I'm working on getting this to run on Linux. So far the basic features seem to work.

To run on Linux, you will need to:

• Install a recent-ish version of Mono. (Mono 4.x is known to do poorly with this program.)
• Install "Microsoft Sans Serif" font.
• Install various video tools. The binaries that this program can call are:
  • mkvinfo and mkvextract (part of mkvtoolnix)
  • ffmpeg (includes ffplay, required for audio preview)
  • mp3gain

Currently this is based off of v29.6 from Sourceforge, which was the latest version as of December 2016. There is a version v29.7 which seems to only include newer build of ffmpeg, but this version requires that you provide your own ffmpeg.

Prerequisites (Debian/Ubuntu):

• mono-complete (includes WinForms, libgdiplus, msbuild)
• ffmpeg
• mkvtoolnix (for mkvinfo/mkvextract)
• mp3gain
• Microsoft core fonts (for “Microsoft Sans Serif”)

Example install:

• sudo apt update
• sudo apt install mono-complete ffmpeg mkvtoolnix mp3gain ttf-mscorefonts-installer

Build with Mono (from repo root):

• msbuild subs2srs.sln /p:Configuration=MonoRelease
  • On older Mono: xbuild subs2srs.sln /p:Configuration=MonoRelease

Artifacts:

• subs2srs/bin/MonoRelease/subs2srs.exe

• mono subs2srs/bin/MonoRelease/subs2srs.exe

• You can also build a debug variant: msbuild subs2srs.sln /p:Configuration=MonoDebug
• Ensure ffmpeg, mkvinfo, mkvextract, and mp3gain are in your PATH.
  • ffplay must be available in PATH for the Preview Audio feature.
• If UI rendering looks off, verify libgdiplus is present (installed with mono-complete) and run under X11.
