Hi there...
how and what software do you guys test the video performance on meego?
1. frame-rate
- Beside the "fpsdisplaysink" in bad plugin to shows the framerate, any
others?
2. CPU consuming
- how?
3. Other
We have several ways of looking at media performance in general.
First we do what everyone can do: Just play media, and see if the
quality is acceptable (no tearing, stuttering, sound stays in sync etc).
We generate several sizes of video to figure out what the capabilities
of devices are and pick suitable video resolutions and bitrates from
there on.
Second there are people working on a more methodical analysis such as
cpu utilization during playback, power consumption, etc. We mostly try
to actually use the media stack that the end user will see in those, and
not some artificial way of launching the video without the UI involved.
For more information on methods, follow the phoronix test suite, they
have published a great deal of test methods that are free to download,
inspect, use for everyone and will show you how you can measure various
parts of media playback performance.
