x265 HEVC Encoder

[tormento]

I have tried Patman’s build and SCC seems to be encoding but the result is an error about premature end of file and a black unreadable video. He confirmed the issue.

Someone had better luck?

Yes, a freshly built x265 v3.6+130 with SCC enabled encodes but MPC-HC with its internal LAV filters can't decode it properly. That's probably due the libavcodec HEVC decoder to not supporting HEVC SCC Profile bitcode. You would need to find another decoder which is able.

SCC is one those things related to streaming, like webinars with PowerPoint presentations etc. For example SVT-AV1 has had it for a long time already, but of course it's really not meant for your regular content.

Do you know a player that can actually reproduce it?

Why does StaxRip give a frame error at the end? I didn't try with other GUIs so I don't know if it's a x265 or StaxRip issue.

Moreover, when muxing the hevc, MKVToolnix-gui outputs a very short video.

Quite recent MP4Box and FFmpeg versions can multiplex it to MP4. But mkvmerge seems to recognise only HEVC packets known in basic profiles.

And the native HEVC decoder in libavcodec, core of ffmpeg, does not yet support decoding it.

No serious changes in intel x86[-64] code.

Reported to Moritz Bunkus - low priority, there is no need to hurry without a decoder yet.
