The Stream and PortStream parameters follow the reference-counting conventions for COM objects.Īvailable in Windows Vista and later Windows operating systems. The DataFormat parameter, which specifies the data format of the stream, points to one of the following audio-specific, extended versions of the KSDATAFORMAT structure: For more information, see related methods IMiniportWaveRTStream::SetState and IMiniportWaveRTStream::GetPosition. The NewStream method sets the initial state of the stream to KSSTATE_STOP and its initial position to 0. Otherwise, the method returns an appropriate error status code. NewStream returns STATUS_SUCCESS if the call was successful. For more information, see the following Remarks section. Pointer to a KSDATAFORMAT structure that specifies the data format of the new stream. This parameter is TRUE for a capture (input) stream, and FALSE for a playback (output) stream. Specifies a Boolean value that indicates whether to create a capture stream or a render stream. Newstream is helping media companies to get more news stories and manage their content producers in a hassle-free and cost-effective way. For more information about filter descriptors, see the Filter Factories topic.
NEWSTREAM MEDIA DRIVER
If the filter descriptor of the WaveRT miniport driver specifies a total of n pin factories on the filter, valid values for the Pin parameter are in the range 0 to n-1. Specifies a pin ID that identifies the pin to be opened. The caller specifies a valid, non- NULL pointer for this parameter. This parameter points to a caller-allocated pointer variable, into which the NewStream method writes a pointer to the IMiniportWaveRTStream interface of the new stream object. I'm checking UiUpload processor to no luck as HttpFileCollection only has read-only streams.The NewStream method creates a new instance of a WaveRT stream object.
Looking at the issue I found above, it is apparent that I need to find an alternative. To change streams, tap on the white icon located on the right of the dark blue bar.
NEWSTREAM MEDIA UPDATE
Is it safe to update MediaStream in item:saved event?.Though I believe it should not, the custom data provider developer points to it. Is it possible the EventDisabler is the cause of the issue above?.It also causes a custom data provider is not firing properly. When the SetStream is called several times (due lock changes for instance), the media attached into the item will be lost on the backend UI. ItemChanges itemChanges = (ItemChanges)itemChangesObj
Object itemChangesObj = parameters.FirstOrDefault(x => x is ItemChanges) IEnumerable parameters = evtArgs.Parameters private bool _IsLockChange(SitecoreEventArgs evtArgs) However the item changes seems did not say anything for MediaStream changes. How should i detect that the changes is only the MediaStream?Ĭurrently i can probe lock changes by checking the ItemChanges from SitecoreEventArgs.Parameters. It seems does not play nicely with Sitecore event in overall (it called numerous times including on lock changes, last updates, etc). Log.Error("Unable to process media stream due to general error.", ex, this) Fail safe, should not fails the entire Content Editor or Codes Log.Info(string.Format("Begin media stream processing for )", MediaStream mediaStream = media.GetStream() Media media = MediaManager.GetMedia(item) Item item = Event.ExtractParameter(evtArgs, 0) SitecoreEventArgs evtArgs = args as SitecoreEventArgs
NEWSTREAM MEDIA CODE
The code is roughly like this: public void OnItemSaved(object sender, EventArgs args) I had implemented a item:saved event handler that updates the MediaStream of a MediaItem.
