Hello enpa,
most rockchip-players needs xvid-encoded Videos. You could find some Converters like AVConverter, AVIConverter, viDrop or BatMan here in the Download-section. I'll prefer viDrop 0.56.1 for beginners or AVConverter v1.77.3, if you're a tough Windowsuser who could unhide the hidden Converter.ini and replace this one by the one for RK2606A-Players.
The right values for your 2" player should be:
Resolution: 224x176 (some player only accept 220x176)
Framerate: 20 (or try other values from the range of 20 until 30, stepping: 1
Videocodec: xvid
max B-Frames=4 (some Players needs the value 0!)
Videobitrate=350 or 800 (350 @ B-frames=4, 800 @ B-Frames=0)
quant_type=h263 (not h264!)
Audiocodec: mp2 (not mp3!)
Frequency=44100
Soundbitrate=112
As an extra Mencoder-Parameter in viDrop i'll prefer:
-vf-add expand=224:176:-1:-1:1
or
-vf-add expand=220:176:-1:-1:1
(only if you're trying the resolution 220:176)
This parameter is important, because any RockChip-Chip of the generation RK26xx plays only one Resolution. If the Videopicture is smaller than the resolution, the expand-parameter adds four borders to the videopicture until the resolution has been reached.
Or some players with B-Frames=0 needed the video to be flipped and rotated:
-vf-add expand=224:176:-1:-1:1,rotate=2,flip
or
-vf-add expand=220:176:-1:-1:1,rotate=2,flip
(only if you're trying the resolution 220:176)
Good luck and
rgrds, lca77
