Name of the codec implementation.

The name is globally unique among encoders and among decoders (but an encoder and a decoder can share the same name). This is the primary way to find a codec from the user perspective.

Descriptive name for the codec, meant to be more human readable than name.

You should use the NULL_IF_CONFIG_SMALL() macro to define it.

Copy necessary context variables from a previous thread context to the current one.

If not defined, the next thread will start automatically; otherwise, the codec must call ff_thread_finish_setup().

dst and src will (rarely) point to the same context, in which case memcpy should be skipped.

Encode data to an AVPacket.

Parameters

avctx codec context

avpkt output AVPacket (may contain a user-provided buffer)

[in] frame AVFrame containing the raw data to be encoded

[out] got_packet_ptr encoder sets to 0 or 1 to indicate that a non-empty packet was returned in avpkt.

Returns

0 on success, negative error code on failure
