Did you update mlbviewer like I asked you to? I added some additional code to this error message which I don't see here. Can you please update to the latest revision and try again with debug enabled?

Is MLBviewer supposed to be working "out of the box" yet? Pardon my ignorance, I just want to see what the latest state of play is. I installed the lastest svn last night, then did all the requirements stuff (although both suds and rtmpdump were a bit "on the fly" as I'm still a linux newbie). I managed to get the listings screen up but when I selected an archive game (I know live games still don't work) I got a "URL not found" error. Is this currently expected behaviour? I know MLB.TV are having huge problems with their archive games. I am running Yellow Dog Linux 6.0.

Thanks for all the work on this. You have no idea how much it is appreciated (although you should do

).

That was from r164

Maybe I'm doing something wrong.

start autobahn
start mlbviewer
go to an archived game and press enter

Here'e my config

Code:

user = xxx
pass = xxx

speed = 800

video_player = mplayer -really-quiet %s
top_plays_player = mplayer -cache 800 -really-quiet -xy 2 %s > /dev/null

dvr_record_only=True
dvr_accept_policy=True
dvr_record_dir=/mnt/scambio/MLB/

Actually, live games do work out of the box now. You will need a couple things, though. First, you need a bleeding-edge copy of mplayer. Some instructions on how to do this on Ubuntu can be found here. You'll probably have to adapt them for YDL.

Next, you need autobahn.jar. Download it and run it like this: 'java -jar autobahn.jar'

It can be downloaded from here:

http://www.mlb.com/nexdef-jars/

Then run ./mlbviewer.py (NOT mlbdvr.py!)

Good luck!

Mlb.com added "duration" to the media-item element of the soap response but they didn't add it to their own schema description. This is why we are using our own copy of their schema description.

Neither mlbviewer/mlbdvr nor the test tools (soapevent/gamedayaudio/nexdef) will work without following these instructions:

Code:

1. Update to revision 166.
2. Copy the MediaService.xsd to $HOME/.mlb/
3. Remove the suds cache directory : rm -r /tmp/suds

As a special bonus, revision 166 has early test code for Highlights. These should work the same as last year. 't' key for "Top Plays" and if there is a top_plays_player in your configuration, it will use that. Otherwise, it will use your video_player (with the small caveat that I'm not supporting %f expansion for highlights yet.)

Someone was nice enough to lend me a non-premium account to do some snooping around and the results aren't good. The non-premium users are not allowed to access the swarmcast network at all so mlbviewer is pretty useless right now.

But on the whole, nexdef is nothing more than a proxy server. Sure it does some fancy stuff to smooth out playback and such but in the end, mplayer is getting an FLV via HTTP.

This is where you come in Theophile (if you want to give it a try).

Have you tried using soapevent.py to dump a game to a web server directory and then point mplayer at an HTTP url where that file is?

If this works, I'd be happy to code up a nexdef dummy that handles rtmpdump and returns a web stream to mlbviewer for mlb.tv basic and gameday audio subscribers. This way I don't have to maintain two separate but nearly identical programs or one giant if / else mess for premium and basic subscribers.

I hope this works! I won't be able to test it myself until much later tonight but you seem to be on here during my daytime.

I'm not sure I understand what you mean. soapevent.py saves a local copy using rtmpdump. Where does a webserver come in?

Using soapevent.py, dump the file to a directory in your apache path

Code:

# cp soapevent.py /var/www
# cd /var/www
# ./soapevent.py 14-244356-2009-04-18

While that's happening, start mplayer as:

Code:

mplayer -autosync 30 -cache 8192 http://127.0.0.1/14-244356-2009-04-18.mp4

(I find autosync does help a little in getting the video and audio synced up.)

I'm wondering if mplayer will perform the necessary flow control to keep itself from choking on more stream then it absolutely needs.

The thought here is that if this works, then I can write a dummy web-server that performs the rtmpdump code on the back-end and serves up the media file to mplayer on a web stream. It's a bit klugey but it would be a reasonable mimic of what nexdef does so that a lot fewer lines of mlbviewer would have to change to support mlb.tv basic and gameday audio subscribers.

I swear Sidney Ponson is our Brett Tomko this year. I'm glad to see Banny is back and Hor Ram is out of the rotation. Now we need to bring Hochevar back and send Ponson packing to anywhere but here.

sruchris · 04-21-2009, 07:25 PM

Do I need to install autobahn.jar for Gameday audio? I ask becasue when I select a game using mlbdvr.py, I get:

An error occured locating the game stream. Uncaught error.

When I try mlbviewer.py, I get:

An error occured locating the game stream. No stream available.

Any ideas? Keep up the good work!

Here's what I get in the log:

Is this all there was in the log?

First, if you haven't already, upgrade to SVN revision 166, install the new MediaService.xsd, and remove the suds cache. This step is mandatory for everyone because mlb.com changed their schema definition (They also haven't fixed their errors in their schema definition so we're using a modified copy of their definition.)

Code:

$ cp MediaService.xsd ~/.mlb
$ rm -r /tmp/suds

If you've already done this, then I need the full output of the suds error. You can get that with

Code:

$ test/gamedayaudio.py 14-244395-2009-04-21 | tee suds-error.log

Now, gamedayaudio.py doesn't do stream selection and audio follow like mlbdvr.py does. If you're hooked on a particular broadcast team, I suggest using mlbdvr.py once you've got the suds errors worked out.

Gameday audio doesn't use nexdef so mlbviewer is useless for 2009 audio at the moment. I'm looking into different ways to bridge the gap. It's getting really annoying that I can't have all the pieces working in a single solution like last year.

geesh i logged in 2 or 3 times and got the "sign-on restriction error"

Can ANYBODY actually TELL ME what the exact rules are for signing on? or does mlb just decide on a whim if you've been logging in too much? If I knew the exact limit I would know what not to do. It's one thing to get banned when there's no games on, but when there's live games going on... grrr

also, I set the max_bps to 3000000, yet i wasn't getting the top-tier stream like i was before. anyone else notice that?

sruchris · 04-21-2009, 08:05 PM

Thanks for the quick reply daftcat. After following your directions I now get this error when I select a game using mlbdvr.py:

An error occured locating the game stream.
Sign-on Restriction Error.

Here's the very last bit of the output of

$ test/gamedayaudio.py 14-244395-2009-04-21 | tee suds-error.log
