i.MX6Q MJPEG decoding error

Tarek — Tue, 05 Mar 2013 10:53:57 GMT

Hi,

I'm trying to decode MJPEG stream from IP camera but I'm getting VPU errors. I have enable the VPU wrapper debugging and I get this message:

The Jpeg Image must be another profile

What does this mean?

It is clear that vpu_DecStartOneFrame() is returning RETCODE_JPEG_BIT_EMPTY but I'm not sure why!

Here is the full log:

Hi Vlandan,

The video container is MKV, from our release document, mkv doesn't support MJPEG, you should find *.avi or *.mp4 mjpeg file.
