  • ffmpeg - Have troubling syncing up audio and video together

    15 février 2017, par zyeek

    I have a webcam and a separate mic. I want to record what is happening.

    It almost works, however the audio seems to play quickly and parts missing while playing over the video.

    This is the command I am currently using to get it partially working

    ffmpeg -thread_queue_size 1024 -f alsa -ac 1 -i plughw:1,0 -f video4linux2 -thread_queue_size 1024 -re -s 1280x720 -i /dev/video0 -r 25 -f avi -q:a 2 -acodec libmp3lame -ab 96k out.mp4

    I have tried other arguments, but unsure if it has to do with the formats I am using or incorrect parameter settings.

    Also, the next part would be how to stream it. Everytime I try going through rtp it complains about multiple streams. I tried doing html as well, but didn’t like the format. html html://localhost:50000/live_feed or rts rts://localhost:5000

    edit :

    I am running this on a rpi 3.

  • FFMPEG split video with equal frames in the splits....?

    17 janvier 2017, par Gurinderbeer Singh

    I am using FFMPEG to split a video file by using the following command :

    ffmpeg -i input.mp4 -c copy -segment_times 600,600 -f segment out%d.mp4

    This command divides video based on time.. But even if output splits are of same duration, number of frames are different in the splits..

    Is there a way of splitting a video file without recoding so that number of frames are equal in splitted files.?

    Even if it use some other tool than FFMPEG.

    For example : input.mp4 of duration 200 seconds has 5000 frames.

    Can we split this into :

    input1.mp4 having 2500 frames
    and input2.mp4 having 2500 frames.

    It doesn’t matter if duration of output splits is different..

    Please help.....!

  • ffmpeg Audiosegment error in get audio chunks in socketIo server in python

    26 janvier 2024, par a_crszkvc30Last_NameCol

    I want to send each audio chunk every minute.
this is the test code and i want to save audiofile and audio chunk file.
then, i will combine two audio files stop button was worked correctly but with set time function is not worked in python server.
there is python server code with socketio

    


    def handle_voice(sid,data): # blob 으로 들어온 데이터 
    # BytesIO를 사용하여 메모리 상에서 오디오 데이터를 로드
    audio_segment = AudioSegment.from_file(BytesIO(data), format="webm")
    directory = "dddd"
    # 오디오 파일로 저장
    #directory = str(names_sid.get(sid))
    if not os.path.exists(directory):
        os.makedirs(directory)
 
    # 오디오 파일로 저장
    file_path = os.path.join(directory, f'{sid}.wav')
    audio_segment.export(file_path, format='wav') 
    print('오디오 파일 저장 완료')`
 


    


    and there is client
