BTW, is anyone having success getting alternative audio? I'm not to sure why I'm not getting another audio other than the TV feed

Yes it works fine, apart from the fact that sometimes the radio audio is a little out of sync. Probably you are not using ffmpeg-4, or have an insufficiently recent version of streamlink.

Using "--hls-audio-select", '"*"' in your play.py? Or another method?

I do not know what you man by 'play.py' - I use mlbplay.py. Possibly you are using the wrong program. Try mlbplay.py and see if that works.

For what it is worth, my streamlink_args are
/usr/bin/ffmpeg40 is a script which starts ffmpeg-4.0, which is installed in /opt/ffmpeg40 - you don't want to interfere with your distribution's version.

There is no mlbplay.py in the current mlbstreamer package... mlbplay.py was part of the old, no longer functioning mlbviewer.

OK I see at least part of what you are doing wrong. The python script installed in /usr/bin is /usr/bin/mlbplay, not /usr/bin/mlbplay.py (my mistake on that). You should be starting /usr/bin/mlbplay, not trying to invoke play.py directly. More generally, read the README.md file in the mlbstreamer package which tells you how to set up and start the program.

You also need to set your streamlink_args in $HOME/.config/mlbstreamer/config.yaml and you need to have a ffmpeg-4.0 binary in your path or identified by the --ffmpeg-ffmpeg option, and the ffmpeg-4.0 libraries in a directory appearing in /etc/ld.so.conf or set LD_LIBRARY_PATH (which is what my /usr/bin/ffmpeg40 script does).

That's... exactly what I am already doing. There should not be a functional difference between editing the config file streamlink_args and doing it directly in play.py, which gets called by the linked binary anyway.

Either way, you're right in that adding

to config.yaml does result in a somewhat different output, however, --hls-audio-select "*" returns nothing at all but the bash prompt. But I could already get one alternate audio channel by putting it in play.py.

OK, I see one of the problems. The Spanish language radio is titled "Radio Española" in the playlist, which results in python reporting thusly

"UnicodeEncodeError: 'ascii' codec can't encode character u'\xf1' in position 108: ordinal not in range(128)"

position 108 is the ñ...

Will get you TV, radio, and natural sound.

There is a streamlink patch for this near the end of https://github.com/tonycpsu/mlbstreamer/issues/1 which doesn't seem to have found it's way into git . Or you could use python-3 instead of python-2.7. Or you could mux in only the english radio stream, which is what I do and which your subsequent posting does.

oh jeez i see people already went through everything i was discussing above. i feel pretty dumb for not checking that now.

After re-building streamlink using python3 and with the streamlink_args of

streamlink_args: -l debug --ffmpeg-ffmpeg /usr/local/bin/ffmpeg --ffmpeg-verbose --hls-audio-select "*"

I successfully got all audio channels, however,

It froze after this. Will have to look into this later

Well it was me who reported the issue. I didn't think it was your problem here, because you said that you could only receive the TV feed. If you run up against python-2.7's difficulty with unicode, you get nothing at all: it just crashes. It doesn't bother me because I am not interested in the spanish feed.

Edit: I have never tried the patch, so I cannot comment on your freeze.

Edit2: Try it without debugging enabled. That may be the cause of the problem.

Honestly after rebuilding everything to use python3 it has stopped working more or less entirely if I have any streamlink_args at all, now it just freezes. Works fine without them, though, which will have to suffice for me now.
