GstSrc The start point of a filter graph A GstSrc is the start of a filter graph. It typically is a file or an audio source. It provides data for the next element in the graph. GST_SRC_ASYNC this source is assynchronous @GST_SRC_ASYNC: This macro returns the entire set of flags for the object. @obj: GstSrc to return flags for. This macro checks to see if the GST_SRC_ASYNC flag is set. @obj: GstSrc to check for flag in. This macro sets the given flags. @src: @flag: Flag to set, can by any number of bits in guint32. @obj: GstSrc to set flag in. This macro usets the given flags. @src: @flag: Flag to set, must be a single bit in guint32. @obj: GstSrc to unset flag in. @src: @src: @src: @offset: @size: An eos signal is triggered whenever the GstSrc has reached the end of the stream. @gstsrc: the object which received the signal. @arg1: the object which received the signal
