• Change the rc-lookahead value for the nvenc-hevc video mode in transcode-video.rb from 32 to 20 per current Nvidia guidelines. A value of 32 is the maximum allowed but it's probably unnecessary.
• Add ratecontrol code for the nvenc-av1 video mode which functionally matches that of nvenc-hevc mode.
• Change the nvenc-av1 video mode quality value from 35 to 37. This will lower output bitrates below that of nvenc-hevc mode, a sensible move because AV1 format is supposed to be more size-efficient than HEVC at the same perceived level of quality.

• Fix the bogus VBV being set when using a custom encoder with transcode-video.rb. This bug was introduced by the previous change.

• Add missing ratecontrol code for the nvenc-hevc video mode that was stupidly left out of the original rewrite of transcode-video.rb. This also implements the --no-bframe-refs option.

• Add nvenc-av1 video mode to transcode-video.rb.

Friday, January 10, 2025

• Fix bug preventing encopts arguments being passed to the --extra option of transcode-video.rb.
• Clarify that the automatic behavior of transcode-video.rb described in the README.md file is for a single forced subtitle and does not apply to multiple subtitles.
• Add note to the README.md file regarding possible future video modes for transcode-video.rb.

• Deprecate and remove legacy RubyGems-based project files.
• Remove *.gem files from the list to ignore.
• Add redesigned and rewritten tools to the project, i.e. the transcode-video.rb, detect-crop.rb and convert-video.rb scripts.
• Completely update the README.md file.
• Begin using a date-based version numbering scheme for the project and all the scripts.

• Tag final version of legacy code no longer released as a Gem.

• Modify detect-crop to show preview commands compatible with newer versions of mpv.
• Update all copyright notices to the year 2020.

• Fix a crash in transcode-video with the --copy-audio-name option when the input audio track name does not exist. Via #279.

Saturday, March 30, 2019

• Fix a heinous multi-part bug in transcode-video which could prevent the proper detection of certain input audio formats, normally allowed for pass-through, from being copied unchanged to the output. This could also cause the --keep-ac3-stereo option from behaving correctly when used together with the --ac3-encoder eac3 option and argument. Thanks to @khaosx for finding the problem!
