Hi Frank, please allow me to introduce myself. My name is Christian and i am project administrator for an opensource project called MCF ( Multimedia Container Format ). I was posting a thread to the MPC forums at Hydrogenaudio today, but got informed from JohnV that you may not be reading there for the next 3 weeks, so he recommended to drop you an email instead. Link to the thread is here : http://www.hydrogenaudio.org/forums/showthread.php?s=&threadid=2576 . For my convenience i am simply copying and pasting what was said to the mail here : ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- ------ MCF ( Multimedia Container Format ) : offer for cooperation to the MPC dev team Hi, please allow me to repeat our offer for a cooperation to the MPC dev team here in this sector of HA ( original post in News Section ) : We were informed that current framing system of MPC ( SV7 ) does not offer any form of CRC, making streaming almost impossible. SV8 should bring a new framing for MPC, including CRC and other necessary features every modern format needs. MCF development team is of course not aware of the current status on this ( we hope our offer is not coming too late ), but we thought its better to express our commitment here to avoid unnecessary ( = double ) work, of course only if a cooperation could ever be an option for MPC dev team. Here some basic introduction to MCF : http://mcf.sourceforge.net , SF project to be found here : http://sf.net/projects/mcf . Specs are currently in the process of being updated and can change almost every minute, especially regarding transors and seek entries. For those with a compiler, you may have a look at current CVS and test recent wav2mcf ( allows creation of unvalid PCM MCF tracks ) and mpa2mcf ( same for MP3, of course also invalid files ). In short the advantages for MPC coders to consider using MCF as file format : - They can fully concentrate on improving the codec and dont need to fiddle with a container format and maintaining it. - MCF is and will be an opensource container format for all codecs ( if we manage to get them supported with specific transors ), such it is attractive for coders of editing software to implement support for it. - There are plans to adapt Virtualdub such that it will support MCF right after MCF specs and libmcf are finished and coding of a Vdub specific transor can be done. Other programs to follow. - MCF is also targeted as a container format for PCM streams, overcoming the boundaries of WAV ( 2 GB, nr. of streams, etc. ). Well renowed coders ( f.e. Naoki Shibata ) have expressed their interest in supporting MCF in their software. - libmcf was designed to be x-platform compatible right from the start ( OS specific transors do the API linking etc. with corresponding codecs, filters and applications ), also hardware support was respected in the early stages of specs definition. - MCF has extended CRC capabilities and can also be used for streaming applications. - Extensions to the MCF spec such as MCF-CD ( = XCD with specific, hardcoded support for MCF headers ) will allow to use 800 MB on 700 MB CD-Rs ( mode 2 form 2 ) We dont have any problems if the coders decide to simply use the libmcf and adapting it to support their own extension ( like .mpc ), as long as the code will be available for us. If using an external container format is not an option at all please excuse this posting here Best regards ChristianHJW ---------------------------------------------------------------------------- ---------------------------------------------------------------- This email was being copied to the MCF mailing list via gmane.org newsserver ( news://gmane.comp.video.mcf.devel ) .
