  • python - record and preview webcam at the same time, using e.g. ffmpeg

    18 décembre 2024, par Jan Oechsler

    I want to record webcam with sound using python. After tryng multiple different methods, ffmpeg with the python wrapper showed the best results.

    


    Recording works, but how can I preview the webcam at the same time, so I know where I am pointing the cam at ?

    


    I've seen this post, but I dont understand how I could implement this in python, using the wrapper.

    


    Any ideas on how to do this ? Or if there is another, easier, solution to record webcam video with sound and preview it simultaneously from within a python (Qt) application ?

    


    This is my code so far :

    


    import ffmpeg
import time

process = (
    ffmpeg
    .input('video=Integrated Camera:audio=Microphone Array (Realtek(R) Audio)', format='dshow')
    .output('out.mp4', pix_fmt='yuv420p')
    .overwrite_output()
    .run_async(pipe_stdin=True, pipe_stderr=True, quiet=True)
)

# This is just to simulate some time-
time.sleep(10)

process.stdin.write('q'.encode())
process.communicate()
process.wait()

print('done')


    


  • Converted mp4 h264 baseline format loads long time

    10 juillet 2013, par user1830062

    I have converted my video to mp4 x264 baseline format and it works fine with all pc/mobile phones , the problem is it takes long time to load the video while googling came to know that ffmpeg converts and sets the index file at the eof the video so it loads to the end to read and then plays the video, So any advices would be appreciatable to cut short the loading time.
    Note:tryied out QT index swapper2 but dint give much difference , please advice .

    this is the cmd i used to convert -

    ffmpeg -i … -c:v libx264 -profile:v baseline -level 1 …

    Thanks for your time .
