MP0: what you mean with overlay ?

MP0: overlay to render the text, or overlay to store CC in MP4

?

i kinda mixed topics, sorry

<MP0>

okay, yeah, we're talking about a few different things

[01:48]

<MP0>

I was thinking it might be possible to use the overlay to get the analog TV out to contain caption data.

[01:48]

<MP0>

As for getting the CC data into the output of the codecs...

[01:49]

MP0: to get into the analog TV output the CC data, rendering text to the GUI layer (overlay) is the way to go

[01:50]

MP0: for the codecs, it seems really not feasible with the current system

[01:50]

<MP0>

it's an approach, although I'd prefer to find a way to get the raw caption data out instead.

[01:50]

MP0: save it to text files (subtitle files) ?

[01:51]

<MP0>

you still need timing information.

[01:51]

<MP0>

as for the codecs, I don't necessarily need to modify the codecs, I'll probably just patch the output. I'm not really worried about the closed nature of the codec.

[01:51]

subtitle formats (.srt, .sub etc...) allow that timing info

[01:52]

MP0: "patch" the output ?

[01:52]

<MP0>

yes, but you need to get the timing from somewhere

[01:52]

<MP0>

which means having an idea how far the encoder has gotten.

[01:53]

MP0: or you can use the OS time functions to just timestamp the start of the recording, and then the difference from that at each CC change

[01:54]

<MP0>

won't you get out of sync after a while?

[01:54]

good point. i guess it depends if you drop frames or not.

[01:55]

<MP0>

I was going more for:

[01:55]

<MP0>

proprietary codec -> fwrite -> me combining with CC data -> fwrite -> file

[01:55]

you do the combining on the file on disk as it's being written ?

[01:57]

<MP0>

I haven't investigate it enough at this point. I will probably try to at least get timing information from the imanage api.

[01:58]

that is ok, it has that information. i think you can get it from the iencode api actually

[01:58]

but more than that, i'm not at liberty to help you :(

[01:59]

<MP0>

I wouldn't worry about me :-) The proprietary stuff hasn't given me a problem yet.

[01:59]

that's great :)

[02:00]

regarding the thing you said before about "combining" the CC data with the video, i'm not sure how you plan to do that

[02:00]

<MP0>

well, I know MP4 supports embedding CEA-608 caption data into a stream.

[02:00]

<MP0>

lots of products mention having the capability to work with that

<MP0>

like Apple's QuickTime

<MP0>

so I think MP4 supports having the data

the MP4 encoder is closed as well, though

<MP0>

I don't need to touch the encoder.

you can probably post process the stream and inject the data into the stream later

<MP0>

exactly

[02:02]

<MP0>

and like you said, there's also the option of generating separate subtitle files

[02:02]

<MP0>

however I'd like to get the caption information combined into the MP4...

[02:03]

<MP0>

but so far I haven't found an example MP4 file with close caption data in it.

[02:03]

me neither

[02:04]

<MP0>

lots of products mention supporting it, but google doesn't seem to reveal what the specification is.

[02:04]

might be one of these awful specs that you have to pay for just to read them

[02:06]

<MP0>

Do you guys have the MP4 specs?

[02:06]

not that i know of. we didn't write the codec and the parser, we just tweaked it a bit

[02:07]

<MP0>

k

[02:07]

the parser, that is. the codec, totally untouchable for us

[02:07]

<MP0>

okay. Do you know anyone who might be familiar with the spec?

no, sorry

<MP0>

alright, thanks

the people at video-specific forums, maybe, like doom9 or such places ?

or the ffmpeg people ?

[02:09]

did you check if ffmpeg has code related to that stuff ?

[02:09]

<MP0>

I'm investigating that... good idea about doom9

[02:22]

<MP0>

got it! tecnocato.podbean.com

[02:22]

<MP0>

a previous post gives a sample captioned video

[02:27]

good luck then !

[02:27]

<MP0>

Give it a few more weeks :-)

[02:29]

MP0: is the CC char device already available somewhere ?

<MP0>

paul.bluereboot.net

<MP0>

right now it only does NTSC captioning so if you're out of the US... oops

MP0: i mean the source, sorry

<MP0>

ah, that's a piece of crap but if you really want to see it

[02:31]

<crweb>

nerochiaro: i'm having the hardest time making a upk that will flash

[02:31]

<crweb>

its blocking everything

blocking as in freezing ?

