gst-python: Upgrade old python2 code
Upgrades old python2 code (python2 has been deprecated for 4 years)
Todo:
-
Run py- 2to3
and filter out irrelevant corrections -
Upgrade any gstreamer-0.1x tests --> gstreamer-1.x (Only Pads tests are left) -
Upgrade any other gstreamer-0.1x code --> gstreamer-1.x -
Evaluate what to do with obsolete codeObsolete code removed
TODO in a future MR:
- Fix missing functionality, and make Python Gst API more usable:
- Remove warnings on not specifying min Gst/GLib/.... versions.
- Buffers:
- Make Gst.Buffer("56789") = Gst.Buffer.new_wrapped(b"56789")
- Make _repr_(buffer) = buf.map(Gst.MapFlags.READ).data.tobytes().decode()
- Make len(buffer) = buffer.get_size()
- Figure out how to write buffers in python API, add it here?
- Let Gst.ElementFactory.make() run with a single arg (take None as default arg for 2nd)
- Allow writing to Gst structures from within python
- Tags
- Make Gst.TagList() = Gst.TagList.new_empty()
- Allow creation of non-standard tags / expose relevant API from C (Gst.tag_register() doesn't work)
- GstTag.tag_list_to_xmp_buffer doesn't copy taglist to xmp
- Make Gst.Pad()=Gst.Pad.new()
- Fix the inconsistency in the API - for int ranges, it's
intrange.range.start
vs for doubles, it'sdoublerange.start
- Allow many args to Gst.bin.remove(), it has been overridden for add() already
- Add missing py tutorials
- Migrate the 1 or 2 pending tests
