HDR-FOX T2 to HDHomeRun, my journey

I did try recording connecting a network cable, I was able to record four simultaneous HD recording and there were no video problems in any of them :doublethumbsup:
1638560377757.png

But later after 10pm the network cable fell out 22:16:14! :(
DvrOnTime stopped the recordings and terminated the service 22:17:12.
The service restarted about a minute later 22:18:25 and resumed the recordings 22:18:35.
This is much better than the Humax which loses schedule information as soon as the recording starts so doesn't resume recordings after a restart,

However rather terminating the service following a network problem I would have expected DvrOnTime to start periodic polling to find an active HomeRun box on the network to minimise gaps in the recording.

I did try recording connecting a network cable, I was able to record four simultaneous HD recording and there were no video problems in any of them :doublethumbsup:
Good news! I'm still touching wood but no recording errors wired here too, and I've done loads, mostly in HD.

But later after 10pm the network cable fell out 22:16:14! :(
Broken off retaining clip...? I assume you were using at the time and shoved it straight back in then!

However rather terminating the service following a network problem I would have expected DvrOnTime to start periodic polling to find an active HomeRun box on the network to minimise gaps in the recording.
Yes that would seem logical, I don't see why it should have terminated. At some point (delayed due to lack of ports) I'll add my 2nd HomeRun Quatro to the network and would then be able to test a failover mechanism if @lc200 decides to include it. When it does resume the recording does append to the same file it had already started or create a new file? Hopefully the former which is what Sky boxes do if the signal is lost.

Of course. And you take the easy option as you can't bear to throw away an otherwise perfectly good cable just for that, although you really know you have to. I'm sure we've all been there. Those ones with the boot round the plug are just a different type of annoyance when you can't release the latch.

Yes, yes but it would have picked up wireless if left alone

It creates a new recording with 1 in name after the date eg ITV News at Ten 02-12-2021 1 S0E0.ts
I would prefer recording start time

Thanks for info and feedback. Honestly I haven't really tested or worried too much about the network failing so it's not been coded as robustly as it could in this regard. I've been using my own software for recording since October 2019 and never had the network fail so its not been something I've really worried about.

I think the way it is coded it will try and start recording again by calling out on the network for any available HomeRun and doesn't have an affinity for the same one to come back, so for those with 2 HomeRuns and one goes away, it will try tuners on the second one.

Once the network connection is broken for whatever reason, soon after the HomeRun will terminate that tuner as it sees the client disappear, so the software has no option but start again. It would be possible to append to the same file but this can become problematic as that join is going to be a corrupt splice, so we could see the situation where some decoders might decide to stop playback at that point, or just crash out. Safer to have a second file.

All these things I will take a look at over the Christmas break.

I believe there are going to be some tuning changes coming up later this month (see HERE) I assume we will need to manually retune DvrOnTime, but was wondering @lc200 what effect if any this might have on series links? Thanks.

Series linked entries are kept and automatically updated once the guide has been reloaded after retuning. If you don't retune in time they should all still continue to record even though some channel numbers might have shifted around to allow BBC3 to go back in the list (behind the scenes the Freeview channel numbering isn't used).

I really like the simplicity and reliability of this software, as well as the fact that the recordings can be played on any machine, including my Humax Aura. (Recordings made on the Aura can only be played on that specific machine due to encryption).

For me the downside is still the need to have an always on Windows machine, which in my case is not doing anything else. And I really want to leave the micro$oft straightjacket!

I have recently started using Docker containers for my other home automation bits and pieces (Home Assistant, weather station, etc) and have found that very many programs and services are now available as containers. For example, MythTV is available: see this link Would this be a possible way to make DvrOnTime more widely available and also cross-platform?

I'm a user, not a programmer, so I don't know what would be involved in making this happen? Any comments?
 

Black Hole

May contain traces of nut
I have previously suggested migrating this to Linux where, no doubt, it could run on all manner of low-power hardware such as a Raspberry Pi and a multitude of existing boxes.

The RPi is particularly attractive because of its maker following and therefore large range of parts available. It would be no problem at all to bolt one to the VESA mounting on the back of a telly, and possibly even power it from the TV's USB port (although you might not want to do that for "always on". Then there is the possibility of including tuners on the RPi...

To run on a Pi it would need to be written again using C++ I should think in order to get the performance, possibly implementing APIs special to Broadcom in order to accelerate some packet handling of the transport stream packets, although it might have enough grunt not to need those.

Including additional tuners is also not trivial, I've looked into it and it's a pain in the neck and quite complicated, it would cost money buying all the various tuners and would take considerable time. As Freeview tuners seem to be fast disappearing from the market except for cheap Chinese clones on USB sticks, support from the manufacturers is also now lacking. I did request from Hauppauge three times to get access to their developer code and C# samples to implement their Freeview tuners, and never heard a thing from them.

It was written for Windows and unfortunately I don't have the time or experience to rewrite it for other operating systems. I'm not sure if it would work using Docker, and its not something I have any experience in.

I will say making something cross-platform is making something a jack of all trades and master of none. Take Plex for example, they build the same code base for different platforms, this requires many compatibility libraries to interface the same code to different hardware and hundreds maybe thousands of conditional compile statements to manage, not only does this add all sorts of bugs, it also hits performance. I saw Plex easily eating 20-30% CPU recording just one program using their DVR implementation, compared to DvrOnTime that barely registers, and Plex isn't even reading the packets to extract the EIT info (Plex doesn't do accurate recording). Plex's DVR software was bug ridden and seldom went a few days without a recording failure or some crash, and they have huge teams working on that software, its why I wrote my own! Plex may be better now as I've not used in a couple of years, but that was my experience of 'work on anything' Plex.

What's needed then is somebody with the interest and skills to re-implement your work for the different platform.
Indeed. Also the Freeview packet structure and specification is freely available online, it's heavy going and can be challenging but is complete and doable. I knew nothing about how digital TV worked or how it was transmitted and organised until I started this project and learnt as I went, so perfectly possible for any good developer to follow those specifications and implement the accurate recording functions which is the bit that seems to be missing from other DVR software.

It would be an easier task if your source was available as a starting point rather than totally reinventing the wheel.

Similarly for adding alternative hardware platforms, you can not be expected to bear the expense of buying additional hardware that you have no personal need for but if the source was available on a platform like github others could create forks to add additional function whilst maintaining full credit to you for the initial implementation.
