f499810bdc theoraenc: Set speed level while running 2011-02-17 18:29:56 -08:00
Ralph Giles
d467eb708a Set the theoraenc speed-level property from libtheora's defaults.
The speed-level property, which allows callers to trade of encoding
quality for speed in the libtheora api, has a version-dependent
maximum and default values. Instead of hardcoding the acceptable
range for the theoraenc element's presentation of this setting,
we query the library directly at class initialization time and
set the maximum and default values from that. If the query fails,
we fall back to the previous default setting.

To keep the values reported by gst-inspect (which I'm told use
the spec values from the class) with those available on an\
instantiated element, we remove to setting of enc->speed_level
from the initializer and instead pass G_PARAM_CONSTRUCT to
the property spec flags, asking g_object to set this property
when theoraenc objects are constructed.

NB in theory the maximum speed-level could depend on the actual
video caps. If later versions of libtheoraenc do this, a second
call will need to be made from theora_enc_reset to update the
property, since this function is mostly useful for realtime
adjustment of performance while the pipeline is running.

46f3e7c6fd theoraenc: Don't reset the video quality setting the bitrate
libtheora has two encoding modes, CBR, where it tries to hit a target
bitrate and VBR where it tries to achieve a target quality.

Internally if the target bitrate is set to anything other then 0 the
encoding-mode is CBR.

This means that the gstreamer element can leave the video_quality
setting alone as long as the user is tweaking the bitrate. Which has the
nice side-effect that if the user explicitely sets the bitrate to 0
(which is actually the default), the quality value doesn't get reset and
one ends up encoding VBR at quality-level 0...

9805bdfcc8 theoraenc: clean up property descriptions
Remove "This property requires libtheora version >= 1.1" qualifiers
from property descriptions. They aren't needed any longer now that
we require libtheora >= 1.1.

5318e71b4d configure: Require libtheora >= 1.1
It's more than a year old at the time of the next -base release,
has many encoder and decoder improvements and gets us rid of a lot
of #ifdefs
