think I can see what the problem is - looking into this missing Resident
Program a bit more...

TODO: program TII SI_TuneIndexInfo

it looks like this should tell the browser to continue running the
current MHEG app when it retunes the video - that would explain why
there is no ~//a or ~//startup etc in the new channel - it's supposed to
keep running the current app

I've got some ideas for a patch, but it may take a while as I'm pretty
snowed under at work at the moment...

Wow, thanks for the quick reply.

I've put a couple of files on a web server: 

http://john-williams.org/rb-browser.out.gz (the browser log)

http://john-williams.org/mheg.tar.gz (services and carousels)

I tuned to BBC1 (sid 6351) and pressed the menu entry to watch some
sports. This retuned to sid 6886 which is on a different transponder.

Wireshark shows rb-browser continuously trying to download the ~//a and
~//startup files. After a few seconds it gives up and bombs out.

The log will also show that "avstream" is not working. That's OK,
because the VDR program is holding the /dev/dvb/adapter0/dvr0 file
open. I think I can fix that.

Thanks,
John Williams

sounds a bit odd, could you run rb-browser with the -v option and send
the log and/or tar up the services and carousels directory that

[Redbutton-devel] Problem after retuning with Freesat

[John W. <jo...@po...>]

Hello,

I'm trying to get the redbutton program to work with a DVB-S card and
the BBC "Freesat" service. Actually, I'm trying to convert the code
into a plugin for the VDR program.

If I tune into BBC1 and run "rb-browser" then all goes well until I
select an option from the menu that causes it to re-tune. For example,
today there's an option that causes it to re-tune to "BBC Stream 35"
which is showing a programme about folk music. This service is on a
different transponder (12441MHz instead of 10773MHz). The re-tuning
works OK and I see the new programme, but rb-browser then tries to
re-initialize and looks for ~//a or ~//startup. Neither of these exist
in the new service, so after a few seconds it gives up and exits.

There are certainly some carousel files being downloaded from the
"Stream 35" service, so I suppose rb-browser is looking for the wrong
thing, but I can't puzzle out what.

I've got a spec (mheg_profile_106.pdf), which says the initial file
object can be sent in the ServiceContextList, but the debug output
shows this is empty. There is a file "/app/a", so I tried hardcoding
this as the initial file instead of "/a"; it read the file and then
tried to find "/boot", and neither /boot nor /app/boot exist, so that
didn't work.

Any suggestions on how to debug this would be welcome, as I'm stuck.

Regards,
John Williams

[Redbutton-devel] ITV problem and channels.conf

[Nick S. <nic...@bi...>]

Hi,
I've looked at the problem with rb-download and my channels.conf file and it seems
it's only the scan-s2 version of the scan program which produces an extra entry at
the end of each line. This is a 'delivery system' code which isn't present in files
produced from the normal scan program. I've hacked the service_available function
in channels.c to look at the second to last entry and the BBC channels now work fine.
This obviously isn't a proper solution but I'll try to find out how many versions of
channels.conf exist before fixing it properly.

I still can't get the ITV channels to work either off air or from saved data and would
be interested to know if anybody in the UK can. If so it could be something specific to my region.
The recent patch in svn 535 now brings up the header page ok but the menu that normally appears
on the right is missing so no other pages are selectable. I can't find anything obvious in
the verbose output from rb-download or rb-browser except a broken link from file cr03 in
/services/8263 to a file in the carousels (it tries to link to a non existent /0/4 directory
in /carousels) but I don't know if this is relevant. Anything I can provide that would help?

Nick

I've just commited a change based on your patch that works when I do
make -j64 on a dual core machine. The Makefile is still pretty crap - it
doesn't automatically generate dependencies for a start, so I'll
probably have another look at it soon...

[Redbutton-devel] Redbutton-browser parallel makefile tweaks

[Andrew B. <b3...@gm...>]

Hello,
redbutton-browser compiles fine for me if I compile it with make -j1
but if I try 2 jobs or more it falls over itself so I asked for some help on
linuxquestions
http://www.linuxquestions.org/questions/programming-9/gnu-make-parallel-problem-846899/

The attached patch includes several fixes. Many of the object files
depend on ISO13522-MHEG-5.c, ISO13522-MHEG-5.h and clone.c but the
Makefile doesn't tell make that they do. This can be fixed with an
OBJS target like this: 

${OBJS}:	ISO13522-MHEG-5.h clone.c

make doesn't need to be called as a subprocess to compile xsd2c as long
as the Makefile knows that ISO13522-MHEG-5.h, ISO13522-MHEG-5.c and
dertest-mheg.c depend on xsd2c.
With the patch applied redbutton browser compiles fine for me with make
-j16. It still falls over itself if I try make -j64 so there is still
some work to be done, but I think this patch is a step in the right
direction.

yep that's it - there is an extra value at the end of each line in your
channels.conf file - I'll work on a patch for rb-download to ignore the
extra field in the new format - I'll also probably add some kind of
warning in case the format changes again!

