Can not play IPTV channels from services Tab (also not as Channel)
Added by Paul Brunniem almost 8 years ago
Hi,
I have the following setup:
- Iqon force 2 reciever (enigma2/openatv) as IPTV source
- reciver has CI module to encrypt channels (works)
- IPTV automatic Network with .m3u from the reciever
- scanning the m3u and the muxes works
- playing FTA and Encrypted channels over the muxes tab works
- playing FTA from services tab works
- playing encrypted channels from services tab does not work
In VLC the stream does not work.
The encryption should already be done from the receiver.
Any suggestions?
edit: some more info:
The tv receiver delivers mpeg-ts streams. Here are examples from tvheadend.
Channel Junior:
Is encrypted, can be watched in the receiver and in tvheadend over the muxes tab.
VLC shows following codec info on playback:
Stream 0 Type: Video Original ID: 1791 Codec: H264 - MPEG-4 AVC (part 10) (h264) Resolution: 720x578 Display resolution: 720x576 Frame rate: 25 Decoded format: Planar 4:2:0 YUV Stream 1 Type: Audio Original ID: 1792 Codec: MPEG Audio layer 1/2 (mpga) Language: German Channels: Stereo Sample rate: 48000 Hz Bitrate: 192 kb/s Program 19 Scrambled: Yes
On the Services tab tvheadend has created the right service entry (I think) with following info:
Index PID Type Language Details 0x06ff / 1791 PCR 0x0066 / 102 PMT 4 0x06ff / 1791 H264 5 0x0700 / 1792 MPEG2AUDIO ger 1 0x1b70 / 7024 CA CAIDS: 09c4:000000 2 0x1a70 / 6768 CA CAIDS: 098c:000000 3 0x1f70 / 8048 CA CAIDS: 09af:000000 After filtering and reordering (without PCR and PMT) Index PID Type Language Details 4 0x06ff / 1791 H264 5 0x0700 / 1792 MPEG2AUDIO ger 1 0x1b70 / 7024 CA CAIDS: 09c4:000000 2 0x1a70 / 6768 CA CAIDS: 098c:000000 3 0x1f70 / 8048 CA CAIDS: 09af:000000
When I play the service VLC can not play it (no error or something, just no output) and shows following codec info:
Stream 0 Type: Video Original ID: 1791 Codec: H264 - MPEG-4 AVC (part 10) (h264) Stream 1 Type: Audio Original ID: 1792 Codec: MPEG Audio layer 1/2 (mpga) Language: German Description: clean effects
There are no errors in tvheadend webinterface log all the time.
edit2:
I'm running HTS Tvheadend 4.1-2405~geb495a0~xenial at the moment.

Does no one have an idea?
This issue is the last that prevents me from running my TV system (at the moment).

OK guys (I'm answering myself again), I found a solution for my use case but its a bit slow.
Background:
Like I said in my fist post, the mpeg-ts source from the receiver is decrypted already. What we also see in the first post is that the source contains the CA streams (encryption something) besides the video and audio streams. So I think Tvheadend recognizes the services generated from the mux as Encrypted. It shows the services in services-tab as encrypted by checking the appropriate column. I guess Tvheadend tries to decrypt the streams when I want to play the service, but cant.
So I thought about how could I get Tvheadend to not think the channels are encrypted.
Solution:
I'm now using a pipe string to push the input mpeg-ts trough ffmpeg, mapping all streams, discarding unknown streams (like CA) and returning mpeg-ts again.
The pipe looks like this:
pipe:///usr/bin/ffmpeg -loglevel fatal -i http://INPUT -map 0 -c copy -ignore_unknown -metadata service_provider=PROVIDER -metadata service_name=CHANNEL -f mpegts -tune zerolatency pipe:1
After that Tvheadend generates the services without encrypted flag and I'm able to play the services, map them to Channels, watch in Kodi and do records over tvheadend. -> Nice
But:
It is little slower then without pipe and has a little odd behavior:
I cant, or cant most the time, play the muxes from the muxes tab with VLC. The log looks like this:
2017-01-19 21:51:21.099 mpegts: services_pipe.m3u - Disney Cinemagic HD in IPTVPIPE - tuning on IPTV 2017-01-19 21:51:21.106 subscription: 00E6: "HTTP" subscribing to mux "services_pipe.m3u - Disney Cinemagic HD", weight: 10, adapter: "IPTV", network: "IPTVPIPE", service: "Raw PID Subscription", hostname="****", client="VLC/2.2.4 LibVLC/2.2.4" 2017-01-19 21:51:21.108 spawn: Executing "/usr/bin/ffmpeg" 2017-01-19 21:51:26.842 webui: Stop streaming /stream/mux/396cb73f01bf2661a6e9e00ed3a1fbd3?ticket=E1BF047F223D70DED00354FAC6F5C63B774B4373, timeout waiting for packets 2017-01-19 21:51:26.842 subscription: 00E6: "HTTP" unsubscribing, hostname="****", client="VLC/2.2.4 LibVLC/2.2.4"
Ok that "Problem" is no gamebreaker for me. So is also not the next one.
When I play the service or the mapped channel with VLC, VLC shows fragments in the video and it does stutter. I would blame VLC for this. Maybe something with caching what can do Kodi better or something.
The tuning of the piped channels is slower then direct play. This gets relevant when zapping with Kodi. Zapping from one channel to another does now take about 10 Seconds. Unencrypted channels without pipe take 5 seconds.
So you see, its littleof slower then direct but OK for me at the moment.
Final questions are:
1. Is it a bug that Tvheadend recognizes not encrypted streams/services as encrypted when there are encryption info (CA) in the container?
2. Is there a chance to tell Tvheadend that a service is not encrypted? (Maybe make the flag editable or add a flag to the network to tell that there are no encrypted muxes in the network)
3. when I use pipes, what is the right syntax to write spaces in the metadata without getting errors when tuning (like -metadata service_name=Disney Junior HD)?

Any update on this?
I have the same problem.
Tvheadend should ignore the CA since the stream is already being decrypted in the source.
Thanks
