Hello, could anybody confirm that there is no full/working support for USERPTR in current videobuf-core? That is the conclusion I came up with after a more thorough investigation. I am currently working to fix that, and will hopefully be posting patches in the coming days/weeks. Is there any other development effort underway related to this problem?
