New White Paper: Harnessing MPEG-2 Transport Stream with LEADTOOLS

Streaming audio/video multimedia content takes a prominent place in today’s culture. It is everywhere from home entertainment services, Unmanned Aerial Vehicles (UAVs), security and surveillance systems, and even baby monitors. What you might not know is that one format powers a large majority of those systems and products. MPEG-2 Transport Stream is at the heart of many streaming technologies you use and benefit from on a daily basis.

Naturally, LEADTOOLS has some powerful SDK features that can help you implement and take advantage of the many benefits of MPEG-2 Transport Stream. Check out this month’s white paper for a detailed look into the world of MPEG-2 Transport Stream and how to use it in your application to send and receive live audio/video streams with KLV metadata, DVR and more.

Harnessing MPEG-2 Transport Stream with LEADTOOLS
Like many booming industries, audio and video streaming is supported by a large cast of technologies serving in a wide variety of roles from high-end military drones to home entertainment and everything in between. The cast takes the form of audio and video compression algorithms within codecs, multiplexers, demultiplexers and the applications that bring them to life. Of these, MPEG-2 Transport Stream has emerged as one of the most versatile and widely used video streaming formats. This white paper will dive into the many advantages and uses for MPEG-2 Transport Stream and how to incorporate it into your application with LEADTOOLS Multimedia SDKs.

We have also published this white paper on The CodeProject if you would like to read it in an online format.

How to Combine Video and Audio from Separate Sources

LEADTOOLS Multimedia SDK has made a name for itself by offering high level controls that take the complexity out of developing DirectShow and Media Foundation applications. Most core operations such as conversion, capture and playback can be done with only a few lines of code. In addition to the high level features, LEADTOOLS is flexible enough for any advanced application with more difficult scenarios and still offers as much or as little control as desired over the graphs and topologies under the hood.

The ConvertCtrl is a perfect example of this. By setting a source file, destination file and format you can make an audio/video conversion application in minutes. Developers who wish to dive deeper can supply their own media samples and process the conversion frame by frame.

That is precisely the scenario described in the following example. Usually, conversion is a one to one process where you have a single file being converted to another single file. But what happens if you have your audio and video in separate files? This can be accomplished by employing three ConvertCtrl objects: one for decoding the audio file, one for decoding the video file, and the final control for splicing them together. In between the decoding and encoding you will get the media samples, merge them into a MultiStreamSource and use that source in the 3rd ConvertCtrl:

vidConvert = new ConvertCtrl();
audConvert = new ConvertCtrl();
//Init the SampleTargets. The Video and Audio data from our files will write to these.
SampleTarget vidTarget = new SampleTarget();
SampleTarget audTarget = new SampleTarget();
//Set the Media Type of the VideoTarget to Video
MediaType mt = new MediaType();
mt.Type = Constants.MEDIATYPE_Video;
vidTarget.SetAcceptedMediaType(mt);
vidConvert.TargetObject = vidTarget;
//Clear
mt = null;
//Set the Media type for our AudioTarget to Audio.
mt = new MediaType();
mt.Type = Constants.MEDIATYPE_Audio;
audTarget.SetAcceptedMediaType(mt);
audConvert.TargetObject = audTarget;
//Clear
mt = null;
//Set the ConvertCtrls to point to the Files as their sources.
vidConvert.SourceFile = videoFile;
audConvert.SourceFile = audioFile;
//Start running the two conversion controls. These are writing to the Sample Targets.
vidConvert.StartConvert();
audConvert.StartConvert();
//Enter the Combine Method
CombineVideoAndAudio(vidTarget, audTarget);

This is just the beginning of the process. To see what goes on inside the CombineVideoAndAudio function and try it out for yourself, you can download the full example from the original forum post.

New White Paper: Implementing a Standardized PDF/A Document Storage System with LEADTOOLS

This month’s white paper is an extremely practical one. In fact, we even had a few conversations with customers at last week’s HIMSS conference about this very subject. Document archival has been around for quite a while now, but as archives grow and systems become more spread out and the client device ecosystem is much more diverse, standardizing your document archival system is becoming critical.

If you have need for end-to-end PDF and PDF/A functionality including OCR, Virtual Printing, HTML5 viewing and more, you will benefit greatly from our March white paper!

Implementing a Standardized PDF/A Document Storage System with LEADTOOLS
Electronic document archival has evolved far beyond the simple days of scanning a paper document and saving it as an image or PDF. Nowadays, many documents don’t even start in physical form and could be one of many open or proprietary formats. Adding to the disparity caused by varying file formats is how and where files are stored. Many enterprises have their documents spread around numerous “data islands” including local computers, networked file shares and cloud services. This white paper will explore how to take full advantage of PDF/A as your universal document storage format by using the state of the art technology within LEADTOOLS Document Imaging SDKs.

We have also published this white paper on The CodeProject if you would like to read it in an online format.

How to Load a DICOM File From a Byte Array

More often than not, DICOM files are loaded from a location on disk due to the size and complexity of the files. However, no environment and scenario is the same and we periodically get requests regarding how to load DICOM files from memory, more specifically a byte[] rather than a Stream. Due to the way that .NET garbage collection works we must use a .NET GCHandle object when passing an IntPtr to the overloaded DicomDataSet.Load function.

private byte[] loadedFile; // byte array for DICOM file from database, server, etc.
private DicomDataSet dicomDS;
private DicomElement element;
// Pin object so it is not garbage collected before work is done.
GCHandle gch = GCHandle.Alloc(loadedFile);
// Load DicomDS from byte[] using IntPtr of array.
dicomDS.Load(Marshal.UnsafeAddrOfPinnedArrayElement(loadedFile, 0),
loadedFile.Length, DicomDataSetFlags.None);
// Unpin object.
gch.Free();
// Get image from DicomDS.
element = dicomDS.FindFirstElement(null, DicomTag.PixelData, true);
rasterImageViewer1.Image = dicomDS.GetImage(element, 0, 0,
Leadtools.RasterByteOrder.Gray, DicomGetImageFlags.None);
