Hi All,

What is the difference between "vpudec" and "imxvudec". I also observer that some avi files doesn't work with "imvpudec" when we play using "playbin", we get below error.

But the same file works with "vpudec". Any help would be much appreciated. Am using below version of gstreamer-imx

Hi,

Am not getting what you are trying to convey. What I wanted to know was "vpudec" and "imxvpudec" both are based on vpu, are they both hardware decoders, if so what is the difference between them.

I have another question, as I mentioned, some avi files are not playing with "imxvpudec", I have highlighted the error, but they play with vpudec. Is this known issue with "imxvpudec".

-Regards,

Shiva
