Otra Nueva Posibilidad (Tiliin)

Otra nueva plataforma que posibilita o facilita lo que se quiere hacer con Tiliin (Videotraking), esta también en ingles pero es muy interesantes.

Multiplatform

GStreamer has been ported to a wide range of operating systems, processors and compilers. These include but are not limited to Linux on x86, PPC and ARM using GCC. Solaris on x86 and SPARC using both GCC and Forte, MacOSX, Microsoft Windows using MS Visual Developer, IBM OS/400 and Symbian OS.
GStreamer can bridge to other multimedia frameworks in order to reuse existing components (e.g. codecs) and use platform input/output mechanisms:
  • Linux/Unix: OpenMAX-IL (via gst-openmax)
  • Windows: DirectShow
  • MaxOS X: QuickTime



Comprehensive Core Library

  • Graph-based structure allows arbitrary pipeline construction
  • Based on GLib 2.0 object model for object-oriented design and inheritance
  • Compact core library of less than 500KB, about 65 K lines of code
  • Multi-threaded pipelines are trivial and transparent to construct
  • Clean, simple and stable API for both plugin and application developers
  • Extremely lightweight data passing means very high performance/low latency
  • Complete debugging system for both core and plugin/app developers
  • Clocking to ensure global inter-stream synchronization (a/v sync)
  • Quality of service (qos) to ensure best possible quality under high CPU load

Intelligent Plugin Architecture

  • Dynamically loaded plugins provide elements and media types, demand-loaded via a registry cache, similar to ld.so.cache
  • Element interface handles all known types of sources, filters and sinks
  • Capabilities system allows verification of element compatibility using MIME types and media-specific properties
  • Autoplugging uses capabilities system to complete complex paths automatically
  • Pipelines can be saved to XML and loaded back to working state
  • Resource friendly plugins don't waste memory

Broad Coverage of Multimedia Technologies

GStreamers capabilities can be extended through new plugins. The features listed below are just a rough overview what is available using the GStreamers own plugins, not counting any 3rd party offerings.
  • container formats: asf, avi, 3gp/mp4/mov, flv, mpeg-ps/ts, mkv, mxf, ogg
  • streaming: http, mms, rtsp
  • codecs: FFmpeg, various codec libraries, 3rd party codec packs
  • metadata: native container formats with a common mapping between them
  • video: various colorspaces, support for progressive and interlaced video
  • audio: integer and float audio in various bit depths and multichannel configurations
