MYTHFFMPEG(1)

✨ NAME ✨

mythffmpeg — the MythTV FFMpeg helper 💖 (yes bestie, it's the ffmpeg that ships with MythTV, and it does exactly what you think it does)

---

🎀 DESCRIPTION 🎀

Okay so first things first, here's the identity card it prints, no cap:

ffmpeg version 8.0.1 Copyright (c) 2000-2025 the FFmpeg developers

and it was built with gcc 15 (Ubuntu 15.3.0-2ubuntu1), configuration and all, so here's the whole receipt verbatim because we do NOT paraphrase build flags in this house 🫶:

It's a universal media converter babe, and the whole vibe is:

ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

🔍 Getting help:

• -h — print basic options
• -h long — print more options
• -h full — print all options (including all format and codec specific options, very long) 👀 seriously it's so long
• -h type=name — print all options for the named decoder/encoder/demuxer/muxer/filter/bsf/protocol

See man ffmpeg for detailed description of the options. That's the real one, this is the short version 💅

Also, lil glow-up detail: per-stream options can be followed by :<stream_spec> to apply that option to specific streams only. And <stream_spec> can be a stream index, or v/a/s for video/audio/subtitle (see manual for full syntax). Very target-your-streams of it.
