What is attempted is based on the -state of the parser (gee, so that's why they call it a state machine ). -The stages are: - -1) looking for sync (have_sync == FALSE) - a) have some zeros (zeros > 0) -2) getting ID (have_sync == TRUE, id == 0) -3) decoding the chunk contents (have_sync == TRUE, id != 0) - -Mechanism for handling cross-buffer chunks of data -================================================== - -The problem: if data were to come to the parser in 64-byte chunks, the -pack head would be split across at least two buffers, possibly three. Up -front I will make the assumption that no one will be sending buffers of -less size than the largest chunk (header, PES packet), such that no chunk -will be split across more than two buffers. - -If we take the pack header as an example, when the stream starts out, we -can assume that the it starts at the beginning of the buffer and doesn't -exceed the bounds of it. However, if we're mid-stream and starting -another pack, it can be split across two buffers. diff --git a/win32/MANIFEST b/win32/MANIFEST index 8e37b135d3..42c53a19a3 100644 --- a/win32/MANIFEST +++ b/win32/MANIFEST @@ -1,13 +1,10 @@ win32/MANIFEST win32/common/config.h win32/vs6/gst_plugins_ugly.dsw -win32/vs6/libgstac3parse.dsp win32/vs6/libgstasfdemux.dsp win32/vs6/libgstdvdlpcmdec.dsp win32/vs6/libgstdvdsub.dsp win32/vs6/libgstlame.dsp win32/vs6/libgstmad.dsp -win32/vs6/libgstmpegaudioparse.dsp -win32/vs6/libgstmpegstream.dsp win32/vs6/libgstrealmedia.dsp win32/vs6/libgstsynaesthesia.dsp diff --git a/win32/vs6/gst_plugins_ugly.dsw b/win32/vs6/gst_plugins_ugly.dsw index ee6e9cce78..32d2fd3a86 100644 --- a/win32/vs6/gst_plugins_ugly.dsw +++ b/win32/vs6/gst_plugins_ugly.dsw @@ -3,18 +3,6 @@ Microsoft Developer Studio Workspace File, Format Version 6.00 ############################################################################### -Project: "libgstac3parse"=".\libgstac3parse.dsp" - Package Owner=<4> - -Package=<5> -{{{ -}}} - -Package=<4> -{{{ -}}} - -############################################################################### - Project: "libgstasfdemux"=".\libgstasfdemux.dsp" - Package Owner=<4> Package=<5> @@ -51,18 +39,6 @@ Package=<4> ############################################################################### -Project: "libgstiec958"=".\libgstiec958.dsp" - Package Owner=<4> - -Package=<5> -{{{ -}}} - -Package=<4> -{{{ -}}} - -############################################################################### - Project: "libgstlame"=".\libgstlame.dsp" - Package Owner=<4> Package=<5> @@ -87,30 +63,6 @@ Package=<4> ############################################################################### -Project: "libgstmpegaudioparse"=".\libgstmpegaudioparse.dsp" - Package Owner=<4> - -Package=<5> -{{{ -}}} - -Package=<4> -{{{ -}}} - -############################################################################### - -Project: "libgstmpegstream"=".\libgstmpegstream.dsp" - Package Owner=<4> - -Package=<5> -{{{ -}}} - -Package=<4> -{{{ -}}} - -############################################################################### - Project: "libgstrealmedia"=".\libgstrealmedia.dsp" - Package Owner=<4> Package=<5> diff --git a/win32/vs6/libgstac3parse.dsp b/win32/vs6/libgstac3parse.dsp deleted file mode 100644 index e89aa9325f..0000000000 --- a/win32/vs6/libgstac3parse.dsp +++ /dev/null @@ -1,123 +0,0 @@ -# Microsoft Developer Studio Project File - Name="libgstac3parse" - Package Owner=<4> -# Microsoft Developer Studio Generated Build File, Format Version 6.00 -# ** DO NOT EDIT ** - -# TARGTYPE "Win32 (x86) Dynamic-Link Library" 0x0102 - -CFG=libgstac3parse - Win32 Debug -!MESSAGE This is not a valid makefile.
