viDrop - free open-source converter for RockChip players

Mr. K · #**141** (**permalink**) 12th Aug 2008, 2:14 am

Hi All

I just dowloaded/installed vidrop (0.56.1) and tried ripping one of my dvd's. Unfortunately, the program couldn't find the dvd drive for some reason. I clicked on the dvd button and saw the "Loading" message but then it didn't seem to find the drive. If I click on the info "i" button all the info is blank. If I click on the Preview or Convert buttons I only get one or two command line windows that pop up and immediately close. I do have a number of hard drives/cd/dvd drives in my pc that may(?) be causing the problem. The drives are:
C: (hard drive)
D: (hard drive)
E: (HP recovery partition)
F: (CD/DVD RW drive)
G: (CD/DVD ROM drive)

Any ideas why I can't read from the F: & G: drives? I've tried both.

I tried searching for the answer to this question in the forum but didn't get any hits. If it has been answered before please point me in the right direction. Thx

The program sounds just like what I'm looking for but I can't open it. I have installed several versions but after I run the .exe file the programm won't open. I use windows ME

I love this program!!!... it works GREAT with the video I've downloaded and converted... until I try to convert a full movie. When I try to convert, my computer freezes at about 90% complete.

I've converted files from programs that are about a half hour long with no problems. Any idea what I can do??

Well I didn't figure out how to stop Vidrop from freezing, but I worked around it by converting the movie in a different converter first, to reduce the file size, then used Vidrop to get it to work on my player.

Hi guys,

Wow amzing stuff.

Works great, but one question!

It has been mentioned before, just need a clarification.

When using vidrop for my rockchip player is it possible to convert 16:9 in such a way that the ends are not cropped?

It appears i have a generic player:

2.8" TFT LCD color touch screen Pixels: 320 x 240

Buit-in separate audio Sangxing chipmakes

Dimension: 95 x 56 x 14mm. Weight: 98g

Everything workd great, just the cropped 16:9 is annoying.
Any ideas?

Thanks.

Try a width of 320 and the height of 180 pixels under the tab of "Advanced settings". Do not forget to use these term

-vf-add expand=320:240:-1:-1:1

as an "Extra parameters" for "mencoder" or the result maybe not playable on your MP4 without this additional parameter - especially on RK2608A based mp4-players. rgrds, lca77

Thank you very much this is a fanstastic software it works great for my generic rockchip mini mp4 player.

However, it seems like this converter doesnt support rmvb files? i can't convert any rmvb files into avi is this a bug or is rm files simply not included?

thanks

Hi, I have a SuperTalent Vidego28 which is uses the rockchip 2608a chip. It is a 2.8 inch 320x240 player. I always run into the problem of video lagging behind the audio. It starts out synched, but slowly comes out of sync. By the end of a 1 hour show, it is off by 3-4 seconds.

I've tried many options, always with the same result. Is it possible that the problem is with the source files? I have been testing with an mpeg downloaded from my tivo. It plays fine on the PC. When I convert to AVI with any converter that I have tried, they play fine on the PC, too, but slowly go out of sync on the player.

Any ideas? i have tried the "-speed 0.96" option, I have tried 20, 22, 24 fps. Nothing seems to help.

thanks!

forgot to mention, If I ff or rw a few seconds, the audio resyncs, then slowly goes out of sync.

Hi jangelj,

which values of audio- and videobitrates are you using ?

Please try the following values and post your results/opinions after testing:

SRate=44100
VideoBitrate=400
AudioBitrate=128
MotionEst=4
CmdLine=-speed 0.96 -vf-add expand=320:240:-1:-1:1
FPS=24

These are the values I've written for the "50 new presets for vidrop: PAL Rockchip 320x240 high.ini" - you could find them under "Downloads/Tools. rgrds, lca77
