I have a Touch 5.1.2 and a Keyboard 3.4.
On my computer I run: To send the video to a file: Code:
ffmpeg -i <FILE> -pix_fmt gray -f rawvideo -s 800x600 -r 7.7 -|/root/raw2gmv|gzip > file.gmv.gz Code:
ffmpeg -i <FILE> -pix_fmt gray -f rawvideo -s 800x600 -|/root/raw2gmv|nc -l 5555 Code:
zcat file.gmv.gz|./gmplay Code:
nc 192.168.1.3 5555|./gmplay |

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

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. |

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?

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. |

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. |
