UDF made by Frank10 with changes made to SaveFile() by mLipok (Recording working)

Can you stick with separate UDF files instead merging them ?

I mean: WebcamDS_UDF.au3 + DirectShow_Interfaces.au3 + WebcamDS_ExampleUDF.au3

How old is your computer ?
Which codec you choose ?

The computer I tested is about 5 years old.
the codec I used was "Xvid MPEG-4" which creates smaller files.

I put everything together in a script, just the UDF made by Frank10 and the other one that you changed to make it easier to compare and thus try to remove the errors that occurred in the UDF that you changed.

It is very good UDF,I'm reference it modify to full function program.

5 stars UDF

Hi

How to add ffmpeg to Codecs ? 

How to use x264vfw for create mp4 file?

how to setup audio for codecs ? 

How to save to x264 mp4 format ?

 

audio not synced in certain of codecs (example : x264vfw - H.264/MPEG-4 AVC codec)

Ans :
[1]Register COM
(1)regsvr32 -s C:\ffdshow.dll
or
(2)Dllcall   ffdshow.dll  DllRegisterServer function

[2]AddFilter
Example like :
 $Custom_PushSource_Desktop_Filter = ObjCreateInterface($CLSID_PushSource_Desktop_Filter, $IID_IBaseFilter, $tagIBaseFilter)
 $hr = $oGraph.AddFilter($Custom_PushSource_Desktop_Filter, "Custom_PushSource_Desktop_Filter")

[3]Setting and writte file
pBuild->SetOutputFileName( $MEDIASUBTYPE_Avi, "C:\Recording.avi", $pMux,  $pSink  )


[4]Connect & Render
Find pin and connect
[Capture filter] ----> [Encode filter (H.264/AAC)] ----> [Write filter (Mux/Writer)]

[5] Setting Video to GUI
$oVideoWindow.put_Owner($hGUI)
