  • Keywords hevc added
  • Version changed from unspecified to git-master

The stream contains 303 frames, the first 299 are decoded bit-identical with the reference decoder, the reference decoder aborts after writing 299 frames.

jctvc-hm/build/linux/lib/TLibDecoder/../../../../source/Lib/TLibCommon/TComBitStream.h:191: Void TComInputBitstream::readByte(UInt&): Assertion `m_fifo_idx < m_fifo->size()' failed.

I think that I can spot at last one artefact at the end of the video while playing the file with WMP (and installed http://xhevc.com/en/hevc/decoder/download.jsp codec), so maybe close -> invalid (bug in encoder)?
