**c/c++/VC++ expert for 1 days task to make small MBR/ABR/ Transrating update to h.264 and AAC/GSM** **video encoding and streaming client server and viewer application** **similar to flash m#edia e#ncoder/ W#owza/ flash media player. **
## Deliverables
Existing qualities of the current APP:
- Supports rtsp, http, rtmp, h264 and webm streaming.
- Supports professional camera through video capture cards/ devices like ezcap dc60.
- Great a/v in sync quality for small as well as large video resolutions.
- Live video Delay is <2 second and supports network latency as high as 800ms.
- Video does not freeze or buffer and there are no distortions.
- Bandwidth use is between 110kbps for CIF (352x288, 30qmax, 20fps), and around 500kbps for 1280x720 (30qmax, 20fps)
- Works through firewalls and proxies as it streams on port 80
- CPU usage on encoder/viewer not more than 30% for core 2 duo, 1GB box.
TODO: Enhancement - Keeping the existing qualities same, enhance encoder client/server/viewer so that it can support
Transrating: Multiple bit rate/ adaptive bit rate support following way:
Encoder will stream at a selected or lesser (automatic) bitrate(s) depending on either user selection or based on available bandwidth (Through network algorithms (already built in current application which could be used as reference/ enhanced)) with media server. Server will make the stream at same or lesser bitrate to the individual viewers based on following three conditions: 1. Viewer specifically makes its preference known to the server at what bitrate they would like to view the stream (manually/ automatically through network detection) 2. based on available bandwidth , identify viewer capability and render same as encoder or lesser bitrate stream accordingly. 3. As per the bitrate(s) Configured on Server for the given stream.
to be given: all the vc++ VS 2008 compiling and running source code of the existing client - server - viewer project.
Deliverable: VS 2008 compiling and running application as mentioned above.
Testing:
1 - Start the server.
2 - Start encoder in adaptive / multiple bitrate mode.
3 - Start viewers from different bandwidth connections ranging from 50kbps to 1mbps. And observe that instead of buffering or video stuck...low bandwith users watch the video at lower quality and high bandwidth users watch the video at higher quality flawlessly. And test the application as per the other required parameters.
Let me know if any queries.
