From 1710bee58ad9eecda6c27db3bb7deec9cb13c5c7 Mon Sep 17 00:00:00 2001 From: Zaheer Abbas Merali Date: Wed, 31 May 2006 10:31:23 +0000 Subject: configure.ac: Detect libiec61883 and set necessary CFLAGS and LIBS for dv1394. Original commit message from CVS: 2006-05-31 Zaheer Abbas Merali * configure.ac: Detect libiec61883 and set necessary CFLAGS and LIBS for dv1394. * ext/raw1394/Makefile.am: Add CFLAGS. * ext/raw1394/gstdv1394src.c: (gst_dv1394src_iec61883_receive), New method, to receive using libiec61883. (gst_dv1394src_iso_receive), #ifdef'd out if libiec61883 is present. (gst_dv1394src_bus_reset), Get userdata correctly if using libiec61883. (gst_dv1394src_create), When using libiec61883, only poll one fd and no need to read. (gst_dv1394src_discover_avc_node), Replace g_warnings. (gst_dv1394src_start), Create new handle when we know which dv port. More reliable than setting port on an existing handle. Initialise libiec61883. (gst_dv1394src_stop): If using libiec61883, then cleanup its handle properly. * ext/raw1394/gstdv1394src.h: Add libiec61883 handle. --- ext/raw1394/Makefile.am | 2 +- ext/raw1394/gstdv1394src.c | 153 ++++++++++++++++++++++++++++++++++++++++----- ext/raw1394/gstdv1394src.h | 6 ++ 3 files changed, 144 insertions(+), 17 deletions(-) (limited to 'ext/raw1394') diff --git a/ext/raw1394/Makefile.am b/ext/raw1394/Makefile.am index 73082d27..57749084 100644 --- a/ext/raw1394/Makefile.am +++ b/ext/raw1394/Makefile.am @@ -1,7 +1,7 @@ plugin_LTLIBRARIES = libgst1394.la libgst1394_la_SOURCES = gst1394.c gstdv1394src.c -libgst1394_la_CFLAGS = $(GST_CFLAGS) +libgst1394_la_CFLAGS = $(GST_CFLAGS) $(DV1394_CFLAGS) libgst1394_la_LIBADD = $(GST_BASE_LIBS) $(DV1394_LIBS) libgst1394_la_LDFLAGS = $(GST_PLUGIN_LDFLAGS) diff --git a/ext/raw1394/gstdv1394src.c b/ext/raw1394/gstdv1394src.c index e6289a2f..79a819f7 100644 --- a/ext/raw1394/gstdv1394src.c +++ b/ext/raw1394/gstdv1394src.c @@ -3,6 +3,7 @@ * Copyright (C) <1999> Erik Walthinsen * <2000> Daniel Fischer * <2004> Wim Taymans + * <2006> Zaheer Abbas Merali * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Library General Public @@ -34,6 +35,9 @@ #include #include #include +#ifdef HAVE_LIBIEC61883 +#include +#endif #include @@ -98,7 +102,8 @@ GST_ELEMENT_DETAILS ("Firewire (1394) DV video source", "Source/Video", "Source for DV video data from firewire port", "Erik Walthinsen \n" - "Daniel Fischer \n" "Wim Taymans "); + "Daniel Fischer \n" "Wim Taymans \n" + "Zaheer Abbas Merali "); static GstStaticPadTemplate src_factory = GST_STATIC_PAD_TEMPLATE ("src", GST_PAD_SRC, @@ -327,6 +332,70 @@ gst_dv1394src_get_property (GObject * object, guint prop_id, GValue * value, } } + +#ifdef HAVE_LIBIEC61883 +static int +gst_dv1394src_iec61883_receive (unsigned char *data, int len, + int complete, void *cbdata) +{ + GstDV1394Src *dv1394src = GST_DV1394SRC (cbdata); + + if (!GST_PAD_CAPS (GST_BASE_SRC_PAD (dv1394src))) { + GstCaps *caps; + unsigned char *p = data; + + // figure format (NTSC/PAL) + if (p[3] & 0x80) { + // PAL + dv1394src->frame_size = PAL_FRAMESIZE; + dv1394src->frame_rate = PAL_FRAMERATE; + GST_DEBUG ("PAL data"); + caps = gst_caps_new_simple ("video/x-dv", + "format", G_TYPE_STRING, "PAL", + "systemstream", G_TYPE_BOOLEAN, TRUE, NULL); + } else { + // NTSC (untested) + dv1394src->frame_size = NTSC_FRAMESIZE; + dv1394src->frame_rate = NTSC_FRAMERATE; + GST_DEBUG + ("NTSC data [untested] - please report success/failure to "); + caps = gst_caps_new_simple ("video/x-dv", + "format", G_TYPE_STRING, "NTSC", + "systemstream", G_TYPE_BOOLEAN, TRUE, NULL); + } + gst_pad_set_caps (GST_BASE_SRC_PAD (dv1394src), caps); + gst_caps_unref (caps); + } + dv1394src->frame = NULL; + if ((dv1394src->frame_sequence + 1) % (dv1394src->skip + + dv1394src->consecutive) < dv1394src->consecutive) { + if (complete && len == dv1394src->frame_size) { + gint64 i64; + guint8 *bufdata; + GstBuffer *buf; + GstFormat format; + + buf = gst_buffer_new_and_alloc (dv1394src->frame_size); + + /* fill in offset, duration, timestamp */ + GST_BUFFER_OFFSET (buf) = dv1394src->frame_sequence; + format = GST_FORMAT_TIME; + gst_dv1394src_convert (GST_BASE_SRC_PAD (dv1394src), GST_FORMAT_DEFAULT, + GST_BUFFER_OFFSET (buf), &format, &i64); + GST_BUFFER_TIMESTAMP (buf) = i64; + gst_dv1394src_convert (GST_BASE_SRC_PAD (dv1394src), GST_FORMAT_DEFAULT, + 1, &format, &i64); + GST_BUFFER_DURATION (buf) = i64; + bufdata = GST_BUFFER_DATA (buf); + memcpy (bufdata, data, len); + dv1394src->buf = buf; + } + } + dv1394src->frame_sequence++; + return 0; +} + +#else static int gst_dv1394src_iso_receive (raw1394handle_t handle, int channel, size_t len, quadlet_t * data) @@ -340,6 +409,7 @@ gst_dv1394src_iso_receive (raw1394handle_t handle, int channel, size_t len, this file in CVS. */ unsigned char *p = (unsigned char *) &data[3]; + int section_type = p[0] >> 5; /* section type is in bits 5 - 7 */ int dif_sequence = p[1] >> 4; /* dif sequence number is in bits 4 - 7 */ int dif_block = p[2]; @@ -347,7 +417,6 @@ gst_dv1394src_iso_receive (raw1394handle_t handle, int channel, size_t len, /* if we are at the beginning of a frame, we set buf=frame, and alloc a new buffer for frame */ - if (section_type == 0 && dif_sequence == 0) { // dif header if (!GST_PAD_CAPS (GST_BASE_SRC_PAD (dv1394src))) { GstCaps *caps; @@ -386,7 +455,6 @@ gst_dv1394src_iso_receive (raw1394handle_t handle, int channel, size_t len, gst_buffer_unref (dv1394src->frame); } } - dv1394src->frame = NULL; if ((dv1394src->frame_sequence + 1) % (dv1394src->skip + dv1394src->consecutive) < dv1394src->consecutive) { GstFormat format; @@ -449,7 +517,7 @@ gst_dv1394src_iso_receive (raw1394handle_t handle, int channel, size_t len, return 0; } - +#endif /* * When an ieee1394 bus reset happens, usually a device has been removed * or added.
