[PATCH 0/1] MR5460: mfmediaengine: Allow decoders to be resolved before optional effect nodes.

[Rémi Bernon (＠rbernon)]

Otherwise pipelines fail to resolve when media source outputs compressed samples and applications have inserted optional effects (such as VRChat with AVPro player).

Note that the topology loader doesn't currently support MF_CONNECT_AS_OPTIONAL, although the connection succeeds in the the cases I've seen.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

Yes, this makes sense. But should it allow decoder-converter connections between effects? My understanding is that currently we do "source -> effect0 ... -> effectN -> sink", that gets resolved to whatever the loader thinks is best, but don't allow nodes before any 'effect*' node, not just the first one.
