description: Show data based on properties of the producer.
notes: |
The data show filter uses data provided by the data feed filter.
The producer properties must supply: >
* The keyword text to be inserted in the form of:
meta.attr.[keyword].markup=[text to insert]
* The name of the properties to be used from the feed file in the form of:
meta.attr.[name]=1
* The text to be displayed in the form of:
meta.attr.[name].markup=[some text #keyword#]
(Keyword text is enclosed between #s.)
e.g.
melt file.dv meta.attr.sometext.markup="this is some text" meta.attr.titles=1 meta.attr.titles.markup=#sometext# -filter data_show dynamic=1
>
Two special keywords exist
* #timecode# shows the frame position as a timecode.
* #frame# shows the frame position as an integer.
e.g.
melt file.dv meta.attr.timecode=1 meta.attr.timecode.markup=#timecode# -attach data_feed:attr_check -attach data_show:custom_file.properties dynamic=1
(where the file "custom_file" contains a filter definition by the name of "timecode")
