View Full Version : Pause every 5 seconds streaming to iPad 2

Well this started with WinTV 2.5a. Every 5 seconds the stream pauses for a second or two and continues on. There is plenty of CPU horsepower available (1090T 6 core) and cpu usage is roughly about 25% when it is transcoding. I'll attach debug logs in a bit. Have to reboot first.

Here are the logs (2048 seems to work ok but the picture is "jumpy")

What bitrate/resolution are you using? If you reduce it, and it starts working, then it's almost certainly a case of either the CPU or networking not being able to supply data fast enough.

Previous versions transcoded fine at that bitrate and the wifi network hasn't changed either. This just started after going to WinTV 2.5a.

Streaming the raw stream via http has no issues playing in xbmc via wifi either.

The processor as well is able to keep up fine. Same issue happens even in a i7-3930k.

EDIT: Setting it to the highest setting for the new iPad offers flawless playback (even though it is only an iPad 2).

Sorry, I dont know. If you reduce it and it starts working smoothly though, then I'm pretty sure it'll be a CPU or Networking bottleneck as I mentioned above.

I've isolated it down to any scaling that seems to be the cause (bitrate does not matter). Sending any native resolution (custom Extend profiles for transcoding in 720 and 1080) results in smooth playback (again this did not happen on earlier versions of WinTV and you can't get much more of a cpu and during transcoding the cpu load is pretty light even when scaling).

I should also add that on both machines that this was tested on had fresh Windows 7 Pro 64 installs and the only application installed is WinTV and Arcsoft. All updates are applied to windows.

Well, ghosted back to a clean install and installed 2.4d with the 2.5a drivers for the colossus. Zero issues at any bitrate or resolution.
