[Redbutton-devel] subversion URL change

From: Simon K. <s.k...@er...> - 2007-06-18 16:27:36

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

	sourceforge have changed the URLs they use for subversion
access, so redbutton svn has moved from:

https://svn.sourceforge.net/svnroot/redbutton

to:

https://redbutton.svn.sourceforge.net/svnroot/redbutton

	the old URL will stop working soon (end of June I think) so if
you have a copy of the svn tree, doing "svn update" will probably not
work either.

	to fix this, you could either checkout a new version of the svn
code using the new URL, ie:

svn co https://redbutton.svn.sourceforge.net/svnroot/redbutton

	or you can run this command in the top level (ie in the
"redbutton" directory) of a tree you have already checked out:

svn switch --relocate https://svn.sourceforge.net/svnroot/redbutton
https://redbutton.svn.sourceforge.net/svnroot/redbutton

[Redbutton-devel] Small issue with BBC Teletext

From: Mario R. <mar...@go...> - 2007-05-27 20:43:39

Hi,

I just would like to report a small issue I've noticed when using redbutton.
Page 199 of the teletext of BBC ONE.

If I scroll slowly everything works ok.
If I scroll faster than the speed of repainting the list on the right,
when I stop, the corresponding list (on the right) is displayed and
then erased (like it happens when the selection is moved).

Good that after the next arrow move, the new list is displayed and stays on.

BTW, I've been using redbutton for a while and its stability has improved a lot!
Good job!

ciao

Hi,

	if you have no hard disc, you can make a ram disc like this:

mke2fs /dev/ram0

	then mount it somewhere like this:

mount -o loop /dev/ram0 /mnt/whatever

	I haven't tried different file system types to see which is
best, but given that the MHEG files are generally quite small, something
with a small block size is probably most efficient in terms of memory
usage.

	obviously you'll need ram disc support configured in your kernel
- - CONFIG_BLK_DEV_RAM et al.

	hope this helps!

if you run the browser like this:

rb-browser -d

instead of like this:

rb-browser -d services/XXXX

then the browser will start on whatever service rb-download is currently
tuned to.

at the moment, the only way to manually tell rb-download to tune to a
given service is using something like netcat to connect to the network
port rb-download listens on, eg:

nc 127.0.0.1 10101

then type:

retune XXXX

(you can type "help" if you want to see what other commands rb-browser
can send to rb-download)

Hi,

I think I had an old snapshot or a bad compilation.
Now, as you suggested "rb-download XXXX" tunes and download the
teletext information for that service and it creates the right
directory under services/

you are right again.

Basically the only problems that I have is the video. I've seen, with
"top" that redbutton uses 100% of the CPU, so I guess that this is the
problem. I will be better when you introduce the other video modes.

Is it possible to leave the rb-download running and choose the channel
from the browser? Or do I have to start them both synchronized?

Great job!

if rb-download and rb-browser are running on the same host, you should
just do

rb-downlaod 4165

then in the other window:

rb-browser -d

it should be able to tune at the beginning, you should just be able to
do:

rb-download 4165

to get BBC1 - it uses the same code as tzap to tune, so it should work!

it tries to open the frontend device read/write first, if this fails it
prints something like "you will not be able to retune", then tries to
open the frontend read-only - that should work, even if another process
is using the frontend (I can use rb-download while mythtv is running on
the same machine - I just can't retune then)

that error message doesn't look like one from rb-download

yep, the video output method I use is probably the slowest you can have,
but it does work on everything, as long as the processor can keep up! -
on my TODO list is adding things like SDL, XVideo, OpenGL, etc video
output methods, which use the graphics card more and the CPU less so
that should solve these errors

that shouldn't happen - you should get services/4165 if you do
rb-download 4165

try doing:

make clean
make

after you do an svn update to make sure everything gets rebuilt and so
is consistent.

use "scan" or whatever to generate a channels.conf file, and store it
in ~/.tzap/channels.conf

to list services on a given frequency, do either:

tzap -x "BBC ONE" && rb-download

or

dvbtune -f 722166667 -qam whatever etc && rb-download

or just grep channels.conf to find the service ID you want

to use a given service (eg 4165), do this in one terminal:

rb-download 4165

and this in another:

rb-browser -d

if you want to run rb-broswer on another host, run this on it:

rb-browser 10.0.0.1

assuming rb-download is running on IP 10.0.0.1

[Redbutton-devel] How to use RedButton

From: Mario R. <mar...@go...> - 2007-05-13 22:45:58

Hi,

I've been using red-button for a while but I'm not sure I'm using it properly.

Basically this is what I do:

1) tzap -x "BBC ONE" && rb-download
2) I read the channel id of BBC ONE (4164)
3) tzap -x "BBC ONE" && rb-download 4164

in an other window

4) rb-browser -d services/9018

Here are my questions?

1) It seems that redbutton uses channels.conf now, but if I don't use
tzap it cannot find anything. Is it able to tune at the beginning?

2) If there is alreay an application using the dvb-t card it fails
ERROR: failed opening '/dev/dvb/adapter0/frontend0' (Device or resource busy)
while i remember I used to be able to use it on the same frequency of
the already displayed channel.

3) I MUST use (-d) otherwise it behaves very bad. The video is slow or
not moving at all. And it does not respond always to the key pressed

Those are some of the warnings:
[mpeg2video @ 0xb7cf0a44]invalid cbp at 33 34
[mpeg2video @ 0xb7cf0a44]00 motion_type at 15 35
[mpeg2video @ 0xb7cf0a44]concealing 1218 DC, 1218 AC, 1218 MV errors
[mp3 @ 0xb7cf0a44]incorrect frame size
[mpeg2video @ 0xb7cf0a44]ac-tex damaged at 2 0
[mpeg2video @ 0xb7cf0a44]ac-tex damaged at 3 1
[mpeg2video @ 0xb7cf0a44]ac-tex damaged at 8 2
[mpeg2video @ 0xb7cf0a44]ac-tex damaged at 1 3

4) The only directory created under services/ is services/9018.
Reading the documentation it seems that is should have the same number
that is specified in rb-download.

Would it be possible to know what is the current preferred way of
running rb-download & rb-browser.

I forgot to say that I'm using the latest "trunk" of both applications
and latest SVN ffmpeg.

Thanks
