Video with H.264 codec and 50 fps has decoded incorrectly

Postby geomaster » Sat May 18, 2013 9:48 pm

Videostream with H.264 codec and 50 fps has decoded incorrectly in hardware mode. For example:
  • player: MX Player with H/W+ mode and NEON support
  • stream: Russia Today
Player tell me - video has 25 fps (wrong!!! check with VLC - 50fps) and picture has broken
Image Image Image
You can see, hardware decode is enable, but video not so good. In software mode all video is fine.
And look at the picture in VLС on PC and stream data (fps marked blue)
Image
It's not player bug - VPlayer, VCL for Android and many other players with support H/W decode make picture like MX Player.

Can some help me?

Try decoding in H/W mode (not +). For most videos it gives great performance but some come out wrong.

Nothing to do about that I guess, there must be something in the codec that isn't hardware supported, you'll have to go with software decode.

Do you have the latest firmware? If not, you could try if that works (there's no info about what it does but there may be some hardware acceleration tweaks).

Don't update if you rely on or will need VNC, sadly the update breaks VNC functionality.

I try firmware from 20121224 till 20130510. Same results... Sadly, but only S/W mode correct for this stream. Thanks.
