Leadtools.Multimedia.SourceFormatType.RTSP Source format is RTSP.
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.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.
