  • Issue #3 when compiling Xuggler for Raspberry pi with liboil

    19 juillet 2014, par Ashish Sharma

    I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

    I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

    After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

    ant run-tests

    After sometime I am facing the following error and the ant build fails :

    scroll at the end of log to see the issue

        Incarcerated package configured: ../../../../../captive/liboil
    
Incarcerating package ../../../../../captive/liboil to fake DESTDIR=/home/pi/Downloads/xuggle-xuggler/build/native/armv6l-unknown-linux-gnueabihf/captive/stage

    I tried correcting the mentioned shell script but to no avail,

    Please help, following is the shell script code :

    if [ "" = "1" ]; then

  # needed for mingw32 cross-compile to work

  • 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 :

  • ffmpeg : deshake and crop 2k to 1080p ?

    12 septembre 2017, par est

    There are great tutorials of how to use ffmpeg to

    1. deshake a video, either via 1pass of deshake filter or using vid.stab for a 2pass filter
    2. how to downsampling to 2k video to 1080p

    I have a video taken by an action camera, it’s wide angle, so lots of margins could be cropped out, I want to

    1. deshake it and fix the camera to a center stage
    2. cropping a 2304 × 1296 video to 1080p, without downsampling.
    3. Convert original H.264 to HVEC to better file size

    How can I achieve this in one step without lossy intermediate video files ?
