Yes, I also build the theora plugin.
I did a short test this morning:
Theora and vorbis on n800
I transcoded the "Discovery.avi" with ffmpeg2theora with the default settings.
Theora video:
352x208
1) theora video only
gst-launch-0.10 filesrc location=Discovery.ogg ! oggdemux ! theoradec !
xvimagesink
cpu: ~45%
The theora video is beeing played in a window not full screen. The video
playback is good. No skips. :-) Looks promissing. I will try some higher
resolutions & frame rates soon.
2) theora video and vfp-vorbis decoding
gst-launch-0.10 filesrc location=Discovery.ogg ! oggdemux name=demuxer !
{queue ! theoradec ! xvimagesink} {demuxer.!queue ! vorbisdec !
audioconvert ! dsppcmsink}
cpu: ~ 80 (45% & 35%)
Vorbis playback using the vfp causes ~35% cpu. Theora decoding is like in 1).
It adds up to ~80% and I experienced many skips. Playback is not in sync,
halts, skips ... :-(
However when I try to use tremor (just takes ~12% cpu) based audio decoding I
am out of luck.
If it is possible to let the tremor plugin do the audiodecoding, what would be
the right gst-lanuch string?
I need some advice from you gst gurus!
Regards Krischan
PS: 770 & n800 are not _just_ internet tablets. They are a hell of a
multimedia device. The more time I spend using my n800 and 770 the more
impressed I get!
