[MPlayer-users] Flicker Black Bars on videos

Hello to all!

I'm using mplayer within an application (XBMC) to play videos.
Launching the player, the video starts smooth in fullscreen, but the black bars (video 16/9) are 
flicker a lot showing the application behind. You can see here an example of the result. You'll see 
the clock and the menu behind.


The video is executed using following line:

mplayer -fs -vo vdpau -vc ffmpeg12vdpau,ffh264vdpau <video>

The system is a BananaPI board on Lubuntu 14.04:

CPU: Allwinner A20 ARM® Cortex™-A7 Dual-Core
GPU: ARM Mali400MP2 Complies with OpenGL ES 2.0/1.1
Memory (SDRAM): 1GB DDR3 (shared with GPU)

To play it in HW mode, I've compiled the vdpau-sunxi (cedar).

In addiction, subtitles are not shown. To show it, I need to use mpv with parameter 
"--force-rgba-osd-rendering". This is not a priority at the moment. With mplayer I got:

[vdpau] EOSD: error when creating surface: An invalid/unsupported VdpRGBAFormat value was supplied.

The vdpau video output is using framebuffer to show the video. Has it something to do? How can I 
troubleshoot and solve this issue? (I mean mainly the black bars issue)

Some notes:
1. Using the player from command-line, it works.
2. Using another player, like vlc, from XBMC, it works (black bars are correct), but not fluid as 
mplayer. I would like to use mplayer.

Thanks for the support!
