Original commit message from CVS: 2007-05-30 Andy Wingo <wingo@pobox.com> * sys/v4l2/v4l2src_calls.h: * sys/v4l2/v4l2src_calls.c (gst_v4l2src_fill_format_list): Store the format list in the order that the driver gives it to us. (gst_v4l2src_probe_caps_for_format_and_size) (gst_v4l2src_probe_caps_for_format): New functions, fill GstCaps based on the capabilities of the device. (gst_v4l2src_grab_frame): Update for object variable renaming. (gst_v4l2src_set_capture): Update to be strict in its parameters, as in the set_caps below. (gst_v4l2src_capture_init): Update for object variable renaming, and reflow. (gst_v4l2src_capture_start, gst_v4l2src_capture_stop) (gst_v4l2src_capture_deinit): Update for object variable renaming. (gst_v4l2src_update_fps, gst_v4l2src_set_fps) (gst_v4l2src_get_fps): Remove; these functions don't have much meaning outside of an atomic set_caps method. (gst_v4l2src_buffer_new): Don't set buffer duration, it is not known. * sys/v4l2/gstv4l2tuner.c (gst_v4l2_tuner_set_channel): Remove call to update_fps; not sure about this change. (gst_v4l2_tuner_set_norm): Work around the fact that for the moment we don't have an update_fps_func. * sys/v4l2/gstv4l2src.h (struct _GstV4l2Src): Don't put v4l2 structures in the object, just store what we need. Do store the probed caps of the device. Don't store the current frame rate. * sys/v4l2/gstv4l2src.c (gst_v4l2src_init): Remove the update_fps_function, for now. Update for new object variable naming. (gst_v4l2src_set_property, gst_v4l2src_get_property): Update for new object variable naming. (gst_v4l2src_v4l2fourcc_to_structure): Rename from ..._to_caps. (gst_v4l2_structure_to_v4l2fourcc): Rename from ...caps_to_.... (gst_v4l2src_get_caps): Rework to probe the device for supported frame sizes and frame rates. (gst_v4l2src_set_caps): Rework to be strict in the given parameters: if someone asks us to have a certain size and rate, that is what we configure. (gst_v4l2src_get_read): Update for object variable naming. Don't leak buffers on short reads. (gst_v4l2src_get_mmap): Update for object variable naming, and add comments. (gst_v4l2src_create): Update for object variable naming.
