Me TV

hot-keys - numbering of channel-list?

Asked by Timf

Hi Michael,
1).
The addition of hot-keys is excellent.
However, using PAGEUP/PAGEDOWN obviously only allows you to change channels one at a time.

Once the channels.conf is displayed, along with the EPG, if each channel was allocated a number,
(eg like as in Kaffeine), one could use the number keys to jump to any channel, instead of having to
"scroll" via PAGEUP/PAGEDOWN keys. If a user had very many channels, this could be laborious;
but with a numbering scheme, much quicker.

As an extra, for remote controls, once a tv card has it's remote control working via evdev, ie as a keyboard,
a user can use the remote control to operate your hot-keys. I simply altered my key-codes for CHANNELUP and
CHANNELDOWN to PAGEUP and PAGEDOWN; ZOOM to F; INFO to E; and I can now use my remote control with Me-TV.

If the Numbering scheme could be implemented, simple remote control access would be achieved!

Any chance?

2).
Your advice on the list to enable using 2 tuners works:
Create an me-tv2.config, with the different lines:

<add key="dvr_path" value="/dev/dvb/adapter1/dvr0"/>
<add key="demux_path" value="/dev/dvb/adapter1/demux0"/>
<add key="frontend_path" value="/dev/dvb/adapter1/frontend0"/>

enables one to use Me-TV on the 2nd tuner. I must, however, use a different app to access the 1st tuner.
(I can't run Me-TV twice in ubuntu - the 2nd instance will open, but it freezes - something to do with the sound system)

Again it's a terrific app - well done!

Regards,
Timf

1). You should raise that as a blueprint. I think it's not a bad idea.
2). Are you using the -c option? Try changing the "audio_driver" setting in one of the config files to "alsa", "oss" or "esd".

I haven't tried that before, I'll have a go.
I have coding experience, but none in Glade.

2).
I just place this file on to the desktop, and run it in a terminal:

#!/bin/sh
me-tv -c /home/timf/.me-tv/me-tv2.config

Do you mean this?

<add key="xine.audio_driver" value="auto"/>

Yes, "xine.audio_driver", change that one.

 Hi Michael,

Doing this in both me-tv.config and me-tv2.config:

<add key="xine.video_driver" value="auto"/>
<add key="xine.audio_driver" value="alsa"/>

worked fine in ubuntu gutsy 7.10
Both instances of me-tv work great. (me-tv in gutsy stuck at 5.27)

In ubuntu hardy 8.04, if I use alsa for all xine sound (no pulseaudio on
any),
I can use kaffeine on one tuner, and me-tv on another tuner,
and all works great in 8.04.

But in ubuntu hardy 8.04, using two instances of me-tv,
with all alsa, sound is ok,
but now the video in both instances of me-tv chop up badly to lots of green.

The only other option for video I can see is "xshm", however
this makes no difference.

What should I try?

Regards,
Timf

 Correction! Using the latest drivers from Linuxtv.org, the same problem
occurs
in ubuntu 7.10 and ubuntu 8.04.
(Need to use these drivers to obtain working cards; in 8.04, need to
rm -rf /lib/modules/.../ubuntu/media/saa7134 and cx88 first before
compiling)

Are you using different "xine.fifo_path" settings? They will definitely conflict if they use the same path.

 Brilliant! OK - created a 2nd called video2.fifo
and we are set - 2 running me-tv's on 2 tuners! (On 8.04)

Many thanks!

Make sure that you check Me TV 0.6 when it's done. It will support multiple tuners.

 OK, sorry to be a bother.
ESD turned off (infamous for causing A/V sync problems).
With xine.audio_driver" value="alsa" in both
- bad A/V sync problem in both, can play both

With xine.audio_driver" value="auto" in one, xine.audio_driver"
value="alsa" in 2nd
- no A/V sync problem, won't load 2nd

With xine.audio_driver" value="auto" in both,
- no A/V sync problem, can only load one a time or Green choppy video,
choppy audio in both

Don't know anyhting about this new Pulseaudio.

Do you know of anywhere in xine config where A/V sync can be managed?

Hi Tim,

You might need to up the number of xine video buffers. Depending on which version of Me TV you have, you change it in the xine.config or the me-tv.config.

Thanks,

Michael

 OK. Should have thought of that!

 From Question 25644 from Dale,

I'm trying his:

.version:2
engine.buffers.audio_num_buffers:1024
engine.buffers.video_num_buffers:2048

which seems like a good scheme.

(I am presuming these numbers are kilobytes?)

I need to do a little investigating, as the blurb for 8.04 was about the
new sound system Pulseaudio, supposedly to replace ESD,
but it seems to default install ESD anyway.

I had this turned off, in preferences->sound but I may have
inadvertently turned off Pulseaudio (It's marked ESD!).

The A/V sync problem improved dramatically by turning "ESD" on, and
using ALSA, not auto in both instances (this not work in 7.10 or debian
lenny).
However, with testing, after a few hours, just using one instance, the
whole system froze to a still picture, had to power cycle.

So this solution with xine.config may solve that as well.
Fingers crossed!
