Serving rtmp on port 1935
22 mai 2020, par JJ The SecondI've been trying to get ffmpeg to stream in rtmp but connection to port 1935 is always refused. I really don't know what else I can do to allow this connection.



Here is what specs I'm running.



- 

- Ubuntu 18.04 (tried with 19.04) however same issue - here is why I think I've made a mistake
- No Nginx installation at the moment
- FFMPEG "ffmpeg version 3.4.6-0ubuntu0.18.04.1 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.3.0-16ubuntu3)"









This is the script I run :



ffmpeg -i "test.mp4" -c:v copy -c:a copy -f flv "rtmp://127.0.0.1/stream/test"



Error I get is :



[tcp @ 0x55ff05ab8ce0] Connection to tcp://127.0.0.1:1935 failed: Connection refused



I've done some research and been across many posts about ffserver.conf and I have made those changes but still no luck. Here is my config file. I also have ran ffserver once using this config.

Here is my ufw status :

1935/tcp ALLOW Anywhere
22/tcp (v6) ALLOW Anywhere (v6)
22 (v6) ALLOW Anywhere (v6)
1935/tcp (v6) ALLOW Anywhere (v6)



but still nothing, I've also opened ports in iptables but no luck. Here is how this is done :



iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 1935 -j ACCEPT

and

iptables -A OUTPUT -m state --state NEW -m tcp -p tcp --dport 1935 -j ACCEPT



and still nothing, every time I run ffmpeg I get connection refused. I have previously installed nginx just to test but no luck.



What am I doing wrong here ? Isn't this port suppose to be open now ?



Thanks

OpenCV VideoCapture can't read from stream
18 décembre 2018, par Josep VallsI can open a stream in VLC but in OpenCV I cannot capture frames. (Python 2.7, OpenCV 3.4.3 binary distribution x86, Windows 10). I’ve been following this guide : https://medium.com/@tomgrek/hackers-guide-to-the-aws-deeplens-1b8281bc6e24 but I cannot seem to read from random streams online (not sure whether I should be able to, I saw this question opencv videocapture can’t open MJPEG stream about compiling with ffmpeg but I just downloaded the binary available in Sourceforge).
-
I am using an AWS Deeplens, updated to the latest version.
-
Installed ffmpeg, latest version.
Then, in /etc/ffserver.conf I added :
<stream>
File "/opt/awscam/out/ch1_out.h264"
VideoFrameRate 6
VideoSize 320x240
NoAudio
</stream>
<stream>
File "/opt/awscam/out/ch2_out.mjpeg"
VideoFrameRate 3
VideoSize 640x480
Format mjpeg
NoAudio
</stream>- I start
ffserver -f /etc/ffserver.conf - On my Windows machine, I use WSL and open an SSH tunnel into the AWS Deeplens
ssh -L 8090:localhost:8090 aws_cam@192.168.0.10 - At this point, in my Windows machine I can open VLC and if I point to
http://localhost:8090/camera.mjpegI can see the stream from the camera.
But if I run the following code :
cam = cv2.VideoCapture("http://localhost:8090/camera.mjpeg")
success, frame = cam.read()
opened = cam.isOpened()
success, frame, openedI get :
False, None, FalseIf I browse to
http://localhost:8090/stat.html, I see :Available Streams

VideoCapture()I see how the number ofServedfor thecamera.mjpegstream increased by a 2 or 3 and thebytes, increases a few megabytes but I don’t see anything in OpenCV. I have not tried any other video device in my Windows 10 but I can read images no problem. I also tried a random stream online, also opens in VLC but not in OpenCV, tried this one : http://136.176.70.200/mjpg/video.mjpgAny ideas ?

Playing fragmented mp4 doesnt continue playing
18 mai 2017, par advinerUsing ffmpeg I create an mp4 using my video camera as the source.
ffmpeg -f dshow -i video="Integrated Webcam":audio="Microphone (Realtek High Definition Audio)"^
-g 52^
-vcodec libx264 -pix_fmt yuv420p -profile:v baseline -level 3^
-f mp4 -movflags empty_moov+default_base_moof+frag_keyframe^
%OUTPUT%\video.mp4Works with IE11, Chrome and Firefox
And my html video tags :
<video controls="controls" autoplay="autoplay" style="width:640px;height:360px;">
<source src="http://localhost/video.mp4" type="video/mp4;codecs="avc1.42E01E, mp4a.40.2""></source>
</video>The node web server version just has src="http://localhost/" for the
using
I’ve tried nginx and a node version that I got from this site
The nginx doesnt do anything special. I just basically point the root to the folder so it sees the mp4.The problem is it only plays however much the webserver sees when the page is loaded. The file is still continuously growing. And if I refresh the page I can see the time length is now longer since the last time.
My question is how can I make the video tag continuously play the fragmented video data without stopping and refreshing the page (which starts from the beginning again) ?
