Version Changes: 22 to 23
The following members have been added:
| Name | Description |
|---|---|
Leadtools.Multimedia.CameraControlProperty.Auto_Exposure_Priority |
Specifies the auto-exposure priority property. Auto-exposure priority determines whether the camera can dynamically vary the frame rate depending on lighting conditions. A value of 0 keeps the frame rate constant. A value of 1 allows the frame rate to dynamically vary. The camera must be in auto-exposure mode for the auto-exposure priority mode to be a valid option. The default value is 0. |
Leadtools.Multimedia.CameraControl.LowLightCompensation |
Gets or sets the camera's low light compensation setting. |
Leadtools.Multimedia.CaptureCtrl.CaptureDIB |
Captures a device independent bitmap. |
Leadtools.Multimedia.CaptureCtrl.GetStillDIB(int) |

| Leadtools.Multimedia.SourceFormatType.ONVIF | Source format is ONVIF. |
| Leadtools.Multimedia.PlayDlg.SourceAndSplitter | Specified the source and splitter (demultiplexer) filters properties dialog box. |
| Leadtools.Multimedia.LoadStatusEventCode.AM_LOADSTATUS_PROGRAM_COUNT_DETECTED | Indicates the number of programs that have been detected. Use this event to set the current program. |
| Leadtools.Multimedia.LoadStatusEventCode.AM_LOADSTATUS_PROGRAM_INFO_DETECTED | The LEAD MPEG-2 Transport Demultiplexer sends this event when it has received more information (metadata) about the available programs in the source. This is sent in response to receiving and parsing Program and System Information Protocol (PSIP) tables. These tables contain information about the name of the TV channel associated with each program, etc. You can call ILMMpgDmx.GetProgramInfoAsLong and ILMMpgDmx.GetProgramInfoAsString to get this extra information. See for more information on the ILMMpgDmx interface. |
| Leadtools.Multimedia.LoadStatusEventCode.AM_LOADSTATUS_VIDEO_SIZE_CHANGED | The video size has changed. This event is usually received while playing DVDs. It is common for DVDs to have video of one size in the menu and another size in the main title. |
| Leadtools.Multimedia.LoadStatusEventCode.AM_LOADSTATUS_DATA_STOPPED |
The LEAD RTSP Source sends this event every second if it has stopped receiving data from the remote server. It indicates some data has been received in the past, but it has stopped arriving. Normally, a server will send an end of stream notification to indicate that no more data is expected. In this case, no end of stream notification has been received, so there is a high possibility the connection was lost. This event is often followed by the ltmmAM_LOADSTATUS_CONNECTION_LOST event.
Param2 is the number of milliseconds elapsed since the last time the filter received any data. The toolkit will use an ILMSrcCallback interface to implement these notifications. If you set your own callback interface using the ILMRTSPSrc::CallbackObj property, you will not get these notifications anymore. |
| Leadtools.Multimedia.LoadStatusEventCode.AM_LOADSTATUS_CONNECTION_LOST |
The LEAD RTSP Source sends this event when playback has stopped abnormally because the connection to the server has been lost. It is an indication of some kind of error. This event is not sent if the playback stopped normally by reaching the end of stream.
The toolkit will use an ILMSrcCallback interface to implement these notifications. If you set your own callback interface using the ILMRTSPSrc::CallbackObj property, you will not get these notifications anymore. |
| Leadtools.Multimedia.TargetFormatType.RTSP | Target format used to transmit multimedia streams using the LEAD RTSP Sink filter. Can use LEAD H264 Video Encoder, LEAD H265 Video Encoder and LEAD AAC Encoder. You only need to use this target format if you use the low level functions to implement an RTSP server. See the "Create an RTSP Server" link below for more information. |
| Leadtools.Multimedia.TargetFormatType.MPEG2TransportDICOM | DICOM video format with embedded H.264/AVC video and MPEG Audio (Layer 1, 2 or 3), AAC, AC3 or LPCM audio content in an MPEG-2 Transport container. |
| Leadtools.Multimedia.TargetFormatType.ISODICOM | DICOM video format with embedded H.264/AVC video and AAC audio content in an ISO/MP4 container. |

