great, thanks. that got it working. i had to install the development packages for openssl, libconfig, and curl for the make command to work.

i hate to keep bugging you, but there is one more thing:

with the HD stream running I am unable to navigate through the video in mpv player as i was able to with the SD stream (archived games). is that an issue with the stream itself, or is there something i can do to fix that?

thanks again

Is there a way to get closed captions with mlbviewer? I'm having trouble getting the new league video working and have to go to the old viewer to get caps and I'd love to be able to just use mlbviewer.

That may be an issue with the stream itself. Can you search this thread for "seek stream mlbhls"?

No idea. Try the SD and the HD streams and I think (?) it's the 'v' key in the video player that turns on subtitles (if present in the stream.) If they are not in the stream and somehow downloaded out-of-band, I don't have the time to look into this.

Just another quick message.

My new job is way more time intensive than it has been in prior years and leaves me with little time (or desire) for personal programming.

As long there are no architecture changes, I think I can keep up with a bug fix here or there.

But new development (or re-working mlbclassics with V3 API) is likely not going to happen until I can strike a better work-health-life balance.

Keep striving for a better balance, I wish you all the best for that! I know how important it is.

Just wanted to chime in at this point for my periodic thank-you to daftcat for all the work on taking a great application so far. I'm always kind of amazed that anybody can find the time for that level of work on a project like this, so thank you again. I hope the Python skillz you've gained through all this mlbviewer development have led to your new work situation paying you lots of money! And that with time you'll be able to both make lots of money *and* have time for personal programming projects...

Meantime, hopefully the rest of us will be able to lend a hand to help keep things running. Does anybody know if there are instructions anywhere on the best way to submit patches?

It seems that stream changes have struck us. The nexdef stream seems now to be stuck at 800kb/S and the rtmp stream doesn't work at all, as of this afternoon. They worked OK yesterday.

Hi-def using the flash plugin works OK so presumably the stream URLs have changed somewhat.

When reporting streaming issues, please indicate the game and the stream: nexdef/rtmp/speed/any other details that could spare us this turnaround delay.

I tried a couple streams and had no problems with rtmp.

You may be right about the HLS (nexdef) streams but we may be out of luck. It depends on how involved the fix may be and whether thegryghost wants to do one more fix for us or if it's time someone stepped up and took over mlbhls support.

I got no time or desire to debug this tonight. Probably not until the weekend.

If someone else wants to take a stab,

mlbplay nu=1 n=1 v=ana

That will give you a base64 string.

All those bandwidths look like garbage. That's one thing.

If you use mlbhls directly with debug enabled:

and....aha... this all works if you enable adaptive streaming because the speeds are all garbage. That was kind of an accidental discovery right now.

Code:

./mlbhls -d -B $(../mlbviewer2014/mlbplay.py nu=1 n=1 v=ana) -s 1200000 -m 1200000 -b 4800000 -o /dev/null

I'm just going to leave all of this here as debug instructions because I'm too damn tired to re-compose this tonight.

daftcat · 03-31-2016, 11:56 PM

For nexdef, change or add to your config file:

adaptive_stream=1

The nexdef stream speeds in the m3u8's (the segment playlists consumed by mlbhls) are all garbage today. Not sure if this will continue to be an issue.

Also, make sure your min_bps and max_bps allow for some garbage. I would choose the following:

min_bps=1200
max_bps=5000

This of course will make your window resize as the streams change speed so be sure to include a fullscreen option for your video player (mplayer -fs or mpv -fs.) I can't speak for vlc.

We may not get "adaptive_stream=0" (stream speed locking) back without a patch to mlbhls. I'll look more this weekend.

The RTMP streams work for me too...phew! Let's hope it stays that way (forever).

All the RTMP streams seem to be back for me on the archived games now except the 2400K one (let's hope that is true of the live games as well). Is 2400K working for you or is it just me? It it's just me, then possibly it is an issue with my stream player rather than the stream itself.

I'm a reasonably competent C and Python coder, and I actually did hack the mlbhls source a while back to have it retry failed downloads of HLS segments before giving up. If the original developer doesn't have time for it anymore, I can give it a go.

daftcat · 04-01-2016, 02:55 PM

I knew I wrote the network responses to ~/.mlb directory for a reason.

Highest rtmp speed increased to 2500 and I've made the two line change in mlbviewer code to support this.

It may be that, with the new flash viewer, adaptive speeds only are now supported with HD/nexdef. Does your Roku provide fixed speeds and if so do they still work?

According to a popup when using their old flash viewer, support for the old viewer will cease on 1 May (I am not sure what that means but presumably the adaptive streams at least will remain).
