• avcodec/h264 : Seperate SEI and IDR recovery handling

  avcodec/h264 : Seperate SEI and IDR recovery handling
  This avoids SEI and IDR recovery flags affecting each other
  Also eliminate litteral numbers from recovery handling
  
  This should make the code clearer

  J’ai commité une version adaptée de pclzip.php du spip_loader. Il faudra up sur le serveur spip.net je pense.

• How can I record a rectangle centered around the mouse cursor when it last moved

  28 décembre 2022, par Vesoripi

  I would like an ffmpeg incantation that will do A, or B, or C where

  


  A is…
The ffmpeg incantation will record a rectangle that is centered around the caret (the "text cursor") when text is being typed.

  


  B is…
The ffmpeg incantation will record a rectangle that is centered around the mouse cursor when the mouse cursor is actually moving or when the mouse cursor had been moving less than, say, 2 seconds ago.

  


  C is…
The ffmpeg incantation will stop recording video, yet continue to record audio, if the mouse cursor had not been moving for 2 seconds or longer and the caret (the "text cursor") had not been moving for 2 seconds or longer.

  


  On Linux Mint 21.1 Cinnamon, although both of the following incantations…

  


  ffmpeg -f x11grab -follow_mouse centered -framerate 25 -video_size cif -i :0.0 -preset slow output.mkv


  


  and

  


  ffmpeg -f x11grab -follow_mouse centered -show_region 1 -framerate 25 -video_size cif -i :0.0 -c:v libx264 -crf 0 -preset slow output.mp4


  


  successfully record the mouse cursor as I would like, obviously both incantations fail to record the caret (the "text cursor") when text is being typed.

  


  Here’s my use case…

  


  As a form of documentation, I intend to create screencasts of my coding sessions which I will narrate. I realize that this unusual form of documentation would normally result in large video files. Therefore, instead of recording the entire screen, I would like to record a small rectangle around either the area where I am typing text or—when I am using my mouse—around the area my mouse cursor is located. As a result I hope to create video files which take up less storage space, yet are still useful to me.

  


  For example, I hope that when I review my coding sessions I will be able to quickly be reminded that, for example, "Oh, yeah, that's what I was thinking when I wrote that line of code. Yes. Now I remember : I was stuck, then went to Stackoverflow, did some research, and found solution XYZ to solve my problem.”

  


  In other words, I won’t exclusively be coding during my coding sessions ; sometimes I will be doing research on, for example, Stackoverflow. When I am doing research on—for example, Stackoverflow—I want my mouse cursor recorded.
