 Posted: Thu Jun 02, 2005 5:06 pm Post subject: New Title: mythstreamtv for Live TV |
 |
|
I was at work today. ssh access and mythweb.
I finally got mythstream to work, just in time to watch the redsox on my desk...I went to mythweb and set the sox game to record, then I used mythstream to watch the recording.
Work reasons required me to reboot my PC, so I fire up mythstream again....I am at the beginning of the file. I couldn't seem to get the vlc http controls to work. I access the control page ate port 8002, but the controls didnt seem to work.
So I thought I could delete the recording. Then I could restart the recording and be back at real time. However I couldnt figure out how to delete the active recording via mythweb.
Any suggestions on either method of jumping ahead in almost-live tv and mythstream

There may be a better way, but in the mean time, you could try this:
http://studwww.ugent.be/~aveys/mythwifi/
I have not tried it, but it is a web interface remote control. The methods used may help you figure out how to do what you are trying.
Another option I just thought of. If you used VLC to stream the nuv file, I think the command line has transport controls. SSH in start the stream via command line, then keep the ssh window open. You can then use the transport controls there. |

odd that your web controls aren't working. I use MythstreamTV on a daily basis and have never had an issue. I just fire up mythweb in a webbrowser... which I have set on port 5190. It streams to me on port 8080 and the vlc control port is 8002 (default).
I stream to MPlayer at work. When I need to pause or reboot my work machine, I simply hit pause on the web control in mythweb's stream page. When I come back I hit the pause button again which picks up the stream where it left off, then reconnect with MPlayer.
(hitting play after hitting pause will restart the stream from the beginning... hit pause to pause and pause to unpause)
I'd be interested in seeing how ya got it streaming right off without setting a recording though

well, my php skills are beginner level at best....I will put something together over the weekend if time allows.
Be forwarned, it will be a manual install. I think I have about 15 new files and a few modifed baseline files.
Also, it is currently only configed for NTSC as the tuner needs frequency values. I looked into other sets....man, there are are alot.
That's the best thing about standards...there are so many to choose from!

EDITED 6-June-2005 EDITED
quick and dirty for now if anyone wants to play with mythstream LIVE
couple notes...
- i'm on R5A16
- requires 250 or 350
- assumes standard box (/myth/stream & /var/www/mythweb )
- I had working mythstream for recordings
- only works fo NTSC
- I'm not a PHP expert
- Code currently scrapes status.php to provide tuner status DDL for manual tuner selection
1) reconfigure and build vlc with --enable-pvr config option
2) www-data needs to be in video linux group Then restart apache.
3) untar http://www.chrismenard.com/mythstreamLive/myth_stream.tar into /myth/stream - assure reasonable pemissions
| Code: | cd /myth/stream
tar -xvf myth_stream.tar |
3b - New) edit /myth/stream/parseTunerStatus.sh - update the variable MYTH_WEB_STATUS to point to URL of mythweb status page
4) untar http://www.chrismenard.com/mythstreamLive/var_www_mythweb.tar into /var/www/mythweb (this will put files in /var/www/mythweb and in /var/www/mythweb/themes/Default
| Code: | cd /var/www/mythweb
tar -xvf var_www_mythweb.tar |
5) edit /var/www/mythweb/themes/Default/mythstreamtvLive_createfile.php and put YOUR server IP in 4 places (search for IP)
6) backup you copy of /var/www/mythweb/includes/channels.php
| Code: | | cp /var/www/mythweb/includes/channels.php /var/www/mythweb/includes/channels.php.save |
7) add this function to the bottom of channels.php before last curly bracket '}'
| Code: | function display_current_program($start_time, $end_time) {
global $Page;
$timeslots_left = num_time_slots;
$program = &$this->programs[0];
// Get a modified start/end time for this program (in case it starts/ends outside of the aloted
time
$program_starts = $program->starttime;
$program_ends = $program->endtime;
if ($program->starttime < $start_time)
$program_starts = $start_time;
if ($program->endtime > $end_time)
$program_ends = $end_time;
// Calculate the number of time slots this program gets
$length = (($program_ends - $program_starts) / timeslot_size);
$timeslots_used = ceil($length);
// Increment $start_time so we avoid putting tiny shows (ones smaller than a timeslot) into the
ir own timeslot
$start_time += $timeslots_used * timeslot_size;
$timeslots_left -= $timeslots_used;
#if ($timeslots_left > 0)
$Page->print_program(&$program, $timeslots_used, $start_time, &$this->channum);
// Cleanup is good
unset($program);
} |
 backup your copy of /var/www/mythweb/themes/Default/theme.php
| Code: | | cp /var/www/mythweb/themes/Default/theme.php /var/www/mythweb/themes/Default/theme.php.save |
9) add a link for 'Stream Live TV' to theme.php around line 164 - you'll see similar lines of code
| Code: | <a href="mythstreamtvLive.php"><?php echo 'Stream Live TV' ?></a>
| |
10) go to mytweb and try link

weird things seem to happen when the card is already recording. i got odd DVD divice errors, vlc log.txt file is full of bad requests...and ultimatly the WMP gives up and throws an error.
After I realized that /dev/ video0 was busy, I switch mythstreamtvLive.sh
to /dev/video1 and all ws well. maybe we need some tuner status smarts. At least a way to select on the device on the parameter form.

