  • Gstreamer errors when streaming on windows

    19 juillet 2014, par user2656632

    I tried to streaming video by gstreamer using this :

    Sender :

    gst-launch ksvideosrc ! ffmpegcolorspace ! ffenc_mpeg2video gop-size=1 ! mpegtsmux ! rtpmp2tpay ! udpsink host=127.0.0.1 port=5000

    Receiver :

    gst-launch udpsrc port=5000 caps="application/x-rtp, media=video, clockrate=90000, encoding-name=MP2TS" ! rtpmp2tdepay ! ffdemux_mpegts ! ffdec_mpeg2video ! ffmpegcolorspace ! directdrawsink

    It works, but wrong. I got very low fps and I got this output :

    How I can fix these issues ?

  • ffmpeg video stream to app c# [on hold]

    3 septembre 2014, par Alexey Medvedev

    I am trying to make a video mixer for online broadcasts. To do this, I use ffmpeg and C #. I had a problem with the transfer of the video stream from ffmpeg to my program. I would like to receive a stream of ffmpeg using network protocols (e.g. TCP, UDP or others) or capturing if from ffplay window, but I don`t how I can do it. Can you give me some ideas ?

    For example, I have command for ffmpeg : "ffmpeg -i video1.mp4 -f mpegts udp:127.0.0.1:5000" or same command with other output formats or network protocols. How i can read video stream from the port and convert it to Bitmap ?
    I need to send video stream from my program from computer A to my program to computer B. I write program on C#. I dont know how I can compress video which I must send between my computers and I decided to use Ffmpeg. Now, I can streaming video from my program in computer A to ffmpeg and compress it with parameters which I need.
    On second computer I can read this steam using ffmpeg or ffplay, but I don`t know how I can get this stream into my program.
    1) How can I get this stream in my program ? Which libraries can you recommend me ?
    2) Do you know any libraries which can compress video, instead of using ffmpeg ?

  • 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 :
