get_conf()

static int get_conf ( AVCodecContext * avctx, oapve_cdesc_t * cdsc )

static

Populate the liboapv configuration from AVCodecContext and encoder options.

AVCodecContext fields are applied first, followed by liboapv private options and finally oapv-params. The APV profile defaults to the minimum profile implied by pix_fmt, and later overrides must remain compatible with that pixel format.

Parameters

[in]	avctx	codec context (AVCodecContext)
[out]	cdsc	contains all APV encoder encoder parameters that should be initialized before the encoder is use

Returns

0 on success, negative error code on failure

liboapve_init()

static av_cold int liboapve_init ( AVCodecContext * avctx )

static

Initialize APV codec Create an encoder instance and allocate all the needed resources.

Parameters

avctx

codec context

Returns

0 on success, negative error code on failure

Definition at line 476 of file liboapvenc.c.

liboapve_encode()

static int liboapve_encode ( AVCodecContext * avctx, AVPacket * avpkt, const AVFrame * frame, int * got_packet )

static

Encode raw data frame into APV packet.

Parameters

[in]	avctx	codec context
[out]	avpkt	output AVPacket containing encoded data
[in]	frame	AVFrame containing the raw data to be encoded
[out]	got_packet	encoder sets to 0 or 1 to indicate that a non-empty packet was returned in pkt

Returns

0 on success, negative error code on failure

Definition at line 568 of file liboapvenc.c.

liboapve_close()

static av_cold int liboapve_close ( AVCodecContext * avctx )

static

Destroy the encoder and release all the allocated resources.

Parameters

avctx

codec context

Returns

0 on success, negative error code on failure
