Packaging Multimedia Content

GPAC features encoders and multiplexers, publishing and content distribution tools for MP4 and 3GPP(2) files and many tools for scene descriptions (BIFS/VRML/X3D converters, SWF/BIFS, SVG/BIFS, etc...). MP4Box provides all these tools in a single command-line application. An exhaustive list of packaging features is available here but a good summary of what MP4Box can do for you is the following:

• MP4/3GP Conversion from MP3, AVI, MEPG-2 TS, MPEG-PS, AAC, H263, H264, AMR, and many others,
• File layout: fragmentation or interleaving, and cleaning,
• File hinting for RTP/RTSP and QTSS/DSS servers (MPEG-4 / ISMA / 3GP / 3GP2 files),
• File splitting by size or time, extraction from file and file concatenation,
• XML information dumping for MP4 and RTP hint tracks,
• Media Track extractions,
• ISMA E&A encryption and decryption,
• 3GPP timed text tools (SUB/SRT/TTXT/TeXML), VobSub import/export,
• BIFS codec and scene conversion between MP4, BT and XMT-A,
• LASeR codec and scene conversion between MP4, SAF, SVG and XSR (XML LASeR),
• XML scene statistics for BIFS scene (BT, XMT-A and MP4),
• Conversion to and from BT, XMT-A, WRL, X3D and X3DV with support for gzip.

Playing Multimedia Content

GPAC supports many protocols and standards, among which:

• BIFS scenes (2D, 3D and mixed 2D/3D scenes),
• VRML 2.0 (VRML97) scenes (without GEO or NURBS extensions),
• X3D scenes (not complete) in X3D (XML) and X3DV (VRML) formats,
• SVG Tiny 1.2 scenes,
• LASeR and SAF (partial) support,
• Progressive loading/rendering of SVG, X3D and XMT files,
• HTTP reading of all scene descriptions,
• GZIP supported for all textual formats of MPEG4/X3D/VRML/SVG,
• MP4 and 3GPP file reading (local & http),
• MP3 and AAC files (local & http) and HTTP streaming (ShoutCast/ICECast radios),
• Most common media codecs for image, audio and video,
• Most common media containers,
• 3GPP Timed Text / MPEG-4 Streaming Text,
• MPEG-2 TS demuxer (local/UDP/RTP) with DVB support (Linux only),
• Streaming support through RTP/RTCP (unicast and multicast) and RTSP/SDP,
• Plugins for Mozilla (Win32 and Linux) and Internet EXplorer (Win32 and PPC 2003).

Streaming Multimedia Content

As of version 0.4.4, GPAC has some experimental server-side tools:

• MP4/3GP file RTP streamer (unicast and multicast),
• RTP streamer with service timeslicing (DVB-H) simulation,
• MPEG-2 TS broadcaster using MP4/3GP files or RTP streams as inputs,
• BIFS RTP broadcaster tool performing live encoding and RandomAccessPoints generation.
