• Building for macOS, but linking in object file built for free standing

  5 novembre 2020, par RPSM

  I am building ffmpeg and I get the following error for several files. I am not specifically building with the free standing flag, so cannot see why this is happening. What does it actually mean ? Is there a problem with it, or is it an ignorable warning ? If there's a problem, does anyone have any idea how to fix it ?

• Revision 73261850fe : Allow building multi-res encoder with —shared Export vpx_codec_enc_init_multi_

  16 décembre 2014, par Johann

  Changed Paths :
   Modify /vpx/exports_enc

  
  
  Allow building multi-res encoder with —shared

  Export vpx_codec_enc_init_multi_ver so the vp8 multi res encoder example
  can see it when building shared.

• Gstreamer basic tutorial gives blank screen

  11 novembre 2013, par user763410

  I have the following gstreamer basic tutorial. When I compile and run the program, I am only getting a blank screen. The same happens when I use mplayer, but I supply -vo x11 option to it and it works well(for mplayer). So, I am guessing the issue gstreamer is also the same. So, my question is..."What should I do to tell the program that my output driver is x11 ?" How do I get rid of the blank screen ?

  Thanks
