[Redbutton-devel] [PATCH] Less strict frequency check 2

[Mario R. <mar...@go...>]

Hi actually, I think the test should be:

if (abs(frequency - target) >= 1 kHz)
... error

Which allows for 10700 Hz to be equal to 10650 Hz

[Redbutton-devel] [PATCH] Less strict frequency check

[Mario R. <mar...@go...>]

I've noticed that Kaffeine tunes a channel up to the nearest kHz, while 
scan generate a channels.conf with frequency exact to 1 Hz.
That implies that when I watch TV with Kaffeine I get this error from 
rb-download

[andrea@thinkpad tmp]$ rb-download -vv 4164

We might need to have a less strict check on the frequency, where we 
only check "frequency / 1000".

What do you think?

Re: [Redbutton-devel] Seg fault with rb-browser

Hi,

	the reason you get the error is because you cannot change
channel because you are reading your MHEG data from a local file
rather than downloading it - ie you are doing:

rb-browser services/4164/

	if you have rb-download running on the same host, you can just
do:

rb-download 4164 &
rb-browser

	and it will use rb-download to change channel - that should
stop the error and let you see BBC News Multiscreen too.

Re: [Redbutton-devel] Seg fault with rb-browser

[Mario R. <mar...@go...>]

I've tried it.
It does not crash any more, I get the error message

SI_TuneIndex: invalid service index (-1); range is 0-0

I've tried with the TV, and what happens is that

Sport -> Sport in video

sends you to page 1001, the same as the News Multiscreen, which with
redbutton I cannot access either.
I will repost my log in the same location
(http://xoomer.alice.it/enodetti/log/log.txt.bz2), just for reference.

As a side, I can report that there has been an improvement with video:

1) the video and the audio are good
2) video ratio is wrong, 4:3 instead that 19:9
3) I still get a lot of warnings: [mp3 @ 0xb7dd4c20]incorrect frame size
4) if I may, I would suggest to disable the ability to resize the
window, which gives a not too nice effect of part of the screen not
updated (in case it is made bigger)

Hi,

	thanks for the bug report - I've just commit a fix that should
stop the seg fault - revision 322.

	PS: I couldn't bunzip2 your log file when I downloaded it  - it
said the file was corrupt - but I managed to work out what was happening
from the stack trace

Hi,

	I've been doing some work on a programme to convert the MHEG5
text format into ASN1 (ie DER encoded) data - it's not ready yet, but
keep watching this space...

[Redbutton-devel] About mheg-5 authoring tools

[<qiu...@cn...>]

Hi,

As I know, there are some authoring tools of MHEG-5, such as MediaTouch, =
MHEGDitor or MHEGWriter.

But I couldn=E2=80=99t find where to get them. Anyone knows where to =
download or buy? Or any other authoring tools?

Thanks very much.

Best Regards.

Qiuhua

[Redbutton-devel] anybody can help me?

[<qiu...@cn...>]

Hi,

   Anybody can give me a mheg-5 application example with asn.1 encoding. =
You know in my country there is not any mheg-5 content broadcasted =
currently. But I installed the rb-brower and want to try to run it. If =
you can give me some more suggestions, you will be welcome.

Thanks in advance.
