Original commit message from CVS: New mimetypes gone into effect today - this commit changes all old mimetypes over to the new mimetypes spec as described in the previous commit's document. Note: some plugins will break, some pipelines will break, expect HEAD to be broken or at least not 100% working for a few days, but don't forget to report bugs --- gst-libs/gst/video/video.c | 72 +++++++++++++--------- gst-libs/gst/video/video.h | 150 ++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 192 insertions(+), 30 deletions(-) (limited to 'gst-libs/gst/video') diff --git a/gst-libs/gst/video/video.c b/gst-libs/gst/video/video.c index 6eba0d7b..11e26c96 100644 --- a/gst-libs/gst/video/video.c +++ b/gst-libs/gst/video/video.c @@ -20,31 +20,36 @@ #include "video.h" -#define NUM_UNITS 1000000000 - /* This is simply a convenience function, nothing more or less */ -gdouble +gfloat gst_video_frame_rate (GstPad *pad) { - GstFormat dest_format = GST_FORMAT_DEFAULT; - gint64 dest_value = 0; - gdouble fps; - - /* do a convert request on the source pad */ - if (!gst_pad_convert(pad, - GST_FORMAT_TIME, GST_SECOND * NUM_UNITS, - &dest_format, &dest_value)) - { - g_warning("gstvideo: pad %s:%s failed to convert time to unit!\n", - GST_ELEMENT_NAME(gst_pad_get_parent (pad)), GST_PAD_NAME(pad)); + gfloat fps = 0.; + GstCaps *caps; + + /* get pad caps */ + caps = GST_PAD_CAPS (pad); + if (caps == NULL) { + g_warning ("gstvideo: failed to get caps of pad %s:%s", + GST_ELEMENT_NAME (gst_pad_get_parent (pad)), + GST_PAD_NAME(pad)); + return 0.; + } + + if (!gst_caps_has_property_typed (caps, "framerate", + GST_PROPS_FLOAT_TYPE)) { + g_warning ("gstvideo: failed to get framerate property of pad %s:%s", + GST_ELEMENT_NAME (gst_pad_get_parent (pad)), + GST_PAD_NAME (pad)); return 0.; } - fps = ((gdouble) dest_value) / NUM_UNITS; + gst_caps_get_float (caps, "framerate", &fps); - GST_DEBUG ("Framerate request on pad %s:%s - %f fps", - GST_ELEMENT_NAME(gst_pad_get_parent (pad)), GST_PAD_NAME(pad), fps); + GST_DEBUG ("Framerate request on pad %s:%s: %f", + GST_ELEMENT_NAME (gst_pad_get_parent (pad)), + GST_PAD_NAME(pad), fps); return fps; } @@ -56,28 +61,37 @@ gst_video_get_size (GstPad *pad, { GstCaps *caps; - g_return_val_if_fail(pad != NULL, FALSE); + g_return_val_if_fail (pad != NULL, FALSE); - caps = GST_PAD_CAPS(pad); - if (!caps) { - g_warning("gstvideo: failed to get caps of pad %s:%s", - GST_ELEMENT_NAME(gst_pad_get_parent (pad)), GST_PAD_NAME(pad)); + caps = GST_PAD_CAPS (pad); + + if (caps == NULL) { + g_warning ("gstvideo: failed to get caps of pad %s:%s", + GST_ELEMENT_NAME (gst_pad_get_parent (pad)), + GST_PAD_NAME(pad)); return FALSE; } - if (!gst_caps_has_property(caps, "width") || - !gst_caps_has_property(caps, "height")) { - g_warning("gstvideo: resulting caps doesn't have width/height properties"); + + if (!gst_caps_has_property_typed (caps, "width", + GST_PROPS_INT_TYPE) || + !gst_caps_has_property_typed (caps, "height", + GST_PROPS_FLOAT_TYPE)) { + g_warning ("gstvideo: failed to get size properties on pad %s:%s", + GST_ELEMENT_NAME (gst_pad_get_parent (pad)), + GST_PAD_NAME(pad)); return FALSE; } if (width) - gst_caps_get_int(caps, "width", width); + gst_caps_get_int (caps, "width", width); if (height) - gst_caps_get_int(caps, "height", height); + gst_caps_get_int (caps, "height", height); GST_DEBUG ("size request on pad %s:%s: %dx%d", - GST_ELEMENT_NAME(gst_pad_get_parent (pad)), GST_PAD_NAME(pad), - width?*width:0, height?*height:0); + GST_ELEMENT_NAME (gst_pad_get_parent (pad)), + GST_PAD_NAME (pad), + width ?
