Hi all,
I still have a problem with my new setup: * Raspberry Pi B (256MB system + 256MB video) * MLD 5.0.0 testing distribution (http://www.minidvblinux.de/) on a 4GB class 6 SD card, using VDR 2.2.0.203-207 * vdr-plugin-rpihddevice (from MLD 1:2015.08.24-37+2.2.0.203) * Octopus Net (firmware 1.0.55) : Linux VLC shows TV channels without problems * vdr-plugin-satip (from MLD 2015.09.19-20+2.2.0.203) * recordings on an NFS share (works for playing, didn't test recording) * the Raspberry is powered from one of the 5V output from the Octopus, which provides enough power for the CI interface, which seems
Playing live TV works great, until some point a few dozen minutes later, where some errors start to appear in /var/log/messages:
Oct 25 10:51:59 vdrpi user.err vdr: [17414] ERROR: 1 ring buffer overflow (940 bytes dropped) Oct 25 10:52:01 vdrpi user.info vdr: [17414] SATIP: Detected 1 RTP packet errors [device 0] Oct 25 10:52:05 vdrpi user.err vdr: [17414] ERROR: 496 ring buffer overflows (652736 bytes dropped) Oct 25 10:52:11 vdrpi user.err vdr: [17414] ERROR: 584 ring buffer overflows (768544 bytes dropped) Oct 25 10:52:17 vdrpi user.err vdr: [17414] ERROR: 584 ring buffer overflows (768544 bytes dropped) Oct 25 10:52:23 vdrpi user.err vdr: [17414] ERROR: 580 ring buffer overflows (763280 bytes dropped) Oct 25 10:52:28 vdrpi user.err vdr: [17413] rpihddevice: [libav] Header missing Oct 25 10:52:28 vdrpi user.err vdr: [17413] rpihddevice: failed to decode audio frame!

Some earlier errors were:
Oct 24 18:02:59 (none) user.err vdr: [11447] SATIP-ERROR: Connection timeout - retuning [device 1] Oct 24 18:03:00 (none) user.err vdr: [11442] ERROR: 584 ring buffer overflows (768544 bytes dropped) Oct 24 18:03:04 (none) user.err vdr: [11447] SATIP-ERROR: Connection timeout - retuning [device 1] Oct 24 18:03:06 (none) user.err vdr: [11442] ERROR: 584 ring buffer overflows (768544 bytes dropped)
Those errors lasted for hours, until I stopped VDR. It's usually not fixed until I power cycle the pi.
I don't know were to look from here. Options are: * the satip plugin may not be the latest one (but the version number is unclear and the MLD forum is all german-speaking, which is a problem for me) * the ethernet interface may miss packets even though it does not report any packet loss (I changed the cable -quality and length- without success) * the power provided to the rpi may be enough, but I don't know about temperatures (the video core reports 54°C, but the ethernet chip may be too hot) * maybe the Octopus does not provide a proper stream, or the problem comes from the VDR core or the rpihddevice output...
Since I'm new to rpihddevice, satip and MLD, and didn't stress previous Raspberry Pïs before, even though I use VDR since a dozen years at least, I'm really lost here.
Latest test: a few second after switching some channel, the image froze, sound looped, and the pi was not reachable anymore through SSH, even though the octopus still reported the live stream and the network LEDs on the pi was still blinking. Hardware problem, network driver problem ?
TIA,
