Tvheadend

I do not know how to use the json api for adding something. I just use it to get some status information.

With a python script derived from
https://github.com/tvheadend/tvheadend/blob/master/support/htspmon
I am using the Home Tv Streaming Protocol (HTSP)
https://tvheadend.org/projects/tvheadend/wiki/Htsp
with a modified version of
https://github.com/adamsutton/tvheadend/blob/master/lib/py/tvh/htsp.py
to add, cancel and delete DVR entries in Tvheadend 3.9.2293

This works very well for me.

I would think that those scripts should also work with Tvheadend 4.0, and can post them if you are interested.

Thanks for your reply.
Python HTSP-library could do the job for me, but i cant make it work.

When i initialize and send hello:
htsp = HTSPClient((opts.host, opts.port))
msg = htsp.hello()

the script crash and i get the following stacktrace.

Traceback (most recent call last):
File "htsp.py", line 110, in <module>
r=h.hello()
File "htsp.py", line 79, in hello
resp = self.recv()
File "htsp.py", line 66, in recv
ret = htsmsg.deserialize(self._sock, False)
File "/sda1/home/dag17/pyapp/tvserver/htsmsg.py", line 207, in deserialize
ret = ret.next()
File "/sda1/home/dag17/pyapp/tvserver/htsmsg.py", line 195, in next
raise StopIteration()
StopIteration

Is there maybe a difference in HTSP between 3.x and 4.x?
More ideas?

I am not sure about the differences between 3.x and 4.x

Maybe you need to change the protocol version in line 32 of htsp.py to the protocol version of your Tvheadend server.

I set the protocol version to 17 which is used by Tvheadend 3.9.2293.

I had another look at you traceback and was wondering about this

File "htsp.py", line 110, in <module>
r=h.hello()


There seems to be an itermediate step for calling hello.

I have found the problem with my Python-htsp, i used wrong port-number.
HTSP uses 9982, i tried with 9981.

Now i think i can get my frontend working again, with HTSP in stead of HTTP api.

Thanks for all help.
