This applies software tonemapx filter for dolby vision videos that have no compatability fallback.
Due to the complexity of the reshaping process, this is quite CPU-intensive. For real-time transcoding and tonemapping of 4K 60fps content, a CPU with 16 cores of Zen3-level performance is recommended.

Some options that are too performance-intensive are disabled, while
others are left enabled to trade-off between real-time playback and quality.

LAME's VBR mode only has advantage over a certain bitrate range. For very low and very high bitrate, use the ABR mode instead.
aac_at's CVBR mode produces very good quality and is not worse than its TVBR mode in blind testing. Use this mode for convenience.
The ffmpeg native aac encoder will have quality regression with its VBR mode. Always use CBR mode for ffmpeg's native aac encoder.

This would be significantly faster than decoding every frame, but it does have compatibility issues. Not all decoders support this mode, notably the VP9 decoder, CUVID decoders, and QSV decoders.
Some videos with very long key-frame intervals may also perform poorly with this mode, as the image timing could become too inaccurate to reflect the actual frame.

* Force video size as thumbnail size if the trickplay width setting is larger
This will fix an issue when the trickplay setting contains a very huge width, but the video has a lower resolution than that setting. Our scaling filter logic will not do any upscale, and we have to force to use the video width
