videoconverter

Installation

The recommended installation method is with nix. This repository is a flake, and a default.nix is provided for flexibility.

Alternatively, cargo install should work provided you have ffmpeg installed in a way that pkg-config can see.

Usage

videoconverter [path].

[path] is optional, and defaults to .

Run videoconverter -h to see all possible arguments and their defaults.

If TV show mode is enabled, the program will ask for the following:

• The show name
• The current season
• The first episode in the current directory. (This one is useful for when you've got a season of a show split amongst multiple directories, i.e. a DVD box set)

The program will attempt to read the previous values of these from a statefile (by default /tmp/videoconverter.state). If this is present it will suggest these to you as default values.

Output

The program will analyse each file, and convert audio and video streams appropriately, to the following:

• Container:
  • .mkv
• Video:
  • If the original stream is h.264 or h.265, it will be copied.
  • If GPU mode is enabled (--gpu), the stream will be encoded as h.265 (nvenc) with the following flags: -rc constqp -qp 20 -preset slow -profile:v main -b:v 0 -rc-lookahead 32.
  • Else, it will be encoded as h.264 (libx264) with the following flags: -profile:v high -rc-lookahead 250 -preset slow -crf 20 -x264opts opencl.
• Audio:
  • If the original stream is aac or flac, it will be copied.
  • If the original stream is DTS-MA or Dolby TrueHD, it will be encoded as flac.
  • Else, it will be encoded as aac (libfdk_aac) with the following flags: -cutoff 18000 -vbr 5.
• Subtitles
  • If the original stream is HDMV_PGS (Bluray) or DVD, it will be copied.
  • Else, it will be encoded as ssa (ass).

If there are English audio and subtitle streams, then other languages' streams will be discarded. This can be overridden with --all-streams.

If the file contains more than one video stream, only the first will be kept. If it contains zero video streams, the program will panic.
