[solved] Can't play video in debug (1 Viewer)

Did you search the SDK folders for the streams.h file?
If no, you should.
If it's not there, I don't know what to suggest. I know what must be done for XP, and the Wiki explains for W7 and W8/8.1, but not W10.
If it's there, you probably have not created the required environment variables. Note that the EV definitions may need to be modified given that you're using W10. Again, sorry I can't help you with that.

In fact, a quick internet search yields:
https://social.msdn.microsoft.com/F...ows-10-sdk?forum=windowsdirectshowdevelopment

You probably should not download/install the linked SDK because it's for .NET 3.5 (MP uses .NET 4). Maybe in that case you could try to follow the Wiki instructions for W8.

I have the missing header in that 7.1 SDK. I have the required environment variables.
The problem seems to be coming from the fact that the newer Windows 10 SDK, which I'm probably targeting, does not include the samples we are trying to include.
Thanks for sharing that link. One guy there seems to have found the proper solution:

Regarding your build advice, I got burned by environment mismatches several times, so I now include the DirectShow base class source files in every DShow project I build. That way, I know the properties all match.

That would make sense since those are samples apparently.

 

[mm1352000]

We also include the base classes in our repo. They're not samples. The samples are something completely separate. Both the samples and our filters require the base classes in order to compile.

 

[Stéphane Lenclud]

We also include the base classes in our repo.

I see, streams.h is also in our repo. So why do we try to include the version from the SDK?

They're not samples. The samples are something completely separate. Both the samples and our filters require the base classes in order to compile.

So why do they live in a subdirectory from "Samples" and why is the full source code provided? Then again I know next to nothing about DirectShow so I'll take your word for it.

 

[mm1352000]

I see, streams.h is also in our repo. So why do we try to include the version from the SDK?

I've looked at the project config, and I don't think we do. The DShowHelper project config for the debug build says:

<AdditionalIncludeDirectories>$(SolutionDir)baseclasses;$(WINDOWS_SDK)Include;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>

streams.h should be picked up by $(SolutionDir)baseclasses.
Did you try to open and build the DShowHelper project by itself?
If yes, that is your mistake.
You must open and build the DirectShowFilters solution (DirectShowFilters\Filters.sln), not the individual projects.

So why do they live in a subdirectory from "Samples"...

Ask MS.
(Sometimes MS do confusing things. )

...and why is the full source code provided?

Again, you'd have to ask MS.
Perhaps it's necessary to be able to build from source in order to target specific platforms or build specific types of binaries (ie. MBCS, non-MBCS).

With this stuff it's often easier to just follow the instructions or do what everybody else does rather than try to understand. That's what I do.

I would love to do that but since my build is not working I have to look into it.

I've looked at the project config, and I don't think we do. The DShowHelper project config for the debug build says:
var rm = "read_more ..."; var o = "... Read Less"; var adjustheight = 20; // 20; // streams.h should be picked up by $(SolutionDir)baseclasses.
Did you try to open and build the DShowHelper project by itself?
If yes, that is your mistake.
You must open and build the DirectShowFilters solution (DirectShowFilters\Filters.sln), not the individual projects.

I was using the DirectShowHelpers solution rather than the Filters solution and the path to baseclasses is wrong there.
Though it should work with Filters as you are pointing out.

So building the Filters solution from VS 2013 gives me the following errors:

True... but it seems most of the problems you've run into so far could have been avoided if you'd used the build scripts. For example, there would be no confusion about the DShowHelper solution, and so there would also be no confusion about streams.h and SDKs.

I was using the DirectShowHelpers solution rather than the Filters solution and the path to baseclasses is wrong there.

Okay. For the record: I do not maintain DShowHelper, but AFAIK the DirectShowHelpers solution is not used.

So building the Filters solution from VS 2013 gives me the following errors...

There are only 3 errors there, and they all look approximately the same. All related to YASM. The obvious question would be: have you followed the instructions in the wiki that relate to YASM?
http://wiki.team-mediaportal.com/1_...ding_MediaPortal_from_source/1_Git_Setup#YASM

If not, it's no surprise that you're getting the errors.

I have to go to bed now as it's 00:45 here in NZ. Unfortunately I'm going to be away from home and fully away from keyboard from tomorrow lunch time for approximately 24 hours. If you have further problems/questions, I'll try to reply before I leave. However I still have preparation so I cannot guarantee anything until I get back. Sorry about that. Hopefully other devs will be able to step in if you get stuck again. Good luck!
