    Precondition
    NvMediaParserCreate()
    Postcondition
    Bitstream is parsed for decoding.

    This function is called with bitstream packet NvMediaBitStreamPkt to do the decoding of current frame. If total bitstream data is not sufficient for current frame decode then it returns after copying that data in some internal buffer. Once one frame data is accumulated then it calls different callback for different puspose. NvMediaParserClientCb::BeginSequence callback will be called when it detect new sequence data and it will pass sequence information as defined in NvMediaParserSeqInfo. NvMediaParserClientCb::AllocPictureBuffer callback will be called to get frame buffer for current frame. NvMediaParserClientCb::DecodePicture callback will be called when it has complete frame data. It passes NvMediaParserPictureData to its client. NvMediaParserClientCb::DisplayPicture callback will be called when frame is ready for display. This passes the frame buffer and its timestamp. NvMediaParserClientCb::AddRef callback called to increase ref counting of frame buffer. NvMediaParserClientCb::Release callback called to decrease ref counting. NvMediaParserClientCb::GetBackwardUpdates callback called to get probability update for VP9 codec. NvMediaParserClientCb::GetDpbInfoForMetadata callback is called if error status reporting is enabled. This is pass DPB information to client. The function calls the NvMediaParserClientCb::SliceDecode callback to pass slice-level data decoding. This is used for specific hardware/codecs.

    ◆ NvMediaParserScan()

    NvMediaStatus NvMediaParserScan ( const NvMediaParser pParser,
    const NvMediaBitStreamPkt pStreamPacket 
    )

    Performs the first pass handling for encrypted content data.

    This function is called with a bitstream packet NvMediaBitStreamPkt to do the first pass handling of encrypted frame data. This function is called after NvMediaParserSetEncryption(), which passes the all encryption metadata to the parser. It calls different callbacks for different purposes. The NvMediaParserClientCb::CreateDecrypter callback is called only once for a given session to create an NvMedia video decrypter component. The NvMediaParserClientCb::DecryptHdr callback is called for pass1 handling of encrypted data. After this callback, it calls different callbacks based on hardware/codecs. NvMediaParserClientCb::GetClearHdr callback is called to get the clear header data after the NvMediaParserClientCb::DecryptHdr callback. Here it gets only frame header data to create picture info data and to do buffer management.

    Precondition
    NvMediaParserCreate()
    Postcondition
    Bitstream is parsed for decoding.

    NvMediaStatus NvMediaParserSetAttribute ( NvMediaParser pParser,
    NvMediaParserAttr  eAttributeType,
    uint32_t  uAttributeSize,
    void *  pAttribute 
    )

    Sets attributes for the decode parser object.

    Precondition
    NvMediaParserCreate()
    Postcondition
    Parser attributes are set.


    Usage considerations

    • Allowed context for the API call
      • Interrupt handler: No
      • Signal handler: No
      • Thread-safe: Yes, with the following conditions
        • Every thread should be invoked with relevant NvMediaParser object.
      • Re-entrant: No
      • Async/Sync: Sync
    • Required privileges: None
    • API group
      • Init: No
      • Runtime: Yes
      • De-Init: No

    This function is called to set specific attributes.

    Parameters
    [in]pParserThe decoder parser object that will perform the decode parsing operation.
    [in]eAttributeTypeattribute type defined in NvMediaParserAttr
    [in]uAttributeSizesize of the data type
    [in]pAttributeis the pointer to attribute.
    Returns
    NvMediaStatus The completion status of the operation. Possible values are:

    ◆ NvMediaParserSetEncryption()

    NvMediaStatus NvMediaParserSetEncryption ( const NvMediaParser pParser,
    const NvMediaAESParams *  pAesParams 
    )

    Provides the parser object with encryption metadata for the current buffer.

    Precondition
    NvMediaParserCreate()
    Postcondition
    pParser object is updated with encryption metadata.


    Usage considerations

      • Thread-safe: Yes, with the following conditions
        • Every thread should be invoked with relevant NvMediaParser object.
      • Re-entrant: No
      • Async/Sync: Sync
    • Required privileges: None
    • API group
      • Init: No
      • Runtime: Yes
      • De-Init: No
    Parameters
    [in]pParserThe decoder parser object that will perform the decode parsing operation.
    [in]pAesParamsA (pointer to a) encryption metadata structure as defined in NvMediaAESParams
    Returns
