File - Sample Rockchip videos with different screen sizes

Description:

Rockchip sample videos with different screen sizes.

- You wanna try a new MP4-Player before buy ?
- You wanna check the MP4-player of a friend ?
- You wanna check your own old MP4-Player ?
- You wanna know which videochip is built in the mp4-Player ?

Try it with these handpicked and wellproofed AVI-Videos. The MP4
won't play xvid-coded Avi-Files ? Too bad, do not read any further
and delete this useless videos immediately.

How to perform this test:

0.
Read these instructions from the beginning to the End befory you do
anything else. Act only at second reading.

1.
Copy this 21 videos in alphabetically order into a microSD, miniSD or
SD-Card with 100MB free Space. Copy them into an new, fresh and empty folder called like VIDEO or anything similar the mp4-Player dictates.

Here are the names of the 21 Testvideos:

TV_128x128_18fps_xvid_mp2_1m06s.avi
TV_128x128_20fps_xvid_mp2_1m06s.avi
TV_160x128_12fps_xvid_mp2_1m06s.avi

TV_400x240_25fps_xvid_mp3_1m06s.avi
TV_400x240_30fps_xvid_mp2_1m06s.avi
TV_400x240_30fps_xvid_mp3_1m06s.avi
TV_480x272_25fps_xvid_mp2_1m06s.avi
TV_480x272_25fps_xvid_mp3_1m06s.avi
TV_480x272_30fps_xvid_mp2_1m06s.avi
TV_480x272_30fps_xvid_mp3_1m06s.avi

2.
Copy these instructions into an folder about ebooks for your mp4-player.

3.
Place the SD-Card into the mp4-player. Instruct him to play all files in a folder once and in alphabetical or logical order (when possible).
Start this Video first/now: TV_128x128_18fps_xvid_mp2_1m06s.avi

4.
Count the "File Format error"- or "Unknown format"-Messages until the first video appear on the mp4-dislay. It shows the guessed Videochip, the resolution, the pictureframerate and the soundcodec. You've got a first success !

Variant A:

Only the next following video is playable too, thats meaning: the Videochip is the one both videos have guessed. Following combinations of playable videos are leading you to the right videochip:

TV_128x128_18fps_xvid_mp2_1m06s.avi
and
TV_128x128_20fps_xvid_mp2_1m06s.avi
should identify the Videochip as RK2602A from RockChip

TV_160x128_12fps_xvid_mp2_1m06s.avi
and
TV_160x128_15fps_xvid_mp2_1m06s.avi
should identify the Videochip as RK2602A from RockChip

TV_224x176_20fps_xvid_mp2_1m06s.avi
and
TV_224x176_24fps_xvid_mp2_1m06s.avi
should identify the Videochip as RK2606A from RockChip

TV_320x240_20fps_xvid_mp2_1m06s.avi
and
TV_320x240_22fps_xvid_mp2_1m06s.avi
should identify the Videochip as RK2608A from RockChip

TV_320x240_24fps_xvid_mp2_1m06s.avi
and
TV_320x240_25fps_xvid_mp2_1m06s.avi
should identify the Videochip as RK2608A from RockChip

TV_220x176_18fps_xvid_mp2_1m06s_Smart.avi
or
TV_224x176_20fps_xvid_mp2_1m06s_Smart2.avi
should identify the Videochip as RK2606A from RockChip

Variant B with acknowledge of Variant A:

More then 2 videos are playable, but smaller videos will be stretched in height and width, until the height reaches the displayborder. The videochip must to be one member of RockChips RK27xx-line.

Variant C with acknowledge of Variant A & B:

More then 2 videos are playable, but smaller videos will be 4side-bordered with black stripes. The videochip could be one member of RockChips RK27xx-line, but the Autostretch-function is switched off (by the firmware or by the user?) or it may be a SigmaTel-Chip from their line STMP37xx they've developed in 2007.

Variant D with acknowledge of Variant A & B & C:

The resolution of the last played video was bigger than the displaysize of the mp4. The videopicture was cutted but watchable: this must be a chip of the STMP37xx-line, because Rockchips won't play videos with oversize !

Some Notes:

The first playble videoshows the minimized values of width & height, framerate and soundcodec. The last playable video shows the maximum of this values. Don't leave this frontiers behind you ! But you're able to play with sound- and videobitrate - if you like to...

Some errors depends on "Motion search precision": the lowest level is zero, the highest is six, stepping one. Some players need the value set to zero, other need it as 4 and otherohterones need 6 - try it at your own risk ! ;-)
