This is a basic Video-On-Video project that can take two uncompressed video files and create a compressed OGG video.

- Basic Concept: Uses 4 convert
controls and uses ltmmMultiStreamSource and ltmmMultiStreamTarget to deliver
samples from first two controls to the second two controls at which copying is done using CopyMemory function.

- Input: two files (uncompressed) with same properties (Video Subtype, BitsPerPixel)

- Output: Compressed OGG file.


Attached are:

VideoOnVideo_InputUncompressed_NoAudio.zip: Video-on-Video project

- Samples_2.rar Two small sample files (put them in c:\ to test).

This is a modified edition of the same demo. It includes the following improvements:
1. The output is no longer restricted to the OGG format. The project now creates MCMP-compressed AVI files, but can be modified to produce OGG if needed.

2. The output file now preserves audio from the input. The previous demo produced video-only files.

Both projects use LEADTOOLS Multimedia v15 and and are modified versions of the ConcatSameSize demo that ships with the toolkit.

Similar code can be used with LEADTOOLS Multimedia 16 and 17 without change.

The attached demo uses LEADTOOLS Multimedia v17 .Net programming interface. The demo uses 3 convert controls and ltmmMultiStreamSource and ltmmMultiStreamTarget to deliver samples from first two controls to the third control. Also, I am attaching two uncompressed OGG files for testing.

Notes:
1. This demo is based on the C# concatenate same size demo that ships with the SDK. To run the demo, copy it to the
[LEADTOOLS Multimedia 17]\Examples\Ltmm\Dotnet\CS folder.

2. The demo works only with uncompressed video files.

3. To get the correct results, you should add the large video to the conversion list (1.ogg) before adding the small video (2.ogg).

Thanks,
