  • FFMPEG - Converting any kind of file to Mp4 compatible with IOS and Flash

    5 février 2013, par arashaga

    I am struggling with FFmpeg whithing Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
    I have used the following commands so far, please note that the variables starting with " !" are placeholders and will be replaces with the proper items :

    FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile
    

    
FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfile

    The above command produce an error as :

    error executing command for rendering preset HTML5 MP4, command #1 :

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
    
Alternatively use the non experimental encoder 'libfaac'.

    Another command that I used is :

    FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

    Can any help me with online video converter ?

  • Gsteamer rtp video mixer, found a working pipeline, however need improvement

    8 février 2015, par alkber

    I’m attempting to mix multiple rtp h264 payload video streams into a single video stream of 15FPS.

    A working pipeline that mixes two video streams over a videotestsource pattern of 15FPS

    VIDEO_CAPS="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264"
    

    
gst-launch -vvvve videomixer2 name=mix ! ffmpegcolorspace ! xvimagesink  
    

    
udpsrc caps=$VIDEO_CAPS port=3030 ! .recv_rtp_sink_0 gstrtpbin ! rtph264depay ! ffdec_h264  ! videoscale ! video/x-raw-yuv , width=176, height=144 ! videobox top=0 left=0 ! video/x-raw-yuv,format=\(fourcc\)AYUV ! ffmpegcolorspace !  mix.  
    

    
udpsrc caps=$VIDEO_CAPS port=6666 ! .recv_rtp_sink_0 gstrtpbin ! rtph264depay ! ffdec_h264  ! videoscale ! video/x-raw-yuv , width=176, height=144 ! videobox top=0 left=-178 ! video/x-raw-yuv,format=\(fourcc\)AYUV ! ffmpegcolorspace !  mix. 
    

    
videotestsrc ! video/x-raw-yuv, framerate=15/1, width=640, height=360 ! mix.

    Above pipeline has a strange issue, When attempting to mix, the first video source goes blank, (i’m certain that there is still streaming going on for the first video source, however it doesn’t turn up. Rather second video stream is shown. The verbose is given below.

    Verbose for the above pipeline

    I highly suspect it has something to with videobox.
