any ideas?

install macports and use the rtmpdump from that... works perfectly with no patching

Noob here!

Sorry everyone... I JUST installed ubuntu and I heard that there is a great amount of support so I thought that I would ask to see if I could get some help....

I have been looking through the forums trying to get some help on what I need to do to get my MLB.TV to work and I have gotten to the point where I get it going and all that I see is it "transferring data from gdx.mlb.com" for almost 10 minutes now.

Is this because of linux or mlb.com?

ANY help would be appreciated... I'll keep searching the forum for help... if someone wants to walk me through on Empathy send me a message and I can connect with ya... THANKS

You're talking about the Flash player, right? In my experience, even when the Flash player is working properly, the status bar always says "transferring data from gdx.mlb.com". Are you sure you have Adobe Flash Player installed on your system?

Personally, I think you'd be better off using mlbviewer rather than Flash.

Daftcat-
Can you say what the current state of the Nexdef mlbviewer is? What can I do to help?

Thanks for your hard work!

Current state: meh!

It's buggy at best when it works at all even against the official flash player. I can't get anything except the describe url to show up in either Firebug or the new HTTPFox extension. Initial testing shows the control url may not be supported at all. Without the control url, stream selection won't work like last year. Innings support may work like last year.

On top of that, I'm getting stack traces from the plugin that I plan to share, along with my notes from what I've observed last year and this year with my contact. I'm not sure it's entirely stable in the official builds yet. I'd also like to get some implementation details/differences between last year and this year.

I also hear that boxee has implemented HD but doesn't require the nexdef plugin. I wonder if this means they've implemented their own Apple Live Streaming client code. If so, I wonder how hard it would be to copy their implementation for us. I'm going to try to wade through the boxee code over the next couple of nights to see how they are doing it.

One way you could help is if you can download either Firebug or HTTPFox and try to capture the local.swarmcast.net traffic using the flash player. Also, if you know your way around Boxee source, I could use some help on that front too. So far, I haven't been able to find where the MLBtv plugin is.

My best guess is that NexDef might not be available in mlbviewer until the end of the month. This should also give MLB.TV some time to work through any April jitters that happen every year.

I found the mlb app at .boxee/UserData/apps/mlb

Looks like it's byte-compiled. Don't know if you can decompile python easily.

Thanks again for all the hard work daftcat.

I installed Boxee to see how it performed. I don't watch television other than a news cast or special every now and then, but for mlb what I found is for me at least it had to pause every 70 seconds or so (high quality mode) and readjust to the stream or something. I have cable for my internet service with something like 20 megs down, so I don't think thats the problem. It did make it impossible for me to continue to watch though, so I switched over to mlbviewer and all was good except I still haven't got my sound working. Mlbviewer is definitely the best choice for watching mlb in my view.

Boxee is very cool though.

I haven't used Boxee in a while but if they did it like they did other online streaming, all they do is capture and scale the output from the Flash plugin. This is why if you look through the Boxee support forum for issues relating to the MLB.TV app, you see problems with flash overlays not going away and the like.

While this is better than nothing, the rtmpdump method is way better than this.

How come you don't have sound yet? The audio codec is AAC which is provided by (I believe) the faad libraries. Probably best to download the source from http://www.audiocoding.com. Build this, then rebuild mplayer.

Okay, can you use soapevent.py to download about 15 seconds of a game? Then play it with mplayer using none of the "quiet" options and tee the output to a file, e.g.

Code:

$ test/soapevent.py 14-263916-2010-04-13

(Ctrl-C this after about 10 seconds.)

$ mplayer 14-263916-2010-04-13.mp4 | tee /tmp/mplayer-command-output.log

(Quit this as soon as the timer starts running so we don't get pages of timer output.)

Then post that output to pastebin.com and post the pastebin url here. Either myself or Theophile can figure out what's still not working.

rjwood,

Can you use mplayer to play other types of files with audio? If so, could you paste us a similar output from a file with working sound?

What I see indicates that mplayer is handing the AAC just fine, but for some reason it is having trouble finding a suitable output driver. Kind of like the problem we just fixed with the video, only with sound this time. Fun, right?

daftcat · 04-14-2010, 05:45 PM

rjwood,

Also, can you do:

Code:

$ mplayer -ao help

I'd be surprised if 'oss' doesn't work so you could also try:

Code:

$ mplayer -ao oss 14-263916-2010-04-13.mp4

hey all,

i'm having trouble with my mlbviewer on my snow leopard netbook (dell mini9)

I've got everything running, but when I try to play a game I'm stuck with this:

Buffering streamRTMPDump v2.2
(c) 2010 Andrej Stepanchuk, Howard Chu, The Flvstreamer Team; license: GPL
Connecting ...
MPlayer UNKNOWN-4.2.1 (C) 2000-2009 MPlayer Team
141 audio & 304 video codecs
Playing -.
Reading from stdin...
'Starting Live Stream

and thats as far as it will go, it sits there for a minute than goes back to mlbviewer

using the soapevent command daftcat just posted, I can make an mp4 and watch it with mplayer!

I can also watch games with the stdout.py tool, so Its probably something in my mlbviewer config somewhere, but i cant figure out what...

any ideas?

EDIT: seems to be working with live games... sweet! definately the only way to watch mlb.tv on a netbook!
