  • What is the difference between x264 and ffmpeg ?

    5 décembre 2013, par user3067233

    So I'm trying to compile the H.264 codec so that I can use it to enhance performance in NoMachine as per https://www.nomachine.com/AR10K00695

    Instructions below deal with the following possible cases on server
    host :

    Case 1 : You don't have x264 library already compiled

    Case 2 : You have x264 library already compiled

    and on client host :

    Case 1 : You have FFmpeg already installed

    Case 2 : You don't have FFmpeg installed

    Case 3 : You have FFmpeg libraries already compiled

    The weird thing is that it states that you compile x264 on the server and ffmpeg on the client. Shouldn't you have either have x264 compiled on both the server and the client or ffmpeg on the server and the client ?

    Why use two different codecs for the server and the client ?

  • Delay in video playback. Not able to identify the cause - AWS S3 region / ffmpeg / Videojs

    17 septembre 2016, par Himansu Kisan

    We are not able to identify the cause for random behavior while playing video on our website. (Sorry, cant share a link since the videos are for registered users only)
    The videos sometimes plays instantly and sometimes it takes over 1 minute to start. Not sure what we are doing wrong.

    We are using AWS S3 Oregon region (not the closest to target region, but it is cheaper) to store video files.
    The video files are encoded using ffmpeg. Below is the syntax

    ffmpeg -i input.mts -codec:v libx264 -threads 4 -movflags +faststart -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale="trunc(oh*a/2)*2:720" "output.mp4"

    ffmpeg -i input.mts -codec:v libvpx -threads 4 -quality good -cpu-used 5 -b:v 500k -maxrate 500k -bufsize 1000k -qmin 10 -qmax 42 -vf scale="trunc(oh*a/2)*2:720" -codec:a libvorbis -b:a 128k "output.webm"

    On website, we are using Videojs 5.10.8.
    Below is the code snippet

     <video class="video-js vjs-default-skin vjs-big-play-centered" preload="none" controls="controls" poster="abcd.jpg" style="width:100%;height:100%;min-height:360px;" data-setup="{&quot;autoplay&quot;:true}">
    
<source src="abcd.mp4" type="video/mp4"></source>
    
<source src="adcd.webm" type="video/webm"></source>
    
<p class="vjs-no-js">

    What are we doing wrong ? Please help us out.

  • lavc/libaribb24 : add error handling to region handling

    lavc/libaribb24 : add error handling to region handling

    Fixes some rather embarrassing mistakes that somehow passed my
    
eyes.
    

    * Now catches if memory allocation has failed during bprint usage
    
  by checking av_bprint_is_complete().
    
* Now catches if adding an ASS rectangle into an AVSubtitle failed.
    
* Returns AVERROR_INVALIDDATA if we get an invalid region buffer
    
  length.
