Compress 10 to 20 highly redundant images using a compression library?

Question

I am going to generate images once a minute or so from a low resolution camera. I would like to take 10 to 20 images and compress them for transmission over a channel with limited bandwidth. I looked at using x264, but it feels like a kill.

Given that my images are 320x240, with a high level of redundancy between frames, what would be the best way?

Encoding does not have to be particularly fast, the more it finds a balance between difficulties when deploying on an embedded device and reducing the overall file size.

I will have full control over the viewing software, so using a modified version of some compression scheme will be fine.

I will use freeRTOS

Answer 1

Is there a libavcodec port for this device? I think it has a built-in h.264 encoder. I don't think h.264 is crowded.

Define limited bandwidth. If you have enough bandwidth to transmit 1 bit per pixel (it will be 160 bytes per second at a frequency of 1 frame / min), you do not need to go beyond jpeg. If you have even less, then temporary compression is guaranteed (some kind of MPEG).

Before you perform porting, you should simply check if redundancy really helps to reduce the transmission speed.