<crweb>

no, blocking progress

<crweb>

i can't test anything I've written

<gremlin[it]>

morning nerochiaro & crweb

<crweb>

its crunch time and i can't get the blepity bleep... bleep..

<MP0>

paul.bluereboot.net

crweb: can you please talk with Peter and confirm that you two are following the same process to create the UPKs ?

<crweb>

nerochiaro: ./build-helper.sh all .... worked friday

MP0: thanks, i'll just give it a look out of curiosity later

crweb: what did you change since then ?

<crweb>

i changed some bootup scripts in a fresh checkout

if you rollback to friday's code, it works again ?

<crweb>

says bad checksum when I try to flash..

<crweb>

hmm..

<crweb>

do you have time to help me with svn, or should I just go read?

crweb: -r option, in a nutshell

<crweb>

i'd need to do all trees though

<crweb>

ok

[02:36]

for d in * ; do svn up -r whatever $d ; done

[02:36]

or if you can stand a full checkout, svn co has the same option, IIRC

and you will probably get tricked by timezones and such, so beware

<crweb>

well, any time prefriday should work

indeed

another more quick thing you can try

[02:38]

is to try making upks that have only one component in them (uboot, rootfs, etc) and see if they flash, and what is the componenet that cause issues

<crweb>

well it goes:

<crweb>

Loading your update package: ....

<crweb>

Beginning Flash (Pong game)

<crweb>

red letters Error Error Error, then NSD

[02:40]

<crweb>

(neuros screen of death ;) Circle logo with one side orange ;)

[02:40]

what does uboot console say ?

[02:41]

<crweb>

getting it one last time cleanly

[02:41]

<crweb>

i guess i have 1x sd cards.. cause.. damn

[02:42]

<crweb>

pastebin.com

[02:42]

<crweb>

heh, bad checksum

crweb: can you try using another card ?

maybe it's broken ? or updating from GUI

<crweb>

i tried MS, and SD. will try my phone SD

<crweb>

emergency flash

ah, you need to test emergency, or you just need to test if your upk is ok ?

in the latter case, please put it on an USB disk and try GUI upgrade

<crweb>

i need it to flash, so i can test my work

see if you get bad checksum when doing the GUI upgrade then

from a non-card device

[02:52]

crweb: regardin that COP thing to close settings windows when recording start (from scheduler), i think we can keep the COP thing, but actually make it a notication like recorder notifyig people that it is starting (as opposed to a specific message for main-menu to close top windows, which is silly)

[02:52]

crweb: what do you think ?

[02:55]

<crweb>

i think either you or I misunderstand

[02:55]

<crweb>

thats main-menu sending itself a cop message to close all its own windows

no, i already shot down that case. main-menu receive the RECORD key, and thus can close the settings windows without any cop at all

see mail

<crweb>

yeah, what other case is there?

however when there's a scheduled recording, main-menu doesn't know

so it can have settings open

and they will stay open

<crweb>

ah got it.

<crweb>

yes, add notifications to app starting

[02:58]

<crweb>

but, nwm can do this

[02:58]

<crweb>

on app start, send app is starting

[02:58]

<crweb>

this is common

[02:59]

<crweb>

nerochiaro: gui says bad checksum

[02:59]

hmm, i like the idea. however we may not need notification for all apps, just for some

[02:59]

in this case recording

<crweb>

then it just doesn't listen

you still waste time sending out notification that no one care about

<crweb>

but app start, main-menu should close its existing windows. we don't have room for them

<crweb>

no, it only goes to those who listen

the act of "emit" doesn't just waste resources ?

even if no one is listening

<crweb>

whos it going to send to if no one is connected?

<crweb>

no, its fine

ok then

i'll update the thread myself

<crweb>

msgs happen if no one is listening or not

<crweb>

err..

<crweb>

you get it

i get the idea, yes

<crweb>

this upk is 17.8mb but stuff can't be found?

[03:03]

<crweb>

I'm going to continue on with terry. thanks

[03:04]

unexpected (expecting ")") << this means usually that you're running an executable that it's really not an executable

[03:04]

it happens for example when i run x86 stuff on ARM or the other way around

[03:06]

<crweb>

gah..

[03:07]

crweb: doesn't app channel already have notifications for app starting ?

