}

What one registered video encoder declares, and what happened when alpha2 opened it.

Shows registration, advertisement and instantiation side by side, per platform.

Fields

codec: NativeVideoCodec

Logical codec this encoder implements.

encoder_name: String

FFmpeg short name.

class: NativeEncoderClass

Class taken from the encoder’s own capability bits.

hardware_accelerated: bool

Whether this row runs the encoder on the GPU.

capability_bits: u32

Raw AV_CODEC_CAP_* bits, so an unexpected class can be traced.

pixel_formats: Vec<String>

Pixel formats the encoder declares, or empty when it declares none.

hardware_configs: Vec<NativeEncoderHardwareConfig>

Hardware configurations the encoder declares.

accepts_yuv420p: bool

Whether AV_PIX_FMT_YUV420P is among the declared formats.

requires_hardware_frames: bool

Whether every declared format is a hardware one (why h264_vulkan is not advertised).

advertised: bool

Whether codec_capabilities advertises it for the YUV420P sink.

minimum_size: (u32, u32)

Smallest frame the encoder accepts, as alpha2 records it.

software_open_error: Option<String>

None when a software YUV420P frame produced a packet; otherwise why not.

software_packets: u32

Packets drained from that attempt.

rate_control: Vec<NativeRateControlProbe>

Which rate-control mechanisms opened, and with what options.
