Member Function Documentation

AddData()

bool CDVDVideoCodecDRMPRIME::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.

Create()

std::unique_ptr< CDVDVideoCodec > CDVDVideoCodecDRMPRIME::Create ( CProcessInfo & processInfo )

static

Drain()

void CDVDVideoCodecDRMPRIME::Drain ( )

protected

GetAllowedReferences()

unsigned CDVDVideoCodecDRMPRIME::GetAllowedReferences ( )

inlineoverridevirtual

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

Reimplemented from CDVDVideoCodec.

GetBuffer()

int CDVDVideoCodecDRMPRIME::GetBuffer ( struct AVCodecContext * avctx, AVFrame * frame, int flags )

staticprotected

GetFormat()

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

staticprotected

GetName()

const char * CDVDVideoCodecDRMPRIME::GetName ( )

inlineoverridevirtual

should return codecs name

Implements CDVDVideoCodec.

GetPicture()

CDVDVideoCodec::VCReturn CDVDVideoCodecDRMPRIME::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.

Open()

bool CDVDVideoCodecDRMPRIME::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

: fix with proper device when dma-hints wayland protocol works

Implements CDVDVideoCodec.

Register()

void CDVDVideoCodecDRMPRIME::Register ( )

static

Reset()

void CDVDVideoCodecDRMPRIME::Reset ( )

overridevirtual

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

Implements CDVDVideoCodec.

SetCodecControl()

void CDVDVideoCodecDRMPRIME::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.

UpdateProcessInfo()
