Hi.  I have tried BS player as well.  I don't think it's the player as it's
getting a "taking too long to read" error in backend log.  As for latest
fixes, I'm only using the latest version in arch repo, mythtv 1:0.25.2-1 and
tbh I don't really fancy compiling a newer version as it took me a while to
get it all working after the switch to systemd :) 
Playing videos works so I know the players are working at least.  Just that
'taking too long' error and it trying to access a zero byte file instead of
the actual stream is making me wonder if I can get around this.

Dean, 

Try out the BS Player.  We have had most success with that player.

I am hoping the built in player gets better.

Also, make sure you are running the latest fixes.  There was an issue a
while back where HLS wasn't working, but is fixed now.  Make sure it is up
to date.

BTW, are you running the apk we provide, or are you running right from the
code?

I am hoping to put a new download out soon as we have made some great
strides on other functionality inside the app.

Thanks,
Dan

Hi, wondering if you could help clear something up for me.  I've got mythtv
0.25 running on my arch system, all working great and other frontends
connecting fine.  Got the droid app and it connects to the backend ok,
receives channel list ok but when I launch the channel, either in internal
viewer or MX player it fails.  Now looking at the logs on the backend it
seems it's trying to read the 0 byte file that gets made on initial channel
selection.  Here's the log

1001_20120820193551.mpg is the 0 bytes file, and 1001_20120820193552.mpg is
the actual stream but it's not trying for it.  Do you know something about
this that can help me?  

Thank you

DW

Check that the stream is being created: http://your_backend_ip:6544/ 

Click API -> Examples -> HTTP Live Streaming

Make sure there is an entry getting created and it is processing a live
transcode.

Right, I went to the url and installed jw player, and then accessed a
channel with the android app and looking in the livetv folder there is the
usual zero byte file and then the stream file appears not long after.  It
doesnt appear in the live streaming list until I goto select livetv from the
drop down and list files, then select the mpg and Add Stream, which then
(after I refresh the page a few times) shows me the stream I can click on
and play, and also there are a LOT of small ts files being made in the
recordings folder.  I guess they are to stream to the android?  They are
named like 1072_20120821132706.mpg.480x272_800kV_64kA.ao_32kA.000027.  well
anyway it's still not working :(

Dean, 

The files you are seeing are correct.  The live transcode creates multiple
small chunk files of the recordings.  Then they are added to a .m3u8
playlist, which is streamed to MythTV for Android, or the JWPlayer, etc.

When was the last time that you updated the backend.  There was an issue a
few months back where HLS was starting, but no stream was coming out.  It is
fixed now in the source.  If you haven't updated in a while, then I believe
this is the issue you are seeing.

Version        : 1:0.25.2-1, just what is available in the arch repo.  I
think I'll just hang out for an update, I don't need the streaming function
right away anyway.

Last updated 18th July according to the database.  Is that with fixes you
reckon or not?  If that is with fixes then I've no idea what is wrong. 

How does one get to live TV via the android app?  Is this functionality that
is in the packaged version that does not yet exist in the source repository?
