Help with pipe HTTP video

Added by Cleiton Oppenheimer over 3 years ago

Hi, I have been trying to follow some instructions found here on the forum, to successfully add my USB Webcam to a IPTV Mux.

Basically I'm running motion to stream it over HTTP. I am able to stream the WebCam using VLC using: http://192.168.0.122:8081.

I have tried do pipe this into a MUX, but unfortunatelly it is not working. I'm using:

pipe:///usr/bin/ffmpeg -i http://192.168.0.122:8081 -vcodec copy -acodec copy -f mjpeg pipe:1

as the URL for the MUX.

Checking the Log on TVH, shows me:

I have already tried using "-f mpegts" as an argument, but nothing changes.

Also have tried to follow the "Consider increasing the value for the 'analyzeduration' and 'probesize' options", but no changes.

Can someone help me on how to proceed?

BTW, I am using a SBC with relativelly low processing (ARM QuadCore).

RE: Help with pipe HTTP video - Added by saen acro over 3 years ago

Transcode stream to some iptv supported format, vp8/h264 for example.

RE: Help with pipe HTTP video - Added by Cleiton Oppenheimer over 3 years ago

Unfortunately, it seems to be too much for my Nano Pi Zero Pi to perform transcoding. CPU usage goes to 300% using h264.

Specs:
Number of Cores: Quad-core
Frequency: 4 x Cortex-A7 Up to 1.2GHz
Memory RAM: 512MB

I will probably try to get a new Cam with h264 output support or move to a raspberry pi to take benefit of hw-transcoding.

If any other suggestion is still available to keep the system with the current devices, please let me know.

RE: Help with pipe HTTP video - Added by saen acro over 3 years ago

Use hardware transcoder OMX or MMAL

RE: Help with pipe HTTP video - Added by Cleiton Oppenheimer over 3 years ago

Are OMX or MMAL supported by any kind of hardware? I could find few posts referencing only the Raspberry Pi.

If these could work with my FriendlyArm, that could be of great help.

RE: Help with pipe HTTP video - Added by Cleiton Oppenheimer over 3 years ago

Using OMX I am able to transcode live WebCam to a file using:

ffmpeg -f v4l2 -i /dev/video0 -codec:v h264_omx -b:v 2048k webcam.mkv

How can I edit this command to be used as pipe? Changing webcam.mkv to pipe:1 gives me the following error:

service instance is bad, reason: No input detected

RE: Help with pipe HTTP video - Added by saen acro over 3 years ago

Output as MPEGTS.

RE: Help with pipe HTTP video - Added by Cleiton Oppenheimer over 3 years ago

Using "-f v4l2" produces the following output on the log:

It seems like something is happening now, but no stream is presented opening the MUX on VLC. After few seconds TVH also stops what seems to be some transconding.

RE: Help with pipe HTTP video - Added by Cleiton Oppenheimer over 3 years ago

I am very happy to share that I could reach my goal using the following command line:

pipe:///usr/bin/ffmpeg -f v4l2 -i /dev/video0 -codec h264_omx -b:v 2048k -f mpegts -tune zerolatency pipe:1

This could reproduce my chinese webcam in TVH.

Now I have 01 channels mapped streaming my webcam and 02 from old phones generating rtsp.

There is only one thing that I would like to achieve so that this setup goes to 100%. I would like to keep these muxes "always tuned" so that when selecting a channel would not need the tuning timing (few seconds) to be displayed. I compare this when opening 2 streams of the same file. The second one will load almost instantaneously.

The stream from the WebCam, will not allow me to stream 2x the same channel, while the rtsp streams from my mobiles allow it (all the 03 muxes are set for the same IPTV Network). Any hints on how to change it? TVH shows input/output bps for the second stream, but on the screen everything remains black.

RE: Help with pipe HTTP video - Added by Cleiton Oppenheimer over 3 years ago

Hi

I could successfully use diferent sources of live video with TVHEADEND.

Basically my setup is based in a raspberry pi 3 with hardware transconding.

I have the following as inputs:
- RTL-SDR Software Defined Radio - with rtl_fm_streamer (https://github.com/AlbrechtL/rtl_fm_streamer)
- Chinese low cost 1080p WebCam
- Several old smartphone devices running Live-Reporter app (https://apps.apple.com/br/app/live-reporter-live-camera/id996017825) (https://play.google.com/store/apps/details?id=net.kzkysdjpn.live_reporter&hl=en_AU&gl=US)
- ISDB-T with all FTA Terrestrial Channels broadcasted in my city
- Some Twitch.tv channels of my interest (here, you can try youtube or other sources of live video)

I'm pleased to share the command lines used to pipe these inputs to my MUXes.
- Stream form my old phones with Live Reporter App:
pipe:///usr/bin/ffmpeg -i rtsp://192.168.0.58:554 -vcodec copy -acodec copy -f mpegts pipe:1

- Stream from chinese WebCam, with HW transcoding:
pipe:///usr/bin/ffmpeg -f v4l2 -i /dev/video0 -codec h264_omx -b:v 2048k -f mpegts -tune zerolatency pipe:1

Live FM Stream with some stations broadcasted in my town:
pipe:///usr/bin/ffmpeg -i http://127.0.0.1:2346/95300000 -c:a ac3 -f mpegts -mpegts_service_type digital_radio pipe:1
(in this case, you must enter the desired frequency to be input to rtl_fm_streamer)

Live Twitch.TV channels of my choice:
pipe:///usr/bin/env streamlink --stdout --twitch-disable-ads https://www.twitch.tv/YOURTWITCHCHANNEL best
(in this case, I used streamlink, available from https://github.com/streamlink/streamlink)
To compile it in RPi:

sudo apt install git python3-setuptools
git clone https://github.com/streamlink/streamlink
cd streamlink/
sudo python3 setup.py install

ISDB-T channels mapped in the standard way with TVHeadend.

This is my setup and settings and I'm really help with it. Sharing in case of it being helpful for somebody else.

Improvements needed:
Since I have plenty of bandwidth (gigabit Network) and most of the streams are generated by myself, It would be great to have the IPTV Networks like "always broadcasting" so that all the MUXes are tuned everytime. This will cause the streams to be opened almost instantaneously not loosing time with spawns or ffmpeg/pipes. I don't care using processing aswell since this Pi is dedicated to it. If anyone have a hint on what to search for...

Tks
