Perhaps the problem is the encoder.  Can you try out other encoder? can you try to encode other format?

Under imx6 platform, I have used GStreamer to capture images, take a look of this document

Hi shanmugamsundar, I did not get your point. what do you mean by 'hard ware connection'? One the image is encoded? can you decode and display on the board? can you do the same on your host machine?

Hi

Leonardo Sandoval Gonzalez,

I am working on iMX 53 and Android 2.3 build,

I need to use the VPU to decode the jpeg image (software decoding works fine but going for VPU decode for better performance)
I had checked the mxc_vpu_test and the config files, there are options for decoding movie formats like MJPG , MPEG etc  in config_dec. But I could not see any options for JPEG decoding ???

So is it possible to use VPU for image file (jpg | bmp | png) decoding efficiently ?
