Speaking about programs, i was meaning to improve support for that at some time in the future, but i'm not sure about the best approach. The easiest solution would be to just show all streams, and add a PID identifier to the stream selector (like MPC-HC Mpeg Splitter) Additionally, i could add a 4th "stream" category which lists the programs. Selecting one of those programs would then switch all 3 stream types to that program. This allows full manual stream control, as well as an automated way to switch all streams at once. From the implementation stand-point, this is also the easiest solution. Thoughts?

There is no "last one", its one total idea.
Show all streams of all programs, and in addition show "virtual" streams that switch audio/video at the same time.

Yes for the additional "virtual" streams cause let's faced when switching programs in 99.99% of the time we need the both new video and audio streams

what's the point in showing all streams from all programs at the same time? Personally I think it will be better to just show a list of all programs and only the streams that belong to the currently selected one. Does anybody need picture from one program and sound from another? When?

Not to mention that players may extract the available streams at start and never update their list later on, because there is no situation right now where it would ever change. Hiding information from the user is usually not a good way to go, maybe a file is just broken and the streams of all programs are meant to go together, it just adds flexibility to the whole thing. Granted if you have a file with several programs, the list may get long, but i really haven't seen files with more then 2-3 programs in them.

I see - it's more like a technical issue.
I just thought it would be better to mimic the way that TVs and STBs work - they offer you only the streams that belong to the currently selected program despite the fact that there are more programs/channels on the same transponder ... up to 7-8 different ones) I think multi-program/channel files are produced by recording the full transponder stream. This will lead to 6-8 channels in the same file (at least that's the average number of SD channels we have here). Multiply this by 2-3 and the result will be something ~15 ... which is not that bad. I think I can live with the solution you offer.

I did some testing on IvyBridge today.
System: * CPU: i7 class engineering sample (E0) @ 2.6GHz. * DDR3@1333 sodimm. * Window 7 * 2712 graphics driver * ZoomPlayer * CoreTemp * LAV splitter * Decoders: LAV 0.50.2 and my own latest ffdshow build. Good news: * Managed CrowdedRun (4K@50fps, ~122mbps) with 30% CPU@3.2GHz using both ffdshow and LAV. libavcodec (ffdshow) took 85% CPU@2600 (jumps to 2700). * This clip is the worst case scenario - very high bitrate, high resolution, high frame rate - stresses all the subsytems (memory, decoder, CPU). Most 4K clips have 1/4 of the bitrate and half the frame rate. * Other clips played fine no surprises so far. * A transposed 720p clip (720x1280) played very well. SandyBridge's QS can't play it since the line count is >1080. The bad news: * The reference board used didn't have proper cooling and the CPU hit 103C (SW or QS). At these temperatures it activates throttling to cool itself down. This might explain the high CPU usage. I need to rig it with a better fan and test again. Even with these far-from-optimal conditions the video playback was smooth. Also, started working on adding HW video processing. Some stuff already works but some issues are too severe for a proper release I'll commit to SVN my changes soon so Nev can start playing with it. Added: * Deinterlacing (half/full rate output) * Detail filter * Denoise filter Not working: * 50i sources * Telecined sources Didn't add procamp (Hue, Saturation, Brightness, Contrast) yet, I'll add it too (very simple to do but not so useful). Update Fixed the cooling solution and QS behaves the same. libavcodec now raises CPU frequency to 3.2GHz and uses all cores at 82%.

Very nice! My i7 is mostly built but I found that my mobo is defective with 2 dead dimm slots so until the replacement gets here tomorrow I can only use 8 gigs of the 2133 I got. I haven't yet tried the igpu but I want to see how good virtu is at some point.

Great news and how did you fix the cooling solution. I have hear that new i7 Ivy Bridge is higher (20°C) than sandy bridge one. Thanks.

When overclocking, yes, that's true. I had heat issues with mine for the first hour I had it running. Turns out one corner of the HSF wasn't fully seated. I'm NOT looking forward to having to move everything to the replacement mobo for that very reason.

Easy BluRay WMC playback?
Is anyone else working on native BluRay WMC playback?

Both supported. Future CPUs will also be supported.

I've verified it empirically, it ignores the control panel settings (as it should).
