  • How to record UDP stream with FFMPEG in chunks ?

    30 janvier 2018, par user1394281

    I’m looking for a way to record a video UDP stream using ffmpeg but in 10mn chunks.
    I currently use the following to get 10mn of video (with h264 transcoding).

    "ffmpeg -i udp ://239.0.77.15:5000 -map 0:0 -map 0:1 -s 640x360 -vcodec libx264 -g 100 -vb 500000 -r 25 -strict experimental -vf yadif -acodec aac -ab 96000 -ac 2 -t 600 -y /media/test.m4 "

    My problem is that using command line ffmpeg needs time to resync with the udp stream loosing 2 seconds of video each time. Is it normal ?

    Any idea if there is a way to do it in command line or should I tried to use the ffmpeg API ?

    Thanks in advance

  • ffmpeg image and flask app in two different containers in Docker compose. How do I use ffmpeg in flask app ?

    14 novembre 2017, par Conor Quinn

    Here is my docker compose yml file :

    ffmpeg:
    
    image: jrottenberg/ffmpeg:ubuntu
    
    tty: true
    
flask_app:
    
  build: ./flask_app
    
  #image: conorquinn01/composeapp
    
  command: python ./flask_app/app.py

   - "5000:5000"
    
  volumes:
    
   - .:/muse_compose2
    
  links:

    Not sure how to do this. Thanks.

  • Gstreamer channel reordering failed

    31 octobre 2017, par user972851

    I installed the library essentia which causes my previously working pipeline to crash :

    ** (gst-launch-1.0:22515): CRITICAL **: gst_audio_reorder_channels: assertion 'size % ((info->width * channels) / 8) == 0' failed
    
ERROR: from element /GstPipeline:pipeline0/GstRtpL16Depay:rtpl16depay0: Channel reordering failed.
    
Additional debug info:
    
gstrtpL16depay.c(276): gst_rtp_L16_depay_process (): /GstPipeline:pipeline0/GstRtpL16Depay:rtpl16depay0

    The pipeline looks like this :

    udpsrc port=5000 ! application/x-rtp,media=(string)audio,channels=1, clock-rate=(int)44100,encoding-name=(string)L16,payload=10 ! rtpL16depay ! audioconvert ! tee name=t ! queue ! autoaudiosink sync=false t. ! queue ! appsink name=codesink

    I am using gstreamer 1.0 on Ubuntu 16.04 and (re-)installed the libraries mentioned in the essentia doc :

    build-essential libyaml-dev libfftw3-dev libavcodec-dev libavformat-dev libavutil-dev libavresample-dev python-dev libsamplerate0-dev libtag1-dev
    
python-numpy-dev python-numpy python-yaml
    
ffmpeg

    The essentia install script finished ’successfully’ even though I cannot find MonoLoader or any other Audioloader.... (so still something wrong with essentia as well, but thats not the main problem !)

    Cleaned out parts of the gstreamer debug log look like this :
