The following tables list the members exposed by MFrameClass.
Public Methods
| Name | Description | |
|---|---|---|
 | FrameAudioGetBytes | Gets the audio plain data pointer (only local). |
| FrameAudioSaveToFile | Saves the audio to file (*.wav format is used). If file already exists then it adds audio to the end of the file. |
| FrameAVPropsGet | Gets the media properties of frame. |
| FrameAVPropsSet | Sets the media properties to frame. |
| FrameClone | Gets clone of the video frame |
| FrameConvert | Converts frame format or just scale video frame. |
| FrameCut | Cuts out part of video frame, without memory copy. |
| FrameDataGet | Gets the ancillary data by its code. |
| FrameDataGetByIndex | Gets the ancillary data by number in M_ANC_DATA structure. |
| FrameDataSet | Sets the ancillary data by its four chars code. |
| FrameOverlay | Overlay (mix) two frames with alpha, the position is from top-left corner, for 4:2:2 images (e.g. UYVY) horz position aligned by two (e.g. 21->20). Note: For ARGB32 images, alpha from images used for mix. |
| FrameRelease | Release frame buffer. Note: do it for ALL frames received by event in .Net application! |
| FrameTimeGet | Gets the frame time. |
| FrameTimeSet | Sets the frame time. |
| FrameVideoGetBytes | Gets the video plain data pointer (only local). |
| FrameVideoGetHbitmap | Gets the video HBitmap (bitmap handle). |
| FrameVideoSaveToFile | Saves the video frame to file. Method supports *.png, *.jpg, *.bmp, *.tga, *.tiff files. |
| MFAddToStream | Add a frame to a stream |
| MFAllGet | Gets all frame properties |
| MFAudioAlloc | Allocates frame's audio data |
| MFAudioChannelGetBytes | Gets audio channel's data pointer. Warning: For 20, 24, 32 integer this method returns 32 bit float data. The changes are applied only after a call of MFAudioChannelsUpdate() method |
| MFAudioChannelsUpdate | Update frame's audio channel's data or number of channels. Call this method after modification of memory that is returned by MFAudioChannelGetBytes() method. |
| MFAudioCopyTo | Copies audio channels, the bits conversion can be also performed |
| MFAudioGain | Gets audio gain in dB. |
| MFAudioGetBytes | Gets audio data pointer and data size |
| MFAudioLoadFromFile | Loads audio data from a WAV file |
| MFAudioMix | Mixes audio data |
| MFAudioMixDirect | Directly mixes audio data (audio data of source frame and of the mixed frame should have equal frequency) |
| MFAudioSaveToFile | Save audio to file (WAV format is used). If the file is exist and have WAV format then audio will be added to the end of the file. Note: format is not checked. |
| MFAudioSet | Sets frame's audio data |
| MFAVPropsGet | Gets media properties of the frame |
| MFAVPropsSet | Sets media properties for the frame. Note that width, height, row-bytes can't be changed with this method. To change them you should convert a frame. |
| MFClone | Gets a clone of the frame. See eMFrameClone for more information about clone types. |
| MFConvert | Converts the frame's format (include frame rate conversion) or just scale the video frame. |
| MFCut | Cuts out part of video frame without memory copy. nFeild <= 0->both, nField=1 -> first field, nField=2 -> second field |
| MFDataGet | Gets ancillary data by four char code e.g. 'C608'. |
| MFDataGetByIndex | Gets ancillary data by its index |
| MFDataSet | Sets ancillary data by four char code e.g. 'C608'. |
| MFFlagCheck | Checks a frame's flag |
| MFGetProcessID | Gets frame's process ID |
| MFLoad | Loads a full copy of all data (used internally for transfer data between process) |
| MFLoadFromStream | Loads a frame from a stream |
| MFObjGet | Gets an attached object by its ID |
| MFObjGetByIndex | Gets an attached object by its index. |
| MFObjSet | Sets an attached object by its ID |
| MFOverlay | Mixes frames: overlays _pFrameOverlay frame over this frame. By default audio gain is calculated based on overlay size and transparency or can be specified via 'audio_gain' property. |
| MFOverlayRect | Mixes frames - overlays _pFrameOverlay frame over this frame, the position is from top-left corner, for 4:2:2 images (e.g. UYVY) horizontal position is aligned by two (e.g. 21->20). By default audio gain is calculated based on overlay size and transparency or can be specified via 'audio_gain' props. |
| MFPrint | Prints text over the frame |
| MFResize | Resizes the frame (just scale video frame). |
| MFSave | Saves a full copy of all data (used internally for transfer data between process) |
| MFSaveToStream | Saves a frame to a stream |
| MFStrGet | Gets a string by its ID |
| MFStrGetByIndex | Gets a string by its index. |
| MFStrSet | Sets a string by its ID. |
| MFTimeGet | Gets a frame's time |
| MFTimeSet | Sets a frame's time |
| MFTransition | Makes a transition between frames |
| MFVideoGetBytes | Gets frame's video data pointer |
| MFVideoGetBytesEx | Extended method to get video bytes of a frame |
| MFVideoGetHbitmap | Gets a HBitmap for a frame |
| MFVideoSaveToFile | Saves frame's video to a file. Supported formats are: PNG, JPG, BMP, TGA, TIFF |
| MFWaitAsync | Waits until asynchronous procedure is finished |
