Transcoding LiveTV

[sub]

in the url you posted, you had two question marks, which is incorrect. The second on, at the end of the channel number is probably stuffing up the channel number parameter.

it should be

Code:

/transcode?channel=505&resolution=720x406&bitrate=900k

not

Code:

/transcode?channel=505?resolution=720x406&bitrate=900k

Arrgh, fat-finger by me. Tried again (fix second ? to &). I do see traffic in the log now, but client doesn't seem happy with it (tried Chrome, WMP and VLC - all 3).

Thoughts? I could try a recording also ... do I just change channel=505 to (for example) recording=902 (one of my recordings)?

Thanks!

Sorry, crossing posts. In your example above - is the space needed (e.g. 9 00k)?

Thanks!

No, that's just the forum formatting. I've fixed it above.

NP, and I did see the fat finger - sorry! Fixed it, but still no joy. I do see outgoing traffic noted in the log, but not being played by the clients. Hmmm ... not sure what I'm doing wrong. Will keep working at it!

Thanks!

Yep, as mentioned early in this thread - this is problematic and not supported. In some scenarios it works great. Others no so great.

NP, completely understood. Let me dig a bit - could be the command line, or version of ffmpeg. Will let you know if I have any luck.

Very much appreciate the help, and quick response. And I like the donate button on the new version - will go in tonight and do so, hope others do also!

Thanks again.

Hi,

If I'm reading the logs right (which I may not be!), ffmpeg is transcoding to a file, and then NextPVR is streaming that back to the client - is that correct? If it is, and this may be a dumb question but ... why not also have ffmpeg stream this directly back to the client (as this is an argument that can be used)? Is it possible to have this available (optional parameter in the URL?)? Asking as that may let me try to debug this a bit more (right now I can't really do much about the outgoing stream).

Or do I have this messed up?

Thanks!

Hi,

BTW, if I move to a newer version of ffmpeg (that I built today), and use the command line / parameters above in this thread, streaming seems to happen, but then I get these errors,

2015-08-29 23:44:40.467 [ERROR][24] Unexpected error streaming channel: System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host
at System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
at NShared.Streaming.StreamingHelper.StreamNative(Socket conn, Dictionary`2 parameters)

And a bit later,

2015-08-29 23:45:33.038 [DEBUG][21] native stream exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at NShared.Streaming.StreamingHelper.StreamNative(Socket conn, Dictionary`2 parameters)

Actually, going back to the original config.xml (and older ffmpeg) - after a recording service restart I'm able to generate a similar result (first error above, not the second).

Thanks!

It can't send directly back to the client. The user requested the stream via an http request, and the way http works it requires you to respond to the request on that same socket (which is inside NRecord.exe). You can't pass that socket to another process (ffmpeg.exe).
