Re: [Dvr-devel]dvr wishlist

Hello Dag B,

Jingle bells, jingle bells, ... la la la lere

Yes it is almost christmas.

I like this sort of whishlist, clean and smart.
So have a closer look at it :

What do you mean exactly by "append-name" ?

Good news, I am actually working at this feature. In fact I am thinking at 
what I should do :
- a GUI with completely detached "recording core" (a sort of frontend), with 
the ability to edit a sort of cron. 
- a GUI with integrated "recording core", and another command line tool with 
a cron

I am also working at that :-) But it is not as easy as it may seem, due to 
the V4L layer. This is, with avifile, the only obscure part of DVR :-(. It is 
taken from kwintv and I have to rewritte it myself.
However I love to have CLI tools, as they are almost fully independent of any 
strange things. And work is in progress.

Hum... I don't know much about mp1e. I would need help and too much time for 
that. But why do you prefer mp1e to Divx, or Indeo ?

Subtitles can be stored in a ".sub" file and read later by an AVI player I 
think.

Why ?

Perhaps. Xawtv is my prefered TV software, however it is not really important 
for the moment. I put it on my TODO list and we'll see later.

It is easy to add 32k. I'll do it soon. Check CVS tomorrow.


I would really like to work at all these things. Unfortunately I have to work 
to earn my life, and I don't have much time left. So be patient please...

BR,
