    Types

    type Demuxer

    type Demuxer struct {
    	av.Demuxer
    	Options
    	// contains filtered or unexported fields
    }

      Wrap transcoder and origin Demuxer into new Demuxer. Read this Demuxer will do transcoding automatically.

      func (*Demuxer) Close

      func (self *Demuxer) Close() (err error)

      func (*Demuxer) ReadPacket

      func (self *Demuxer) ReadPacket() (pkt av.Packet, err error)

      func (*Demuxer) Streams

      func (self *Demuxer) Streams() (streams []av.CodecData, err error)

      type Muxer

      type Muxer struct {
      	av.Muxer // origin Muxer
      	Options  // transcode options
      	// contains filtered or unexported fields
      }

        Wrap transcoder and origin Muxer into new Muxer. Write to new Muxer will do transcoding automatically.

        func (*Muxer) Close

        func (self *Muxer) Close() (err error)

        func (*Muxer) WriteHeader

        func (self *Muxer) WriteHeader(streams []av.CodecData) (err error)

        func (*Muxer) WritePacket

        func (self *Muxer) WritePacket(pkt av.Packet) (err error)

        type Options

        type Options struct {
        	// check if transcode is needed, and create the AudioDecoder and AudioEncoder.
        	FindAudioDecoderEncoder func(codec av.AudioCodecData, i int) (
        		need bool, dec av.AudioDecoder, enc av.AudioEncoder, err error,
        	)
        }

        type Transcoder

        type Transcoder struct {
        	// contains filtered or unexported fields
        }

        func NewTranscoder

        func NewTranscoder(streams []av.CodecData, options Options) (_self *Transcoder, err error)

        func (*Transcoder) Close

        func (self *Transcoder) Close() (err error)

          Close transcoder, close related encoder and decoders.

          func (*Transcoder) Do

          func (self *Transcoder) Do(pkt av.Packet) (out []av.Packet, err error)

            Do the transcode.

            In audio transcoding one Packet may transcode into many Packets packet time will be adjusted automatically.

            func (*Transcoder) Streams

            func (self *Transcoder) Streams() (streams []av.CodecData, err error)

              Get CodecDatas after transcoding.
