Free mjpeg software for linux

The mjpeg programs are a set of tools that can do recording of videos and playback, simple cut-and-paste editing and the MPEG compression of audio and video under Linux.
Recording is supported for the Zoran based cards like the Buz (Iomega), DC10 (MIRO, Pinnacle), Matrox Marvel cards and the LML33 (Linux Media Labs). See related pages to the right to find the right driver for your card.
The recorded videos can be converted to MPEG streams. The software playback of MPEG streams works with almost every player and every OS.
You can produce special forms of MPEG streams like VCD (Video CD) and SVCD for hardware playback.
A key design objective of the tools is interoperability with other video tools:
The tools can be used used to edit, playback and compress motion JPEG (MJPEG) AVIs captured using the xawtv package.
The tools can be used to edit playback and compress MJPEG streams created and editted with broadcast 2000. N.b. the current mpeg2movie high bit-rate MPEG encoder is in large part derived from an obsolescent snapshot of the mjpegtools MPEG encoder.
Enhancements:
- changes in YUV4MPEG2 API to offer support for multiple colorspaces (particularly useful for DV video), so that multiple planar YUV formats (also monochrome or alpha) are supported.
- most filtering tools have been adapted to support multiple YUV formats, so that you will not lose quality/precision in conversion steps.
- Many new or dramatically improved filters including (but not limited to):
*) yuvdenoise (denoising filter)
*) yuvdeinterlace (intelligent deinterlacing program)
*) y4munsharp (unsharp mask image sharpening program)
- Improvements in the IDCT/DCT routines in the MPEG-1/-2 encoder (much more exact now and not subject to overflow/truncation on the IA32 arch).
- MANY new utilties for importing/exporting data:
*) New and improved PGM/PNM conversion programs for dealing with PPM data.
*) Utilities to convert raw (headerless) YUV data to and from YUV4MPEG2 format. Useful when interfacing with other program suites.
*) Program (yuyvtoy4m) to convert 4:2:2 data from digital cameras into YUV4MPEG2 format for use with mjpegtools.
*) y4mstabilizer for stabilizing images with unsteady camera work
- Improvements and fixes in mplex for handling PCM audio (LPCM audio actually works now)
- DPME (Dual Prime Motion Estimation) in the encoder (mpeg2enc) is fully functional (it was present but buggy/artifacted in the earlier releases)
- Rate control in the encoder improved considerably.
- Much better Quicktime file handling (via libquicktime) especially the audio tracks.
- Besides the always-excellent x86 support, we now have full support for AMD64 (including MMX/SSE/etc. optimizations) and for PPC (e.g. Linux or OS/X), and win32 support is also available (via Cygwin/Mingw).

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.

KWiideo is a video encoder for the mjpeg codec, which is supported by the Nintendo Wii.

You can use mencoder or ffmpeg as encoder. If you want to add subtitles you have to use mencoder, because ffmpeg cant add srt files to videos (maybe ffmpeg can do it, but didnt found a function for it).

You can set the quality of the output video using the quality slider. Available values 1 (best quality, largest files) to 30 (poor quality, small files). An other way to change the quality is setting the bitrate. High bitrates create better quality, but the filesize increase. It is not possible to use the quality slider and the bitrate setting function at the same time. Changing the bitrate seems not to work with mencoder and mjpeg as codec, you better take the quality slider when you use mencoder as encoder.

For splitting the video, you need avisplit. Comments are welcome.

MythTV project is a suite of programs that allow you to build the mythical home media convergence box on your own using Open Source software and operating systems.
MythTV is a project aiming to create a homebrew set-top box. The end goal is to have a nice interface for watching TV, recording shows, listening to music, etc., all displayed on a TV and controlled by a remote.
Main features:
- Basic live-tv functionality. Pause/Fast Forward/Rewind "live" TV.
- Support for multiple tuner cards and multiple simultaneous recordings.
- Distributed architecture allowing multiple recording machines and multiple playback machines on the same network, completely transparent to the user.
- Compresses video in software using rtjpeg (from Nuppelvideo) or mpeg4 (from libavcodec). Full support for Hardware MPEG-2 encoder cards (Hauppauge PVR-250 / PVR-350). Preliminary support for DVB cards and the new pcHDTV tuner card.
- Support for the (very nice looking) hardware MPEG-2 decoder and TV out present on the Hauppauge PVR-350.
- Completely automatic commercial detection/skipping
- Grabs program information using xmltv.
- A fully themeable menu to tie it all together.
The television portion allows you to do the following:
- You may pause, fast-forward and rewind live Television.
- You may install multiple video capture cards to record more than one program at a time.
- You can have multiple servers, each with multiple capture cards in them. All servers are centrally managed and all programs are scheduled by the Master backend.
- You can have multiple clients (called "frontends" in MythTV parlance), each with a common view of all available programs. Any client can watch any program that was recorded by any of the servers. Clients can be diskless and controlled entirely by a remote control.
- You may use any combination of standard analog capture card, MPEG-2, MJPEG, DVB or HDTV capture devices. With appropriate hardware, MythTV can control set top boxes, often found in digital cable and satellite TV systems.
- Program Guide Data in North America is downloaded from Zap2It.com, a subsidiary of Tribune Media Services. This free service is called DataDirect, and provides MythTV almost two weeks of scheduling information. Program Guide Data in other countries is obtained using XMLTV. MythTV uses this information to create a schedule that maximizes the number of programs that can be recorded if you dont have enough tuners.
Other modules in MythTV include:
- MythGallery, a picture-viewing application
- MythVideo, a media-viewer for content not created within MythTV
- MythDVD, a DVD viewer / ripper
- MythMusic, a music playing / ripping application which supports MP3 and FLAC
- MythGame
- MythWeather
- MythNews, a RSS news grabber
- MythBrowser, a web browser
- MythWeb, which allows you to control your MythTV system using a web browser. With MythWeb, you can schedule recordings, delete files, change keybindings and more. With proper security, you may even schedule a program over the Internet and have it immediately acted on by the scheduler.
- MythPhone, phone and videophone using SIP.