[03:07]

<crweb>

no, it has message sent to start app

[03:07]

<crweb>

"App starting" message would go out if app actual begins

[03:08]

so i'll tell them to add the app started in the app channel. seems the better place for it

[03:08]

<crweb>

thats what i said

[03:08]

<crweb>

yeah

[03:10]

ok, done

<crweb>

i just open sourced all my private projects

<crweb>

free hosting at code.google.com

it's been there since a long time

<crweb>

never knew..

<crweb>

uses svn too. pretty cool

shoudld use git :P

<crweb>

yes it should

and you should've known since you were a SoC mentor

<crweb>

i'm sure it will eventually

<crweb>

i didn't know they did project hosting

<crweb>

practicevision.googlecode.com

<crweb>

it is _not_ a good Qt code reference

<crweb>

i've learned much since 2005

guess so

weren't you seeling that app ?

<crweb>

no, it was privately funded

<crweb>

going to, soon as i rewrite the db layer

<crweb>

also, will be releasing topiabox

<crweb>

gui audio player for osd

[03:20]

crweb: that was pretty ugly looking ;)

[03:21]

<crweb>

topiabox?

[03:22]

<crweb>

might be ugly looking. does things xmms dreams of though

[03:22]

<crweb>

like.. multi-db sources

[03:22]

such as ?

i'm sure xmms2 does things that your app dreams of too

<crweb>

storage of metadata on removable storage

<crweb>

nothing the osd needs ;)

<crweb>

its an OSS world. of couse mine is better

<crweb>

;)

[03:24]

* nerochiaro pats crweb's ego

[03:24]

now go back to that upk issue ;)

[03:25]

<crweb>

terry and i are compiling

[03:25]

<crweb>

its not going so well though

[03:25]

<crweb>

freaking language support is still breaking everything

[03:26]

i just approved Jimmy's patch to makefiles

[03:27]

what else is wrong with these lang files ?

[03:27]

<crweb>

ah, i guess they weren't committed yet?

check it, but i guess they weren't

at least not the || exit 1 fixes

jimmy is online, be sure to check with him and get a resolution while he's still around

<crweb>

i'm pretty sure this one is from a patch i already ok'd

<crweb>

he is checking it already

[03:29]

<crweb>

qm_install error on neux

[03:29]

ok, tell him of my email of now, he may have missed it as i just sent it

[03:33]

<crweb>

if i say, wanted to go ahead and commit/submitted the parted work so you can look at it and help me. that going to be ok?

[03:33]

i don't understand

[03:33]

<crweb>

i got the external-libs/parted all setup and stuff

[03:34]

<crweb>

only thing to overcome is the compile error

[03:34]

<crweb>

want me to zip it and send it, or fix it while its in tree

[03:35]

if it doesn't break anything else except the specific thing you're working on, then feel free to commit it to tree. if it break the whole build for everyone, don't

[03:36]

<crweb>

it would have to be added to the build to do so

[03:37]

<crweb>

terry is now waiting on parted

[03:37]

<crweb>

its end of day though, so he's not waiting very badly

[03:38]

all i'm saying is: don't break the tree for everyone. if you can avoid that, feel free to commit half-working things

[03:52]

<crweb>

nerochiaro: Neuros-Cooler/external-libs/parted

[03:52]

<crweb>

make rebuild

[03:53]

i just ran an build-helper up + all

[03:53]

one minute ago. should i repeat ?

[03:53]

it seems to have picked up parted already

<crweb>

its not part of buildhelper

<crweb>

that would break build for everyone

it's part of what, then ?

<crweb>

cd Neuros-Cooler/external-libs/parted

<crweb>

make rebuild

ah, ok, just if someone forced rebuild

good

[03:56]

<crweb>

i can't get it to build, so couldn't add the binaries yet

[03:56]

it's ok then

[03:56]

<crweb>

ok.. well, please take a look when you have time

[03:57]

<crweb>

more eyes will have to fix this. cause i'm at a loss

[03:57]

ok, i will take a look later today

[03:57]

<crweb>

i disabled readline support, and it still tries to use readline support...

i'll try some cross compile mojo on it

finishing checking some big email threads, then i'll have a look

<crweb>

no problem terry's headed home for today anyway

ok

[04:25]

crweb: wow, i just checked out the changes to main-menu merge and file browser merge. good stuff there, it's really quite fast now

[04:25]

<crweb>

excellent

[04:27]

<crweb>

hopefully mine will flash and I can see too

[04:27]

<crweb>

gosh dang it

[04:27]

<crweb>

corrupt

[04:28]

should i try flashing stuff too ?

