  • python ffmpeg not decoding text from webcam video frame

    13 juin 2024, par sar5050

    I am trying to construct python script with ffmpeg command to capture a webcam, decode the text from the camera frame and stream the same through an RTSP stream. I am able to receive the streaming through the player, but text decoding is not happening with the following example code : Help is needed to understand the problem, whether it is a piping problem or any other mistake in the code.

    


    ffmpeg_cmd = (
    "ffmpeg -f v4l2 -framerate 30 -video_size 1280x720 -i /dev/video0 -f alsa -i hw:0 -c:v libx264 -preset ultrafast -tune zerolatency -pix_fmt yuv420p -c:a aac -b:a 128k -f rtsp rtsp://localhost:8554/stream"
)

pytesseract_cmd = (
    "pytesseract --tessdata-dir /usr/share/tesseract-ocr/4.00/tessdata/ -l eng --oem 3 --psm 6 stdin stdout"
)

ffmpeg_process = subprocess.Popen(ffmpeg_cmd.split(), stdout=subprocess.PIPE)
pytesseract_process = subprocess.Popen(pytesseract_cmd.split(), stdin=ffmpeg_process.stdout, stdout=subprocess.PIPE)

while True:
    frame = np.frombuffer(ffmpeg_process.stdout.read(1280*720*3), dtype=np.uint8).reshape((720, 1280, 3))
    text = pytesseract_process.stdout.readline().strip()
    print(text)

  • How to extract duration time of online videos listed in a text file

    22 août 2022, par Ginofalaci

    I need to check the duration of thousand of videos online. I m trying to get this from a text file containing the urls of the videos.

    


    I have those two commands that are working great with one url, but i don't find out how to get it work with a list within a file text.

    


    fmpeg -i My.url 2>&1 | grep "Duration"| cut -d ' ' -f 4 | sed s/,//


    


    or this :

    


    ffmpeg -i my.url 2>&1 | grep Duration | sed 's/Duration: \(.*\), start/\1/g'


    


    im trying :

    


    fmpeg -i listurls.txt 2>&1 | grep "Duration"| cut -d ' ' -f 4 | sed s/,//


    


    or this :

    


    ffmpeg -i listurls.txt 2>&1 | grep Duration | sed 's/Duration: \(.*\), start/\1/g'


    


    my file text is like this :

    


    myurl1.m3u8
    
myurl2.m3u8
    
myurl3.m3u8
    
myurl4.m3u8
    
myurl5.m3u8

    


    I've also tried :

    


    file 'myurl1.m3u8'
    
file 'myurl2.m3u8'
    
file 'myurl3.m3u8'
    
file 'myurl4.m3u8'
    
file 'myurl5.m3u8'

    


    but it doesn't work.

    


    Also some videos might not be online anymore, but still referenced, so it would give no result, but I would like if possible to have the result "0" than nothing, it will be much easier to use the results afterwards.

    


    (awk, sed, mediainfo, exiftool, any will be good, ) Thanks in advance.
