Cursor movements and drawings on the screen are not included in the video content. How do I get it to record? -Google translate

C0D3D3V commented 1 year ago

Try to use the option --add-annotations like: bbb-dl --add-annotations URL For the cursor/pointer, the code is still in the project, but I removed the option to activate it, because it uses way to much computational power. If you would use it, you would not get happy with it. Maybe someone will someday optimize it a lot, but for now it is not good, because we have to render every frame new, only to add a little cursor, that takes much longer then only to add annotations.

I'm glad you're so involved. It fulfilled a serious need for me. When I tried to use the feature you mentioned as -aa, it didn't work. It's working now. I'll look into it when it's done. It doesn't matter if it takes hours, if it won't take days, how can I turn this feature on? -translate

Can you send me the URL of your bbb session? So that I can debug the code...

If it is not for public you can send it e.g. via mail (on my profile page).

Qbreak commented 1 year ago

I sent an e-mail

C0D3D3V commented 1 year ago

If you still get this error, then run the same command but add the --verbose option, then open a new issue and send the error log including some previous lines. Or just send it by mail...

C0D3D3V commented 1 year ago

Also maybe update ffmpeg xD Not sure what version you have installed, since you did not post the verbose log.

C0D3D3V commented 1 year ago

Just in case if you try to download the session again, please make sure the downloaded files are not broken (or just remove them first and then try to run bbb-dl again).
