NextPVR web player stuck at Receiving Data, Black Screen. Need Help

[sub]

I am not even sure if TV's that can scan and play clear QAM can decode h264.

Yep, good point - that is unlikely to be the case.

[briantho]

Hmm, ok so what are you suggesting? I have several older (like 3-6 years old) HDTV's that I'm using. Like I mentioned I am not using a Set Top Box, except for one. The other TV's are able to receive a good number of analog channels. Again they are all connected to the same coax source from the cable provider. I don't think these TV's ever worked with the digital h.264 channels. They do however work with the analog channels. The thing is I'm wondering if I can get my TV Tuner to tune to the h.264 channels, or as a last resort have the analog TV working. I am almost positive the cable company is broadcasting some channels in analog, and some channels in digital. Is there a better way to tell if a channel is encrypted? If you want I can try uploading a stream sample of the h.264 channels later today. 

Also here is the command when running "ffmpeg -list_devices true -f dshow -i dummy"

He's just saying they're likely analog channels that are being tuned by your TV (rather than the h.264 digital channel)

NextPVR v5 no longer natively supports analog. You might be able to make analog work using an Extras plugin, but there is a fair bit of manual effort required for that.

Ok, so should I just use v4 along with the analogdevices.xml file, or is this something that can be added into v5 later on? also, here is the h.264 sample

Let me know what you find out. Thanks again

[mvallevand]

Regarding the analog support if you continue follow through from the other thread try;

ffplay -f dshow -i video="Conexant USB Polaris Analog Capture"

Does it play anything?

Yep - encrypted audio and video streams.

Well Shoot. That's what i figured, thanks for confirming. Anyway, regarding analog and v5, is it a "later feature" or a "no longer supported"?

also, Martin
when I run the command you gave me it says at the end

Failed to set value '-f' for option 're': Option not found

What does that mean?

[mvallevand]

It means that you didn't notice that I took out the -re after I posted my message.

Analog support was kind of half done in v5, when using a Windows install. I will likely find some time in the future to get it working.

Analog support is a pretty low priority these days, with just about everybody using digital tuners now.

Ah ok, That was the problem. However, when I run
ffplay -f dshow -i video="Conexant USB Polaris Analog Capture"

I get an error

[dshow @ 038d1980] Could not find video device with name [Conexant USB Polaris Analog Capture] among source devices of type video.

video=Conexant USB Polaris Analog Capture: I/O error

I assume it's supposed to be "Conexant Polaris Video Capture"
in which case no error, but no output either

In any case, I'm potentially thinking I'm going to downgrade to v4, until analog support is added on v5, unless I can somehow get ffplay to work correctly. Also, what is supposed to happen with ffplay? I get no output, when running
ffplay -f dshow -i video="Conexant Polaris Video Capture"
Let me know what is supposed to be the output, otherwise I will probably go back to v4. Anyway, thanks for helping me. I really appreciate it.
