bounties for OpenPOWER optimization

[Daniel Pocock]

IBM recently offered a bounty for work on ffmpeg improving performance
on OpenPOWER.

They are inviting[1] people to propose bounties on any other multimedia
stacks.

Are there any improvements to gstreamer and dependencies that could be
funded this way?

Are there any benchmarking tests that OpenPOWER users (e.g. people with
the Talos II and Blackbird systems[3]) can run to identify bottlenecks?

To propose a bounty, simply create[2] a gstreamer bug report for the
issue and then tell[1] IBM about it.

Regards,

Daniel

The audioresample code in gst-plugins-base has some custom assembly
that could use a Power implementation. Apart from that improvements to
ORC in that regard would be useful and would automatically benefit all
GStreamer code using ORC (including video conversion/scaling).

Thanks, those are great tips

I made brief feature requests for those things and submitted them
through IBM's form.

If you have any ideas to help bounty-hunters get started, you could
include them in the issues or link them to other issues.
