mjpg_streamer would like to capture stills on SD card



  • I have a streaming webcam using an old logitec webcam and mjpg_streamer -i "input_uvc.so -d /dev/video0 -y" -o "output_http.so -p 8080 -w /www/webcam/". Works fine. I'd like to capture stills to my SD card. Researching the mjpg_streamer parameters, it appeared that mjpg_streamer -i "input_uvc.so -d /dev/video0 -y" -o "output_file.so -f /tmp/mounts/SD-P1/pics -d 5000" would capture a file for me every 5 seconds. However, the opkg build installation did not include (or else I can not file) output_file.so. Anyone know how to build this plug in for mjpg_streamer on the onion?



  • @Brad-Hontz I compiled mjpg_streamer with most of the stuff enabled, grab it at https://dl.dropboxusercontent.com/u/11811685/omega2-stuff/mjpg-streamer_r182-8_mipsel_24kc.ipk and try, if it works for you.

    Thanks for the quick reply. I rsync the ipkg to my onion and attempted opkg install:
    root@Omega-0000:/www/webcam# opkg install mjpg-streamer_r182-8_mipsel_24kc.ipk
    Installing mjpg-streamer (r182-8) to root...
    Collected errors:

    • opkg_install_pkg: Package mjpg-streamer sha256sum mismatch. Either the opkg or the package index are corrupt. Try 'opkg update'.
    • opkg_install_cmd: Cannot install package mjpg-streamer.

    I tried opkg update and then repeated but received the same. Could likely be doing something wrong here (grommet level) so happy to take on the help. Thanks in advance.



  • I was wanting to do the same thing, but then FTP the file to my webserver online for a weathercam link.

    Getting the same error as well.



  • May also want to try the LEDE version of the mjpg streamer doing a forced install over the onion version.



  • @Brad-Hontz @Brad-Buskey @WereCatf

    Has anyone found the output_file.so?

    I wish to capture a images based on a hardware trigger and ftp/email/scp/curl/wsend to a remote server.

    I notice that the streamer, once launched, does not return you to the ssh prompt. Does that mean that, if you called it in a script (or python or ruby or..) it would simply get stuck there? I know I can connect using a second ssh connection and from there do a wget http://xxx.xxx.xxx.xxx:8080/?action=snapshot -o logFile and then examine the log file to find the image name (typically seems to be called index.html?action=snapshot), rename it to a more useful name (e.g. myImage.jpg) and email that. I suppose a second script could be written, and launched via a second ssh session, to do the action=snapshot based on the hardware trigger but this seems rather clunky.

    Have you guys come up with something yet?



  • @Jo-Kritzinger The package I gave above includes output_file.so:

    opkg remove mjpg-streamer
    cd /tmp
    wget https://dl.dropboxusercontent.com/u/11811685/omega2-stuff/mjpg-streamer_r182-8_mipsel_24kc.ipk
    opkg install mjpg-streamer_r182-8_mipsel_24kc.ipk --force-checksum
    

    Just ignore the complaint about checksum-error, it won't match any of the packages you have in the repos, since it comes from my own repo.

    Also, you can fork mjpeg_streamer into background by adding -b to the list of parameters you give to it. Just for future reference, it's sometimes helpful to check what parameters an app supports by calling it with --help...



  • @WereCatf Thanks for the response, however, I get an error:

    opkg install mjpg-streamer_r182-8_mipsel_24kc.ipk --force-checksum
    Installing mjpg-streamer (r182-8) to root...
    Ignored mjpg-streamer sha256sum mismatch.
    Collected errors:

    • satisfy_dependencies_for: Cannot satisfy the following dependencies for mjpg-streamer:
    • libv4l *
    • opkg_install_cmd: Cannot install package jpg-streamer.


  • @Jo-Kritzinger libv4l is available from the LEDE-repos.



  • @WereCatf thanks. Did not see it in opkg. New to this world. I believe it is retrievable using rsync? Would appreciate a pointer in the right direction.



  • @Jo-Kritzinger Add src/gz reboot_packages http://downloads.lede-project.org/snapshots/packages/mips_24kc/packages to /etc/opkg/distfeeds.conf and do opkg update



  • @WereCatf awesome, thanks. Will try.



  • @WereCatf Tried and I get 100's of lines similar to this:

    Package zope-interface version 4.3.2-1 has no valid architecture, ignoring.
    Package zsh version 5.2-1 has no valid architecture, ignoring.

    Then it ends with:
    Trace/breakpoint trap



  • @Jo-Kritzinger You must have done something wrong, it definitely shouldn't spit out such things. Are you sure you didn't typo anything?



  • @WereCatf
    Modified distfieeds:
    root@Omega-xxxx:~# cat /etc/opkg/distfeeds.conf

    Then I rand the update:::

    This is how I installed:
    opkg install mjpg-streamer_r182-8_mipsel_24kc.ipk --force-checksum
    That gave all the weird results



  • @Jo-Kritzinger Oh, right, it was my own mistake. It should be src/gz reboot_packages http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/packages not src/gz reboot_packages http://downloads.lede-project.org/snapshots/packages/mips_24kc/packages -- just change mips to mipsel.



  • @WereCatf OK, tried. Still an issue. I modified the line added to disftfeeds to reflect mipsel and ran the opkg update. Still got 100's of these type of messages

    Package zoneinfo-southamerica version 2016j-1 has no valid architecture, ignoring.
    Package zope-interface version 4.3.2-1 has no valid architecture, ignoring.
    Package zsh version 5.2-1 has no valid architecture, ignoring.
    

    but it ended with

    Updated list of available packages in /var/opkg-lists/omega2_core
    Downloading http://repo.onion.io/omega2/packages/core/Packages.sig
    Signature check passed.
    Downloading http://repo.onion.io/omega2/packages/base/Packages.gz

    Then
    opkg install mjpg-streamer_r182-8_mipsel_24kc.ipk --force-checksum
    That resulted in
    Illegal instruction

    Time for a factory reset?



  • @WereCatf OK! Downloaded and installed following a reboot of the Omega. Seems the Omega was in an odd state.



  • This post is deleted!


  • @Jo-Kritzinger By the by, once you have launched mjpg_stream, is there a neat way of stopping it or is it just Ctrl-C that results in

    setting signal to stop
     i: cleaning up ressources allocated by input thread
    force cancellation of threads and cleanup resources
    Segmentation fault
