Codec id v_mpeg4/iso/avc




















SHOULD assume that all Codec Mappings they create might become standardized, public, commonly deployed, or usable across multiple implementations. The data are stored in little-endian format like on IA32 machines. Note there are differences how b-frames are handled in these native streams, when being compared to a VfW created stream, as here there are no dummy frames inserted, the frame order is exactly the same as the coding order, same as in MP4 streams.

Description: The Matroska video stream will contain a demuxed Elementary Stream ES , where block boundaries are still to be defined. For legacy reasons Block Addition Mappings are preferred , the AVCDecoderConfigurationRecord structure MAY be followed by an extension block beginning with a 4-byte extension block size field in big-endian byte order which is the size of the extension block minus 4 excluding the size of the extension block size field and a 4-byte field corresponding to a BlockAddIDType of mvcC followed by a content corresponding to the content of BlockAddIDExtraData for mvcC.

Initialization: The Private Data contains the first three Theora packets in order. The lengths of the packets precedes them. The actual layout is:. Description: VP8 is an open and royalty free video compression format developed by Google and created by On2 Technologies as a successor to VP7.

Description: VP9 is an open and royalty free video compression format developed by Google as a successor to VP8. Description: FFV1 is a lossless intra-frame video encoding format designed to efficiently compress video data in a variety of pixel formats.

Compared to uncompressed video, FFV1 offers storage compression, frame fixity, and self-description, which makes FFV1 useful as a preservation or intermediate video format.

Draft FFV1 Specification. The floats are stored as defined in [! Description: The main developer for musepack has requested that we wait until the SV8 framing has been fully defined for musepack before defining how to store it in Matroska. The private data is void??? Corresponding ACM wFormatTag : 0x ; channel number have to be read from the corresponding audio element. Description: The ac3 frame header has, similar to the mpeg-audio header a version field.

Normal ac3 is defined as bitstream id 8 5 Bits, numbers are Everything below 8 is still compatible with all decoders that handle 8 correctly. Everything higher are additions that break decoder compatibility.

The private data is void. Description: DTS Express a. LBR audio streams. Description: DTS Lossless audio that does not have a core substream. Initialization: The Private Data contains the first three Vorbis packet in order. These include the first header packet containing only the word fLaC as well as all metadata packets. Description: Channel number and sample rate have to be read from the corresponding audio element.

The header and seektable are dropped. Description: The Wavpack packets consist of a stripped header followed by the frame data. For more details, check the WavPack muxing description. Each event is stored in its own Block. Description: This is mostly defined, but not typed out yet.

It will first be available on the USF specification in Subtitles. The timestamp in the block header of Matroska indicates the start display time, the duration is set with the Duration element. Description: This is the graphical subtitle format used in the Digital Video Broadcasting standard. Description: The same subtitle format used on DVDs. Supported is only format version 7 and newer. VobSubs consist of two files, the. Description: VP8 is an open and royalty free video compression format developed by Google and created by On2 Technologies as a successor to VP7.

VobSubs consist of two files, the. All remaining lines but the ones containing timestamps and file positions are put into the CodecPrivate element. For each line containing the timestamp and file position data is read from the appropriate position in the.

Description: This is the textual subtitle format used on Blu-rays. For more information, see hdmv-presentation-graphics-subtitles on HDMV graphics presentation. Description: A subtitle format developed for ogg.

The mapping for Matroska is described on the Xiph wiki. As for Theora and Vorbis, Kate headers are stored in the private data as xiph-laced packets.
