If you want to remonstrate me personally, please take this off-list, and certainly not Cc the OP who doesn't give a hoot. > I replied to Rob's message before I saw your reply. Fine. My *apologies*. I was quite hasty to reply about a pet peeve. > Given that those two were the only two that actually worked of all the options > I tried, Then conversly, kindly provide your attempts. The D-Link does RTP and RTSP. http://us.dlink.com/products/connect/hd-wi-fi-camera-dcs936l/ http://support.dlink.ca/emulators/dcs930L/100/helpadva.htm HTTP for config. > IIRC, you will have to be a bit more explicit and specific in your criticism > if you want to be taken seriously rather than off-handedly trashing them as > you have done for many other technologies in the past without elaborating, I did, but I am not going to explain every single background concept, and I've already often annoyed other users with TMI. Two, that's not fair, especially for software certain people use and thus like to be defensive and tune out about because they've developed emotional attachments over their long stable lifetimes and have never known better. We are not getting into that debate here, and I recall very specific technical points just being outright ignored. Tools that don't do the job belong in the bitbucket. Developers may deserve respect, but not tools. > assuming that everybody else knows what you are talking about. I already provided a link. I'm not going to repeat a decent third party explanation. If you're not interested, don't read, and *THAT'S FINE*. But I am probably not the only one who is tired of dealing with under-maintained, bug-laden, most likely insecure software... that *still* gets recommended. It only takes one suggestion to drag down a lot of unsuspecting users, most of which who want it to just work and not deal with this mess. > Please educate us rather than effectively making us all feel stupid because we > don't follow your unstated line of reasoning. I did state. Follow the references if you like. No personal attack there, but I was specific about the whole ffmpeg vs libav shebang because some people on this list had the misfortune of being dragged down by those distro politics. They know who they are, and they know how to deal with it, and I am acknowledging them. The rest? They can tune out. ___ Linux mailing list Linux@lists.oclug.on.ca http://oclug.on.ca/mailman/listinfo/linux

Use MPV. https://github.com/mpv-player/mpv/wiki/FAQ#How_is_mpv_related_to_MPlayer Old news. Just: mpv the://stream/URL As for VLC, the UI is annoying to describe over email, and the CLI worse even than MPlayer(2?)/MPV. At that point, just ffmpeg -re -i whateverYourStreamIs -whywouldyouneedanymoreflags -f sdl 'DCS-936L' KISS. Now, if you insist on sticking an old version of Ubuntu or Debian, or any other distro, that dragged its users down with the libav vs ffmpeg tiff, tough. ___ Linux mailing list Linux@lists.oclug.on.ca http://oclug.on.ca/mailman/listinfo/linux

Given that those two were the only two that actually worked of all the options I tried, IIRC, you will have to be a bit more explicit and specific in your criticism if you want to be taken seriously rather than off-handedly trashing them as you have done for many other technologies in the past without elaborating, assuming that everybody else knows what you are talking about.

I'm quite familiar with the Ottawa-based Lumenera cameras, having written Linux firmware kernel imager drivers for them: https://www.lumenera.com/products/surveillance/le375.html They are just a web page on the device configured by default with DHCP. Image streaming is MJPEG wrapped in HTML. Image streaming can be configured for RTSP/RTP. They don't do IPv6. I recently bought a Hikvision camera that needed another driver supplied for Windows. I was able to configure it via HTTP, except for live exposure view and setting up motion alarms and privacy masks which needed the plugin. I was able to use RTSP to stream the live output of that camera using standard open source tools (such as VLC? or maybe mplayer?) but wasn't able to get RTSP working within a web browser for configuration. This camera does IPv6. > rday slainte mhath, RGB -- Richard Guy Briggs -- ~\-- ~\ -- \___ o \@ @Ride yer bike!

What's the protocol that it uses to send video? Does it require any form of authentication? I'd nmap it, sniff it, or find a manual. I know the ffmpeg command line utility can trivially set up a receiver for quite a few protocols, be it RTP (feed it SDP on stdin), or other. See ffmpeg-protocols(1).
