• Ffmpeg ./configure not found

  8 juin 2016, par Justin Tullock

  I’m trying to install ffmpeg with libvpx & libx264 on my vps. Centos07. I’ve followed these instructions https://trac.ffmpeg.org/wiki/CompilationGuide/Centos to the T.

  Now when I try to run

  cd ~/ffmpeg; ./configure --enable-libvpx --enable-gpl --enable-libx264

  it returns

  -bash: ./configure: No such file or directory

  When I try ffmpeg -v

  ffmpeg: error while loading shared libraries: libx264.so.148: cannot open shared object file: No such file or directory

  and ldd $(which ffmpeg) returns

  root@host [~/ffmpeg_sources]# ldd $(which ffmpeg)

  I’ve followed all the instructions exactly - is there something I’m missing ?

• Revision 0002da32e6 : arm : Fix building vp8_subpixelvariance_neon.c with MSVC Use the right return va

  4 septembre 2014, par Martin Storsjo

  Changed Paths :
   Modify /vp8/common/arm/neon/vp8_subpixelvariance_neon.c

  
  
  arm : Fix building vp8_subpixelvariance_neon.c with MSVC

  Use the right return values - vget_low_s64 returns int64x1_t, not
  a normal int64_t.

  Also make __builtin_prefetch a no-op on MSVC for this file.

• FFMPEG reporting EOF for network connection every so often, why ?

  23 juillet 2015, par Alex

  I have the code as follows

      av_open_input_file("rtsp://.....);
  
      while(av_read_packet() >= 0) {
  
        // do something with the packet
  
      }

  The problem is I am only able to receive, say, 100-200 packets and then av_read_packet returns EOF error. So I have to reconnect and start getting frames again.

  I wonder if I can set some options to av_open_input_file() (or maybe use some other API) so that the connection wouldn’t drop that often.

  Thank you
