does Avidemux support x264 10bit (Hi10P) already?

[tnt]

as my x264 supports 10bit encoding for a long time, there is a question does Avidemux support x264 10bit (Hi10P) already?

thx.

I wonder if Avidemux uses 8 bit depth internally? (Can't check the code ATM.) In this case 10 bit encoding would be sort of pointless, wouldn't it?

The x264 library is either 8 bit or 10 bit (specified at the compile time). Build Avidemux against the 10 bit version and it will produce 10 bit h264 videos.

(Everything very much AFAIK)

yes, internally avidemux is 8 bits
It is counterintuitive, but in some cases, 10 bits encoding has better compression ratio than 8 bits

10bits decoding is supported
HW support is  ~ working in the ffmpeg 31 branch only (windows/vaapi)
