hey

<Simy>

yay sombodys awake! :)

<Dark_Aurel>

Yes..

<Simy>

this may be a stupid question, but how do you view a jpg?

[09:17]

<Dark_Aurel>

i don't completely understand your question... What exactly you want to do?...

[09:17]

<Dark_Aurel>

You want to view jpgs on OSD?

[09:17]

<Simy>

yeah....

[09:18]

<Simy>

I took my sisters camera, stuck in an sd card, took a couple videos and a couple pictures, I can view the very very short 'movies' but I cant see the pictures themselves

[09:18]

there is an image browser somewhere

[09:18]

<Simy>

I can see the files, I just don't know how to view them, when I click on them with the remote, I can copy, delete etc...

i can't try now, but it's definitely there

<Simy>

ok, so I need to get an image viewer

<Simy>

or is it allready there?

<Simy>

I'm also havingg trouble with my USB HD

no, you need to get to the image viewer that is the osd software already. unless they removed it, it's a bit i don't use that

[09:20]

<Simy>

Its not a big deal, was just hoping to see how it would look on the TV

[09:20]

<Simy>

I must say I'm impressed with the mpeg4 format for its size/time ratio!

[09:20]

<Simy>

I recorded half an hr or somthing like that on a 256m sd card, and it still wasnt full!

[09:22]

<Simy>

Also, I had v 3.28-0.63 but went backwards becaused I couldnt see any videos (I could hear them though) and I went to 3.27-0.58

[09:22]

<Simy>

But Now I have trouble with my USBHD, where could I read more about this, or how to fix it, or is it in the works?

[09:23]

what problem you have with that ?

[09:24]

<Simy>

well when I had 3.28 I could see it and record to it, but I couldnt actually view the images on the HD, now that I've gone down to 3.27 when I can see and get into the HD, I cant see any files on it

[09:25]

<Simy>

and with 3.27 when trying to record it says no storage found

[09:26]

it probably fails to mount it. so you see just the empty dir

[09:27]

i suggest to move to 3.28 if USB worked there, then have a little patience for next release to fix videos again.

[09:27]

or try to mount the usb hard disk manually

[09:28]

<Simy>

thats what I was thinking, but somepeole have had it working, so I soppose it depends on the version?

[09:28]

<Simy>

its ext3 if that matters

[09:28]

<Simy>

I took it out, put it in my server, and used the debian install disk just to get it to fdisk it

[09:29]

ah, i'm not sure about ext3. fat32 disks worked fine in .63 for me

[09:29]

<Simy>

How do I go about getting it to fat32?

[09:29]

<Simy>

I've had ALOT of trouble doing anythign with this while its USB

[09:30]

<Simy>

I tried some swissknife program, to format it, but that didnt work, could be read by xp, my debian box, or the OSD

[09:31]

i would just use mkfs.vfat on the device

[09:32]

<Simy>

on the OSD?

[09:32]

<Simy>

or with a linux box?

[09:33]

from anything running linux. call mkfs.vfat telling it to format the usb disk device. it's usually /dev/sda1

[09:34]

<Simy>

ok, I'll try that.....

[09:34]

<Simy>

but shouldnt ext3 work better then vfat?

[09:35]

vfat is more common for usb disks. if you ever want to attach your usb disk to anything non-linux it will probably support vfat.

[09:36]

<Simy>

But I dont care about that, lol

[09:36]

<Simy>

my laptop dualboots, my sever is linux, and the OSD is linux...

[09:37]

can you confirm that mounting it manually from the osd as ext3 works ?

[09:37]

<Simy>

I dont know how

[09:37]

<Simy>

I know it HAS worked with the latest firmware, BUT it wouldnt show video

[09:38]

<Simy>

and it seems to drop soemtiems (which I've noticed with my server with a usb hd) then it needs to be turned off and back on....

[09:40]

can't help you more than this with ext3, i don't have any formatted ext3 disks to try

[09:41]

<Simy>

well, i know it works, I guess I'll just keep trying versions untill I can use and view/record to it

[13:17]

<Dark_Aurel>

is anyone alive?

[13:19]

Dark_Aurel: yes ?

[13:22]

<Dark_Aurel>

nerochiaro, i have some questions.

[13:22]

<Dark_Aurel>

nerochiaro: firstly, what part of existing firmware is proprietary?...

[13:23]

<Dark_Aurel>

nerochiaro: codec plugins, and some kernel modules. Something else?

