• Revision f62805fae0 : Make local functions in vp9_dct.c static This commit limits the scope of 1-D DC

  21 juillet 2015, par Jingning Han

  Make local functions in vp9_dct.c static

  This commit limits the scope of 1-D DCT and ADST functions within
  vp9_dct.c and makes them static. This largely clears out the cross
  referencing issue between vp9_dct.c and the SIMD optimizations.

• Running Live streaming of local user using ffmpeg at Web plateform

  23 décembre 2019, par Sneha Makwana

  I am using below command to stream my live desktop screen.

  ffmpeg -f x11grab -r 1 -loglevel panic -s `xdpyinfo | grep 'dimensions:'|awk '{print $2}'` -i $DISPLAY -qscale 0 -f mpegts udp://192.168.3.151:1111

  udp ://192.168.3.151:1111 - this is my streaming URL

  I can see live streaming in the parole media player (in Linux platform), but I can’t see this in a cross-network (i.e from windows PC - in the same network)

  Is there any web platform so I can see my streaming from anywhere (either windows or linux) just using unique streaming URL or do I need to change my streaming command or method ?

  Any help is much appreciated

• Im failing to build .so file for android from FFMPEG

  15 juillet 2020, par yejafot

  I tried many times with different versions of ffmpeg but failed eventually. I dont know how they wrote .sh file to configure different tools. Here are some .sh files i tried and it all failed. Either it shows only android/share folder instead of

  


  


  • android/include

    


  


  • android/lib

    


  


  • android/share

    


  


  


  OR

  


  i end up in error like no file or folder exist,etc

  I'm using

  


  


  • ffmpeg-snapshot.tar.bz2

    


  


  • android-ndk-r21d-linux-x86_64

    


  


  


  the only thing i know in 'ndk 21` is we need to use default toolchain (android documentation says).

  


  How to create .sh file to build .so file to use in android ?
