[Bug 923888] Re: XBMC with Gstreamer can't decode mpeg2 properly

 

In screenshot003.png the error is clearly in the upscaling from SD to
display resolution.  The 720x576 input image has been scaled uniformly
to height 1080 resulting in a width of 1350 pixels.  Beyond horizontal
position 1350, the last pixel has been replicated to fill the line up to
1920 pixels.

The same problem is present in screenshot006.png with the addition of
the image being repeated twice vertically at half height.  The top and
bottom halves of this image are almost identical pixel for pixel, which
suggests they are from the same source image, not a top/bottom
interlaced pair or similar (unless the video has *no* motion at all
between frames; a test with a high-motion scene would clarify this).
Possibly a single field has been repeated twice, although the presense
of black borders suggests a film source, which is typically not encoded
with interlacing.

Without access to the actual files being played, I cannot speculate
further.  Also, is this using hardware or software decoding?

Bug description:
  Hi,

  I installed XBMC along with gst from your overlay ppa on my Pandaboard ES. So far everything works smooth (h264, mpeg4). Even 1080p works good.
  The only issue I have is while playing mpeq2 videos. I have some VOB's (DVD backups with mplayer dumpfile) that I can play with my PC with official XBMC 11 (ffmpeg), but on my Pandaboard I have a lot of frame drops and audio is out of sync. Video looks interlaced even though it shouldn't be (deinterlacing doesn't help). In some files 1/3 of the right screen is totally blurry (See attached screenshot). Also as you can see in the attached screeny the CPU usage goes up to 100% which I haven't seen in any h264 1080p video yet.

  Btw. drm polling is turned off
