MediaInfo

[P.curtis]

Hi All,
does anyone have any exprience with MediaInfo.dll?

I wanth to get somespecific info about a video file, for example width, height, bitrate ...

I have managed to get the demo sample program working, but I'm stuck getting specific information.

I think I need to look at the following :

Code: Pascal  [Select][+][-]

1.  To_Display := To_Display + CR + CR + 'Get with Stream:=General and Parameter=^FileSize^' + CR;
2.  To_Display := To_Display + MediaInfo_Get(Handle, Stream_General, 0, 'FileSize', Info_Text, Info_Name);

Any suggestions?

Thanks.

No experience with MediaInfo.dll.

I use ffprobe.exe, call it with TProcess and parse the output looking for what I need.   Simple text manipulation :-)  If you like I can share code...

And I use 'FFInfo4Laz':
https://forum.lazarus.freepascal.org/index.php/topic,22038.msg208700.html#msg208700,
which is Part of 'FFPlay4Laz':
https://forum.lazarus.freepascal.org/index.php/topic,26666.msg337046.html#msg337046.

... use ffprobe.exe, call it with TProcess ...

For how to read out the Output of 'FFProbe' via TProcess, You may also take a Look at 'RunFFmpeg', which is Part of 'FFGrab4Laz':
http://forum.lazarus.freepascal.org/index.php/topic,43411.0.html
-> GoTo "RunFFmpeg".

'RunFFmpeg' has Code to run the following FFmpeg-Executables:
- 'ffprobe.exe' to read out MediaStream-Data (that's what You want)
- 'ffmpeg.exe' to record/convert/manipulate Audio/Video
- 'ffplay.exe' to play them,
and read their Outputs.

For MediaInfo I would really prefer use the CLI version as a process and handle the results in my program.
