Hello TSL List, This has nothing to do with TSL (well, the project is running on a TSL2.2 box, but that's about it :), but I still give it a try :
For an university project I'm working on some kind of distributed transcoding environment using the BOINC framework. The final result should be some thing that lets someone upload a mpeg2 movie (only video for the time being) and returns a mpeg1 file some time afterwards... But off course I'm running into troubles: the original dvd's vob file is demultiplexed into a mpeg2 video stream, which then is splitted using the mpgtx program (http://mpgtx.sourceforge.net/). I'm splitting the mpeg2 file into 5MB chunk, but since the mpgtx file works on a GOP (group of pictures) basis their size varies between 5 and 6MB. Once they're splitted I feed them to BOINC that distributes them to the various nodes. These nodes return the result of a "ffmpeg -target pal-vcd". After that I rejoin the results using the same mpgtx program, but there the problem begins.. for some reason the end result isn't a fluent movie, but something that has a repeating gop (?) in it at each joining-point. Tried to remove the first gop from all result files when rejoining, which solves the problem for some parts of the movie, but not all. So, the short question: is there anyone who knows how to split a mpeg file, transcode the different chunks and merge them in a fluent movie stream? Many thanks in advance, Kim _______________________________________________ tsl-discuss mailing list [email protected] http://lists.trustix.org/mailman/listinfo/tsl-discuss
