FFmpeg::Stream is an audio or video stream from a (multi)media file.

SYNOPSIS

$ff = FFmpeg->new(); #see FFmpeg
#...
$sg = $ff->create_streamgroup(); #see FFmpeg
$st = ($sg->streams())[0]; #this is a FFmpeg::Stream

FFmpeg::Stream objects are not instantiated. Rather, objects are instantiated from FFmpeg::Streams subclasses FFmpeg::Stream::Video for video streams, FFmpeg::Stream::Audio for audio streams, and FFmpeg::Stream::Data for streams containing neither audio nor video data. Streams identified in the file whose content type cannot be determined are represented by FFmpeg::Stream::Unknown objects.

Access FFmpeg::Stream objects using methods in FFmpeg::StreamGroup. See FFmpeg::StreamGroup for more information.

This class has attributes applicable to any stream type in a multimedia stream, or stream group. FFmpeg-Perl represents multimedia stream group information in a FFmpeg::StreamGroup object, which is a composite of FFmpeg::Stream objects.

FFmpeg::Stream objects dont do much. They just keep track of the media streams ID within the multimedia stream group, and hold an instance to a FFmpeg::Codec object if the codec of the stream was deducible. See FFmpeg::Codec for more information about how codecs are represented.

FFmpeg::StreamGroup is a group of related media streams, typically encapsulated in a single file.

SYNOPSIS

$ff = FFmpeg->new() #see FFmpeg;
#...
$sg = $ff->build_streamgroup();

Objects of this class are not intended to be instantiated directly by the end user. Access FFmpeg::StreamGroup objects using methods in FFmpeg. Refer to FFmpeg for more information.

This is a composite class of FFmpeg::Stream objects. A StreamGroup in most cases maps directly to a file, but it is also possible that it can represent data coming over a socket (eg HTTP), filehandle (eg STDIN), or a peripheral device (eg a TV tuner card).
A media stream, represented by the FFmpeg::Stream class is never created without a parent stream group. Metadata that may be attached to a stream is always attached to the group which contains the stream.

An example of this is an MP3 file which has been ID3 "tagged". Metadata regarding the MP3 audio data in the file, such as year of recording, artist name, album name, and genre are attached to a FFmpeg::StreamGroup rather than onto the FFmpeg::Stream object representing the audio data itself.

The FFmpeg::StreamGroup object is useful not only for retrieving stream group metadata, but also for inspecting the component streams of the group. See "streams()" for details.

This class also has rudimentary support for transcoding, in the form of a "frame grab". See "capture_frame()" for details.

FFmpeg::Stream::Audio is an audio stream from a (multi)media stream group.

SYNOPSIS

$ff = FFmpeg->new(); #see FFmpeg
#...
$sg = $ff->create_streamgroup(); #see FFmpeg
$st = ($sg->streams())[0]; #this is a FFmpeg::Stream

Objects of this class are not intended to be instantiated directly by the end user. Access FFmpeg::Stream::Audio objects using methods in FFmpeg::StreamGroup. See FFmpeg::StreamGroup for more information.

This class represents an audio stream in a multimedia stream group, and has audio-specific attributes. General stream attributes can be found in the FFmpeg::Stream class.

GStreamer FFmpeg plug-in contains one plugin with a set of elements that use the FFmpeg library code. It contains most popular decoders as well as very fast colorspace conversion elements.
GStreamer is a library that allows the construction of graphs of media-handling components, ranging from simple Ogg/Vorbis playback to complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.
GStreamer is released under the LGPL.
Main features:
Multiplatform
- GStreamer has been ported to a wide range of operating systems, processors and compilers. This include but are not limited to Linux on i86,PPC, ARM using GCC. Solaris on x86 and SPARC using both GCC and Forte, MacOSX, Microsoft Windows using MS Visual Developer and IBM OS/400.
Comprehensive Core Library
- Graph-based structure allows arbitrary pipeline construction
- Based on GLib 2.0 object model for object-oriented design and inheritance
- Small core library of less than 150KB, about 10 K lines of code
- Pluggable scheduling system capable of dealing with most pipeline structures
- Multi-threaded pipelines are trivial and transparent to construct
- Clean and simple 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
Intelligent Plugin Architecture
- Dynamically loaded plugins provide elements and media types, demand-loaded via an XML registry, similar to ld.so.cache
- Element interface handles all known types of sources, filters, 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 dont waste RAM
Extensive Development Tools
- Graphical editor allows pipelines to be built quickly, run, and saved as XML
- gst-launch command-line tool enables even quicker prototyping and testing, similar to ecasound
- All tools written as libraries to allow easy reuse
- A lot of documentation, including partially completed manual and plugin writers guide
- Large selection of test programs and example code
- Access to GStreamer API with various programming language

Libmpeg3 supports advanced editing and manipulation of MPEG streams. MPEG is normally a last mile distribution format but with libmpeg3 you can edit it like a production format. Unless you have a need for MPEG editing and copying, youre better off using a consumer library like FFMPEG.
Libmpeg3 is primarily a supporting library for Cinelerra. It supports all of the nonstandard operations Cinelerra needs. Libmpeg3 provides a uniform front end for a large number of the MPEG formats used in HDTV broadcasting. It decodes:
- MPEG-1 Layer II Audio
- MPEG-1 Layer III Audio
- MPEG-2 Layer III Audio
- MPEG-1 program streams
- MPEG-2 program streams
- MPEG-2 transport streams
- AC3 Audio
- MPEG-2 Video
- MPEG-1 Video
- IFO files
- VOB files
Now the good news. It can read the MPEG exports from Cinelerra.
A table of contents feature allows it to seek with frame accuracy regardless of whether the footage has timecode or not, or whether the timecode is contiguous. Also included are utilities for stream extraction, format querying, and copying.
Enhancements:
- Table of contents sample count improvements.
- Migration to GCC 4.1.

MPEG4IP provides an end-to-end system to explore streaming multimedia. The package includes many existing open source packages and the "glue" to integrate them together. This is a tool for streaming video and audio that is standards-oriented and free from proprietary protocols and extensions.

Provided are a live MPEG-4/H.261/MPEG-2/H.263 MP3/AAC/AMR broadcaster and file recorder, command line utilities such as an MP4 file creator and hinter, and an player that can both stream and playback from local file.

Our development is focused on the Linux platform, and has been ported to Windows, Solaris, FreeBSD, BSD/OS and Mac OS X, but it should be relatively straight-forward to use on other platforms. Many of the included packages are multi-platform already. Mp4live only works on Linux.

This code is not intended for end users, and does not contain executables. Please read all the legal information to determine if it is suitable for you.

MplayerXP is a branch of the well known mplayer (http://mplayerhq.hu) which is based on the new (thread based) core. MplayerXP project was designed for x86 architecture but was ported on DecAlpha, SUN, PowerPC.
The new core provides better CPU utilization and excellently improves performance of video decoding. Main goal of this project is to get monotonous CPU loading during movie playback.
This project is a media player for *nix systems. It was designed for Linux, but works on other unices like: FreeBSD, QNX.
MplayerXP project was designed for x86 architecture but was ported on DecAlpha, SUN, PowerPC.
Enhancements:
- synchronized libloader with mplayerhq
- updated ffmpeg codecs (fixes some lacks of prev release)
- added support for new codecs
- fixed segfault in MPC demuxer
