getAudioInfo()

virtual AudioInfoFormat getAudioInfo ( )

pure virtual

Common audio info (sample_rate/channels/bits_per_sample), extended with the parsed codec format tag.

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

bool isNotifyActive ( )

inlineinherited

Checks if the automatic AudioInfo update is active.

isNotifyActive() [2/2]

bool isNotifyActive ( )

inlineinherited

Checks if the automatic AudioInfo update is active.

isValid()

virtual bool isValid ( const uint8_t * data, size_t len )

inlinevirtual

True if data (the start of the stream, as handed to the first write()) looks like this demuxer's own container format - content-sniffing, not a guarantee (see the concrete class for exactly what's checked). Used by MultiVideoDemuxer to auto-select a registered demuxer (MultiVideoDemuxer.h); not otherwise part of the write()/parse path. Default false, matching VideoDecoder::isValid()'s own default - a demuxer not meant to be auto-detected this way simply never overrides it.

Reimplemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, and DemuxerMTS.

mime()

const char * mime ( )

overridepure virtual

Provides the MIME type of the audio track (e.g. "audio/wav", "audio/aac") - fulfills MimeSource::mime(), so any Demuxer can be passed directly to e.g. MultiDecoder::setMimeSource() to hint the audio codec instead of relying on sniffing the raw byte stream.

Implements AudioDecoder.

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

mimeVideo()

virtual const char * mimeVideo ( )

pure virtual

The container's MIME type (e.g. "video/avi", "video/mp4").

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

setOutputAudio()

virtual void setOutputAudio ( Print & out )

pure virtual

Defines the audio output stream - e.g. an EncodedAudioStream wrapping an AudioDecoder that matches the track's codec, or any other Print if you want the raw payload as-is.

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

setOutputVideo() [1/2]

virtual void setOutputVideo ( Print & out )

pure virtual

Defines the video output - e.g. a VideoOutput implementation, or any other Print if you want the raw payload as-is.

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

setOutputVideo() [2/2]

virtual void setOutputVideo ( VideoOutput & out )

pure virtual

Defines the video output - the VideoOutput-specific counterpart of setOutputVideo(Print&), for a target like PacedVideoOutput/ OutputTinyGPU/OutputOpenCV that implements VideoOutput but not Print (the two are unrelated types - see VideoFrameMeter's own comment). Part of the base interface (unlike other concrete-class-specific extras) so code holding only a Demuxer& (e.g. VideoPlayer) can wire it to an arbitrary VideoOutput& without knowing the concrete container format - every current demuxer already implemented this identically before it was pulled up into the interface.

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

setSendWavHeader()

virtual void setSendWavHeader ( bool flag )

pure virtual

Overrides the automatic decision of whether a synthetic WAV header is sent to the audio output before any audio payload - see the concrete class for the default heuristic.

Implemented in DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, and MultiVideoDemuxer.

videoInfo()

VideoInfo videoInfo ( )

inlineoverridevirtual

Fulfills VideoInfoSource::videoInfo(), so any Demuxer can be passed directly to e.g. OutputOpenCV::setVideoInfoSource() - note the reported 'format' is the container's codec (e.g. H264), not necessarily what ends up written to a raw-picture VideoOutput/Print (that depends on whatever decoder sits between the demuxer and the output); consumers that care about the decoded format should still set it explicitly and rely on this only for width/height.

Implements VideoInfoSource.

write() [1/2]

virtual size_t write ( const uint8_t * data, size_t len )

pure virtualinherited

Implemented in AACDecoderFAAD2, AACDecoderFAAD, AACDecoderFDK, AACDecoderHelix, AACEncoderFAAC, AACEncoderFDK, AACEncoderVO, AC3AudioDecoder, ADPCMDecoder, ADPCMDecoderXQ, ADPCMEncoder, ADPCMEncoderXQ, ADTSDecoder, AMRNBDecoder, AMRNBEncoder, AMRWBDecoder, AMRWBEncoder, APTXDecoder, APTXEncoder, CodecNOP, CodecNOP, BinaryContainerDecoder, BinaryContainerEncoder, Codec2Decoder, Codec2Encoder, CodecChain, CodecNOP, ContainerM4A, CopyDecoder, CopyEncoder, DecoderAdapter, DecoderALAC, DecoderBase64, DecoderBasic, DecoderFloat, DecoderL16, DecoderL8, DecoderNetworkFormat, DemuxerAVI, DemuxerMP4, DemuxerMPG, DemuxerMTS, DSFDecoder, DSFEncoder, EncoderALAC, EncoderBase64, EncoderBasic, EncoderFloat, EncoderL16, EncoderL8, EncoderNetworkFormat, FLACDecoderFoxen, FLACEncoder, G711Decoder, G711Encoder, G722Decoder, G722Encoder, G729Decoder, G729Encoder, G7xxDecoder, G7xxEncoder, GSMDecoder, GSMEncoder, H264RtpEncoder, ILBCDecoder, ILBCEncoder, JPEGRtpEncoder, LC3Decoder, LC3Encoder, MetaDataFilterDecoder, MetaDataFilterEncoder, MP2Decoder, MP3DecoderHelix, MP3DecoderMAD, MP3DecoderMini, MP3EncoderLAME, MP3EncoderShine, MP3ParserEncoder, MTSDecoder, MTSDecoderTSDemux, MultiDecoder, MultiVideoDemuxer, OggContainerDecoder, OggContainerEncoder, OpusAudioDecoder, OpusAudioEncoder, OpusMultiStreamAudioDecoder, OpusMultiStreamAudioEncoder, OSCContainerDecoder, OSCContainerEncoder, SBCDecoder, SBCEncoder, VorbisDecoder, WAVDecoder, WAVEncoder, and WavIMADecoder.
