Free mpeg2 software for windows

The MPEG2Cut application was designed to be a fast and easy to use MPEG2 video cutter. It will help you cut a video part from the MPEG2 file.

Enhancements:
- added experimental VOB support (was possible in previous version also)
- added experimental MPEG2 VIDEO only cutting support
- added ac3 playback
- added track selectioning while playback
- cutting: made i/o buffer bigger to hopefully speed up things
- now 0 and insert will also start/stop playback mode
- (so I can switch between ff/fb and play without moving my hand too much...)
- some tidbits here and there
- finally released source and taking some rest now.

The name MPEG2 TS Packet Analyser stands for MPEG-2 Transport Stream Packet Analyser.
MPEG-2 Transport Stream Packet Analyser was designed to enable decoding and low level analysis of DVB MPEG-2 transport streams. It can be used for fault-finding, equipment and system testing, software development and learning more about how MPEG-2 systems work.
Main features:
View
- Open MPEG-2 transport stream files (188 byte packets)
- Navigate through the stream, filter on PID and/or payload start flag
- View Transport Stream headers
- View Packetized Elementary stream headers and stream types
- View MPEG-2 and DVB table headers; PAT, PMT, NIT, BAT, SDT, EIT, TDT, TOT
- View MPEG-2 video sequence headers; picture size, aspect ratio and frame rate
- View Active Format Descriptors (AFD) as defined by the DTG D-Book
- Decode PAT, program numbers and program map PIDs
- Decode TDT, current date and time
- Check TS packet continuity count compliance on a single PID or the entire stream
- Full decoding of table descriptors will be added in the next release
Output
- De-multiplex the stream to remove unwanted PIDs of null packets
- Generate a PID usage report and save as a CSV file
- Save TS headers as a CSV file
Open, decode and de-mux MPEG-2 transport streams from digital satellite, cable and terrestrial TV broadcasts.
System requirements:
- .NET Framework 2.0

Enhancements:
- Added new transport stream continuity counter checking feature.
- Made provision for files that do not start with a sync byte, offsets will be detected.
- Improved checking routine when opening a file.
- Added dialogue box for TS header export, user can choose start packet, end packet and enable pid or payload start filters.
- Enhanced payload start filter on main window, it is now possible to filter on 0 and 1.
- Minro improvements to PES and AFD viewer
- Added table_id decoding to main dialogue

The widely used tools DVD2AVI and MPEG2DEC suffer from a fundamental deficiency: they do not deliver all the coded frames from the input stream. Put simply, they lose frames.
This can cause serious problems with audio sync and authoring with some tools. Not only that, but random frame access is not handled correctly and incorrect frames can be returned when navigating on the timeline via MPEG2DEC (and its clones).
Additionally, the original DVD2AVI project was not updated in some time, and it stood in need of some fixes and upgrades. My version addresses a lot of the irritating features of the original project, as well as adds many new and useful features.
Notable is support for MPEG1, PVA, and transport streams.
There are three causes for the frame loss in the faulty versions.
1. DVD2AVI fails to flush out the final frames digit to the D2V file before writing the 9 and closing. This causes one frame to to be lost at the end.
2. MPEG2DEC cuts two frames from the frame count as a workaround for 3 below. This is a kludgy hack that should not be necessary. Thus, thanks to this and 1 above, 3 frames will always be lost. They are lost at the end.
3. If the opening GOP has B frames before the first P frame (IBBPBBP...), then DVD2AVI generates an incorrect D2V file, in which the first digits for the orphaned B frames and some remaining digits are written out of place. Also, MPEG2DEC cannot decode the B frames prior to the first P frame, and so discards them. A number of frames will be lost equal to the number of B frames prior to the first P frame. They are lost at the beginning.
So, for example, if you process a VOB that has an IBBPBBP... opening GOP, you will lose a total of 5 frames, with 2 lost at the start and 3 lost at the end.
In addition to the lost frames, MPEG2DEC does not implement random frame access correctly. In fact, it always throws away the first B frames in the GOP prior to the first P frame. If they are (say) frames 12 and 13 (in display order) and you try to seek to 12, MPEG2DEC will toss them and return frame 14 to you, without any warning or indication about it.
Finally, when 3 above applies the TFF/RFF flags in the D2V file are misaligned to the frames.
I have created fixed versions of DVD2AVI and MPEG2DEC3 that solve these problems, as well as provide a lot of very useful new features. To avoid confusion, these are renamed as DGIndex and DGDecode respectively.
I engineered DGIndex to create fully correct D2V files containing all the input frames. I engineered DGDecode to not truncate B frames prior to the first P frame and to not unconditionally reduce the frame count by two. I rewrote the decoding and random access code to work correctly with the D2V files generated by the fixed DGIndex.
For DGIndex, if your input stream starts with an open GOP, a message box will pop up warning you that the first few frames may not be decoded properly, but the frames will be retained (they are output as copies of the first decodable frame so as not to output corrupted frames). To avoid this problem, always cut your VOBs on cell boundaries. Do not make arbitrary VOB cuts with a binary splitter (such as VOBSplit).

Enhancements:
- Version 1.5.1 is a patch release that fixes a problem with stream detection.

The PVACut software was designed to help you cut the native .pva / .pav to mpeg2 file format of some DVB Video cards.
Main features:
- Cut the files at the I-frames border. (No quality loss, but 1-2 defective Frames at cut bordes)
- Version with and without Video display.
- Possible to cut 2 or more files into one file.
System requirements:
- DVB-S card installed
NOTE:
- Free for non comercial use

Enhancements:
- bugfix for fast scan on Win NT Systems
