Looks like tkvideo is not running on Win 10 64bit (error below)
Does this mean, I must compile myself?
Is there another source for the compiled version other than http://patthoyts.tk/tkvideo/?
Is there another package that can play video inside a Tcl/Tk widget?

Thanks
Alexandru

Alexandru,

I have never heared that a DLL does not run on Win10, while running on
Win8. I suppose, the error is really what is shown: 32/64 bit mismatch
of the tcl interpreter and the DLL.
There might also an issue, that it is compiled with unix-like tools, but
the extension ".dll" does not suggest this.

Howdy Alexandru,

guess you're searching for video playback only.

This might do the job: https://github.com/ray2501/tkvlc

And this would be interesting, too: https://github.com/ray2501/tcl-opencv
it you manage to build it on Windows.

BR,
Christian

Thanks for the tip.
I couldn't find any precompiled package of tkvlc.
Compiling seems to require the libVLC SDk, which I also couldn't find.
At least not in 10 min of internet search.
Any hidden links?

A fossil clone of www.androwish.org has the tkvlc source in the .../undroid/tkvlc directory.
It contains a compat directory with required VLC headers and builds tkvlc to runtime link VLC libraries which you need to install separately.

Good luck,
Christian

PS: alternatively, extract the matching tkvlc.dll from a vanillawish binary of 2019 using 7z. In any case, you need a separate VLC install for this extension.

I guess, the need for a VLC install is the party braker for me.
So currently there is no precompiled, stand alone package that can play videos for TCL, right?

Maybe you could ship an mplayer or ffmpeg binary? They are comparatively
small / standalone. Under Linux, there is an option to make mplayer
render into a Tk container frame (option -wid), however I fear that this
does not work on Windows.

So the idea with ffmpeg would be to extract the single frames from the video and than display them in a cycle inside a tk widget?

That could work, but only for rather small videos, due to the overhead
of transferring the data to disk, then Tk, then to the screen...

The idea was rather to tell ffmpeg to play the video (ffplay) to the
screen. Then you just need a way to reposition or reparent the playback
window. Maybe TWAPI can do that or ffmpeg hsa some kind of slave mode.

Speaking of performance:
The process in my case is:
1. Download the video using http::get
2. Play the video in a separate ttk::frame or toplevel together with other widgets such as pictures and text.

Other way to see it: I need tooltips that can show web content.
The idea of using an html parser/renderer also came to my mind (http://tkhtml.tcl.tk/index.html). But since I only need simple tooltips consisting of few images, text and videos, a direct implementation would be more light than a full blown html rederer..

While I don't really understand what the tooltip is for, there is a
version on the wiki with a widget for playing a video from the web:

https://wiki.tcl-lang.org/page/SnitMPlayer

According to the message by Rickster downthread, that should work on
Windows, too.

You will need to replace the youtube-dl thing with http::get according
to your needs.

Or even not: MPlayer can also play a video directly from an HTTP server,
so if you tell it to open something like
http://myserver.de/path/tovideo.mp4 on your own server then it will play
the video instantly, i.e. stream it from the URL.

Hm, I tried your code, but not much is happening. I see a yellow frame but not the video. mplayer is downloaded, I even changed relative paths in your code to full paths. Is there some key I should press to start the playback?

So I can start mplayer with an URL. I can even specify window size and position on the screen.
Theoretically that should be enough to play videos from Tcl/Tk.

There is only on thing that bothers me: the video is played in a new window that shows the typical Windows Close/Full/Minimize buttons on the top left corner.

Is there a way to integrate mplayer directly into a Tcl/Tk frame? The -wid option does not seems to work with Tcl/Tk.
