Video play test [VIDEO]

Top  Previous  Next

This test allows video files to be played as a BurnInTest test. This allows for the detection of numerous error conditions that a PC might exhibit, from lack of media codec support, playback errors and dropped samples (reduced quality due to the PCs inability to process the video quickly enough) and Bit Error Rates. From the Video Playback Preferences window, up to 4 video files can be selected for playback, with each video being played in turn (1st, 2nd, 3rd, 4th, 1st etc). The test can be run across multiple monitors.

Video files come in a number of different file formats and within these file formats, video and audio are encoded using different compression methods.

The file formats supported include:

Audio-Video Interleaved (AVI)
Motion Picture Experts Group (MPEG, MPG)

The Video Compression formats supported (where installed) include:

Cinepak
Intel Indeo
DivX
MJPEG
MPEG-1
MPEG-4 video: ISO version 1.0 , Microsoft version 3
Microsoft Windows Media Video codec version 7.0

MPEG-2 is not supported.

 

Note: Each of the above formats are registered trademarks of their respective owners.

 

Sample test videos are available from the PassMark Web site.

By default, a test window will be opened when the tests are started. This will be placed on the primary monitor and sized with width based on the BurnInTest test window size and height such that the aspect ratio is maintained (i.e. so it is not squashed). The window be may moved,  resized or made full screen.

With BurnInTest Professional, the user can change this default by increasing the number of test windows from 1 up to 4.  The test window sizes can also be changed from 160x100 up to full screen. The test windows can be placed automatically on the primary monitor, or automatically across all monitors (up to 4). When the test windows are of the default size (300x200 - with the height adjusted to maintain aspect ratio) and placed on the primary monitor, they will be arranged below the previously opened test Window (as is the case with the other test windows). When the test windows are not the default size, or are automatically placed across the monitors, then the test windows will be centered on each Monitor. If there are more test windows that actual monitors, then the test windows will be wrapped back to the first (then second etc) monitor and there will be a slight offset of the test window.

The title bar will show the native video size (Width x Height). Bit Error Rate will be logged to the detailed log, where available and greater than 0.

The number of operations will indicate the number of seconds of Video played. A cycle represents each video file that is played, e.g. if Videos 1,2,3,4,1,2 were played, this would represent 6 cycles.

Duty cycle sets the amount of delay between each of the video files played.

Error reporting may be configured not to report reduced quality of Video playback (dropped samples) errors. This can be achieved by editing the Error Classifications file (BITErrorClassifications.txt) for Error Number 182 to NONE. For example, changing the line from:

182,"Video Playback is dropping samples",WARNING,

to

182,"Video Playback is dropping samples",NONE,
