Hello Sebastian Dröge, Sudip Jain
<br><br>So its been 2 years since this post made and still i have same concern.
<br><br>Do gst-omx have now support of dma-export or dma-import (fd exported by v4l2src and used by gst-omx) ?
<br>Any discussion or ticket of patches available for this?
<br><br>Thanks,
<br>Jeegar Patel
<br><br>
