Trying to get HDHomeRun working - streams profile issue

Ron Von · 2017-10-29T02:24:12+00:00

I think I pretty much got it all done, but I just can't get video to play. I am suspicious I need to build a stream profile, or tweak an existing one? Anyon...

Using HDHomerun Connect device. Everything runs super good. Gave up launching stream on browser, as there can be a lot of settings set wrong (wrong format, port, browser settings). Playing it on OpenElec via Kodi. using TVheadend plugin.

Just for reference, Here's my log when tuning to a channel, watching a couple of seconds, then stopping using the internal viewer.

This is with an HDHomeRun Extend US version which is set to mobile transcode profile, so the video comes in as h.264.

It looks like Tvheadend is tuning a reasonable frequency for your channel 39, but then doesn't get the data stream expected. Which pre-defined muxes did you choose when setting up your network? Can you set your Extend for mobile transcode profile just to see if it makes a difference?

I tried creating my own muxs and using the predefined ones. Both scan up successfully. I also tried changing the HDHomeRun transcoding profile to the various profiles and rescanned the muxs each and every time. Every time the log shows "mpegts", and every time I use the built in "Watch TV" viewer I get the same result "Unknown error occurred", and I often see this in the logs:

017-11-09 19:00:00.271 TS: HDHomeRun_2/623.028MHz/{PMT:48} Transport error indicator (total 1)

2017-11-09 19:00:00.271 TS: HDHomeRun_2/623.028MHz/{PMT:48}: MPEG2VIDEO @ #49: Invalid start code 15:d5:c9

I give up on TVHeadend (for now). This reminds me of trying to add a new device (say modem) into an old Windows operating system like 3.11 or NT and having to scour usenet groups trying to find the answer. There had got to be a bug in the TVHeadend code that somehow I am triggering. I got HDHomeRun working on Emby media server in 2 minutes so I'm good to go. If someone has a "ah haaa" moment feel free to post and I will check in from time to time.

Thanks for all your help everyone, especially you Jerry, you really tried. Hope to chat with you again someday. Maybe when/if I try some sort of SAT>IP system if I can find one for Canada.

The only time I've seen "Invalid start code" is from corruption usually due to an encrypted steam.

Could you provide a mux (or a stream) sample?

For a mux go to the muxes tab, copy a play link and do something like.

wget -O tvh.ts http://ip:port/play/stream/765324yuig6879gytyuf76d56

Do that for about 30 seconds and attach it to a new issue on here (link to this thread).
