Member Function Documentation

◆ AddData()

bool CDVDVideoCodecFFmpeg::AddData ( const DemuxPacket & packet )

overridevirtual

add data, decoder has to consume the entire packet returns true if the packet was consumed or if resubmitting it is useless

Todo: : properly handle avpkt side_data. this works around our improper use of the side_data

Implements CDVDVideoCodec.

◆ Dispose()

◆ FilterClose()

void CDVDVideoCodecFFmpeg::FilterClose ( )

◆ FilterOpen()

◆ FilterProcess()

CDVDVideoCodec::VCReturn CDVDVideoCodecFFmpeg::FilterProcess ( AVFrame * frame )

protected

◆ GetAllowedReferences()

unsigned CDVDVideoCodecFFmpeg::GetAllowedReferences ( )

overridevirtual

Number of references to old pictures that are allowed to be retained when calling decode on the next demux packet

Reimplemented from CDVDVideoCodec.

◆ GetCodecStats()

bool CDVDVideoCodecFFmpeg::GetCodecStats	(	double &	pts,
		int &	droppedFrames,
		int &	skippedPics )

overridevirtual

For calculation of dropping requirements player asks for some information.

pts : right after decoder, used to detect gaps (dropped frames in decoder)
droppedFrames : indicates if decoder has dropped a frame -1 means that decoder has no info on this.
skippedPics : indicates if postproc has skipped a already decoded picture -1 means that decoder has no info on this.

If codec does not implement this method, pts of decoded frame at input video player is used. In case decoder does post-proc and de-interlacing there may be quite some frames queued up between exit decoder and entry player.

Reimplemented from CDVDVideoCodec.

◆ GetConvergeCount()

unsigned CDVDVideoCodecFFmpeg::GetConvergeCount ( )

overridevirtual

How many packets should player remember, so codec can recover should something cause it to flush outside of players control

Reimplemented from CDVDVideoCodec.

◆ GetFormat()

enum AVPixelFormat CDVDVideoCodecFFmpeg::GetFormat	(	struct AVCodecContext *	avctx,
		const AVPixelFormat *	fmt )

◆ GetHWAccel()

IHardwareDecoder * CDVDVideoCodecFFmpeg::GetHWAccel ( )

overridevirtual

Implements ICallbackHWAccel.

◆ GetName()

const char * CDVDVideoCodecFFmpeg::GetName ( )

inlineoverridevirtual

should return codecs name

Implements CDVDVideoCodec.

◆ GetPicture()

CDVDVideoCodec::VCReturn CDVDVideoCodecFFmpeg::GetPicture ( VideoPicture * pVideoPicture )

overridevirtual

GetPicture controls decoding. Player calls it on every cycle it can signal a picture, request a buffer, or return none, if nothing applies the data is valid until the next GetPicture return VC_PICTURE

Implements CDVDVideoCodec.

◆ GetPictureCommon()

bool CDVDVideoCodecFFmpeg::GetPictureCommon ( VideoPicture * pVideoPicture )

overridevirtual

Todo: : ffmpeg doesn't seem like they know how they want to handle this.

Implements ICallbackHWAccel.

◆ HasHardware()

bool CDVDVideoCodecFFmpeg::HasHardware ( )

inlineprotected

◆ Open()

bool CDVDVideoCodecFFmpeg::Open	(	CDVDStreamInfo &	hints,
		CDVDCodecOptions &	options )

overridevirtual

Open the decoder, returns true on success Decoders not capable of running multiple instances should return false in case there is already a instance open

Todo: allow per video setting?

Implements CDVDVideoCodec.

◆ Reopen()

void CDVDVideoCodecFFmpeg::Reopen ( )

overridevirtual

Re-open the decoder. Decoder request to re-open

Reimplemented from CDVDVideoCodec.

◆ Reset()

void CDVDVideoCodecFFmpeg::Reset ( )

overridevirtual

Reset the decoder. Should be the same as calling Dispose and Open after each other

Implements CDVDVideoCodec.

◆ SetCodecControl()

void CDVDVideoCodecFFmpeg::SetCodecControl ( int flags )

overridevirtual

Codec can be informed by player with the following flags:

DVD_CODEC_CTRL_NO_POSTPROC : if speed is not normal the codec can switch off postprocessing and de-interlacing

DVD_CODEC_CTRL_HURRY : codecs may do postprocessing and de-interlacing. If video buffers in RenderManager are about to run dry, this is signaled to codec. Codec can wait for post-proc to be finished instead of returning empty and getting another packet.

DVD_CODEC_CTRL_DRAIN : instruct decoder to deliver last pictures without requesting new packets

DVD_CODEC_CTRL_DROP : this packet is going to be dropped. decoder is free to use it for decoding

Reimplemented from CDVDVideoCodec.
