process on video recording

[msalamah82]

Dear friends
I hope that every one is ok.
Did any one make a processing of video frames when record a video? I see the video_recording.py I did get where is the function which calls when the frame is read to save on the file. What I like to do is to add the date on every frame.

Real-time video processing is not feasible in Python due to its interpreted nature and execution slowness. You need to write C++ extension for this.

Dear friend miohtama. 1st of all thanks for your replay.
I start study the pyS60 and I get in the same example of the video record I found this function

def finder_cb(im):
    global control_light
    if control_light==1:
        im.point((20, 20), outline = (255, 0, 0), width = 25) 
    else:
        im.point((20, 20), outline = (0, 255, 0), width = 25) 
    canvas.blit(im)

The system will pass every frame comes from the camera.
And I can make the processing in this function.
And about the speed of processing. Python is powerful in list and matrix. And this is all what we need.

And I am vary interesting to know your opinions about pyS60 process time.
