Decoding an elementary HEVC stream using ffmpeg

I have successfully compiled and installed FFMPEG_2.1 from source code. I know that ffmpeg from version 2.1 onwards supports HEVC decoder. I have generated a .bin file using HM 10.0 and HM 11.0 HEVC reference code.

However, when i give this bin file as an input to the ffmpeg i get an Input/output Error.

The command that i have used is given below:

ffmpeg -i Johnny_1280x720_60qp22.bin out.yuv

The output of the above command is as shown below:

This is the output I get for a hevc sequence encoded using HM 12.1.

Notice that in my example I get

Stream #0:0: Video: hevc, yuv420p(tv)

while you get:

Stream #0:0: Video: bintext, pal8,

HM10 is old and the NAL-structure among other things changed. Any reason for not using the latest?

To download the latest hevc reference code and how to compile it, see my post @ http://stackoverflow.com/a/19305907/297323
