  • How to improve random access of a video frame with Python ?

    11 octobre 2024, par Paul Jurczak

    I'm using pims library (https://github.com/soft-matter/pims) to access frames from .MOV file with over 25K frames, 3840 × 2160, H.264 (High Profile), 60fps.

    


    import pims
from time import perf_counter

video = pims.Video('video/v1.MOV')
t0 = perf_counter()
img = video[1000]
t1 = perf_counter()
print(f'{(t1-t0):.3f}s  {img.shape}')


    


    Here are the timings on a fairly fast PC, after file open :

    


      

    • frame #100 : 2.97s

      • 


    • frame #1,000 : 28.39s

      • 


    • frame #10,000 : 280.19s

      • 


    


    AFAIK, this library uses ffmpeg, which can access frame #10,000 with ffmpeg -ss 00:02:46.66 -i v1.MOV -frames:v 1 f10k.png practically instantaneously. Is there a way to improve frame access with pims or some other method ?

    rtsp : Include an User-Agent header field in all requests

    Some rtsp servers like the IP Cam IcyBox IB-CAM2002 need it.
    

    Based on a patch by Carl Eugen Hoyos.

  • Hot to access video frames from external process ?

    14 août 2019, par gaamaa

    Windows 32 bit application memory limit is around 2gb approximately.
    I need to play 4 to 8 HD video files or live camera graphs. Which is not possible by a single 32 bit application.
    So I would like to play each graph in separate 32 bit application and access those video frames from my main application. In this case I could manage my need.

    Could some experts give me some clue to do this if c++ ?

    Is there any ready solution to achieve this ?