[04:29]

<crweb>

please

[04:29]

<crweb>

I seriously don't have time for this...

[04:29]

<crweb>

need to test *now*

ok, but even assuming i can flash... what does it change for you ?

<crweb>

network script startup and exec

<crweb>

support for rcU.d working

<crweb>

nfs detection in update scripts, etc

no i mean, i can flash, you can't. so what do you gain ?

[04:31]

<crweb>

the knowledge that I should format the drive and then toss the PC out the window?

ok, let me try

arizona firmware ?

right ?

<crweb>

yeah

should i turn off NFS when doing that ?

<crweb>

that dev.upk that you just created in images/

<crweb>

it will overwrite that

<crweb>

you would have to resetup your nfs settings

no problme

trying now

<crweb>

it's upgrading. warned me about not official package, but UPK checksum was ok. it's flashing it now

[04:37]

pastebin.com

[04:37]

<crweb>

mine is smaller than yours...

[04:37]

<crweb>

whats that about

also: pastebin.com

<crweb>

you flash from CF?

no, from SD

that CF message, i dunno what it has to complain

[04:39]

it's plugged in when i boot

[04:39]

regarding the size, how much smaller is yours ?

[04:40]

<crweb>

200k

[04:40]

i'm thinking i may have some lefover imedia app crap

[04:40]

<crweb>

ok.. going to rm -rf..

well, do a fresch checkout somewhere else

why removing the stuff

?

<crweb>

if it doesn't work what good is it..

[04:42]

you never know. you have terabytes of space anyway

[04:42]

:P

[04:52]

crweb: upgrade seems successful here

[04:55]

<crweb>

just for the record

[04:55]

<crweb>

when you start hearing of this issue on ML, here, and Forums

[04:56]

<crweb>

have them upgrade to latest torfu, or "run update-uboot" from uboot/serial

[04:56]

eh ? peole shouldn't need to do that

[04:56]

people

<crweb>

less than torfu 6 can't read the upk

only upgrade to latest TORFU

that's a requirement

to upgrade to AZ

<crweb>

yeah , i know

<crweb>

just remember... it'll come up

and with the new changes in upgrade we're doing now, it will be even more of a requirement

ok, i'll remember

<crweb>

someone will do it

<crweb>

i was running pre-torfu

they deserve failure if they do

<crweb>

right, but person may not realize

there are upgrade instructions...

<crweb>

we still get questions about the 3 step upgrade to torfu if they waited to long

well, ok, i'll keep this in mind

<crweb>

and it'll happen to the best of'm

it doesn't help that the version numbers are such a total mess

i keep getting confused by them

<crweb>

or in my case. the most retarded also.

<crweb>

i didn't grab my normal osd when I left home.

<crweb>

i grabbed my "traveling" bag

ah, i see

very old stuff

so now, can you flash ? was that the issue

?

<crweb>

yeah

oh very good

i'll get a sandwich and then look into that parted stuff

[05:02]

<crweb>

we should change the error to: Bad Checksum or Uboot to old to recognize file

[05:03]

to change the error, one has to have a newer uboot, so he would not have the problem...

[05:04]

<crweb>

lol

[05:04]

<crweb>

greyback: the common answer will be: upgrade to latest torfu then upgrade to AZ

<crweb>

its ok if you don't know to what I refer. you will in a few weeks

crweb: heh, I don't doubt that :)

No, I get you.

<crweb>

5 freaking hours

<crweb>

5 of them

Good luck!

<crweb>

thats how long it took to diag that problem

[05:06]

Ouch

[05:06]

it happens man, don't bash yourself over it

[05:06]

<crweb>

i grabbed an outdated osd on my way out

[05:07]

<crweb>

nerochiaro: you'd be proud though. the first time it didn't work. I automatically plugged it into a TV (last friday's issue)

[05:08]

crweb: wow, that's a step forward

[05:08]

Quick question, I notice that you don't need to source neuros-env any more. neuros-env has been moved to scripts/project-env. But it has a variable TOOLCHAIN_DIR that's not defined, so if I source it to build my own stuff, PATH gets a lil screwed up.

Have I missed something?

<crweb>

greyback: you still need neuros-evnv

greyback: why dont' you need that anymore ?
