• Gstreamer queries NVR startTime wrong

  6 septembre 2022, par james.kolinto

  I'm a newbie in gstreamer and I am trying to query a NVR(Network Video Recorder) to get recorded videos of my security camera. Here is my gst pipeline :

  


  


  gst-launch-1.0 rtspsrc location="rtsp :// :/ ?uuid=&startTime=20220823170000000&endTime=20220824080200000"
 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink

  


  


  startTime is in the format of : Year-Month-Day-Hour(2 digits)-Minute(2 digits)-Seconds(5 digits)

  


  Here, gstreamer queries the NVR for startTime and endTime, the thing is somehow it queries startTime+startTime like if I want to get 3:00 am at night I get 6 am at night.

  


  Plus there is a detail that may have importance, due to the config of my NVR I get videos recorded in startTime + 3, reason is my machine's and NVR's timezone is different. So actually I get startTime + startTime + 3...

  


  The same url works well with VLC and ffmpeg -ffplay...

  


  Thank you for reading, I appreciate any comments

  


• setting up ffmpeg on xampp server

  22 mai 2020, par altruios

  okay, I've scoured. and the best I have found are 7 year old videos with outdated information:changes in file structure on the ffmpeg(no php files) and further reading as not enlightened me on how to get this working.
the goal :
to run a shell_exec script that uses ffmpeg to convert images in a server folder into a movie.
however (since I don't know how to get the server to 'see' ffmpeg, it never runs from a php script.
shell_exec works (calculator opens up, and I can open a single image off of the server - so I know the path is correct)

  



  but In general - since there's almost no documentation that I can find on how to install on a server :(point me in the right direction)
does anyone know how to do this.

  



  C:/xampp/htdocs/gameOfLife/images/ffmpeg -r 19 -f image2  -i image_%d.png output_t3.mov


  



  is the command that works in the console but on through a php script.

  



  so how do you get an xampp server (myphpadmin set up), to run ffmpeg (or have access to it... or be able use it through php by any means) ?

  


• configure : fix compilation with glslang 14

  31 janvier 2024, par Lynne

  configure : fix compilation with glslang 14
  The configure check already had fallback for the previous version
  
  of glslang, which had different requirements for flags.
  
  This commit simply moves the flags needed for glslang 13 to the
  
  fallback, while first trying to use new flags for glslang 14.
  This drops support for 3 year old glslang versions, which
  
  I'm not sure had the complete C API we're using anyway.
