From d1f62e8a4f976e11634d2f9187821e8686cec76d Mon Sep 17 00:00:00 2001 From: David Schleef Date: Sun, 27 Jul 2003 05:24:15 +0000 Subject: Moved to gst-libs/ext/mplex Original commit message from CVS: Moved to gst-libs/ext/mplex --- ext/mplex/INSTRUCT | 67 ------------------------------------------------------ 1 file changed, 67 deletions(-) delete mode 100644 ext/mplex/INSTRUCT (limited to 'ext/mplex/INSTRUCT') diff --git a/ext/mplex/INSTRUCT b/ext/mplex/INSTRUCT deleted file mode 100644 index e75d4cfa..00000000 --- a/ext/mplex/INSTRUCT +++ /dev/null @@ -1,67 +0,0 @@ -////////////////////////////////////////////////////////////////////////// -// // -// INSTRUCTIONS FOR MPLEX - THE MPEG1/SYSTEMS MULTIPLEXER // -// // -////////////////////////////////////////////////////////////////////////// - - -Please note that I do not have a comprehensive instruction manual for this -release.

Say you -have a 40 kByte video buffer and a 2324 Byte Sector size, then -a startup delay of 8 sectors will work just fine. - -What does the above parameter mean? - -Normally, the Decoding/Presentation Time Stamp of the first access -unit is set to the clock value that will happen exactly after the last -packet containig data from this first unit arrives into the system -target decoder. This works fine if the video/audio streams are of -*very perfectly constant* or the packet size are *very* small -(ideally: the size of one access unit, that would mean variable -packet length). -Anyway: this parameter allows you to say that the System Target -Decoder should start decoding the first access unit after he -gets (startup_packet_delay + size_of_first_access_units[av]) -packets of data. -This guarantees that the buffers are conveniently filled up. -Note that both the video stream offset and audio stream offset (ms) -add up even more bytes to this startup delay, but you can -tell conveniently that audio should start so many ms after video, -for example. - -Sorry for no further doc, enjoy multiplexing A/V :) - -Christoph. - -moar@heaven.zfe.siemens.de -+---------------------------------------+--------------------------------+ -| http://www.informatik.tu-muenchen.de/ | Christoph Moar | -| cgi-bin/nph-gateway/hphalle6/~moar/ | Kaulbachstr.29a | -| index.html | 80539 Munich | -| email:moar@informatik.tu-muenchen.de | voice: ++49 - 89 - 23862874 | -+---------------------------------------+--------------------------------+ - -- cgit v1.2.1
