Capturing an iamge and Recording a video from Camera and Encoding Camera's O/P

[nikhil29]

Hello NXP

I'm working on a camera related project [ Using C Programming Only ] for that i need your help.

1]  to capture an image and record a video and then encode the same.

2]  after that i need to downscale that image and send to TV [ Host ].

So, to execute the above things could you please share some methods / tools / libraries / techniques to do the same.

Q1 : If i could use GStreamer, then i want to know the difference between how to capture / record    and  encode using GStreamer plugins  ??  [ Difference between record / capture and encode via GStreamer ]

Q2 : and for downscaling could i use OpenCV [ for C programming only ]  ?? 

If yes, then send me PDF / tools / libraries / methods realted to OpenCV

Thanks

Nikhil

Amazing post! 

C programming is super important for shot blasting machines. It helps control parts like conveyor belts and shot flow, automating tasks to work without human help. It also gathers data from sensors to monitor the machine's performance and creates easy-to-use screens for operators. Plus, it connects the machine with other systems for better workflow. Overall, C programming makes shot blasting machines efficient, reliable, and user-friendly!

Hi nikhil29

It will be supported after public launch.
