• 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

• ffmpeg giving Error while decoding stream #0:1 : Invalid data found when processing input

  11 octobre 2023, par user1432181

  I am trying to merge two video files into one using ffmpeg on Windows. The process has been proven to work over and over (with over 100 files merged together at some points) - but I have come across an input file that is causing the process to fail with the errors :

  


  _[aac @ 00000142532f74c0] channel element 1.0 is not allocated
Error while decoding stream #0:1: Invalid data found when processing input
[aac @ 00000142532f74c0] channel element 1.0 is not allocated
Error while decoding stream #0:1: Invalid data found when processing input
[aac @ 00000142532f74c0] channel element 1.0 is not allocated
.
.
.


  


  There seems to be 3 command line steps to get here, using a concats-inputs.dat file containing :

  


  file E:/..../snippet A.mp4
file E:/..../snippet B.mp4


  


  (Copies of these files can be found at https://filebin.net/77wbowvh7vbklkey/snippet_A.mp4 and https://filebin.net/77wbowvh7vbklkey/snippet_B.mp4)

  


  Step 1 :

  


  > ffmpeg-6.0-full_build/bin/ffmpeg -y -progress ".Default.mp4.progressinfo.dat" -vsync 0 -f concat -safe 0 -i "E:/...../concat-inputs.dat" -c:v copy -c:a copy -crf 0 -b:v 10M "E:/...../video.Default.mp4"


  


  with the output....

  If I was to do this to merge snippet B with snippet B then it would work - it's something about snippet A that is causing the problem.

  


  Is there any way to get around this... what is it about snippet A that is causing a problem... and is there a way to "normalize" it so that it can be merged as part of the "set".

  


  Note, I just upgraded to ffmpeg6 after a previous version was giving the same problems - so I will also work on the deprecated messages when I can.

  


• ffmpeg giving Error while decoding stream #0:1 : Invalid data found when processing input

  12 octobre 2023, par Aby

  I am trying to merge two video files into one using ffmpeg on Windows. The process has been proven to work over and over (with over 100 files merged together at some points) - but I have come across an input file that is causing the process to fail with the errors :

  


  _[aac @ 00000142532f74c0] channel element 1.0 is not allocated
Error while decoding stream #0:1: Invalid data found when processing input
[aac @ 00000142532f74c0] channel element 1.0 is not allocated
Error while decoding stream #0:1: Invalid data found when processing input
[aac @ 00000142532f74c0] channel element 1.0 is not allocated
.
.
.


  


  There seems to be 3 command line steps to get here, using a concats-inputs.dat file containing :

  


  file E:/..../snippet A.mp4
file E:/..../snippet B.mp4


  


  (Copies of these files can be found at https://filebin.net/77wbowvh7vbklkey/snippet_A.mp4 and https://filebin.net/77wbowvh7vbklkey/snippet_B.mp4)

  


  Step 1 :

  


  > ffmpeg-6.0-full_build/bin/ffmpeg -y -progress ".Default.mp4.progressinfo.dat" -vsync 0 -f concat -safe 0 -i "E:/...../concat-inputs.dat" -c:v copy -c:a copy -crf 0 -b:v 10M "E:/...../video.Default.mp4"


  


  with the output....

  If I was to do this to merge snippet B with snippet B then it would work - it's something about snippet A that is causing the problem.

  


  Is there any way to get around this... what is it about snippet A that is causing a problem... and is there a way to "normalize" it so that it can be merged as part of the "set".

  


  Note, I just upgraded to ffmpeg6 after a previous version was giving the same problems - so I will also work on the deprecated messages when I can.
