Sadly, this thread is suffering from the "vids or it didn't happen" syndrome. :-(

All my "dithermation" stuff needs to be on youtube.

Someday RSN.

This is the way with the gaming generation

FWIW. I have watched your demo enough times for probably 100 people.

Just ran it on my Kindle 3 Keyboard. Impressive enough.

Perhaps people will be more interested when they can do this on their popslates.

Start at first post of page 1, read until you reach this post.
The directions are in there somewhere.

As in: How do you install it? Read the USBnetworking thread.
As in: How do you use it once it is installed? A good question for your favorite web search engine - include the keyword describing your OS in the search.

When in serious doubt - try the prefix index for the places we might have indexed.
That is hidden in a sticky at the top of this forum.

Hi. I ran gmplay with some of the included videos and it worked perfectly.

However, when I tried to convert my own, the picture does a strange rolling thing. I tried using different video formats, different resolutions, different kindles (kindle 3 and 5 main), and two different computers. Always the picture rolls, whether it's from a file or nc.

Sorry, I know this is operator error, but I'm not sure what I'm doing wrong.
I compiled raw2gmv with tcc, if that matters.

You may have the image larger than 800x600. The raw2gmv program assumes that it is raw 800x600 grayscale 8bpp input video with no headers or metadata. It gets rotated to 600x800 during conversion.

Thanks for the fast response, but no - the command I'm using is basically the one you specified for playing a local file:

ffmpeg -i lmi.avi -pix_fmt gray -f rawvideo -s 800x600 -|/root/raw2gmv|nc -l 5555

I attached a few pictures of what I mean. One is from the middle of the movie, and shows the bottom-to-top rolling. One is from the beginning, and shows the left-to-right rolling. Oddly they do both at once - I would expect one or the other but...

Will have a look into this tomorrow if I get the chance or RSN if not

Try piping some of the ffmpeg output to a file. You can just encode a few seconds to keep it small. Then try feeding the file to the raw2gmv transcoder.

If it does not work, zip up that raw file (or a portion of it) and post a link to it so I can look at it. I need at least a few frames of video in the raw file. Thanks...

I suppose it COULD be a tcc problem. I use gcc for my x86 compiles. There is a code:blocks installer that includes it, ready to go (with IDE even)... I usually use command line builds though (batch files), except when debugging...

Get the installer with mingw:

Okay - I piped ffmpeg to sample.raw then played it with raw2gmv and nc to my kindle - I got a slightly faster frame rate, but still rolling.

When I use gcc to compile raw2gmv it seems a little better - when it works. sample.raw played rolling with raw2gmvtcc but didn't display at all with raw2gmvgcc. nc worked better with gcc, I think it only rolled side to side.

EDIT: Actually no, raw2gmvgcc works just the same as raw2gmvtcc. I attached sample.gmv.gz, it was made with raw2gmvgcc and behaves the same as earlier gmv.gz files I've made with raw2gmvtcc.

I attached sample.raw zipped.

I extracted sample.zip, then opened it with IrfanView as a RAW 800x600 8BPP grayscale image. Then I saved it as JPG:



That demonstrates that the first image in the raw sequence looks good. Then I reopened the raw file as 800x6000 (ten frames tall). I resized it to 100x750, and saved it as JPG:



It appears (to the naked eye) to be a good RAW file. It might have some embedded metadata farther down the stream, though.

But at least it LOOKS (mostly) good. The problem may be with your raw2gmv program. Please attach the source and binary that you used. Thanks.

I copied the code fromthis post into notepad++, saved it as raw2gmv.c and compiled it with tcc.

Here's one I made earlier... (also a 32 bit PC version in there)

Thanks for the help, but no - videos behave exactly the same. I think this makes no sense.
