• FFMPEG errors with non-English characters

  1er avril 2021, par Mingli Yang

  When I tried to use the command-line to catch a chrome window with non-English characters such as ¥, or any other 中文页面, an I/O error will occur with the message "Can't find window "¥中文页面。 - Google Chrome", aborting." When the non-English characters are replaced by English ones, the errors will disappear. Environment : Windows 10, ffmpeg version 2021-03-24

  


  This works fine :
ffmpeg -f gdigrab -i title="$ English Page - Google Chrome" -pix_fmt yuv420p grab.mp4

  


  This has errors :
ffmpeg -f gdigrab -i title="¥中文页面。 - Google Chrome" -pix_fmt yuv420p grab.mp4

  


  "Can't find window "¥中文页面。 - Google Chrome", aborting."

  


  Any ideas to solve this ?

• Make UDP-RTMP bridge with FFMPEG

  3 mai 2017, par Jorge Anzola

  I need to make this chain, using computer 2 as a "bridge" between Computer 1 and the streming server.

  Computer 1 ----> Computer 2 ----> Streaming server (Wowza).

  So I’m trying to set this :
  Computer 1 —(via UDP)—> Computer 2 —(Via RTMP)—> Wowza

  What I’ve tried :

  1. At Computer 1

  Entry :

  ffmpeg -i sample.mp4 -c:v copy -c:a copy -f mpegts udp://192.168.0.109:5010

  Result : Worked. Computer 1 sends the data correctly.

  2. At Computer 2

  Entry :

  ffmpeg -i upd://192.168.0.109:5010 output.mp4

  Result : Worked. Computer 2 gets data correctly. Output.mp4 is generated well.

  Entry :

  ffmpeg -i sample.mp4 -c:v copy -c:a copy -f flv rtmp://wowzaServerAddress

  Result : Worked. Wowza shows online the video from sample.mp4

  Entry :

  ffmpeg -re -i udp://@:5010 -f flv rtmp://wowzaServerAddress

  Result :
