The goal of GstValidate is to be able to detect when elements are not behaving as expected and report it to the user so he knows how things are supposed to work inside a GstPipeline. In the end, fixing issues found by the tool will ensure that all elements behave all together in the expected way. The easiest way of using GstValidate is to use one of its command-line tools, located at tools/ directory. It is also possible to monitor GstPipelines from any application by using the LD_PRELOAD gstvalidate lib. The third way of using it is to write your own application that links and uses libgstvalidate.

[ excerpt from developer's www site ] If you want to convert DVD subtitles into text format (e.g. subrip format) or VobSub format this program could be useful for you. However, it is only one tiny tool that you need in the process of producing srt files. This software depends heavily on transcode for its input and is therefore part of the transcode package (see transcode's contrib directory). So, if you want to convert some subtitles, grap a copy of the lates transcode distribution. For srt file production the output of this program should be processed by some OCR software. Currently, I work with GOCR for this purpose. For VobSub output no other tools are required.

libdvbpsi is a set of tools which allows to decode and generate all the Program specific Information (PSI) present in a MPEG2 TS or a DVB stream. The two keywords are portability and simplicity. Currently supported tables - Program Association Table (PAT, MPEG2) - Program Map Table (PMT, MPEG2)

libfame is a video encoding library. It can currently encode MPEG-1 and MPEG-4 rectangular video, as well as MPEG-4 video with arbitrary shape. Objectives - Compliance : Provide bitstreams compliant to the MPEG-1, MPEG-2 and MPEG-4 video standards. - Speed : Provide a fast implementation of the techniques used in MPEG standards. - Flexibility : Allow the user to choose between different options for speed, compression ratio and quality. - Portability : Support many different platforms and architectures.

libdc1394 is a library that provides a complete high level application programming interface (API) for developers who wish to control IEEE 1394 based cameras that conform to the 1394-based Digital Camera Specifications (also known as the IIDC or DCAM Specifications).

[ excerpt from developer's site ] It is a free library for decoding mpeg-2 and mpeg-1 video streams. The main goals in libmpeg2 development are: Conformance - libmpeg2 is able to decode all mpeg streams that conform to certain restrictions: "constrained parameters" for mpeg-1, and "main profile" for mpeg-2. In practice, this is what most people are using. For streams that follow these restrictions, we believe libmpeg2 is 100% conformant to the mpeg standards - and we have a pretty extensive test suite to check this. Speed - for most current systems, the display will actually take more time than the mpeg-2 decoding. For systems that have hardware color conversion and scaling (as we can use with the xv extension in Xfree 4), you should be able to watch DVD streams on a Celeron 400. On a PIII/666 with null display you should get about 110 frames per second. Portability - most of the code is written in C, and when we use platform-specific optimizations we always have a generic C routine to fall back on.

Livestreamer is a Command Line Interface that pipes video streams from various services into a video player, such as VLC. The main purpose of Livestreamer is to allow the user to avoid buggy and CPU heavy flash plugins but still be able to enjoy various streamed content. Livestreamer is built upon a plugin system which allows support for new services to be easily added. Currently most of the big streaming services are supported, such as: Dailymotion Livestream Twitch/Justin.tv YouTube Live UStream Example use: $ livestreamer twitch.tv/day9tv best [cli][info] Found matching plugin justintv for URL twitch.tv/day9tv [cli][info] Opening stream: 720p [cli][info] Starting player: vlc

dvdrip is a Command Line Tool to make a copy from a Video DVD for private Use. It automates the process of Ripping, Authoring, Preview and Burning of a DVD. Features: - Automatic Selection of the longest Title - Automatic Calculation of Factor to Requant - Automatic Read of Volume-ID - Automatic Chapter Separation from Original - Ripping of Audiotracks in every Language - Selection of dts-Audiotracks as Default - Selection of two Subpicture-Tracks possible - Ripping and Re-Authoring - Preview of VOB-Files with mplayer or xine - Burning with growisofs or cdrecord-prodvd - All Program Parameters could be stored in a Config File as Program Defaults - All Paramaters can be overwritten on the fly at the Command Line - Program with english, french or german Messages - Rip of Subpicture-Tracks - Copy DVD < 4.7 GB with Menus; > 4.7 GB with vamps, without Menus. - Partial Copy: Copy selected Titles from a DVD (dvdunauthor/vamps) - High Quality Backup (1 DVD9 => 2 DVD5) - DVD with Menus for Title-, Audio- and Chapter Selection (dvdwizard)

lavtools: Linux Audio and Video TOOLS for Motion JPEG and MPEG ============================================================== Programs for MJPEG recording and playback and simple cut-and-paste editting and MPEG compression of audio and video under Linux (Now FreeBSD). N.b. Only the "lav" programs have been written whooly from scratch. The rest are from diverse open source originals, modified to work with the lav tools edit lists and AVI and quicktime files. Some (especially the MPEG tools) have had also more major perfomance and functionality enhancements.

mpgtx was designed with the good old Unix philosophy in mind : do few but do it well and provide end user an austary yet powerfull command line interface. - mpgtx can currently split and join MPEG 1 video files and most MPEG audio files. - mpgtx can fetch detailed informations from MPEG 1 and MPEG 2. - mpgtx can demultiplex MPEG 1 and MPEG 2 files (System layer, Program layer and Transport Layer). - mpgtx can add, remove and edit ID3 tags from mp3 files and rename mp3 files according to their ID3 tags. - DivX ;) is not yet supported, neither is MPEG 4 - splitting and joining of MPEG 2 video files is experimental.
