Encoding and Streaming to your Pocket PC (7)

Can This Be Done With Video Too?
The answer is - Yes. If you’ve got a capture card or TV Tuner card in your PC, you can choose this as an input device right at the beginning of the steps discussed above. Your PC will then encode and stream the video across the wireless network. As above, there will be a lag, but the streamed video and audio will be in sync with each other, so you won’t notice it if you aren’t able to see the original source at the same time
Alternatively, if you’ve got a video file that you want to stream, you can do this as well, but the steps taken vary depending on which encoder you are using.
If you are using Encoder 7.1, choose “Create a custom encoding session” when you start the application. The New Session window will appear.

With the Sources tab selected, click on New. The “New Source Group” window will appear. By default, the video source will be set to “Screen capture”. Click on the drop-down menu and choose “Browse for file”. You can then specify your source video file. For the audio source, you can select a device or a file containing the audio (which may be the same file as that being used for the video). When you are happy with your choices, click on OK. You can add as many sources as you like, thus making the broadcast as long as the combined length of the files.
This is also an alternative way of broadcasting audio if your sound card does not have the ability to treat the output sound as a recording source.
Once you’ve chosen your source material, click on “Display Information”. As before, enter the information you want then click on the “Profile” tab. Here, pick the same profile you used when you were encoding files. Finally, click on the “Output” tab and ensure that “Broadcast encoded output” is selected and “Archive to file” is deselected. Click on OK and the encoder window will be displayed. Click on the Start button and the encoder will start encoding & streaming the output.
If you are using Encoder 9, the process is very similar. You start by defining your sources, be they files, devices or a mixture. You can also specify what the encoder does at the end of the list - stop, loop, roll over to next source or roll over to first source. Once you’ve specified your source material, you click on the “Output” tab to select “Pull from encoder”. You can then click on the “Compression” tab and ensure that the destination is Pocket PC and that the audio is “Voice quality audio”. Click on “Apply” then “Start Encoding” … and away you go.
You may be wondering why, if you are using Encoder 9, there was much talk about changing the audio settings. The reason is because, by default, the encoder likes to use a 48kHz audio format - which Pocket PC 2002 doesn’t like. With Windows Mobile 2003 device it’s unclear, whether or not that behaves the same way.
