Where can I send my application papers to ?

Thank You, Fred - I'll check that Option. 

What Do You think? Isn't this a good Occasion to start a new Topic, like
"Where should I publish & share my Codes & Projects ? (which Host to choose)"
to discuss the Pros & Cons of those Sites ?

For Example, what's Your Opinion about this ?
https://www.securitynewspaper.com/2020/05/07/microsoft-is-owner-of-github-and-its-own-github-account-hacked/#:~:text=Microsoft%20is%20owner%20of%20GitHub%20and%20its%20own,data%20stored%20in%20Microsoft%E2%80%99s%20private%20repositories%20on%20GitHub.
-> GoTo "The threat actor offered...on a hacking forum...to use site ‘credits’ to gain access to the exposed data".   

Or that:
https://about.gitlab.com/terms/#gitlab_com
-> GoTo "..., you are responsible for maintaining the security of your account, and
               you are fully responsible for all activities that occur under the account and
               any other actions taken in connection with the account.". 

Having taken a quick Look at the GitHub-Site, I only see Advantages for Teams of Developers.
'FFPlay4Laz' (like 'FFInfo4Laz' and 'FFGrab4Laz' with 'RunFFmpeg') is entirely made of my own.

So, why should I complicate my Life unnecessarily ?

Yes do it (I am already converted but it is interesting).

Sorry but I am not paranoiac, honesty rules my life and all the code that I share follow that way too.
I only see the advantages that those sites give me to share my code, have push request sometime from other users, all the source in a place more safer than my only laptop that risk to die soon.

Fre;D

Maybe, I know too much lawyers.

Get a ThinkPad. Used ones are not expensive, at all.
I rescued mine, a ThinkPad T400s, from being thrown away. Got it for free, repaired it, and
it works perfectly since many Years.

Huh, I have a ThinkPad X390...

> safer than my only laptop that risk to die soon

That, for example, is not honest.
Like everybody I know that a ThinkPad never die.

(You see that the "total honesty" is not easy to reach.)

You see that the "total honesty" is not easy to reach.

I think, I should start that Topic about Code-Hosts.

Done: https://forum.lazarus.freepascal.org/index.php/topic,50973.0.html.

well, I couldn't get an image. only the green screen. I used the ffmpeg 4.0.2 and 4.1.4 headers. the result is the same everywhere.

[Guva]

Oh no .... it's my problem with nvidia drivers. It works fine under intel...

[metis]

So, You're the First, who tried 'FFPlay4Laz' on Linux. 
You should post the Reason for Your initial Problems, and how You fixed it.

[Guva]

My modify ffmpeg headers  for linux ....

Uses AMD Video Card
I haven't found a solution yet. alternatively, use graphics from Intel. The problem only occurs with Op]"]>Blockeds laptops...

[metis]

Have Fun with 'FFPlay4Laz'.
What do You need it for? I use it mostly for MusicVideos (-> Portaudio), and
to watch Tutorials, that I've downloaded with the '4K Video Downloader':

Is it possible to use this project to create screen recording software? Recording a given fragment of the screen and sound output, using hardware acceleration, saving to an mp4 file — only the basics. Something like that would be useful to me for recording my Tetris games — a small tool that works on XP, light and effective.

@furious programming

This Topic treats 'Rendering with FFmpeg-Libraries' - for Recording-Issues, see 'FFGrab4Laz':
https://forum.lazarus.freepascal.org/index.php/topic,43411.0.html.

-> GoTo: ScreenRecorder2FPC,
which is a FPC-Example for Recordings with FFmpeg-Libraries (for the Moment w/o Audio).

-> GoTo: RunFFmpeg,
which is for anything else, that 'FFmpeg' can do for You, simply by using the FFmpeg-CLIs themselves.
With the preset CommandLines, You can
record a Part of the Screen (= [Grab] -> [Stop]), and then read out Infos about the recorded File (= [Info]) and play it (= [Play]).
All done with the MKV-ContainerFormat (= Matroska, which is a free Format).

With MP4 Things are different:
Recordings must be stopped with <q> (= quit), otherwise the created VideoFile won't be valid, means not playable.
This Part is not implemented yet in 'RunFFmpeg', but You may do so in the SourceCode, which is
attached to the initial Post of 'FFGrab4Laz' (see 'FFGrab4Laz_01.7z').
Or take FFmpeg's CommandLine-Tool 'ffmpeg.exe' directly to record the Screen to MP4-Files with CommandLines, like e.g. ...

ffmpeg.exe -f gdigrab -framerate 30 -video_size 1280x768 -i desktop "grabbed.mp4"
to record the entire Screen w/o Audio.

ffmpeg.exe -f gdigrab -framerate 30 -offset_x 10 -offset_y 20 -video_size 640x480 -show_region 1 -i desktop "grabbed.mp4"
to record a Part of the Screen w/o Audio.

ffmpeg.exe -f gdigrab -framerate 30 -video_size 1920x1080 -i desktop -f dshow -i audio="Sound Blaster Audigy" -vcodec libx264 -pix_fmt yuv420p -preset ultrafast "grabbed.mp4"
to record the entire Screen with Audio, where
"Sound Blaster Audigy" is the Name of my AudioDevice, and may be different on Your System.

Note: 'gdigrab' and 'dshow' is for Windows, only (I use WinXP, too).

By Modifying the CommandLine-Arguments, You can record the Screen with any Framerate, AV-Quality, Format, etc., which
is supported by 'FFmpeg', and this is a lot.
