I am interested in taking a DVD, or lets say an MPEG-PS VOB file from a DVD, and splitting it up into as many separate video segment files as I can (as few fields/frames/pictures per file) without splitting interdependent pictures... essentially without losing any information.
As I am doing that, I would like to write a log of how many frames are in each segment, and what the framerate in it is, so I have a running total of the elapsed time, which I can use for synchronizing those segments with everything else. Or I guess I could wait to do the actual splitting and just write the log file along with corresponding byte offsets into the stream, and have something separate which can use the log file as an index to do splitting or extracting a set of frames based on the byte offset. I want to make sure I get all the information I need to line up all the streams in the program (video, audio, subtitles, etc), and make as precise incisions as I can without having to re-encode the video. I do expect for a select few segments I will actually split them into individual frames and have to re-encode them. As trivial as I expect this would be for somebody familiar with the low level details, I am having trouble finding a set of programs which provide it out of the box. Is something equivalent to this already available using the existing tools (like mpeg2dec), or trivial to build on libmpeg2? Or maybe there is something like the transcode tcprobe and avisplit stuff which can already do this? ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Libmpeg2-devel mailing list Libmpeg2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmpeg2-devel
