you're right, I had understood it was opensource but it seems not

I had understood it was opensource but it seems not

Partially it is...

The Demo-GUI is OpenSource:
https://forum.lazarus.freepascal.org/index.php/topic,26666.msg337046.html#msg337046
-> GoTo "LCL-Test&Demo-GUI (FFPlay4Laz-FrontEnd)".
This Demo-GUI shows, how to use the FFPlay4Laz-API (currently only for FFPlay4Laz v1.x).
You may take and modify it for Use with other event-driven MediaPlayer-APIs like 'VLC'.
If 'MPV' interfaces via Pipes&Strings like the 'MPlayer', it won't be that useful for You.

The FFPlay4Laz-Player's BasicStructure is also OpenSource:
- for SDL1: http://forum.lazarus.freepascal.org/index.php/topic,26666.msg196377.html#msg196377
   -> download attached 'DrangerTutorial08.c2FPC.lpr.zip'.
- for SDL2: https://forum.lazarus.freepascal.org/index.php/topic,26666.msg373185.html#msg373185
   -> download attached 'FFPlay4Laz2_MINIMALST.7z'.
This is cross-platform FPC-Code. You may compile it to Mac or Linux, too.
The fully-featured FFPlay4Laz-Player/-PlayerEngine is closed, and Win32-only for the Moment.

The FPC-Code to read out all File-/StreamData via FFmpeg-LIBs (= FFInfo4Laz) is OpenSource, too:
https://forum.lazarus.freepascal.org/index.php/topic,22038.msg208700.html#msg208700
-> download attached 'FFStreamInfo.lpr.txt'.
This is quite close to the Code, that is called when <i> is pressed in the FFPlay4Laz-Console.

From I read FFPlay4Laz2 requires .DLLs from ffmpeg.

FFPlay4Laz uses FFmpeg mainly as Demuxer&Decoder,
where the FFPlay4Laz-VersionNumber indicates the required FFmpeg-Version.

For CopyrightReasons everyone has to download the FFmpeg-Libraries by himself - Sorry. 
The next Release of FFPlay4Laz2 will use the latest WinXP32-compatible FFmpeg-Builds by Reino:
https://rwijnsma.home.xs4all.nl/files/ffmpeg/?C=M;O=D
With these FFmpeg-Builds, FFPlay4Laz2 will render additionally AOMedia's AV1-VideoCodec, whilst
it still runs from WinXP to Win10 w/o any Changes.

I changed it because MPV seems more flexible to me but in any case we can implement several engines

If You'd like full Flexibility + full FPC-PlayerSource, furthermore as a Lazarus-Component, see here.

I looked at it, but at the beginning there is this sentence:

Hi to all, who are Looking for a (Windows only) FFmpeg-based MediaPlayer-Component for Lazarus !

mpv works for me on Windows, Linux and macOS.

@Espectr0

mpv works for me on Windows, Linux and macOS.

So, You use it as a command-line interface, don't You ?
Are there Pascal-/FPC-Header for MPV ?

..., but at the beginning there is this sentence: ... (Windows only) ...

You should have read further:
This is what Somby made of it - All this Code could also be written cross-platform.

[Espectr0]

I use libmpv interface, the headers are translated from the originals.

https://github.com/URUWorks/UW_MPVPlayer

Any idea or help is welcome to improve it.

[metis]

I use libmpv interface, ...

Well, that's actually the difference:
You use an AV-PlayerEngine, whereas FFPlay4Laz is an AV-PlayerEngine:
no VLC, no MPlayer, no MPV, etc. required.
It links directly against the FFmpeg-, SDL- and PortAudio-Libraries to obtain
maximal control and make it as fast, precise and responsive as possible.

[Espectr0]

I'd love to use it when it's open source.

[metis]

There will be a Library.
Problem is ... Time, Time, Time.

I tried your UW_MPVPlayer and it works great. The only thing I am not sure how to do is handling subtitles.
Can this component display subtitles on it's own or do I have to do this myself (check current video position, display text somewhere on screen)?
If it can display subtitles- how can I display subtitles from file (.SRT) and how embedded subtitles?
If it can't display subtitles- how can I extract subtitles embedded in a video?

[Espectr0]

• "AutoLoadSubtitle", you can indicate that it loads subtitles automatically (if true, Load the media filename with subtitle file extension and possibly language suffixes).
• "LoadTrack", you specify what type of additional track to load (Video, Audio, Subtitle) and its external file.
• "SetTrack", you specify which track to activate.
• "ShowText", shows a text in the video, supports ASS Tags so you can indicate color, position, etc...

Thank you, that's great!
