MLB.TV in Linux

fang2415 · 03-26-2012, 09:47 PM

Okay, just reproduced the sign-on restriction one more time before bed. Did the same as last time with the same result (although this time I didn't wait for the files to start downloading but just hit q as soon as mlbviewer displayed the player command). I backed up the cookie file after each attempt and they're all the same. I don't see any sessionkey or any other session-looking files anywhere at any point.

That's all for me today, I'll probably have some time to test again tomorrow so just let me know if there's something you'd like me to check.

Are you reusing the ipid, fprt, and ftmu cookies? From my testing, you only need to get those once via the login/workflow url's and they will have an expire time associated with them (in epoch time). As long as the expire time is still valid, you don't need to login or fetch the workflow url, you only need to fetch the "findUserVerifiedEvent" URL with the cookie data. It's been my experience that fetching the workflow URL too many times will cause the sign-on restrictions. The cookies can be saved to disk and reused between stops/starts of MLBViewer. Also, creating a base64 url cache (keyed off the event and content ID's) would probably help reduce the amount calls to mlb.tv.

I encountered certificate errors when trying to use mlbhls under cygwin.

You can check to see whether you will also encounter certificate errors by trying the following command:

Code:

mlbhls -B `./mlbplay j=03/26/12 nu=1 n=1 v=phi` -o game.mp4

Let that run for a few minutes and see if game.mp4 is increasing in size and mplayer can play it.

If you run into certificate errors of the form:

error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while

Only hit the login/workflow page once at mlbviewer start-up. From that, I keep all the cookie information and re-use it. I'm not sure whether I re-use it from one start to the next. I plan on creating a test tool just to inspect the cookie use and re-use without having to go through the curses interface that I can liberally print to the screen to see just how I'm managing those morsels from one request and one session to the next.

As I said earlier, I requested the same stream at least six times in a row (quitting before it actually started streaming) and was not able to reproduce it.

If not, search through cygwin's include directory and see where they define it, I can add a #ifdef to include it if it's somewhere else.

Thanks for the quick reply folks, i really appreciate it.

I got the latest version, i now get the following error:

Code:

$ make
gcc -O2 mlb.c utils.c output.c -lm -lcrypto -lpthread -lconfig -lcurl -o mlbhls
/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../i686-pc-cygwin/bin/ld: cannot find -lconfig
collect2: ld returned 1 exit status
Makefile:11: recipe for target `mlb' failed
make: *** [mlb] Error 1

I think I need to work out what library I am missing in cygwin based on the -lconfig flag. I am not familiar with this and will have a google on this. Anyone know what cygwin library I would need to fix this?

Thanks

Thanks daftcat, i will try this out once I get the mlbhls compiled

-lconfig comes from libconfig

Looks like I downloaded and built it from source from here:
http://freecode.com/projects/plibconfig

again thanks for help, I think i installed this correct, I downloaded extracted to location of my choice (/usr/src/libconfig-0.2.6) then installed as per INSTALL doc:

Code:

./configure
make
make install

Installed ok no error. Im not sure if I have to copy any dll or .h files from this location elsewhere? Anyhow when I try to compile mlbhls again, it gives different errors which indicate to me that mlb.c cant find a particular #include .h file or some other library that contains definitions for these structs/variables?

Code:

$ make
gcc -O2 mlb.c utils.c output.c -lm -lcrypto -lpthread -lconfig -lcurl -o mlbhls
mlb.c: In function ‘get_opts’:
mlb.c:1284:6: error: ‘config_t’ undeclared (first use in this function)
mlb.c:1284:6: note: each undeclared identifier is reported only once for each function it appears in
mlb.c:1284:15: error: expected ‘;’ before ‘cfg’
mlb.c:1285:6: error: ‘config_setting_t’ undeclared (first use in this function)
mlb.c:1285:24: error: ‘setting’ undeclared (first use in this function)

My mistake. Looks like there's (at least) two (three?) different packages called libconfig. I had two but found the one that had config_setting_t defined in it.

Code:

http://libconfig.sourcearchive.com/downloads/1.3.2-2/libconfig_1.3.2.orig.tar.gz

http://libconfig.sourcearchive.com/d....2.orig.tar.gz

See if you can just build this and install it over the wrong one I gave you. Otherwise, we might have to do some surgery on your cygwin to repair my mistake. Sorry about that. Looks like I have a README-cygwin to write.

nah no mistake from you, it wasnt working in the first place, i am grateful for the help.

I didnt realise that I installed to a different directory, the install was successful but now I get this error:

Code:

Josh@JOSHUA /usr/src/mlbhls
$ make clean
rm -f *.o mlbhls

Josh@JOSHUA /usr/src/mlbhls
$ make
gcc -O2 mlb.c utils.c output.c -lm -lcrypto -lpthread -lconfig -lcurl -o mlbhls
/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../i686-pc-cygwin/bin/ld: cannot find -lconfig
collect2: ld returned 1 exit status
Makefile:11: recipe for target `mlb' failed
make: *** [mlb] Error 1

I removed the directory where i installed the first incorrect lbconfig but still get the same error as above?

daftcat · 03-27-2012, 05:16 AM

You're back to square one. The linker can't find libconfig. I gave you a link to the wrong libconfig the first time. It found "libconfig" (-lconfig) but none of the symbols in that library made sense (e.g. couldn't find config_setting_t for example and so it threw different errors.) Make sure you download and build and install the 1.3.2-2 libconfig from above.

No, I haven't used the flashplayer for about two weeks. It's gpu acceleration is poor compared with what mplayer or vlc provide, and I don't watch much pre-season anyway.

It looks as if MLB.TV has some additional heuristics on how it detects an excessive number of accesses to its streams. However your new login works much better than the old one. mlbviewer is set up to work really well this season, for which many thanks.

I am using libconfig-1.4.8. It works fine for me. You can get the tarball from http://www.hyperrealm.com/libconfig/

I recommended the version I did because I know that is one I already have working on my cygwin system. Unfortunately, I forgot that I had already made the wrong "libconfig" error before and posted before I checked what actually works. Looking at the C API on hyperrealm, this looks like the correct libconfig.

I noticed that although I retrieve all the cookie information I need in the MLBSession class and pass all the morsels necessary to the GameStream class, I may not actually be making media requests with the cookies present in the request. I modified the code to pass the cookie_jar along with the cookies to the GameStream class and the GameStream class installs the cookie_jar so that it presumably passes the cookie to the server as part of all media requests.

Again, since I am having trouble reproducing sign-on restriction errors, this fix may or may not do anything helpful. When I get home tonight, I'll check it with a sniffer to see if it makes any difference in the requests being sent.

In the meantime, I've checked it in and the two of you receiving sign-on restriction errors can test it out to see if it helps any.
