• Python threading module on windows after session logout

  1er décembre 2013, par e271p314

  I wrote a code which starts to record screen capture from the second it identifies mouse movement until it identifies the mouse didn't move for a predefined time (10 seconds).
  In python, on windows, how to wait until mouse moves ?
  If, I'm logged in to the session the code works fine, i.e. it starts and stops on time and records the screen capture. But, if I logout, I expect the script to identify that the mouse doesn't move and stop recording. Instead, the code doesn't stop and when I login again (long after the 10 seconds passed), the screen capture (from the previous session) keeps running, yelling the rt buffer is full and it keeps running until I close the cmd console even I expect it to work for 10 seconds (at least when I'm logged in). Any idea what is the issue ? I feel like it is something between the threading module and the session logout but I could be completely wrong about this.

• Screen recording and live streaming (Windows DXGI) - C++

  16 mai 2020, par NewbieCoder

  I am using the Desktop Duplication API in Windows to obtain images of the screen. I know to obtain the bitmap image of the screen by using the API but I am stuck after this. To stream it to the server I thought of encoding it into H264 and then encoding that again to RTMP and then streaming it to the server. Is there a better and faster way ?

  



  I searched many times and most of the answers are using FFmpeg and just finishing the whole task of screen recording to streaming in a single line. Please tell me a way to do this programmatically !!

  



  How do I encode to H264 and then to RTMP ? If the video is being double encoded, will this result in a loss of performance in both streaming side and receiving side ?

  



  Please point me in the right direction. Any hints or links will be very helpful.
