What are the manifest and license server URIs?

manifest:
https://content-ausw2-dt-man1.downlynk.com/34c2e8dc7078462a80fcf9c461ba0073.mpd?prettydash=1&ifo=1&vcodec=all
license server:
https://content-ausw2-dt-man1.downlynk.com/wv

What did you do?

Enable Trick mode controls and then enagage trick mode:

What did you expect to happen?
There are 2 trick mode adaptation sets one HEVC and one AVC -- There are also AVC and HEVC video representations. Shaka picks the video representation that it can play (avc) but then when you engage trick mode it appears to pick the HEVC trick mode representation.

What actually happened?

After engaging trick mode you get:

Shaka Error MEDIA.VIDEO_ERROR (3,,CHUNK_DEMUXER_ERROR_APPEND_FAILED: Append: stream parsing failed. Data size=854 append_window_start=0 append_window_end=434.794)

I can restrict the the codecs included in the manifest using url parameters to my manifest server, and if I simply remove the HEVC representations, trick mode will engage fine:

using:
"https://content-ausw2-dt-man1.downlynk.com/34c2e8dc7078462a80fcf9c461ba0073.mpd?prettydash=1&ifo=1&vcodec=avc"

and the same license server.
