RTMP stream hangs after a day of playback

[lukasmican]

Hello,
I am using omxplayer to play RTMP stream to HDMI TV. It is supposed to play the stream for weeks or even months without stopping, but after a day the playback stopped and the image on screen looked like the video was paused. Values in stats were strange too. Normaly stats look like this:
M:233595403 V: 0.62s 0k/ 4800k A: 0.62 0.43s/ 6.07s Cv: 0k Ca: 0k
But after the playback stopped, the stats looked like this:
M:15673529318 V:4196039.50s 4800k/ 4800k A:4196037.00 4196036.50s/ 6.07s Cv: 10236k Ca: 1607k M:15673699136 V:4196039.00s 4800k/ 4800k A:4196037.00 4196036.50s/ 6.07s Cv: 10236k Ca: 1607k M:15673870192 V:4196039.00s 4800k/ 4800k A:4196036.50 4196036.50s/ 6.07s Cv: 10236k Ca: 1607k M:15674038372 V:4196038.50s 4800k/ 4800k A:4196036.50 4196036.00s/ 6.07s Cv: 10236k Ca: 1607k M:15674207351 V:4196038.50s 4800k/ 4800k A:4196036.50 4196036.00s/ 6.07s Cv: 10236k Ca: 1607k M:15674378944 V:4196038.50s 4800k/ 4800k A:4196036.00 4196036.00s/ 6.07s Cv: 10236k Ca: 1607k M:15674549517 V:4196038.00s 4800k/ 4800k A:4196036.00 4196035.50s/ 6.07s Cv: 10236k Ca: 1607k M:15674719479 V:4196038.00s 4800k/ 4800k A:4196036.00 4196035.50s/ 6.07s Cv: 10236k Ca: 1607k M:15674888066 V:4196038.00s 4800k/ 4800k A:4196035.50 4196035.50s/ 6.07s Cv: 10236k Ca: 1607k M:15675057536 V:4196037.50s 4800k/ 4800k A:4196035.50 4196035.00s/ 6.07s Cv: 10236k Ca: 1607k M:15675227744 V:4196037.50s 4800k/ 4800k A:4196035.50 4196035.00s/ 6.07s Cv: 10236k Ca: 1607k M:15675396418 V:4196037.50s 4800k/ 4800k A:4196035.00 4196035.00s/ 6.07s Cv: 10236k Ca: 1607k M:15675565314 V:4196037.00s 4800k/ 4800k A:4196035.00 4196034.50s/ 6.07s Cv: 10236k Ca: 1607k
How can I play the stream for weeks without stopping?

Thank you

as a workaround: Can't you setup a cron job to restart omxplayer periodically?

Additionaly: Does it hang or does it crash?

Br,

I have set up a simple watchdog that restarts the player process if network activity is low. This is just a temporary solution, because the restart results in 10 sec of black screen. The playback is publicly visible, so any black screens or lags are not desired.

When the playback hangs, the video on screen freezes, but stats on command line continue normally, except for the strange values (as posted in my inital post).

I think the stats you see after the screen freezes mean that your buffers are full.

So, it seems there's something wrong at the end of the chain (bmc driver bug?)
