QuantDump Description

QuantDump is a simple, small and easy-to-use command line program that dumps the quant matrices from an MPEG2 elementary stream or program stream to a log file or to the standard output. Run QuantDump from a DOS window or by executing it programmatically from your application. Usage: quantdump infile If outfile is omitted, the output goes to the standard output, otherwise it goes to the specified file. Note that only stream events that change the active quant matrices are logged. So, for example, if you have the same matrices sent with each sequence header, only the first will be logged (because it changes the default matrices). Also note that the frame numbering refers to the encoded frame numbers and not the display frame numbers. These two are different when pulldown is present. In that case, you can use a DGIndex project with "Ignore Pulldown Flags" to serve the video such that the display frame numbers correspond to the encoded frame numbering.
