video frame width and height

[Romeo]

Ciao

How can i have the video width and height of a file video ?

Example:
I have a file test.mp4 and i want to know the width and height of frames (600 x 1024,...)

Grazie

Dear Romeo,

I just asked the IA https://beta.openai.com/playground to write the function:

HB_FUNC( GETMP4VIDEODIMENSIONS )
{
   HRESULT hr = CoInitializeEx( nullptr, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE );
   if( FAILED( hr ) )
   {
      printf( "Failed to initialize COM library. Error code = %x\n", hr );
      hb_ret();
   }
 
   IMFSourceReader *pReader = nullptr;
   hr = MFCreateSourceReaderFromURL( hb_parcx( 1 ), nullptr, &pReader );
   if( FAILED( hr ) )
   {
      printf( "Failed to create source reader. Error code = %x\n", hr );
      CoUninitialize();
      hb_ret();
   }
 
   IMFMediaType *pType = nullptr;

   if( FAILED( hr ) )

      pReader->Release();
      CoUninitialize();
      hb_ret();
   }
 
   UINT32 u32Width = 0;
   UINT32 u32Height = 0;
 
   GUID subType;
   hr = pType->GetGUID( MF_MT_SUBTYPE, &subType );
   if( FAILED( hr ) )
   {
      printf( "Failed to get subtype. Error code = %x\n", hr );
      pType->Release();
      pReader->Release();
      CoUninitialize();
      hb_ret();
   }
 
   if( subType == MFVideoFormat_RGB24 )
   {
      hr = MFGetAttributeSize( pType, MF_MT_FRAME_SIZE, &u32Width, &u32Height );
      if( FAILED( hr ) )
      {

hi,

How can i have the video width and height of a file video ?

you need to "load" Video to get Size e.g. using WMP (Windows Media Player)

METHOD Getwidth() CLASS TWMP
RETURN ::oWMP:currentMedia:imageSourceWidth

METHOD Getheight() CLASS TWMP

Dear Jimmy,

many thanks!

[Romeo]

I am not "a great sw developer"...

I hoped a simple prg, almost ready

I try to do it

Grazie anyhow

[Jimmy]

hi,

what do you want to do with Video

if you want to "play" it you do not need "Size" while Video will use "given Size" to make a "Overlay" where it "play" it
but to "play" Video you need CODE which use OOP and not Function as it work with different Interface of ActiveX

so tell us hole Story what you want to do with Video File

[Romeo]

I downloaded from telegram thousands
Of video files about workout/fitness

There are many different resolution of them and some of them are not
good to show on TV/monitor

I wanna separate them by resolution....

And other works

[Jimmy]

hi,

Ok, i understand ... hm

perhaps you can use a "Converter" to get
a.) Information about Source Video
b.) "upscale" to new TV-Format
look at "Handbrake" which use much CPU Power

---

when you have so much Video what do you use as "Player" and how does it connect to TV (Input)

i do use WMP or VLC ActiveX in my App to "play" Video Files
a.) via HDMI of Grafic Card
b.) as "Media"-Server (http in local Network)

both "Player" also can use Internet-Stream (IP-TV) as Source

VLC also have "Record"*** Button and can "convert" Video so you can "save" Internet-Stream on local Drive
***not available in ActiveX

Tip : when Website "detect" a Smartphone it will show Video in other Format as PC which will better "fit" to TV (16:9)

[Romeo]

Grazie for info

I simply copy all the video files onto a USB key and insert it into the back of the TV, then run it from the TV remote

It is for a client who has a bodybuilding gym

[Jimmy]

hi,

open Windows Explorer and navigate into Folder where your Video Files are
right-click at End on Header to open Popup-Menu for Property

now search for "Size" and "bitrate" Property an SET Checkbox


p.s. will not show Property of every Video Type like FLV

[Jimmy]

hi,

for Programmer : File Metadata
https://github.com/Dijji/FileMeta

there is NO *.EXE so App must be build using MSVC
have to figure out how CODE can be used with harbour ...

[Romeo]
