Enum VideoCodec

}

Which software encoder to open. Whatever’s picked, SwEncoder::new fails with SwEncoderError::CodecNotFound (not a panic) if the linked ffmpeg build doesn’t actually have it — this crate never vendors any of these, it’s whatever the local ffmpeg install was built with (check with ffmpeg -encoders).

GPL-licensed encoders need an ffmpeg build compiled with --enable-gpl (separate from — and unlike — FFmpeg’s own native h264/hevc decoders, which SwDecoder already uses and which carry no such requirement; GPL only enters the picture on the encode side, through these specific libraries): VideoCodec::H264 and VideoCodec::H265 are GPL. Every other variant here is a permissively-licensed (BSD/similar) alternative that needs no special build flag beyond being enabled at all. libx264 — H.264. GPL.

Variants

H264

OpenH264

libopenh264 — H.264, Cisco’s BSD-2-Clause encoder (Cisco covers H.264 patent royalties for binary redistributions of it). The non-GPL alternative to VideoCodec::H264.

H265

libx265 — H.265/HEVC. GPL.

Kvazaar

libkvazaar — H.265/HEVC, BSD-2-Clause. The non-GPL alternative to VideoCodec::H265.

Vp8

libvpx — VP8, BSD-3-Clause.

Vp9

libvpx-vp9 — VP9, BSD-3-Clause (same libvpx project as VideoCodec::Vp8, different encoder name).

Av1

libaom-av1 — AV1’s reference encoder, BSD-2-Clause. Most broadly compatible AV1 output, but much slower than VideoCodec::Svtav1 — prefer that one unless you specifically need libaom’s own encoding behavior.

Svtav1

libsvtav1 — AV1 via Intel’s SVT-AV1, BSD-2-Clause-Patent. Far faster than VideoCodec::Av1 (libaom-av1) at a given quality target — the practical default for real-time AV1 encoding.
