I've got a question regarding the decoding process for HEVC-coded sequences. When timing the process I found that the decoding of the first frame always takes twice as long as the decoding of all the other frames.
While I'm happy to try to reproduce your problem and ask smart questions, let me please point out:
ffmpeg version 2.1.git Copyright (c) 2000-2014 the FFmpeg developers built on Feb 20 2014 16:27:13 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)
This version of ffmpeg is extremely old, considering the amount of development happening. Especially with such a "new" codec as HEVC, you can expect many improvements over 18 months. And if ffmpeg happens/happened to have a bug, it may very well have been fixed in the meantime. Nobody here will help trying to identify a bug in such an old version. Please repeat your tests with a very recent version of ffmpeg, best is if you build if from git HEAD. Thanks, Gruß, Moritz
