Regarding MJPEG Video decoding

Ronak Desai

Hi, 

We are facing a strange issue. In our use-case we are decoding MJPEG data and providing it to DEI for scaling and then providing it to display.

But, when we provide a MJPEG file encoded using ffmpeg then the pixel format is yuvj420 and then we provide it to decoder and we get colorless video on display. But if we provide a MJPEG input with pixel format yuv420p then we see proper color on display after decode.

We checked that decoder link output is yuv420 so does it mean that decoder is not capable for doing pixel conversion from yuvj420 to yuv420.

We are using DM814x platform and DVR-RDK-4.1.

Thanks,

Ronak
