VideoDecoder

#include <icy/av/videodecoder.h>

Inherits: VideoContext

Decodes compressed video packets into raw frames.

Public Methods

Return	Name	Description
	`VideoDecoder`	Construct a decoder for the given stream. The codec parameters are read from the stream's codecpar.
`void`	`create` `virtual`	Initialise the AVCodecContext from the stream's codec parameters.
`void`	`open` `virtual`	Open the codec and initialise any required pixel format conversion context.
`void`	`close` `virtual`	Close and free the AVCodecContext and associated resources.
`bool`	`decode` `virtual`	Decode the given compressed video packet and emit the decoded frame. Input packets must use the raw AVStream time base; time base conversion to microseconds is performed internally.
`void`	`flush` `virtual`	Flush any frames buffered inside the decoder. Call repeatedly after the last packet until false is returned.

VideoDecoder

VideoDecoder(AVStream * stream)

Construct a decoder for the given stream. The codec parameters are read from the stream's codecpar.

Parameters

stream The AVStream to decode; must remain valid for the lifetime of this decoder.

create

virtual

virtual void create()

Initialise the AVCodecContext from the stream's codec parameters.

open

virtual

virtual void open()

Open the codec and initialise any required pixel format conversion context.

close

virtual

virtual void close()

Close and free the AVCodecContext and associated resources.

decode

virtual

virtual bool decode(AVPacket & ipacket)

Decode the given compressed video packet and emit the decoded frame. Input packets must use the raw AVStream time base; time base conversion to microseconds is performed internally.

Parameters

ipacket The compressed video packet to decode.

Returns

True if an output frame was decoded and emitted, false otherwise.

flush

virtual

virtual void flush()

Flush any frames buffered inside the decoder. Call repeatedly after the last packet until false is returned.
