darkman Posted March 14, 2005 Posted March 14, 2005 (edited) SolveigMM MPEG2 Requantizer Component. SolveigMM MPEG2 Requantizer Component is an engine designed for a fast and quality recompression of MPEG-2 high bitrates video. The component was implemented as DirectShow filter.One of its main purposes is a fast DVD back up. The demo application inputs are MPEG-2 Video Elementary Stream, MPEG-2 Program Stream, DVD VOB files. It splits video/audio streams, recompresses MPEG-2 VES in concordance with set compression ratio (picture 1) and writes audio/video streams to respective files. Audio streams are dumped as is, without recompression. Total audio/video files size is approximate size MPEG-2 or VOB of file containing these streams after multiplexing. Such one can estimate potential VOB size decrease. http://www.solveigmm.com/?Products&p=MPEG2Requant Edited March 14, 2005 by darkman Quote
darkman Posted April 18, 2005 Author Posted April 18, 2005 The new version of SolveigMM MPEG2 Requantizer DirectShow Filter (v.1.01) has been uploaded. http://www.solveigmm.com/files/SMM_MP2Req_2005_04.06.zip The version has been impoved in terms of stability to MPEG2 VES bitstream errors. Quote
darkman Posted June 24, 2005 Author Posted June 24, 2005 New version 1.1 is available It accepts advanced parameters: - a unique compression rate for each picture type I,P,B - amount of macroblock DCT coefficients to be discarded http://www.solveigmm.com/?Products&id=MPEG2Requant Quote
Technofriend Posted June 24, 2005 Posted June 24, 2005 Did You try it built in the graph (so to say as live-recording)? How well did it work? What are the limitations (as it's only a demo)? How much is it (or is the direct show filter free)? Thanx in advance. Quote

If you need the requantizer API, you can either contact us at info(dog)solveigmm(dot)com or get the information here : http://forums.dvbowners.com/index.php?showtopic=3033 Best Regards, Dmitry Vergeles Quote
Technofriend Posted June 27, 2005 Posted June 27, 2005 Thanx for your answer and the interesting forumlink. Quote
