8x8 in lossless

    x264’s implementation was slightly incorrect due to a vague spec, so some
    
decoders decoded video incorrectly.
    

    Minimal impact on compression.

  • File created in subprocess.run not found by os.listdir()

    13 novembre 2019, par Abitbol

    I am using subprocess to launch an instance of ffmpeg extracting frames in a folder. Then I do os.listdir on that same folder and it returns an empty list ; off course I would except to see the files created by ffmpeg listed.

    Here is a minimal example

    import os
    
import subprocess
    

    
folder = 'generated'
    
subprocess.run(['ffmpeg', '-i', 'input.mp4', '-vf', 'fps=4', f'{folder}/%05d.png'])
    
print(os.listdir(folder))  # []

    I can testify that the files are created while the script is running.

    In the full example I am using ffmpeg complex filter to generate two output, I don’t think that is the source of the problem.
