• Unbound variable error when installing ffmpeg on openshift online

  31 août 2016, par sinabakh

  I followed the steps on https://forums.openshift.com/ffmpeg but when performing make install I got this error :

  And It’s the install file(which gives error) :

  #!/bin/bash -eu
  
  
  
  source $OPENSHIFT_CARTRIDGE_SDK_BASH
  
  
  
  case "$1" in
  
       -v|--version)
  
       version="$2"
  
  esac
  
  
  
  echo "$version" > ${OPENSHIFT_PYTHON_DIR}env/OPENSHIFT_PYTHON_VERSION
  
  
  
  mkdir -p ${OPENSHIFT_PYTHON_DIR}template
  
  
  
  # Call the version specific install script
  
  exec ${OPENSHIFT_PYTHON_DIR}usr/versions/${version}/bin/install $version

  So what is the problem ? And how can I solve it ?
  thanks

• Play video files online sequentially without delay/buffering between videos

  26 février 2015, par Marko

  Is it possible to play video online that’s made of two or more video files ?

  Since my original post wasn’t clear enough, here’s expanded explanation and question.

  My site is hosted on Linux/Apache/PHP server. I have video files in FLV/F4V format. I can also convert them to other available formats if necessary. All videos have same aspect ratio and other parameters.

  What I want is to build (or use if exist) online video player that plays video composed of multiple video files concatenated together in real-time, i.e. when user clicks to see a video.

  For example, visitor comes to my site and sees video titled "Welcome" available to play. When he/she clicks to play that video, I take video files "Opening.f4v", "Welcome.f4v" and "Ending.f4v" and join/merge/concatenate them one after another to create one continuous video on the fly.

  Resulting video looks like one video, with no visual clues, lags or even smallest observable delay between video parts. Basically what is done is some form of on-the-fly editing or pre-editing, and user sees the result. This resulting video is not saved on the server, it’s just composed and played that way real-time.

  Also, if possible, user shouldn’t be made to wait for this merging to be over before he/she sees resulting video, but to be able to get first part of the video playing immediately, while merging is done simultaneously.

  Is this possible with flash/actionscript, ffmpeg, html5 or some other online technology ? I don’t need explanation how it’s possible, just a nod that it’s possible and some links to further investigate.

  Also, if one option is to use flash, what are alternatives for making this work when site is visited from iphone/ipad ?

• Find the streaming url source of an online streaming tv station to record with ffmepg

  20 mars 2016, par AHC

  I am trying to look into the javascript streaming source of the following site http://www.aztv.az/canli/aztv-canli.htm to capture the url and to record it using ffmpeg.

  My goal is to get something like this running :

  ffmpeg -i rtsp://XXX.XXX.XXX.XXX:XXX/live.sdp -acodec copy -vcodec copy c:/test_recording.mp4

  I don’t know what protocol this website uses, rtsp, rtmp, http, etc.
  Could you please help me to resolve this ?
  I tried to look into the .js file in the source of the page, but it is a bit complicated to figure it out. here is the js script.
