Hi, All!
Does anyone have a small and simple asm-example/sample for video-player mp4-files?
Thanks in advance for your answer! (https://wasm.in/styles/smiles_s/thank_you2.gif)
I wish I had an example, and indeed I had one, but it stopped working on Win10 :sad:
To give you a hint:
IMediaControl STRUCT
QueryInterface dd ?
AddRef dd ?
Release dd ?
GetTypeInfoCount dd ?
GetTypeInfo dd ?
GetIDsOfNames dd ?
Invoke_ dd ?
Run dd ?
Pause_ dd ?
Stop dd ?
GetState dd ?
RenderFile dd ?
AddSourceFilter dd ?
get_FilterCollection dd ?
get_RegFilterCollection dd ?
StopWhenReady dd ?
IMediaControl ENDS
Needs codec first:

After that Direct Sound or MCI might work.
Ciao jj2007!
Perhaps you are talking about this?
Win x64 Tutorial #37f: video-player and Component Object Model (https://masm32.com/board/index.php?msg=46945)
The program worked well in Win7-64, but stopped understanding the mp4-format and now I have problems in Win10. I thought you would tell me what I could replace it
Hello Timo! I'll try... Can you write a little more detail?
My retired Windows 8.1 Bing was able to have some additional codecs and many movies worked there.
Now MS offer that:

Timo, kiitos paljon! (https://wasm.in/styles/smiles_s/thank_you2.gif)

Hi
Mikl,
I installed the Win10 codec from https://www.windows10codecpack.com (https://www.windows10codecpack.com/), and now it works (I recently switched from my old Win7 notebook to the Win10 notebook I bought over a year ago, so certain things stopped working, as usual...).
Here is a central piece of code (the complete program is too chaotic to be posted here...):
IGB STRUCT
pigb dd ? ; --- current video ---
pimc dd ? ; IMediaControl
pimx dd ? ; IMediaEventEx
piba dd ? ; IBasicAudio
pims dd ? ; IMediaSeeking
pigw dd ? ; IVideoWindow
IGB ENDS ; v v v expands to AM_SEEKING_NoPositioning etc v v v
Enum #AM_SEEKING_, 0:NoPositioning, AbsolutePositioning, RelativePositioning, IncrementalPositioning, PositioningBitsMask, SeekToKeyFrame, ReturnTime, Segment, NoFlush
...
invoke CoCreateInstance, addr CLSID_FilterGraph, 0, CLSCTX_INPROC_SERVER, addr IID_IGraphBuilder, addr igb.pigb
.if !eax ; create a new filter using IGraphBuilder
xchg eax, ebx ; flag
or ebx, rvCoInvoke(igb.pigb, IGraphBuilder.QueryInterface, offset IID_IMediaControl, addr igb.pimc)
or ebx, rvCoInvoke(igb.pigb, IGraphBuilder.QueryInterface, offset IID_IMediaEventEx, addr igb.pimx)
or ebx, rvCoInvoke(igb.pigb, IGraphBuilder.QueryInterface, offset IID_IBasicAudio, addr igb.piba)
or ebx, rvCoInvoke(igb.pigb, IGraphBuilder.QueryInterface, offset IID_IVideoWindow, addr igb.pigw)
or ebx, rvCoInvoke(igb.pigb, IGraphBuilder.QueryInterface, offset IID_IMediaSeeking, addr igb.pims)
.if Zero? ; if !ebx then everybody returned S_OK above
CoInvoke igb.pigb, IGraphBuilder.RenderFile, CurrentFile$, 0 ; CurrentFile$ can be a URL
Another DirectShow example with direct access to the pixeldata.

So time to test it with Windows 11 ?
Or is there some secrecy, what works in Windows 11 ?
Think you can also use ffmpeg/ffplay - Hutch had an example on that through a Shell/ CreateProcess call.

Thank very much Marinus, Jochen, Timo and JoeBr!
