Modules

amf

Stub AMF encoder, compiled when the amd feature is off.

nvenc

Stub NVENC encoder, compiled when the nvidia feature is off.

qsv

Stub Intel QSV encoder, compiled when the qsv feature is off.

tuning

AV1 encoder tuning adapter.

Structs

EncodedPacket

EncoderConfig

Encoder configuration.

OutputCaps

What output formats an encoder path can produce. AV1 here is 4:2:0 only; 10-bit output is the web-safe AV1 Main profile (4:2:0 10-bit), HDR-tagged at the container level (colr/mdcv/clli), not the wide-gamut professional profiles.

Functions

av1_encode_capable

Whether an AV1 encoder can actually be constructed for this device — the authoritative, build-aware capability check. It runs the same select_encoder dispatch a per-chunk worker uses, pinned to the device’s vendor + index, so true means a worker leased to this GPU will encode rather than hard-fail. Used to drop AV1-incapable cards (e.g. a pre-Ada NVIDIA that decodes via NVDEC but has no AV1 encode silicon) from the multi-GPU encode pool, so a mixed-vendor host encodes on the capable cards instead of aborting when a chunk leases to an incapable one.

backend_output_caps

Output capabilities of a specific hardware backend. All three do 10-bit AV1, so they can produce HDR without the ffmpeg feature: NVENC via Yuv420_10bit, AMF via P010, and QSV via the in-repo oneVPL P010 path ([qsv_p010]).

build_output_caps

Output capabilities of this build — the union over every compiled encoder path. 10-bit + HDR comes from NVENC (nvidia), AMF (amd), QSV (qsv, via the in-repo P010 path), or the ffmpeg software/hwaccel encoders; a build with no encoder feature is 8-bit. Callers (e.g. rivet’s OutputSpec::validate) use this to reject a format the build can’t produce.

encode_backends

AV1-encode backends compiled into this build, in dispatch-preference order.

select_encoder

Create the best available AV1 encoder.
