With v6, we can encode using daala, and to make it easier to debug we can also record the output stream to a file (which should be generalized) as well as sending it to the client using:
XPRA_DAALA_SAVE_STREAM=basefilename XPRA_DAALA_DEBUG=1 xpra start --start-child=xterm :10
Then if I view the stream saved by the server using daala's example player I see:
So it looks like daala may have some serious encoding problems!
Unfortunately, the decoding side (client) does not work... despite doing exactly the same calls, in exactly the same order as the example daala client. This can be verified by applying the daala-example-player.diff patch to the player and running the daala xpra test with the ogg stream we have recorded:
;XPRA_DAALA_DEBUG=1 LD_LIBRARY_PATH=/usr/local/lib64 PYTHONPATH=. ./tests/xpra/codecs/test_daala.py xterm-daala.ogg
(for the record, everything also builds fine on OSX after installing check.sf.net)

- status changed from new to closed

I've asked on the mailing list and got no reply, although the daala source tree does see some updates, if the mailing list is any sign... this project does not care and neither should we.
