Mosaic/grid view of RTSP streams with ffmpeg

Finally found a solution for grid/mosaic playback of RTSP streams.

ffmpeg -rtsp_transport tcp \

Installing Plex Media Server on a remote host

Finally nailed it. I installed Plex Media Server on a remote host and after visiting the http://REMOTE_HOST_IP:32400/web I had no add server option.

In a forum thread I found the add server URL part, just add #!/setup http://raspi:32400/web/index.html#!/setup
But I got Setup is not allowed for shared servers. error

Setup is not allowed for shared servers.

I ended up with port forwarding to the remote host
ssh -L 32400:raspi:32400

To be able to add server I had to connect to localhost http://localhost:32400/web/index.html#!/setup

Video cutting from start to end time using ffmpeg

Sometimes I need pieces from movies to upload to YouTube for example.

It’s possible with the following nice oneliner:

ffmpeg -i IN.mp4 -ss 01:12:55 -t 35 -async 1 OUT.mp4

The solution came fromĀ http://stackoverflow.com/questions/18444194/cutting-the-videos-based-on-start-and-end-time-using-ffmpeg

Convert iTunes DRM .m4v into .mp4

  1. I used Windows 7 64bit and downloaded iTunes 12.1.2 because the need to login and play the purchased TV show.
    For video converting I found Wondershare Video Converter Ultimate.
  2. After adding a video into Wondershare it complains that the movie is DRM protected so after click OK a browser window should open to download Free DRM & DVD Protection Removal Plugin from http://www.protectdvd.com/
  3. After installing the plugin and rerunning the converting procedure in Wondershare it worked.
