• nginx-rtmp with gcsfuse ffmpeg permissions

  8 août 2021, par fitzmode

  I'm using nginx-rtmp-module in a Docker to record rtmp streams into a Google Cloud Storage bucked mounted with gcsfuse.

  


  While I'm able to record the stream into .flv, using exec_record_done to convert the files to .mp4 results in a .mp4 with 0 byte size. Attaching a shell to the Docker container and executing the ffmpeg command produces the .mp4 file that works as expected. I suspect this may be an issue with a discrepancy between the nginx user permissions and ffmpeg user permissions.

  


  user nginx;

worker_processes auto;
rtmp_auto_push on;

events {
    # use epoll;
}

rtmp {
    log_format stream '$remote_addr $app $name $command $bytes_received $session_time';
     access_log on;
    server {
        listen 1935;
        listen [::]:1935 ipv6only=on; 
        application live {

            live on;
            record all;
            record_path /opt/static/videos;
            record_max_size 100000K;
            record_suffix %Y%m%d%H%M%S.flv; #Colon permitted in Linux Filesystem.
                            
            
            exec_record_done ffmpeg -i $path -codec copy /opt/static/videos/$basename.mp4; 
           
        }

    }
}

  How can I ensure ffmpeg has the correct user permssions to read and write to the mounted folder ?

  


• Understand your visitors by seeing where they click, hover, type and scroll, and replay their actions in a video

  18 mai 2017, par InnoCraft — Plugins

  Hi, this is Mike from InnoCraft, the company of the makers of Piwik Analytics which is used by over 1 million websites and apps in over 150 countries.

  I’m very proud to introduce you to our Heatmap & Session Recording feature which lets you analyze your visitors’ behaviour on a whole new level that was not possible before.

  With Heatmaps you can see where people think something is clickable but it is not, how far down the page do they scroll, whether they see your important buttons and Call To Actions, or even whether you can re-position your page layout to put the important content in more visible places. Both the mouse movements and all clicks are recorded and viewable on these new beautiful heatmap visualisations.

  With Session Recordings, you get to see a video showing exactly what a visitor did on your pages, including all mouse movements, scrolls, text typed in the keyboard, and more. Using these recordings you can improve the usability on your website, replace costly (and less effective) eye tracking sessions, and you can now see exactly what problems your visitors experience or how they behave on your website. This gives new insights and ability to understand what your users think.

  -> Read the rest of the story on the Heatmaps & Session Recordings Marketplace page.

  What does the new Heatmaps reports look like ?

  Here is below just a little preview of the new Heatmaps reports.

  1) Mouse move and Click Heatmaps

  

  2) A Scroll Heatmap

  

  What does the new Session Recording look like ?

  You can replay videos of exactly what your users did on your websites including mouse moves, scrolls, typing in forms, and more.

  1) Listing all recorded video sessions

  

  2) Playing a recorded video session

  

  Where do I get Heatmaps & Session Recording for Piwik ?

  The new premium plugin is available on the Piwik Marketplace :

• Android mp4 remove rotation and rotate the video stream

  4 mars 2015, par Mathijs Segers

  I’m having some issues trying to remove the rotation value of Android video’s.
  For some reason convertion tools in the cloud cannot seem to handle android’s rotation value correctly. f/e I have a portrait video recorded in 1080x1920 (so the file’s headers tell me it’s actually 1920x1080 with rotation : 90).

  So now I’m trying to convert these video’s to an actual 1080x1920 format when they have this rotation value but i’m kind of stuck, probably using the wrong search terms on SO and Google.

  In the hope of making things clear I’ve actually added some ffmpeg libs to android following these steps, of course with some changes to parameters. I’m building this on a Mac and this all works fine now.
  http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/

  Now the following, I have no real clue how these libs work and how to use them or which I actually need or if I even need them at all.

  Is there anyone who can point me in the right direction of solving my issue ? Basicly the video’s are on my android filesystem and I can access them fully, before uploading I want to check the values and remove and rotate the video’s if needed.
