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.
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 ! ;-)
