LEADTOOLS Media Foundation C API Introduction

Summary

The LEADTOOLS Media Foundation C API provides developers with a full range of tools required to create professional, high-quality multimedia applications.

The API adds multimedia functionality such as Capture, Play, and Convert, as well as the latest Media Foundation filters and multimedia file support.

It allows loading and converting many common file formats, such as AVI, OGG, FLV, WMA, WMV, MP4, MKV, 3GP, MP3, WAV, FLAC, MPEG-2, and others. It also allows converting to common media foundation file formats, such as AVI, WMV, MP4, MKV, 3GP, MP3, WAV, FLAC, MPEG-2, and Fragmented MP4.

Key Features

LEADTOOLS Media Foundation SDK

The LEADTOOLS toolkit is flexible and gives you full control over the input, middle, and output samples:

Data can be input from:

Data can be output to:

Input streams can be complex, but once you set the stream URL as the source, the toolkit handles the rest. The output is handled in the same way: set the output to a URL and the toolkit will take care of streaming the data.

AVI (Audio Video Interleave), a file format defined by Microsoft, is the most common format for audio/video data on PCs. AVI files can have one or more video streams, and one or more audio streams. The video and audio streams can be compressed using various compressors (MCMP, JPEG, MCMW, MJ2K, H263, H264, MPEG-2, MPEG-1, MPEG-4, Vorbis, MP3, AC3, AAC, and many others). Each compressed file needs a decompressor to be played or converted. This means that even though two files have the same extension they may not be similar. You need to have both the audio and video decompressors to play back both streams.


Decompressor is also known as a decoder, this is a module or algorithm to decompress data.


Decoder is also known as a decompressor, this is a module or algorithm to decompress data.


WMV (Windows Media Video) is a file format developed by Microsoft. WMV files have audio and video streams. The video and audio streams can be compressed using various compressors (MCMP, JPEG, MCMW, MJ2K, H263, H264, MPEG-2, MPEG-1, MPEG-4, Vorbis, MP3, AC3, AAC,and many others). If you cannot play the file then you do not have the codec to decompress the file and the file cannot be converted.


Codec is a COmpressor combined with a DECompressor, or encoder and a decoder, which allows you to both compress and decompress that same data.


Encoder is also known as a compressor, this is a module or algorithm to compress data. Playing that data back requires a decompressor, or decoder.


The WAVE file format is used to store digital audio data in raw form and is a standard CD quality audio format that requires a large amount of memory (10 MB for 1 minute).


OGG is the name of Xiph.org's container format for audio, video, and metadata. Its default audio compressor is called Vorbis. Vorbis compression offers better quality than MP3 and yields a higher compression ratio. Ogg Vorbis is different from other formats because it is an open standard, open, and unpatented. OGG files can have one or more video streams and one or more audio streams. The video and audio streams can be compressed using various compressors (MCMP, JPEG, MCMW, MJ2K, H263, H264, MPEG-2, MPEG-1, MPEG-4, Vorbis, MP3, AC3, AAC and many others). Each compressed file will need a decompressor to be played or converted. This means that even though two files have the same extension they may not be similar. You need to have both the audio and video decompressors to play back both streams.


Flash Version 6 format files have the extension .FLV. They use the FLV multiplexer, H.263 video compression and MP3 audio compression


Flash Version 9 format files have the extension .MP4 or .F4V. They are also called "Flash HD" files and they use the ISO multiplexer, H.264 video compression and AAC audio compression.


MPEG (Moving Picture Experts Group) formats have the extension .mpg or .mpeg. MPEG files can have one or more video streams and one or more audio streams. The video streams are compressed using MPEG-2 compression scheme. The audio streams are compressed using the MPEG audio or AC3 compression scheme. Each compressed file needs a decompressor to be played or converted. This means that just because two files have the same extension they may not be similar. If you have an MPEG-2 video decoder you will be able to decode most MPEG-2 videos but since MPEG files can contains two types of audio, you may not be able to play all MPEG files unless you have both AC3 and MPEG audio decoders.


The ISO base media file format is defined in the ISO/IEC 14496-12 specification. It should not be confused with the ISO disk image used for CD and DVD images. The ISO base media file format is used in a variety of popular file  formats: MP4, 3GPP, QuickTime, Flash HD (H.264), AVC.
