Hi, Thanks, i will try to write the YUV image to the framebuffer to see I fit is correctly decoded.
The boe.yuv file is created by decoding the default frida image. So the resolution should be right. Is it necessary to load the cmemk.ko file with special pool sizes? And is this the only module I need to run the code/decode examples?

This boe.yuv example that you are using, how to you generate that yuv file? On my board I can feed the frida image provided on the latest codec release into the encoder and decoder without problems. Keep in mind that these examples had hardwired resolutions in the code, so if you feed anything unexpected, they crash. Regards, Diego Dompe RidgeRun Engineering.