glad we've finally tracked it down :-)

okay, I think I know what the problem is - do you have a channels.conf file?

if not, use the "scan" app from linuxtv.org to create the file:
~/.tzap/channels.conf

the way DVB/MPEG works is that each frequency has more than one channel
broadcast on it. Each channel has an ID number that identifies it within
the whole broadcast MPEG stream. The BBC apps work out what region you
are in by looking at what MPEG IDs are available on your transmitter.
Different regions have different IDs for BBC1, BBC2 etc - so if BBC1 is
on ID 0x104b (as it is in your case) then you are in the "S" region
("South" I guess?) - the BBC app running in rb-browser goes through all
the possible IDs asking rb-download if each one is available -
rb-download looks at the channels.conf file to work out which IDs it
knows about. So if you have no channels.conf file, as far as rb-download
is concerned no IDs are available and so the BBC app can't work out what
region you are in and so eventually it gives up with the error message
about no service being available.

If rb-download is not running, then rb-browser finds which IDs are
available by looking at the names of the directories under ./services -
basically if a directory called 4171 (the decimal value of 0x104b)
exists, then rb-browser assumes that ID 0x104b is available - and so the
BBC app finds a region and works as expected

I could patch rb-download to report that the current ID is available,
even if there is no channels.conf file - I'll look into it

if you can't generate a channels.conf file, in theory just using "BBC
ONE:4171" as a single line channels.conf should make it work, ie do:

echo "BBC ONE:4171" > ~/.tzap/channels.conf
rb-download 4171 &
rb-browser -d

by the way, rb-download used to just say that all channels were
available, but that stopped it working in Hong Kong, so this is why it
now checks what is actually available

hope this all makes sense!

[Redbutton-devel] ITV patch and tests

[Nick S. <nic...@bi...>]

Hi,
Thanks very much for the ITV patch. I've tried various freeview channels
off air with rb-download running continuously in background and seem to get
the following results:

If I start rb-browser from the same directory as rb-download as recommended:
*
rb-browser
*
SKY 3 text works well. After pressing T or R I can access all pages correctly.

ITV1/CH4 now brings up a page but I can't access any other pages either with
the arrows or number keys.

BBC channels behave as before and output the following (for BBC1):
*
Unable to load '/c/r_dls.rc'
Unable to load '/c/tv'
*
The screen remains blank and won't respond to either the R or T keys. Usually
after a delay the "The service you have requested is unavailable..." message 
appears and the program times out shortly afterwards. The program seems to go
into a loop and the cpu/IO load remains high until the program terminates.

If however I point rb-download at the relevant directory:
*
rb-download ./services/4171
*
Everything works correctly and I can access all the pages.

Unfortunately I need to read a bit about MHEG before I can understand what some 
of the code is doing. It would be useful to know if others see the same results or 
whether the BBC issue is something in my local environment.
I've saved some output from rb-browser -v but it really is pretty verbose so
all the text files are around 1MB or more. I would be happy to email them to you
if it would help. If so should I send them to the list or directly to you?
Any help/advice much appreciated.

okay, I've just commited a patch that makes ITV and C4 appear again when
you press the 'T' key - I haven't tested it against a live broadcast yet
- - only against a saved services directory - but it looks hopeful.

I can't understand why running rb-download in the background doesn't
work for you. Could you start rb-download in the background, then send
me the output from running 'rb-browser -v -d' - I may be able to see
what's going on?

[Redbutton-devel] Redbutton ITV and usage

[Nick S. <nic...@bi...>]

Hi,
Thanks very much for the information concerning ITV and CH4 broadcasts, I was afraid it was just me!
I have been leaving rb-download running whilst using the browser but it does raise another question
concerning usage. At first I was following the original instructions which don't seem to work for me even
with the BBC broadcasts:
*
rb-download 4171
Unknown PID for association tag 104
*
The carousels and services directories are created and filled with data. I leave rb-download running.
If I then start rb-browser in the same directory as follows:
*
rb-browser -d
Unable to load '/c/r_dls.rc'
Unable to load '/c/tv'
*
I can't access any pages and the browser will terminate shortly afterwards. Occasionally the "No services"
message (I'm afraid I forget the precise syntax) will appear before the program terminates.
If I point rb-browser directly at the relevant directory:
rb-browser -d ./services/4171
All is well and I can access the pages correctly.
I'm reasonably ok with C but unfortunately not  ok with mheg protocol. Anyway I'll start to look at the code
and try to learn something about how it works.
Thanks again for the help and sorry for starting a new thread. I will subscribe to the list properly in 
the future.

Hi Nick,

	you are not doing anything stupid! I've had a look and I'm getting the
same problem here on ITV and C4 - the MHEG engine in MythTV seems to
work fine on ITV and C4 so there is hope that I can work out what the
problem is - the missing files may be a red herring, ITV always has
generated errors looking for non-existant files (I think 'DNE' stands
for 'Does Not Exist'), though the missing 'cr03' link may be a clue...

