Yahdr - Yet another harddisk recorder, well not really :-)
Yahdr is actually a DVB device controller Application/Process which incorporates:
- A Webserver for the control interface
- s/c/t zap funcionality for tuning (only T and C for now, no other DVB cards here...)
- Another server to stream out a MPEG2-TS to client(s)
- EPG data retrieval/display (full, now/next, search)
I have different requirements/expectations :-)
No, really. I want a central machine, that
- Deals with the DVB-Hardware
- Deals with recording programs
- Deals with EPG data
- Is accessible via webserver (No OSD clutter)
I have one machine running all of the time, this machine is also my Web/Database/git and what have you server, running on a PIV/3GHz CPU w/ 1024M.
This machine should not have to cope with de/recoding or displaying MPEG streams.
Then I have my Desktop and my Laptop machine, these two a for watching TV.
I tried SQLite, but this was getting painfully slow when fed with EPG data....
News:
- Scanning is done now by simply looking at every known Channel this side of the Universe and then writing found channels/programs to the SQL database
- EPG is working...live example
- Record scheduling is working...
- 14-08-2009: You can schedule events for viewing (switch channels at given time).
- 15-08-2009: Makefile now included.
- 16-08-2009: I have to slap myself for not recognizing that message queues are the right way to pass data between two processes *slap*
(implemented now) - 21-08-2009: Threw out mpegtools an replex, since both fail to produce a proper PS. For now TS is streamed and recorded,for recordings
you can use:
mencoder -ovc copy -oac copy -of mpeg -o output.mpg -mpegopts format=dvd:tsaf <file>
to have suitable input for gopchop and the likes. - 07-01-2010: Random thougths;
I consider Yahdr stable enough to service my needs, still I'm wondering why there's no feedback from people stumbling across this Page, at all.
So, gimme some :-P -
22-01-2010: Started work on some graphics, needed for the PHP-Interface to come.
Stuffing more html/sql into the main program makes no sense, so it needs a Frontend. - 20-12-2010: Got a second DVB-C card, reason enough to start a major rewrite :-P Objective is to have n cards co-exist, so a 'super' class is needed to further abstract the different parts of the program.
- 29.12.2010: Can't get anywhere with C++ and threads, also the scanning code was pretty messy.
So I expect to have v2Yahdr ready some time in January (rewritten in plain C). - 04.01.2011: No sense in flogging a dead horse, get a new one.
Yahdr gets started, it tunes the card to the first channel it finds in the DB and waits.
You can point your Browser to http://<host>:8000/?page=channels (or whatever port you configured) to see the startpage
and go from there.
To actually watch whatever is coming out of the card just use:
$ xine http://<host>:666switching from a 4:3 Station to a 16:9 one.
(VLC opens a new window, mplayer just stops playing :-(
Maybe I should have a look at ffplay to make a usable "display only", player....)
16-08-2009: The above only applies to older versions which used mpegtools (has issues with I-frames) and (my fault :-P ) shared mem to pass data.... (ffplay,mplayer are all happy with my stream now:-) )
21-08-2009: ffplay,mplayer and xine play the TS well, as for vlc I'm probably missing a command line option....
You're invited to participate, or just have a look at the code and tell me where I'm wrong :-) .
Just git it here:
$ git clone git://gate.spitzner.org/flux/storage/repo/Yahdr or git://github.com/rasp/Yahdr.gitor browse the source Directory
There's also a Yahdr page at sourceforge with recent *tar files...
Prerequisites to compile Yahdr are libmysqlcppconn and libmysqlclient.
Find them at mysql->connectors->c++, mysql->connectors->c
To keep a better perspective of whats going on in the source I found Code::Blocks to be very useful.
It has similar features to C-Forge but is free (as in free to use, not free beer) !
