image compression API?

[Dong Liu]

Hi,

Does voxl support hardware/GPU image compression? If yes, what is the API?

Thanks!

@Dong-Liu What type of image are you trying to compress? And what is the desired output format?

[Dong Liu]

@Eric-Katzfey Like the output of hires camera. JPEG will be very useful to reduce the bandwidth.

Thanks!

Does voxl-camera-server already support producing compressed image?

Thanks,

Dong

We have this project here:
https://gitlab.com/voxl-public/voxl-sdk/third-party/voxl-jpeg-turbo

that voxl-portal uses here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-portal/-/blob/master/src/video_group_manager.cpp#L390

@Dong-Liu We currently use software JPEG encoding via turbo jpeg. But there is HW support for JPEG in VOXL / VOXL 2. We have not yet looked into enabling that support though.

@Eric-Katzfey Thanks!

@Eric-Katzfey Hi Eric. The jpeg compression imposes a lot of load on the CPU, especially we're using the hires camera. Is there any way you can make the HW jpeg encoding available for us to test it?

Thanks!
