As part of the LEAD Technologies 25th anniversary, we are creating 25 projects in 25 days to celebrate LEAD's depth of features and ease of use. Today's project comes from Mohamed.

What it Does

This C# project will capture, DVR and stream videos over RTSP using LEADTOOLS Version 19.

Today we released several updates to LEADTOOLS Multimedia Version 19. In particular, the H.264 encoder and RTSP Source filter are faster and offer greater flexibility.

• NVIDIA CUDA hardware acceleration (NVENC) for H.264 encoder — NVIDIA's latest graphics cards and video drivers include even better hardware acceleration than the previous generation (NVCUVENC). H.265 support for NVENC acceleration is currently in beta and LEADTOOLS is excited about adding this support to our H.265 encoder in the future.
• Automatic timestamp drift correction for AAC and H.264 encoders — An incredibly useful feature for the TV industry. With video capture and DVR applications often running for days, timestamps can begin to drift resulting in out of sync audio and video streams. LEADTOOLS' AAC and H.264 encoders can now automatically detect and correct these problems when they arise in the capture hardware.
• RTSP Source Filter callback and MaxTimeout parameter — When RTSP streams encounter connection and load-time issues, both of these features make it possible for the client to abort the process manually or after a specified amount of time.
• YUV color space support in Video Callback Filter — Customers using the Video Callback filter can now work directly with YUV data without converting it to RGB.

All of these new features are freely available to those evaluating and who have already purchased LEADTOOLS Version 19. All you need to do is download the latest setup from our website!

LEAD Technologies has worked hard on its Multimedia SDK over the past few months, adding many new features and improvements. This plethora of updates spans across the entire gamut of technology within the Multimedia SDK including playback, conversion, codecs and much more.

• FLV playback and decoding improvements
  • Increased decoding and encoding speed
  • Faster seeking in large files
  • Improved loading speed for FLV files without duration timestamps
• Improved playback and conversion of concatenated files
  • Support for reading and writing the discontinuity flag
  • Detect concatenated files
  • More efficient memory usage and disk swapping in LEADTOOLS multiplexers
• Added support for playing RTP streams with MPEG-2 packets
• Added support for playing audio from WebM demultiplexer
• New options for controlling h.264 hardware acceleration
• Added support for styling individual words with the Text Overlay filter
• New demo showing how to implement custom video rendering such as GDI or OpenGL (available in C++, C# and VB.net)
• Added ability to create 8-bit video with custom palette
• Various new features and enhancements for the following codecs, multiplexers, demultiplexers and filters
  • MPEG-2
  • h.264
  • AAC
  • WMV
  • MPG
  • AVI
  • OGG
  • DVD

How to Get These Updates

All of these features are free for all current Version 18 customers and are available in the latest Multimedia SDK download. We hope you are as excited about these updates as we are. The majority of these features were added as a result of customer feature requests, so keep them coming!
