| While the ability to stream your desktop to your TV can give you a remote monitor capability, the real value is to be able to display the output of any application on your TV, in particular the fullscreen output from any video playback application including flash videos. | While the ability to stream your desktop to your TV can give you a remote monitor capability, the real value is to be able to display the output of any application on your TV, in particular the fullscreen output from any video playback application including flash videos. |

| This means that you can now browse and display all those videos on news sites, tv network shows, movie sites, social sites or music sites etc, that are not available as rss feeds, or unencripted rtmp live streams. You can now also access and display the text info that usually accompanys many of those videos, or the subtitles that overlay videos such as hulu, or the music title/artist/album information which are not available directly to Servio online streams. | This means that you can now browse and display all those videos on news sites, tv network shows, movie sites, social sites or music sites etc, that are not available as rss feeds, or unencrypted rtmp live streams.

| To stream your desktop you need to install VLC to do the streaming, a directshow video input filter to capture the desktop area, and a directshow audio input filter to capture the sound output from the application. | To stream your desktop you need to install VLC to do the streaming, a directshow video input filter to capture the desktop area, and a directshow audio input filter to capture the sound output from the application. |
| This process has been tested and works correctly with VLC 1.1.10. It may break with other versions or nightlys so be warned. Since VLC is registry independent, you can maintain a VLC 1.1.10 version for desktop streaming, while installing updated versions for normal purposes. This Wiki entry does not address the installation of VLC. | This process has been tested and works correctly with VLC 1.1.10. It may break with other versions or nightlys so be warned.

| For the video input filter, I used screen-capture-recorder (SCR)because its free, it works, is configurable and is under active maintenance (download from http://sourceforge.net/projects/screencapturer/files/). Read the README for instructions on how it works and how to use the "Screen Capturer Recorder\configuration_setup_utilities" to set it up for your system. (Note that the author has confirmed the need to install "Microsoft Visual C++" first and that you need the Java JRE installed to run some of the utilities. See http://forum.serviio.org/viewtopic.php?f=4&t=4660&start=10.) | For the video input filter, I used screen-capture-recorder (SCR) because its free, it works, is configurable and is under active maintenance (download from links on https://github.com/rdp/screen-capture-recorder-to-video-windows-free).

| By default, it is supposed to capture the whole screen. For some reason however on initial install I got a lot of static. If this happens to you, run the "configuration_setup_utility\edit_config.bat" and set the height and width to your screen's maximum dimensions, or edit the registry keys as I did. You must however use the exact maximum dimensions recognized by your screen driver, In my case 1366 x 768 regardless of the resolution my screen was set to display which is 1280x720. (Right click your Desktop and click "Screen resolution" to see your current and maximum setable resolutions). Other users have reported the need to set the dimensions that their screen is set to display. | By default, it is supposed to capture the whole screen.

| To get Serviio to play the video stream this process requires the inclusion of an audio track, even if you do not want to hear the audio of any video you are playing on the pc. It may be possible to stream the video only, however this process does not addres that option. | To get Serviio to play the video stream this process requires the inclusion of an audio track, even if you do not want to hear the audio of any video you are playing on the pc.

| For the audio input filter, you should try the free virtual audio capture grabber device (VACGD) (download from https://github.com/rdp/virtual-audio-capture-grabber-device/downloads) however it did not work correctly for me on W7-64 and I had to use virtual-audio-cable(VAC) which while not free works flawlessly (available at http://software.muzychenko.net/eng/vac.htm). (Note that I am still working with the author of VACGD to correct my problems with VACGD..Others should try it because my problem may be with my sound card driver and not with VACGD) | For the audio input filter, you should try the free virtual audio capture grabber device (VACGD) (download from https://github.com/rdp/virtual-audio-capture-grabber-device) however it did not work correctly for me on W7-64 and I had to use virtual-audio-cable (VAC) which while not free works flawlessly (available at http://software.muzychenko.net/eng/vac.htm).

| To setup VAC for streaming, in the Sound Control panel for both Recording and Playback,(accessable by right clicking the Speaker icon in the System tray) right click the Vac "Line 1" and select "Set as Default Device". This causes the audio from all applications to be connected to the input of the VAC cable and enables the VAC cable output to be available for VLC to stream the application audio. This also disconnects the PC mic and speakers while you are streaming. For VACGD no setup is required as it will stream the default sound card output at full volume even if the speaker volume is turned off or muted. | To setup VAC for streaming, in the Sound Control panel for both Recording and Playback,(accessable by right clicking the Speaker icon in the System tray) right click the Vac "Line 1" and select "Set as Default Device".
