geekmaster kindle video player

[twobob]

whats the exact revision of your device...

and the exact commands ON BOTH ENDS that you run...

[sean.fosterbrown]

I have a Touch 5.1.2 and a Keyboard 3.4.

On my computer I run:
To send the video to a file:

ffmpeg -i <FILE> -pix_fmt gray -f rawvideo -s 800x600 -r 7.7 -|/root/raw2gmv|gzip > file.gmv.gz

To send it to the kindle via nc:

ffmpeg -i <FILE> -pix_fmt gray -f rawvideo -s 800x600 -|/root/raw2gmv|nc -l 5555

On my kindles:

zcat file.gmv.gz|./gmplay

or

nc 192.168.1.3 5555|./gmplay

[twobob]

PC:

me@dev ~ $ ffmpeg -i /home/me/BACKUPS/backup/BarbiePt1.avi -pix_fmt gray -f rawvideo -s 800x600 -| raw2gmvPC |nc -l 5555

Touch 5.3.2:

[root@kindle us]# nc dev 5555 | ./gmplay

Plays as expected... hmm...

You tried a few movies?

Wow! these videos are pretty neat! They work fine on my Touch - I didn't netcat them, just copied and played them. Sure makes a great demo, though I can't imagine watching an action flick all the way through?

Do I understand the only way to get sound is to play both streams simultaniously? like with mplayer or ffmpeg?

Wait... so I'm learning something new every day. I never knew that netcat could work in the "wrong direction" - have the sending end listen, and the receiving end connecting to it. Weird but cool

I've try to run ffmpeg+raw2gmv+raw2gmv directly on my KT but it didn't work.
First run ffmpeg+raw2gmv+nc on KT5:

./ffmpeg -i tj.mp4 -pix_fmt gray -f rawvideo -s 800x450 -|./raw2gmv | /mnt/us/nc -l 5555

Result:

Hi. Why would you use netcat on the same device?

That part of the solution is to provide "paused" network traffic from a remote device.

./ffmpeg -i tj.mp4 -pix_fmt gray -f rawvideo -s 800x450 -|./raw2gmv | ./gmplay would be the correct solution. IF it worked on one device. As far as I remember it doesn't work on one device. A blank screen is outputted.



With regards to your ACTUAL setup. you said. /mnt/us/nc -l 5555 so that would be port 5555 so the other bit would be nc localhost 5555

It's kind of early in the morning here but that would maybe be the wrong end of the socket you identified or something, not awake properly.

Hello.

I've completely failed to get gmplay to work. I keep it and gmvid in a directory mnt/us/videos and use the following commands from XTerm:

cd mnt/us/videos/
zcat gmvid.gmv.gz|./gmplay

And I get:

zcat: error inflating
zcat: broken pipe

I have looked at the rest of this thread and found nothing helpful. Help would be appreciated.

[brianinmaine]

I got it work, maybe you could show what video you are trying (one of the first links on this thread) then re-download and copy over the version you have? maybe the video you have wasn't downloaded fully?

I tried playing Gmvid. I redownloaded that and gmplay, and this time I got a page or two full of characters in XTerm ending with:

zcat: error inflating
zcat: broken pipe

cd /mnt/us/videos/ not
cd mnt/us/videos/

did you try a ls just to check you were in the right place?

just a thought...

I used cd /mnt/us/extensions/videos/ instead, and then ls. It turned out I was in the right place, and the problem remained.

[knc1]

The command (present working directory):
pwd
will tell you where you are at.

Just entering:
cd
in *nix will return you to your home directory, not show you where you are at like some other OS cd commands do.

[icantbebothered]

Well I've been a bit of an idiot. I didn't realise gmplay-1.5a was an archive. Once I unpacked it into mnt/us/extensions/videos/ everything went smoothly.

And now to celebrate by giving everyone ridiculous amounts of karma.
