HD Playback Reports

Playback of HD content - User Reports

This page is for playback reports regarding High Definition Content. This page will serve as a resource for users in selecting hardware for their MythTV systems.

How to produce information for this page

Paste the following into a file (eg, hdplayback.sh), chmod +x the file, and run it on a file known to play back perfectly on a given system (eg, ./hdplayback.sh moviefile.mkv). It will produce an output file called hdreport.txt. hdreport.txt is in wiki format. Edit this page, find the most suitable position in the table to place the data (by CPU spec), and paste the output there. Edit the "Comments" section to share any special command line needed to get the program to play smoothly.

This script requires mplayer to run properly.
