TvHeadEnd and Oscam = Black Screen

Alexsandro Ednov

Hello,

Im using tvheadend: version 4.3-1789~g6bfeca6c0 with Oscam 1.23 r11429 (compiler: arm-linux-gnueabi)

Im accessing the channels via playlist page, and when im going to watch the channel it gives a empty screen. FTA channels are working great.

Oscam.conf

[dvbapi]
enabled = 1
au = 1
pmt_mode = 4
request_mode = 1
listen_port = 9000
delayer = 60

boxtype = pc

And after making the debug using "tvheadend -d -s -l --debug --trace descrambler,capmt" i can see the CW keys reaching the channel without issue.

Logs oscam:

2019/05/15 20:53:25 573862xx c (ecm) anonymous (1802@000000/0000/0xxx/92:71C22B15xxxxB7DD1DADC61738xxxx): found (578 ms) by Local-testing

So it gives a found ECM key, it sends to tvheadend but still blank screen with no audio

Using ffmpeg to debug the channel (im using pass method)

Program 1
Metadata:
service_name : Channel Name HD
service_provider:
Stream #0:0[0x1f5]: Video: h264 ([27][0][0][0] / 0x001B), none, 90k tbr, 90k tbn, 180k tbc

Stream #0:1[0xf01](por): Unknown: none ([17][0][0][0] / 0x0011)

No audio and no video

FTA channels are working great. But encrypted channels is a big no :(

Is you problem connected with this?

Alexsandro Ednov

No :(

I cant descramble channels using Oscam or CCcam via TVHeadend. The keys are ok, but i cant get video or audio.

More info about how you connect TVH to OSCam?
Config files etc.

Set log format in oscam to

ECM log format: c&0p/i/d/s/l:h.e_w HOP:j

Disable Cycle Check

This is the exact problem I had, and there seems to be nothing wrong with your OSCAM

Are you playing from a .m3u file?

If you do, there are many things you have to think of.

Is your .m3u file in the correct syntax?

What I did was to try only ONE mux.
Copy only stream from your .m3u file (only the stream), and make a new Network -> IPTV Network (NOT the IPTV Automatic Network). Just enter a Network name and nothing more. Hit Create.
Goto Muxes and add a new mux based on you newly created Network. Past your copied stream into URL, and hit create. Do nothing more than that. Hit Create
See if you new mux is scanned with ok, and shows up under Services.
If it shows up under services, click the play-button on your newly created service, and open in VLC. Do not try to play the stream from Muxes, as it will fail. You have to play it from Services. If you get a picture then there is nothing wrong with your OSCAM.
