HTTP stream stops intermittently #975

Closed kjeacle closed 2 years ago

kjeacle commented 2 years ago

I am using minisatip v1.2.1 to feed a MythTV server. It mostly works but perhaps 20% of recordings fail. Some channels are worse than other. The http stream starts smoothly but then at some random time during the recording, it will just stop. When this happens, attempting to connect to minisatip to join the same stream using VLC will also fail. Restarting minisatip makes everything work again.

The server is running FreeBSD but because there are no native drivers for my DVBSky S952 PCIe card, minisatip is running in a dedicated bhyve VM with 128MB RAM using Alpine Linux.

Here's some log output. Recording started at 18:00 and was due to end at 19:00 but stopped at 18:46.

I am using: -M "*:1-256" -i 32 -H 1:5 -b 752000:11550720 -B 10000, but I don't know if those options are helping. I just found them suggested while searching for solutions.

As this doesn't happen every time, it's hard to reproduce but any advice on further logging or debugging would be great. Thanks!

Hi,

Can u upload the log of minisatip by adding -f -l http arguments and also indicate the time it happens.

Thanks

Here's the full log for the extract above. Recording stopped at 18:46. recording.log

Indeed the stream stops without a reason.

I suspect a driver problem, do u have another dvb card or updated drivers?

kjeacle commented 2 years ago

I have a TeVii S480 in another MythTV box that has been working for years. I could try swapping for comparison.

Any recommendations for a new PCIe DVB-S2 twin tuner card welcome.

I have been using enigma2 boxes for years (gigablue, vu+) for years. Also had TBS cards and I know few folks are using Digital Devices.

Can't go wrong with Digital Devices 👍
