Microsoft MPEG- 2 Video Encoder (Windows)The Microsoft MPEG- 2 Video Encoder filter encodes MPEG- 2 and MPEG- 1 video. To encode and multiplex audio/video streams, use the Microsoft MPEG- 2 Encoder filter, which encapsulates the functions of both this filter and the Microsoft MPEG- 2 Audio Encoder filter. Note. В В This filter is not supported on IA- 6. В Filter Information.

The filter supports the following properties through ICodec. API. В It is recommended to set properties in the following order: AVEnc. Common. Format. Constraint. AVEnc. Codec. Type.
AVEnc. MPVProfile. AVEnc. MPVLevel. AVEnc. Input. Video. System. Set the remaining properties in any order. However, see GOP Structure.)It is possible to set properties while the filter graph is running. There is a delay of at least one GOP before the new settings take effect. Encoder Operation.
When encoding MPEG- 1 video, the encoder automatically sets the 1- bit constrained_parameters_flag code in the sequence header if all constraints are met. If needed, the encoder rounds up the input video dimensions so that the output video dimensions match the MPEG requirements. For progressive video, the output dimensions are rounded up to a multiple of 1. For interlaced video, width is rounded up to a multiple of 1. This round- up operation uses padding as needed. If the video is interlaced, the encoder performs automatic telecine (3: 2 pull- down) detection.
The input video can contain field picture pairs, in addition to interlaced frames. The encoder's internal format is 4: 2: 0 IYUV (identical to I4. It can perform color conversion from YUY2, YV1. UYVY, and RGB- 2. To constrain the bitstream to a target format (DVD or VCD), set the AVEnc. Common. Format. Constraint property.
If this property has a value other than GUID_AVEnc. Common. Format. Un. Specified, the encoder limits the MPEG syntax to that allowed by the target format.
For live encoding, set the AVEnc. Common. Quality. Vs. Speed property to zero. This causes the encoder to optimize for speed. Encoding Modes. The encoder supports several encoding modes: One- pass constant bit rate (CBR). One- pass quality- based variable bit rate (VBR), using a constant quantizer step size.
In this mode, the encoder attempts to meet a target quality level, up to a maximum bit rate. One- pass peak- constrained VBR. In this mode, the encoder attempts to achieve a target average bit rate within certain internal limits.
To configure the encoding mode, set the following properties: В Note. В В Two- pass VBR is not supported. В Aspect Ratio. The display aspect ratio and pixel aspect ratio (PAR) are related by the following formula: Display aspect ratio = PAR Г— (picture width / picture height)The encoder uses this formula to calculate the value of pel_aspect_ratio for MPEG- 1 bitstreams or aspect_ratio_information for MPEG- 2 bitstreams. See ISO/IEC 1. 11.
ISO/IEC 1. 38. 18. The encoder tries the following settings, in order: If the application sets the AVEnc. Video. Pixel. Aspect. Ratio property at any time before the filter graph runs, this property is used for the PAR. Otherwise, if the dw. Pict. Aspect. Ratio.
X and dw. Pict. Aspect. Ratio. Y members of the VIDEOINFOHEADER2 structure are non- zero, these members are used for the display aspect ratio, and the PAR is calculated from the display aspect ratio. If none of these values is present, the PAR is assumed to be 1. In live encoding mode (AVEnc. Common. Quality. Vs. Speed equal to zero), the display aspect ratio must be either 4: 3 or 1.
If the computed display aspect ratio is not 4: 3 or 1. GOP Structure. To specify the group of picture (GOP) structure, set the following properties in order: AVEnc.
MPVGOPSize. AVEnc. Video. Max. Keyframe.
Distance. AVEnc. MPVDefault. BPicture. Count. Based on these settings, the encoder produces one of the following GOP structures: В The default GOP structure is IBBPBBP.. GOP size of 1. 5 frames. If the application constrains the target format to DVD (through the AVEnc. Common. Format. Constraint property) and sets the AVEnc.
Input. Video. System property to NTSC or PAL, the encoder supports the following GOP sizes: Video System. Valid GOP Sizes. Default GOP Size. NTSC1- 1. 81. 8 (3. PAL1- 1. 51. 5 (3. В Codec Property Change Lists. Setting the value of one codec property can change the valid range of another property.
For example, constraining the target format restricts the average bit rate.) Whenever the application sets a property, the encoder checks if any other properties now fall outside their valid range. If so, the encoder resets that property to its new default value. To receive notifications when this occurs, do the following: Call ICodec. API: :Register. For. Event with the value CODECAPI_CHANGELISTS. Use the IMedia. Event. Ex interface to monitor events from the filter graph.
If the range or default value of a property changes, the encoder sends an EC_CODECAPI_EVENT event with a list of changed properties. IEncoder. API Support. For backward compatibility, the filter supports the following properties through the IEncoder. API interface: В When setting the ENCAPIPARAM_BITRATE_MODE property, the values are mapped as follows: ENCAPIPARAM_BITRATE_MODEAVEnc. Common. Rate. Control. Mode. Constant. Bit.
