The h264bsd fully doesn't render the original colors about h264bsd HOT 2 CLOSED

The anomaly you're seeing is due to studio color range versus full color range. The best explanation I could find is here: https://en.wikipedia.org/wiki/YUV#Numerical_approximations

They are generally a pain to deal with in encoding/decoding loops

If you're input coolers are limited to studio range [16,235], the renderer will reproduce your colors exactly.

If you want to use full range colors, you will need to adjust the YCbCr conversion matrix here

I'll see if I can add a flag for switching between full and studio range.

I've added an optional parameter to the H264bsdCanvas 'fullRangeColor' that will assume that the input is full range color.

That should remove the clipping you're seeing.
