C1+ hardware jpeg encoder do not flushes.

[Adames]

Good morning.

I am having problem with my C1+ jpeg encoder.
I have followed the Luis's tutorial http://blog.luisdearquer.net/index.php/ ... roid-c1c1/
and encoding single image works fine. The problem is when I try to encode multiple images in loop, after 3 or 4 images in resolution 960x600 the encoder stops (The stage newer becomes ENCODER_DONE).

I have tried to use:

Code: Select all

 ioctl(fd, JPEGENC_IOC_FLUSH_CACHE,  addrInfo)
ioctl(fd, JPEGENC_IOC_FLUSH_DMA,  addrInfo) 

but without any result.

Ehen I try to again init the device, the program frezes the odroid.

At the moment i am closing file descriptor and reopen it every image. It works, however re-opening fd takes too much time to get framerate > 20 fps.

I am working under Arch linux, on Ubyntu have same problem.
I am not interested with h264 encoding, only mjpeg.

Did you try Ubuntu 18.04 image?

Yes, checked just right now. It is the same effect!

I have no idea how to keep using the JPEG encoder without reopening per every image. Sorry.