	I'm going through the logs from running rb-browser with the '-v' option
at the moment - it's probably going to be some part of the spec which is
a bit vague and I've interpritted it in a different way to everyone
else, or some missing feature that hasn't been used on FreeView channels
before - I'll let you know what I find out...

	by the way, you can just leave rb-download running in the back ground
while you run rb-browser

[Redbutton-devel] Redbutton and ITV

[Nick S. <nic...@bi...>]

Hi,
First of all thanks for all the work that's clearly gone into this program.
I'm trying to use redbutton-browser to view freeview data from the Oxford
(Beckley) transmitter and am having problems with the ITV and Channel 4
broadcasts. The BBC and SKY 3 transmissions work fine. I'm using the latest svn
compiled on a Fedora 10 machine which is running both programs. Video works
in all cases but I disable it as I'm testing on a relatively slow machine.

I tune my card with tzap and start rb-download for BBC1.
*
rb-download 4171
Unknown PID for association tag 104
*
The carousels and services directories are created and filled with data.

*
rb-browser -d ./services/4171
Unable to open '/c/r_dls.rc': No such file or directory
Unknown ResidentProgram: 'SBI'
ResidentProgram params: 'true'
*
rb-browser will then display the pages correctly. This also works for
SKY 3 transmissions.

With the ITV and CH4 transmissions I seem to have a problem:
*
rb-download 8263
Unknown PID for association tag 42
*

The carousel and services directories are created and filled with data.
*
rb-browser -d ./services/8263
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open '//t/vb.png': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open 'DNE': No such file or directory
Unable to open '/nothing.png': No such file or directory
Unable to open 'DNE': No such file or directory
ObjectReference not found: ~//entrypage.asn 153
Unable to open '//cr03': No such file or directory
Unexpected EOF
DER tag
InterchangedObject
free_InterchangedObject: invalid choice (0)
Unable to load '~//'
*
rb-browser is unable to display any pages. I get the same result every time.
The //cr03 file always appears in the services/8263 directory as a broken link
to a non existent file in the carousel.
I've tried waiting for a long period before launching rb-browser in case required
data has not yet been downloaded but the result is the same. 
I tried the program about 2 years ago and I'm sure the ITV channels worked ok.
Is it possible the ITV protocol has changed or am I doing something really stupid?
Thanks for any help/advice,
Nick

Re: [Redbutton-devel] how to extract mheg5 application file?

Hi,

if you have the MHEG app on disc, then you can run rb-browser like this:

rb-browser /path/to/your/app

if you have an MPEG Transport Stream file with DSMCC data in it, then
according to this...

http://www.mail-archive.com/lin...@vg.../msg15964.html

you can create a dummy DVB device that has no physical hardware, then
you should just be able to cat the MPEG TS file into the
/dev/adaptorX/dvr0 device while you run rb-download.

I have attached a patch that another red button user - Rafael Diniz -
wrote that creates the dummy device for you

you will need to get a MPEG TS dump from somewhere

Re: [Redbutton-devel] how to extract mheg5 application file?

Hi,

	you use rb-download to download the MHEG files - if you tune your DVB
card using dvbtune and then just run rb-download with no parameters it
will list all the channels it can see on that frequency,

so something like this:

dvbtune -f 722166667 && rb-download

and you end up with something like this:

Channels on this mutiplex:

ID      Channel
==      =======
8262    ITV1
8325    ITV2
8384    Channel 4
8442    More 4
8448    E4
8642    Rabbit
8773    Heart
8452    Channel 4+1
8577    Gay Rabbit
8362    ITV2 +1
8500    FIVE

	then you can pick one channel and use rb-download to get the MHEG apps,
like this for ITV1...

dvbtune -f 722166667 && rb-download 8262

	you can add a "-v" option to get some debug messages to check it is
working.

	Either just leave it running in the background, or stop it after a
while, then if you look in the directory

services/8262/

	you should see the MHEG apps and other files that it has downloaded,
the spec says that rb-browser should try to boot apps in this order:

services/8262/a
services/8262/startup

	you can use mhegd in the redbutton author package to convert the ASN1
format apps into the text form

	hope this helps!

Hi,

	I'm not aware of any freely available GUI based authoring tools. I
can't believe people write MHEG apps by hand, so there must be some IDEs
out there, but I guess you will need to pay for them. The best Red
Button can offer is the text format compiler - if you use cpp or m4 or
another macro processor you could at least avoid having to hard
code/remember lots of object ID numbers...

	in terms of support for other countries profiles - it supports UK and
NZ at the moment - actually, the subset of the profile that Freeview in
the UK uses - I have also tested it with some example apps from Hong
Kong that someone sent me. You can also use rb-download in Australia,
but the actual apps they use are MHP not MHEG, so rb-browser won't
display them.
