  • Cannot join mp3 file and avi file with ffmpeg

    13 novembre 2014, par RULE101

    I am using this code to join an mp3 file and video file with ffmpeg

    ffmpeg -i /file1.mp3 -ab 128k -i /file2.avi  -vcodec copy -f avi /file3.avi

    But this code gives that error

    Option ab (audio bitrate (please use -b:a)) cannot be applied to input file /file1.mp3 -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to.
    
Error parsing options for input file /file1.mp3.
    
Error opening input files: Invalid argument

    How can i do this job ?

  • How to keep the orientation number(exif) after converting from a video file to a image file by a ffmpeg command

    24 novembre 2023, par user27240

    The command below is working perfectly fine for my environment except it deletes the orientation number (EXIF) of the image file after being converted from a video file.

    


    System info :

    


      

    • FFmpeg 2.2.2

      • 


    • CentOS 6 (x86_64)

      • 


    


    I'd like to know how to keep the orientation number(exif) of the image with the command line below(it also have to keep the original purpose of its functionality which is to convert a video to a image from one directory to another.). I'd appreciate if anyone could help me out.

    


    for i in /path/to/inputs/*.mp4; do ffmpeg -i "$i" -frames:v 1 "/path/to/outputs/$(basename "$i" .mp4).jpg"; done


    


  • Connect ffmpeg and pyaudio by rtmp

    3 février 2023, par Odino Cano

    Is it possible in cross platform to create an rtmp connection with ffmpeg and pyaudio ?

    


    This the code :
Camera

    


    import sys, pyaudio, subprocess, cv2
rtmp_url = "rtmp://MYURL"
cap = cv2.VideoCapture(0)

fps = int(cap.get(cv2.CAP_PROP_FPS))
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))


    


    Command ffmpeg

    


    command = ['']



    


    Init the microphone

    


    CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1 if sys.platform == 'darwin' else 2
RATE = 44100
RECORD_SECONDS = 20
PyA = pyaudio.PyAudio()
stream = PyA.open(format=FORMAT, channels=CHANNELS, rate=RATE, input=True)
subProcess = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)


    


    Write the bytes

    


    while stream.is_active():
    ret, frame = cap.read()
    if not ret:
        print("frame read failed")
        break
    subProcess.stdin.write(frame.tobytes())

    subProcess.stdin.write(stream.read(CHUNK))
subProcess.stdin.close()


    


    All in multiplatform.
