  • Capturing and processing a live RTMP stream

    8 février 2018, par Yantor

    I’m trying to download a live stream (not a file) coming from a live camera feed available at the following website : http://www.dot.ca.gov/video/.

    I used Wireshark for sniffing the TCP packets and was able to extract the RTMP parameters, but wasn’t able to use them with FFMPEG/VLC for downloading / playing the stream on VLC (I guess I didn’t construct the URL correctly).

    for example, for the camera feed available here, I got the following parameters :

    swfUrl : http://www.dot.ca.gov/research/its/StrobeMediaPlayback.swf

    pageUrl : http://www.dot.ca.gov/d4/d4cameras/ct-cam-pop- N17_at_Saratoga_Rd.html

    tcUrl : rtmp ://wzmedia.dot.ca.gov:1935/D4
    Play : E37_at_Lakeville_Rd.stream.

    Is there a chance someone is familiar with this and can help with understanding how I can use the above for downloading the stream ?

    Thanks a lot ! Yaniv

  • How do I live transcode a wmv file for playback in html5 player ?

    14 octobre 2018, par steven

    I’ve been working at this for quite awhile and still haven’t found a solution that works. I need a way to live convert (transcode) a .wmv file for playback in a html5 web player.

    I have a linux server (Apache) setup to stream video files through an html5 web player (Video.js) designed for Chrome and Firefox browsers. The file types I am dealing with are .mp4 (H.264), .mkv, and .wmv. The good news for me is that I can deal with mp4 and mkv natively, however I can’t play wmv. Also, I have to deal with a lot of files, change periodically, and can be quite large.

    After doing a lot of research and reading many times how you can’t stream wmv directly, I came to the realization that I had two options. Either convert the file to a supported format or live transcode a file for use in the web player. Due to the amount of files and their size (and periodically changing) converting the file is simply not feasible. So I am stuck with live streaming/transcoding. I figured ffmpeg would be the way to go, but I have yet to figure out how to get ffmpeg to live stream into the html5 player.

    So how do I take an existing .wmv file and live stream it in an html5 player ?

    The things I’ve tried so far :

    Tried creating a m3u8 playlist and hoping it would magically work.

    ffmpeg -i "hello.wmv" -s 640x480 -c:v libx264 -f ssegment -hls_flags delete_segments -segment_list playlist.m3u8 -segment_list_type hls -segment_list_size 10 -segment_list_flags +live -segment_time 10 out_%6d.ts

    Simply copying to mp4 and streaming while ffmpeg still progressing. Obviously didn’t work.

    ffmpeg -i "hello.wmv"  -vcodec copy video.mp4

    Converting to webm format and streaming webm while ffmpeg still progressing. This actually did show the video for a few seconds in the html player :

    ffmpeg -i "hello.wmv" -codec:a libvorbis -codec:v libvpx -b:a 128k -b:v 1200k video.webm

    Ffmpeg is not required to be used (was thinking of vlc as well), the html5 player is required. Completely converting then streaming isn’t a viable option because file sizes can be too large and change periodically. What command/program can I use to stream the file for playback in the html player ?

  • How to live stream video securely ?

    16 février 2018, par casper04

    I have an IP Camera which sends out a RTSP stream over UDP. On the same network I have an Intel Edison where I can send the stream to, to possibly convert the stream and make sure it’s sent securely. From the Edison I want to send the stream to a server, where the stream is stored and sent out to the client (a browser).

    Now I know that the best option to stream video on different browsers is HTTP Live Streaming, which means I should convert the stream to a format which is compatible with HLS. And as I understand it, this can be done with FFMPEG (which, I believe, also works on Yocto Linux, which is what is running on the Edison).

    What I don’t want however, is that the stream that I’m sending out can be easily watched by people who are not authorized. Therefore, I would like to either encrypt the stream (and decrypt it on the server), or send it over HTTPS. Is this possible, and if so, how ?
