RTSP_Source_CopyTimestamps_bool
urlparam: “>copyts=1”
When enabled the timestamps are copied “as is” from the input stream to the output pin (if decoding) or to the file (if recording).
RTSP_Source_UDP_LocalAddr_str
urlparam: e.g. “>localaddr=192.168.8.2”
Local IP address of a network interface used for sending packets or joining multicast groups. Useful when the computer has several network interface cards.
RTSP_Source_UDP_LocalPort_int
urlparam: e.g. “>localport=25001”
Overrides the local UDP port to bind with.

added
Possibility to register the filter in the “Video Capture Devices” list of DirectShow by specifying the “VIDEO_CAPTURE_DEVICE” option as follows:
– through the .exe installer:
DatasteadRTSPFilterInstaller.exe /option=VIDEO_CAPTURE_DEVICE
DatasteadRTSPFilterInstaller.exe /silent /option=VIDEO_CAPTURE_DEVICE
– with regsvr32.exe:
regsvr32.exe /i:VIDEO_CAPTURE_DEVICE c:\folder\DatasteadRtspSource.ax
enhanced
– faster URL connection
– lower memory consumption
fixed
– connection to DAHUA IP camera may fail
– connection to RTP://… URLs may fail
– IDatasteadRTSPSampleCallback2->SetVideoRGBOverlayCallback not working
– text overlays were not working with Unicode fonts
v7.4.1.2 – December 4, 2019
fixed
– connection time to URLs too long
changed
“Datastead URL Source” removed from the list of the video capture devices
v7.3.1.8 – October 2, 2019
fixed
– unexpected filter reconnection may occur randomly
– frame rate may decrease progressively with some URLs
– URLs having video streams encoded in H265+ or H264+ may fail to connect
v7.3.1.6 – August 26, 2019
fixed
– RTSP re-streaming feature was not working
– connection fails if a “!” character is present in the authentication user or password
– connection time takes too long with some URLs
– “rtp://…” URLs may fail to connect
– callback function set by DatasteadRTSPSampleCallback2->SetVideoRGBOverlayCallback not called
changed
FFmpeg updated to the latest version
v7.3.1.2 – May 6, 2019
added
– if an http proxy with authentication is specified,the connection through the http proxy fails
– HRESULT Action (RTSP_Action_IsURLResponding)
Tests if the source is live, without starting the URL decoding. return S_OK upon success.
– GetStr/SetStr (RTSP_Source_Axis_IrCutFilter_str)
sets or retrieve the state of the IR Cut Filter of Axis cameras
the supported values are: enabled / disabled / auto
– GetStr (RTSP_ONVIF_Info_AuxiliaryCommands_str)
retrieves the list of the auxiliary commands available for this camera, as a string made of words separated by “\r\n” characters
– SetBool (RTSP_VideoStream_Decode_KeyFrames_Only_bool, true/false)
If true, only I-Frames are decoded. Can be enabled/disabled on the fly without stopping/restarting the graph. Saves decoding CPU by previewing at 1 fps or so, depending on the GOP size (key frame spacing). Default: false
Can be enabled through the URL by adding at the end of the URL: >maxframerate=-1
fixed
– the filter may not select the best stream quality when several video streams with different compressions are available
– some URLs may take an excessive time to connect
– some RTSP URLs never open although the URL is alive
– if URL authentication is required with username but empty password, the authentication fails
– the URL authentication fails if a “@” character is present in the username or password
