Hi All,

I am using "imxv4l2sink" and I see that its not showing prerolled frame. It only played framed decoded after going into playing state. Can you please help to fix this ?

Hi igorpadykov,

Thank for the response, but there is no mention of "imxv4l2sink" in the link. I think, implementation is lacking this feature. Can you please help.

Hi igor,

Please help with this issue. It looks like preroll frame rendering mechanism is missing in "imxv4l2sink". If so what can be done here ?

Hi igor,

The issue can also be reproduced in another manner. If we use "imxv4l2sink" and pause the video, in PAUSE state if we seek, frame will not be updated. But if we play, playback will start from the seeked position.

Hi igor,

I was able to download the user guide from the below link. There is nothing which addresses this issue. We are using the same way its mentioned there.
