Dropped frames with Decklink and Intensity and Adobe Flash Media Live Encoder
We have been experiencing a massive amount of dropped frames in Adobe Flash Media Live Encoder (on Windows) with the Intensity and DeckLink SDI. Everything is flawless for the first couple of minutes and then drops down to 5-10fps.
I suspected that perhaps the input processing of these cards may have something to do with this, especially the Intensity’s, as afaik its done in software (and the DeckLink’s in hardware?) but ruled this out as even with 480i input the same thing happens.
For anyone interested, I can confirm that 1080i/720p input works in FMLE 3.1 (which isn’t out yet but I’m a beta tester), however it doesn’t mean much with these horrible frame drops. An FMLE developer in the Adobe beta forum mentioned that these issues may be due to a problem with Timestamps. I do not know how this carries over to the Windows side of things as DirectShow and QuickTime are two different animals, but it’s worth a mention.
I would really like for someone from Blackmagic to shed some light on this. Thanks in advance!

Jay,
i tested the Decklink Studio on a WinXP Pro (32-bit) system with the final release of the live encoder and everything is working very well. Could you tell me on which platform you have made the test ? I would give that also a try. -

hi
i did have very long time the same problem with Adobe Flash Media Live Encoder
I could never stream more then maby 2 min and then the fps start to drop down more and more
i did only get the streaming work with Wirecast 4.0 and the Newer Vidblaster with Camera II
but i did fix the problem now with a program called DPC Latency Checker and the source to the problem was PC Probe2 it´s a motherboard temp and cpu monitori did have 4000 latency so that was the problem
so now all works great no more fps drops 🙂hope it helps others if they have Similar problem
