[FFmpeg-user] ffmpeg x265 profile Main10

[Osztrovszky Zsolt]

Hello Guys,
I’d like to create an h265 video with Main10 profile (10 bits).
However ffmpeg keeps saying that profile=main10 is an unknown option.
My command:
ffmpeg -i vid.ts -c:v libx265 -preset medium -x265-params “profile=main10:crf=30” -c:a aac strict experimental -b:a 128k output.mp4

please help me

cheers,
Zsolt

ISTR that x265 profiles are not yet supported, however you can still
make a MAIN10 file by setting other parameters. for example:-

-c:v libx265 -pix_fmt yuv420p10le \
-preset fast \
-x265-params level=5.2:vbv-bufsize=60000:vbv-maxrate=60000:crf=20

Prodcued some thing that when probed shows:-

Stream #0:0(und): Video: hevc (Main 10) (hev1 / 0x31766568),
yuv420p10le(tv), 3840x2160.....

That's mentioned in this trac ticket by the way:

Just for reference: A similar thing was figured out here:

Thanks Tim, I've tried your solution, but it didn't work :(

http://pastebin.com/UyMsRPtg

As you can see in line 20, the input video is hevc Main 10, but the encoder still coding it to Main profile, 8 bit (line 27).
It also says in line 23: incompatible pixel format 'yuv420p10le' for libx265.
What am I missing here?

Cheers,
Zsolt

I think you have to compile libx265 with 10 bit support. (libx264
suffers the same restriction.) Unfortunate, but that's the way it is.

Indeed you need the cmake option "HIGH_BIT_DEPTH:BOOL=ON"

This gives you up to 16 bit support, so not quite the same as x264.

Oh I see.
Can you help me with some links, how to compile it with 10bit support?
