DirectShow player

[trancexx]

If you have been going thru AutoItObject files ever, you have probably noticed script called DirectShow.au3. That's minimalistic player made to utilize DirectX technology.

Here's a version of that script (or the other way around) with much more features. This script will take advantage of some new features of Windows 7 system.

Windows 7 specific interfaces:

• ITaskbarList3
• ICustomDestinationList

Other used interfaces:

• IGraphBuilder
• IMediaControl
• IMediaEventEx
• IVideoWindow
• IMediaPosition
• IBasicAudio
• IBasicVideo
• ISequentialStream
• IObjectCollection
• IShellLink
• IPropertyStore
• IObjectArray
• IMMDeviceEnumerator
• IMMDevice
• IAudioEndpointVolume
• IAudioMeterInformation
• IBaseFilter
• IFileSourceFilter
• IEnumPins

Script (needed images are inline as PNGs):

DirectShow_Player.au3

Btw, ITaskbarList3 was already covered by wraithdu and Beege, don't miss their examples here and here. One more thanks to them.

...oh, and AutoItObject is here. You would need 1.2.2.0 version.

Very cool. Awesome job!

[AdmiralAlkex]

Awesomeness defined.

An angel have come to earth!

On a sidenote, it refuses to play my flv file (it shouldn't, it plays in MPC-HC and WMP). _RenderFile returns @error = 1.

How would I go on with finding out why?

[trancexx]

Workaround could be to use AddSourceFilter method and what comes afterwards, in that case.

Just looked at a posted code and I see that I've left _AddTaskbarButtons outside _WM_TASKBUTT_CREATED function. It should really be in otherwise one could end up without taskbar buttons.

Maybe I'll update the attachment.

Great stuff trancexx!

But the aspect ratio for images is not working properly.

Not properly how?

I haven't added "keep aspect ratio" option. There is only "Fit window" and "Original size". Are you saying that those aren't working properly?

I've made an update. Corrected _AddTaskbarButtons issue and added few more comments for those who would be interested in seeing how is something done in the script.

If you load an image with e.g. 1944x1296 (3:2), your script displays it with a fixed windows size (530x600) which looks distorted.

Yes, I see. It means I should keep aspect ratio in case rendered doesn't fit into the rendering area.

Ok, that makes sense. Will see how to implement that. Thank you.

[UEZ]

In line 606 ($aCall = $oBasicVideo.GetVideoSize(0, 0)) you can get the image dimension in $aCall[1] and $aCall[2]. With that information

you can resize you window appropriately.

It's little lower, inside _SetSize function.

I'm bending the image, not the GUI, if it would require to take most of the desktop area. Complete control of the win station is the most important thing, the way I see it.

Btw, how's jumplist hanging?

Cool player.

What is about additional option of it - "Capturing a Window Screen Shot" ?

Trick to enable this option was discussed here ():

Thank you

This is sooo cool!

Really nice work. Exceptional!

[trancexx]

I've made an update to show some new things that are available with AutoItObject 1.2.2.0. If you go thru the code you will see there is no use of DLLCall function. This is because it's replaced with, so called, DLL-objects to call functions from desired DLLs. Also variant data type is used (byref even) with IPropertyStore, usage of few new interfaces added to be able to have VU-meter control (or whatever that is) and so on...

Btw, these new interfaces are the same that are used for setting volume level for the system on vista and above - master volume.

[wraithdu]

Ah, that should replace my plugin quite nicely then. Odd feeling when something you've created becomes obsolete...

Yes, but you see I forgot to give you deserved credit. Your code was consulted.

I'll make a remark in the code for the next time I update the script.

[wraithdu]

Sweet, thanks. Always appreciated

[Beege]

Wow I cant belive I missed this example! This is really great Trancexx. Its demonstrates so much. Its really going to help me a lot! Thank you very much!

[WeiHeXie]

Can not play MPG video format!

[Ascend4nt]

Looking through some of the code.. wow. Some (seemingly simple) things are so complicated, but you handle them very well.

I added a call to '_UnregisterExtension()' in the _Quit() function though, because I don't want a script player permanently added to my registry, even if its pretty cool.

[trancexx]

I have it pinned to the taskbar and if I unregister I can't use it from the jumplist.

...Glad that you managed through the code.

I've added one more function to load files alternately using manual PIN manipulation enumerated with IEnumPins when GraphBuilder.RenderFile would fail. @AdmiralAlkex, would you mind trying it now for that flv? I can play "problematic" mp3 files here now.
