How work command option --bluray ?

[Augusto7743]

Hello Rigaya. Thanks for reading my topic.
Obviously the command option --bluray will make an output file compatible with bluray player, but how work that command ?
Using a high number of b frames and b frame pyramid break compatibility with bluray players.
The command option --bluray disable some command options to avoid problems with bluray players ? If yes which command options are disabled ?
I wish a nice week with much peace in your life.

The --bluray option automatically adjusts encoding parameters to produce Blu-ray compliant H.264 output.

1. Validation:

• Codec must be H.264 (other codecs are rejected)
• Rate control must be VBR
• GPU must support custom VBV buffer size

2. Parameter enforcement:

• Tune H.264 bitstream structs
• Sets slice mode
• Caps H.264 level to 4.1
• Caps max bitrate to 40 Mbps, and adjusts VBV buffer accordingly
• Limits B-frames to 3 max
• Limits GOP length to 30 frames (or 60 for 720p60+)
