Live TV with Qt

Comments

GTO India - I was just a lay man or very new to Qt but worked on symbian c++ before

Hi,

With this application Iam able to learn Qt and implement my first and best project in Qt without having any prior knowlede.

This application is very much easier to understand if we are able to install Qt 1.1.2 SDK succesfully. For any person working on Qt

i would suggest to take this project as first step and start implemnting your required changes.

Description

This is a Live Streaming Application which launches the default Real Player of the device and plays an RTSP Streaming Link. I will show you how to play You Tube Videos (Live) in this article. You can also try to play Live TV Channels using other RTSP like rtsp://server/domain/tvname.sdp

How to start

1. Lets create a text file and paste this link rtsp://v4.cache4.c.youtube.com/CkELENy73wIaOAnGbz7NeJeeixMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoWglDbGlja0xpbmtgqZW17Zb0qbRKDA==/0/0/0/video.3gp
2. Save the text file as youtube.ram
3. Create a folder with a name channel
4. Copy the file youtube.ram to channel
5. Create a New Qt project, and named as LiveTVQt
6. Copy the channel folder to LiveTVQt ( project directory).

LiveTVQt.pro

Use the DEPLOYMENT keyword to copy files into the package file and to the device. All the files from the channel folder are copied into the package. When the package is installed on the device, the files are stored on the device's C:\Data\System\LiveTVChannel folder.
