Does CoreAAC v2 decode AAC HE+PS?

Is the graphic on the CoreAVC website a condom with a face, ears and arms on it?

Funny, yesterday it had a different symbol than that "copy controlled" one. But i also noticed the condom-shape.

Sounds like an excellent plan

Timecodec.exe, while a nice idea, is useless at telling you if the decoding framerate dips below the source video framerate.

For example, Timecodec.exe tells me that the Marie Antoinette 1080p trailer plays back at 34 frames per second. However, when I play it back in realtime, I can see frame drops here and there - obviously in some spots my PC cannot keep up. I would like to know if there is a tool out there that can tell me what the MINIMUM framerate achieved was?
Maybe you'll try to use actual renderer in it? (see "dfps" at picture below)

dk75, I did that - the dfps of 34 was with VMR9. It does NOT tell me that dropped frames would result, like it did when I watched it in a real directshow player.

VMR9 is too much depended on the player, also I think it'll have less cpu usage with smaller image. And if you try VMR9 in timeCodec and then use MPC renderless e.g. to play the video it's only natural that it varies, MPC VMR9 renderless is dependant on the players additional processing too, especially software scalers etc.

Then use ZoomPlayer and during playback hit "I" - you will see actual FPS.

dk75, so what you are saying is there is no way to determine if you get framedrops or drop below source framerate without actually monitoring the fps manually? Is that "actual FPS" an average or instantaneous?

IF the above is an average, what you propose is useless for the Marie Antoinette 1080p trailer on my rig - it takes the VMR9 renderer tens of seconds to settle the framerate, and by that time the critical high-bitrate section at the beginning has just been played - and then the framerate holds steady even when one or two frames gets dropped because it is an AVERAGE framerate, not an instantaneous one. Make sense?

So then there is no automated way of benchmarking video performance including minimum framerate achieved?

videomixer9, that's okay - I'm merely concerned with raw codec performance, not whole playback chain performance.

This is like those quick-and-dirty videogame benchmarks - "Oh look, Doom3 averages 60 frames per second on this rig!" - ignoring the fact that key scenes in the game dip below 10 frames per second! Playability? Who cares?

EDIT: Oops, removed a sentence that didn't make sense.

Hopefully not. It should be paid and come with any purchase of the video decoder.

I wouldn't mind CoreAAC being included, but please make sure it's an optional install as with Haali...

BTW it's a great piece of software you guys have. Very fair pricing. Thumbs up!

CoreAAC v2.0 would be available for CoreAVC users who already paid for any version. It would also be in our 'Core Media!' playback bundle... and yes would be set as an optional install.

if you use media player classic (mpc) you can enable a statistic display in the view menu. there you can see current bitrate, average bitrate, dropped frames (accumulated), average fps and so on. maybe this is what you are looking for...

Just as an FYI, you may have a slight problem with your current download system. In my registration email, it said "In the mean time, you should keep a copy of this file somewhere safe, as downloads are automatically deleted after 7 days." Just tried it again and it still works. Will likely be fixed with your new accounting system, yes? So, it may not matter to you, but I thought I'd mention it.

This is tougher than I thought - I could not get Zoomplayer or MPC to report any dropped frames, even if I do something insane like run Cinema Craft Encoder at the same time (at a higher priority too!). It looks like the video will slow down and the audio will stutter - hence, no dropped frames!

So, your suggestion DK75, of using the Information dialog box in Zoomplayer is the best bet - it reports the frame rate that is updated quite frequently and isn't a longrunning average. Dips to 19 fps on this P4 3.0 GHz PC with a crappy ATI card in it.

Thanks dk75.

Correct... we also just added the delete script and have change it to 24 hours.