| Leadtools.Multimedia.ErrorCode.LTMM_E_DICOM_ERROR_FIRST |
The interval LTMM_E_DICOM_ERROR_FIRST .. LTMM_E_DICOM_ERROR_LAST interval is used to return a LEADTOOLS DICOM error. Unlike LEADTOOLS still image errors, DICOM errors are positive.
The error is (<HRESULT_CODE> - LTMM_E_DICOM_ERROR_FIRST). The error code range is 0x8005E000 - 0x800EFFF. So, if the error is 0x8005E002, then the LEADTOOLS DICOM error is '-2' (not enough memory). |
| Leadtools.Multimedia.ErrorCode.LTMM_E_DICOM_ERROR_LAST | Last DICOM error. See LTMM_E_DICOM_ERROR_FIRST for more details. |
| Leadtools.Multimedia.ErrorCode.LTMM_E_STILLIMAGE_ERROR_FIRST |
The interval LTMM_E_STILLIMAGE_ERROR_FIRST .. LTMM_E_STILLIMAGE_ERROR_LAST interval is used to return a LEADTOOLS still image error code.
The error is (<HRESULT_CODE> - LTMM_E_STILLIMAGE_ERROR_FIRST). The error code range is 0x8005F000 - 0x8005FFF. So, if the HRESULT is 0x8005F009, then the LEADTOOLS error is '-9' (error loading file). |
| Leadtools.Multimedia.ErrorCode.LTMM_E_STILLIMAGE_ERROR_LAST | Last Still Image error. See LTMM_E_STILLIMAGE_ERROR_FIRST for more details. |

The LEAD RTSP Source and Sink filters now support H265 video compression.
The LEAD RTSP Source now supports a MaxTimeout parameter indicating the maximum amount of time it will wait for data.
The LEAD RTSP Source now sends periodic EC_LOADSTATUS event notifications while waiting for data allowing you to abort the wait.
You can now play HTTP JPEG streams.
The LEAD MPEG2 Encoder (3.0) can now add Precision Time Stamps to the encoded stream.
The LEAD H264 Encoder (4.0) can now add Precision Time Stamps to the encoded stream.
The LEAD MPEG2 Transport Multiplexer can now add to, modify or remove Precision Time Stamps from streams using MPEG2 or H264 video compression.
The LEAD MPEG2 Transport Multiplexer now supports a low latency mode.
You can now set the PID of the streams generated by LEAD MPEG2 Transport Multiplexer.
The LEAD Video Callback filter now supports YUV color spaces.
The LEAD H264 Encoder and LEAD AAC Encoder now support automatic timestamp drift correction during capture.
The LEAD H264 Encoder now supports the new NVIDIA CUDA hardware acceleration (NVENC).
The LEAD H264 Decoder now supports Intel Quick Sync Video and NVIDIA CUDA hardware acceleration.
The LEAD MPEG2 Decoder now supports Intel Quick Sync Video and NVIDIA CUDA hardware acceleration.
The LEAD ISO Multiplexer now supports YUY2, UYVY, JPEG and PCM input
The LEAD ISO Multiplexer now supports VIDEOINFOHEADER2 video (video with non-square pixels)
The LEAD MCMP/MJPEG Codec now supports VIDEOINFOHEADER2 video (video with non-square pixels)
You can now achieve smooth reverse playback by using MP4 files with JPEG compression.
You can now stream live streams using the Media Streaming SDK (first version of the Media Streaming SDK could stream only files).
The LEAM MPEG2 Transport UDP Source has a new Latency property to achieve smooth playback of raw RTP streams with gaps
The LEAD RTSP Source has a new EnableSessionUI property for enabling/disabling the message box used to enter the username/password needed to play secure RTSP streams.
There is improved support for capturing from HDTV capture devices.
