Martin, I'll update you on this in a new thread soon. We had been running into the age old problem of plugging one hole and having two more leaks spring up. We are finally onto something that seems to be fixing everything. It's a simple code change in HPD. Rich Sent from my iPhone > On May

Hey Richard, I'm going to need some time, peace and quiet to get to the bottom of this. Which means not in the very near future :) But I'm very interested in getting this to work. Can you post some failing codes/OOTs somewhere for me to start testing? M On 22.05.2015 15:22, Richard Bell wrote: >

Martin et. al., I implemented my own block that produces a trigger signal when a specific tag is encountered, and I feed this into the detect port of the HPD block. This is an attempt to overcome the tag trigger issues we've been having in this email chain. The trigger_tag block simply outputs zer

Yes I will file a bug. We put a tag_debug block right before the HPD input. The tag debug stdout statements continue, while the get_tags_in_range function of the HPD block returns none. We will continue debugging this to see if we can learn something more concrete. The time it takes the flow

This is interesting, and kinda serious. Also, we've had reports that tags go missing in the past, but it's something that's hard to verify. How did you confirm the input stream is correctly tagged? If get_tags_in_range isn't finding tags that it should, that is most likely the issue you're seeing

Hi Martin, Sorry for the delay in response. We have been able to put some time into debugging this issue and here is what we've found: 1) We have confirmed that the input stream to the HPD block is correctly tagged when the block freezes. The tags we set as "trigger tag" in the block are on the i

Hi all, I'm working on an incredibly annoying issue related to my use of the Header/Payload Demux (HPD) block. I think it's related to a buffer overflow at some point, but I'm having a really hard time coming up with a proper debug strategy to nail this down. What I'm seeing is my data streams fr
