  Hello.
  I always get a "segmentation fault" warning when trying to run the command "./f265 -c f265_encode.cfg" and no data is generated from my .yuv.

  Anyone knows what could be the reason to that issue?
  I am using sudo and all the files have the necessary permissions.

  Thanks.

  Re: 2017.1.13 IC Caffe线下研讨会PPT文档

  Hello, i'm a undergraduate student from Federal University of Rio Grande do Sul (UFGRS) -Brazil - and have a big interest in studying your open- source H.265/HEVC Encoder IP Core. However, it's quite difficult for me to undestand some technicall aspects of your research due to the language barrier.

  Me and the non-chinese speaking video-coding scientific community would be very grateful if some materials could be provided in English. Such materials as the pdf presentations contained in this post or any other of them..

  I Would be very gratefull, as well, if someone could indicate all the existing documentation and tutorial material about this open source project.

  Thanks for the amazing work!