just found out that while I was testing this stuff from work today, my wife was recording a program....tonight she was watching the recording. the recording was filled with my test...it kept switching to 'random' channels
negative WAF points. telling her that 'now I can watch sox from work' didnt help any....surprizing

so far I'm not having much luck...
I've gotten the page to come up properly... I am having to make modifications to the mythstreamtvLive.sh script. You had your own IP's hardcoded in there as well as port numbers.
Will let ya know how it goes... right now it doesn't want to bind to port 8080, while my mythstreamtv will bind streams to it just fine.
will continue working on this after lunch some.
update: ok I have it working now.
I took out your internal IP addresses from the mythstreamtvLive.sh script. There is no need for IP addresses to be there.
here is my modified changes:
| Code: |
if [ $PROTOCOL = "mms" ]; then
vlc -I http --http-host=:8002 pvr:/dev/video0:norm=${FREQ_TYPE}:size=720x576:bitrate=3000000:maxbitrate=4000000:frequency=${FREQ} --sout-transcode-fps=$FPS --sout-transcode-deinterlace ":sout=#transcode{vcodec=$VCODEC,acodec=$ACODEC,vb=$VB,ab=$AB,scale=$SIZE}:std{access=mmsh,mux=asfh,url=:8080}"
elif [ $PROTOCOL = "http" ]; then
vlc -I http --http-host=:8002 pvr:/dev/video0:norm=${FREQ_TYPE}:size=720x576:bitrate=3000000:maxbitrate=4000000:frequency=${FREQ} --sout-transcode-fps=$FPS --sout-transcode-deinterlace ":sout=#transcode{vcodec=$VCODEC,acodec=$ACODEC,vb=$VB,ab=$AB,scale=$SIZE}:std{access=http{user=$HTTP_USER,pwd=$HTTP_PWD,mime=video/x-ms-asf},mux=asf,url=:8080}"
fi
if [ -f /var/tmp/STREAMSTOP ]; then
rm -f /var/tmp/STREAMSTOP
fi
vlc -I http --http-host=:8002 --sout-transcode-fps=$FPS --sout-transcode-deinterlace $1 ":sout=#transcode{vcodec=$VCODEC,acodec=$ACODEC,vb=$VB,ab=$AB,scale=$SIZE}:std{access=http{user=$HTTP_USER,pwd=$HTTP_PWD,mime=video/x-ms-asf},mux=asf,url=:8080}"
|
The thing that would be different for anyone using the script would be the port at the end of each line. That would be the port they are streaming on. The first port is the control port and does not need to be routable outside your network. So unless the port was changed from the default this should not need to be changed.
The issue I am seeing right now is that "Stop Streaming" does not actually stop the stream. I have to go to the stream recordings page and hit stop stream. Then it actually dies. I am working on that now to see why.

A little more testing.
It seems that we need a way for MythTV to actually see the tuner is in use.
The current script isn't actually talking to the backend server. It bypasses myth and is accessing the card directly. Hmmmm
That wouldn't be a big deal if Myth could at least tell that "hey something else is currently using /dev/video* atm"
So right now it requires that:
1. Nobody is actually trying to watch TV at home
&&
2. Nothing is going to record while watching TV.
There is the option of dedicating a Tuner card to this, but seems a bit much just for streaming TV.

I agree with the tuner status check. maybe a parse of the status html output. I think a drop down to select tuner is required too....maybe the drop down can be filtered to show idle tuners
my apache server is running on port 8080...so I chose 8001/2
a simple way to stop the stream would be nice too. unlike streaming a recording, livetv never ends.
If anyone in PAL land wants to play, you'll need to add your channel frequencies to the config file.

yeah I run my apache on 5190 and stream on 8080 (8001 isn't an option for me with work firewall.. had to select ports that would work)
but putting the IP in the mthstreamtvLive.sh script isn't needed.. just ":port"
one thing I saw though was that if you are streaming live TV, the backend status does not recognize that tuner 1 is "recording".
I'm gonna do a little research and see if the input to VLC can be grabbed from mythbackend itself.

I was thinking as a quick and dirty...a parse of /mythweb/status.php
check for:
| Code: | Encoder 1 is local on mythtv and is not recording.
Encoder 2 is local on mythtv and is not recording. |
and see which tuners are idle, if multiple then a quick parse of the schedule to see which tuner is scheduled to record next, then use another tuner (but, I think my usage will be during the day when little recording is scheduled):
Schedule
The next 10 shows that are scheduled for recording:
Sun 6/5 10:29 AM - Encoder 1 - TV Land - The Munsters
The Munsters (10:30 AM-11:00 AM)
The Fregosi Emerald