[13:23]

basically all that runs on the DSP and some of the kernel modules that integrate with that

[13:24]

basically yes, what you said

[13:24]

<Dark_Aurel>

ok...

[13:29]

<Dark_Aurel>

for example: /lib/libasf.so - is it open library of closed/proprietary?...

[13:31]

i think it's closed. i don't see any source for it in svn, but i might be wrong

[13:32]

most of the stuff that's related to media isn't open, as far as i know of

[13:32]

<Dark_Aurel>

i think so too... And it's very sad too, bcs i can't find any headers for this lib...

[13:33]

well, i'm not sure what's that for actually. i thought all the media-related libaries were in /usr/local/plugins

[13:33]

but probably the libs in plugins just call into these other libs

[13:34]

i'm pretty sure if you ask to Gao in mailing list he will be able to give you a more precise answer

[13:34]

<Dark_Aurel>

ok, i'll try...

[13:34]

anyway, notice how every library in plugins has basically one corresponding library in /lib

[13:38]

<Dark_Aurel>

yes... also i'm grepping through sources... to find any info about libs in /lib...

[13:40]

<Dark_Aurel>

btw, who is Gao?...

[13:40]

Michael Gao, head of software developement at Neuros

[13:41]

<Dark_Aurel>

Ok... Thanks...

[13:42]

you're welcome. let's hope in an answer, because i'm curious too

[13:44]

<Dark_Aurel>

does anyone has ldd util for ARM? I didn't found it in toolchain.

[13:44]

<Dark_Aurel>

arm-linux-ldd

[13:47]

maybe they are somewhere under linux-r3-extra-apps

[13:47]

<Dark_Aurel>

searching...

[13:48]

<Dark_Aurel>

no...

[13:48]

don't know then

[13:56]

<Dark_Aurel>

Heh...

[13:56]

<Dark_Aurel>

I found replacement for ldd

[13:57]

<Dark_Aurel>

oneliner: arm-linux-objdump -x your-file.elf | grep NEEDED

<Dark_Aurel>

and i made such experiment

<Dark_Aurel>

I've written simple script:

<Dark_Aurel>

#!/bin/sh

<Dark_Aurel>

echo "File -- $1"

<Dark_Aurel>

echo "Depends on:"

<Dark_Aurel>

arm-linux-objdump -x $1 | grep NEEDED

[14:01]

<Dark_Aurel>

and then i've run the following: find . -type f -perm /111 -exec ./1.sh {} \; | grep libasf.so

[14:02]

<Dark_Aurel>

there were no executable files depended on libasf.so.

[14:02]

<Dark_Aurel>

At all...

[14:03]

<Dark_Aurel>

any ideas?...

[14:16]

Dark_Aurel: other libraries maybe ?

[14:19]

<Dark_Aurel>

nerochiaro: what do you mean?... explain, please...

[14:19]

no executable might use that library directly, but another libray might use it

[14:20]

also, there's another possibility

[14:20]

which is that the libraries are loaded dynamically

[14:20]

<Dark_Aurel>

if other library use it it has to be linked to it. Or it need use dlload() to load it, hasn't it?

[14:21]

i am quite sure that the libs in the plugins dir are loaded dynamically, for example

[14:21]

<Dark_Aurel>

I also searched text "libasf.so" in all the files of firmware - no matches.

[14:21]

yes, i mean dlload() when i say dynamically

[14:22]

well, this is what i think: 1) cooler uses dlload to load one library in plugins. the library in plugins (which is closed source) uses dlload to load the corresponding library in /lib

[14:22]

well, just 1. ;)

[14:23]

<Dark_Aurel>

nerochiaro, in this situation, plugin must contain "libasf.so" string in its binary file. But i found no such text much.

[14:23]

<Dark_Aurel>

*match

[14:23]

<Dark_Aurel>

sorry

ah, right

then it's a mystery

for me too

<Dark_Aurel>

hm... may be these files (libasf.so, libaac.so, so on) are just forgotten to be deleted?...

[14:25]

i don't think so, but everything is possible. really this is a question for Gao

[14:25]

and if they really need to be deleted, you will have helped up freeing some space on the OSD, which always help

[14:25]

<Dark_Aurel>

Ok, i'll ask him.

Dark_Aurel : it's a dark voodoo magic :)

yes, thanks

<Dark_Aurel>

btw, how much space has OSD?
