Expand description

Customization of h264 encoder parameters for macroblock quantization. The values can range from 0 to 51, with lower numbers indicating higher quality/bitrate. While encoders should support these fields if feasible, some encoders may ignore these fields. It’s ok to not set this table, or not set some of the fields in this table, as encoders can determine their own defaults. If the targeted bitrate can’t be achieved with the specified values, then the user should expect the resulting encoded stream bitrate to differ from the requested bitrate.
