gstreamer : Internal data error, in appsink "pull-sample" mode
9 mai 2018, par Amir RazaI am getting Internal data error, in appsink .
My application is to read .yuv data , encode and write to a buffer.I have accomplished the writing it file but when i changed the code to write it buffer it giving error.
Its only able to write only single packet (188bytes).Output of program :
(ConsoleApplication6.exe:14432): GStreamer-WARNING **: Failed to load plugin 'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\libgstopenh264.dll': 'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\libgstopenh264.dll': The specified procedure could not be found.

Now playing: Transformers1080p.yuv
