Hi to all,
I've recently started experimenting with ffmpeg to use it in order to
encode 3D objects (for a scientific purpose rather than stereoscopic
vision before anyone asks). Based on my missing knowledge in video
encoding/decoding, I used the ffmpeg example and modified it
decoding_encoding.c so that I can create a 3D 8bit object and then
encode it with HEVC and re-read it back to produce *.pgm files.
However the decoding step produces just 2 images, which is clearly not
what I was expecting given than I encoded 25 frames. I am also getting
error messages like
[hevc @ 0xe58760] Invalid NAL unit 0, skipping.
During the decoding. Does anyone have an idea what I did wrong?
I upload the source code here:

Running ffprobe on the produced *.h265 file yields:

Any help would be appreciated!
