I used RawLiveSource to fetch the stream in the plug-in, and the first time I fetched the video data of device 1 was normal;
When I turn off the fetch stream and reopen the fetch device 2 video data, I find that the stream data is not the correct frame data.
private void OpenLiveSession()
｛
_selectedItem = Configuration.Instance.GetItem(_viewItemManager.Config.DeviceId, Kind.Camera);
if (_selectedItem == null)
return;
_rawLiveSource = new RawLiveSource(_selectedItem);
_rawLiveSource.Init();
_rawLiveSource.LiveContentEvent += RawLiveSourceLiveContentEvent;
_rawLiveSource.EnableMulticast = true;
_rawLiveSource.LiveModeStart = true;
｝
void RawLiveSourceLiveContentEvent(object sender, EventArgs e)
{
try
{
if (!Dispatcher.CheckAccess())
{
// Make sure we execute on the UI thread before updating UI Controls
Dispatcher.Invoke(new EventHandler(RawLiveSourceLiveContentEvent), new[] { sender, e });
}
else
{
var args = e as LiveContentRawEventArgs;
if (args != null)
{
if (args.LiveContent != null)
{
var rawContent = args.LiveContent as LiveSourceRawContent;
if (rawContent != null)
{
if (_stopLive || imageBox.Width == 0 || imageBox.Height == 0)
{
rawContent.Dispose();
}
else
{
int startIndex = 32;
int length = rawContent.Content.Length - startIndex;
byte[] dataSubset = new byte[length];
Array.Copy(rawContent.Content, startIndex, dataSubset, 0, length);
handle(dataSubset);
rawContent.Dispose();
}
}
}
else if (args.Exception != null)
{
}
}
}
}
catch (Exception ex)
{
EnvironmentManager.Instance.ExceptionDialog("BitmapLiveSourceLiveContentEvent", ex);
}
}
private void CloseLiveSession()
{
if (_rawLiveSource != null)
{
_rawLiveSource.LiveContentEvent -= RawLiveSourceLiveContentEvent;
_rawLiveSource.LiveModeStart = false;
_rawLiveSource.Close();
_rawLiveSource = null;
}
}
private void ModeHandler(Mode newMode)
{
if (_rawLiveSource != null)
{
CloseLiveSession();
}
switch (newMode)
{
case Mode.ClientLive:
OpenLiveSession();
break;
case Mode.ClientSetup:
break;
｝
｝
As above, when I first opened the LiveSession, I was able to get the correct data from the RawLiveSourceLiveContentEvent; Then I modify the device to trigger the ModeHandle, and the data I get from the RawLiveSourceLiveContentEvent is incorrect, the data header is correct, and the data of the body is incorrect, and it can’t be played normally.
