does anyone know how to set the color balance based imx6 & gstreamer?
(setting the video "
BRIGHTNESS" and so on)
I try 3 way to test the pipeline "videobalance" as belowing:
1, use the default value of videobalance:
.....! vpudec ! videobalance ! mfw_isink....
test result : every thing goes well.
2. static way to set the videobalance (no default value)
.....! vpudec ! videobalance brightness=0.5 contrast=1.1 ! mfw_isink....
test result: high cpu loading(about 60% in one of cpu core), and the fps of the playing video is very low.
3. Dynamic way to set the videobalance based on gstreamer C api.
a) goes well in my ubuntu PC.
b) in imx6: it can play the webm source based HTTP profile. but when setting the "contrast" "brightness" of video, it fail !
and tell some error!
dear all and fsl people, would you pls help to give some advices.what i Actually need is : I s there any way to set the colorbalance(contrast and brightness) of video or the whole screen? (beside of gstreamer function, is there other way to set the colorbalance?)
thanks so much!
