Running the Demos with the PC Host Application
3-10
After you click Play , the Progress bar shows the percentage of the
video file that has been consumed by the target's video decoder. The
K-Bytes fields show the number KB of video and audio processed
thus far. The Time field shows how long the application has been
running in Decode from File mode.
11) If you select "Encode to File" mode, you can select a file location to
store the encoded output from the target-side application.
To select a video output file, click the "..." button next to the Video
field. Browse to the location where you want the file stored. The
C:\dvsdk_1_xx_xx_xx\data\video folder is the default. Type a
filename and click
Save . No file extension is added automatically.
You might want to use .h264 or .mpeg.
To select an audio output file, click the "..." button next to the Audio
field. Browse to the location where you want the file stored. The
C:\dvsdk_1_xx_xx_xx\data\sounds folder is the default. Type a
filename and click
Save . No file extension is added automatically.
You might want to use .g711.
Note that the output video and audio files generated are "raw" files.
These do not contain header information, just raw H.264, MPEG4,
and G.711 data. You can download the free VLC Media Player utility,
which can convert "raw" file to standard media files.
You can set a time limit for encoding in the File Output area. This
prevents your disk from filling up if you leave the application running.
The default is one minute. Be aware that the files generated are quite
large, especially if you extend the time limit.
The K-Bytes fields show the number KB of video and audio
processed thus far. The Time field shows how long the application
has been running in Encode to File mode.
12) Click Play to begin the demo and Stop to halt the demo.
