• Revision ce08006951 : Always check and free denoiser buffer memory space The vp9_denoiser_free() func

  Always check and free denoiser buffer memory space

  The vp9_denoiser_free() function will internally check if the
  buffer pointers are NULL. This commit makes the encoder always
  call vp9_denoiser_free() after finishing encoding. It protects the
  case where noise_sensitivity_level is changed during encoding
  process and happen to be turned off towards the end of sequence,
  which could result memory space allocated to denoiser not being
  released.

• Processing3 get "Error=2 No such file or directory" with a file that actually doesn't exist at the first place

  29 octobre 2016, par Tuang Pingfavilunda

  I cannot figure it out what happen to my Processing file. I am trying to use VideoExport library and my Macbook Pro cannot play it, but the Mac-mini is able to do so.

  Before the error happened it is another error=13 permission denied thing, so I messed in the terminal for a while with chmod 777 and finding the file with ls. I don’t know if that may be the reason that caused this happen. FYI, I also installed ffmpeg already.

  And this is the full error :

      java.io.IOException: Cannot run program "/Users/Tuang/Desktop/DMA_WORKS/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde": error=2, No such file or directory

  1) The java.io.IOException : trying to call "/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde" which doesn’t exist for real. It is gone for a long time but seems like the program stuck here.

  2) "basic" is a file name from the Example of the Library. I just use it to test. Surprisingly, Every files that have been saved and changed the name still get the java.io.IOException’s error of the missing sketch_161027a.pde file.

  What I have done :
  1 I have already done the Homebrew thing to install ffmpeg.
  2 I deleted everything of Processing and reinstall it again.

  Any suggestion ?

• Setting up a server to redistribute a webcam stream

  22 janvier 2013, par Martin Taleski

  I am trying to set up a streaming server that will receive a RTP stream and redistribute it.

  I am able to create the stream with :

  ffmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp://myserver:8090/

  I see the UDP packets coming to my server, but I was not able to set up a feed and a stream with ffserver. I can also view the stream though VLC if I change the destination IP of the server with my local IP.

  I am now considering writing a daemon in python or perl or C, that will read the UDP packets coming on port 8090 on the server, and distribute them on another port. Not sure if this is a great idea, but can not find any other clues...

  Any clues how to make this happen ?
