Odd X server error with ffmpeg
4 novembre 2013, par jhc
I am building a weather data acquisition system. One of the things I would like to do would be to animate the satellite data that is arriving every 15 minutes. In fact, I have already devised a script (calledanimate) that successfully joins eight hours worth of PNG images into an AVI video file. This runs fine when run manually from the terminal.Unfortunately, the same cannot be said when run from my (as in my user, not root) crontab.
Below is the cron job that I mentioned:
1,16,31,46 * * * * /home/daniella/bin/anim_all > /home/daniella/logs/anim_all.log 2>&1anim_allsimply calls animate for each distinct data product:#!/bin/bash set -x cd /home/daniella/data/imager rm -rf HRIT_MSG3_*.avi animate HRIT_MSG3_CTT animate HRIT_MSG3_IR108 animate HRIT_MSG3_VIS006 animate HRIT_MSG3_WV062And animate itself calls
ffmpeg.#!/bin/bash set -x cd /home/daniella/data/imager product=$1 hl="$product.8hl" declare -i i=0 for file in $(cat $hl); do link=$(printf "images%02d.png" $i) ln -sf $file $link i=$((i+1)) echo $i done ffmpeg -sameq -r 15 -i images%02d.png $product.avi rm -rf images*.pngJust to be clear, the .8hl file is simply a list of PNG file paths that refer to that last 8 hours of data. Since there is new data every 15 minutes, that is a text file with 32 lines. Finally, this is the error that is returned when examining anim_all.log (referred in the crontab) file.
+ animate HRIT_MSG3_CTT animate: unable to open X server `' @ animate.c/AnimateImageCommand/365. + animate HRIT_MSG3_IR108 animate: unable to open X server `' @ animate.c/AnimateImageCommand/365. + animate HRIT_MSG3_VIS006 animate: unable to open X server `' @ animate.c/AnimateImageCommand/365. + animate HRIT_MSG3_WV062 animate: unable to open X server `' @ animate.c/AnimateImageCommand/365.Please note that
anim_allworks fine, when called manually from the terminal. This error exists only when called by cron. I would imagine that this has to do with environment variables, but I have sourced my.bashrcinside the script to no prevail.EDIT - Investigating the
animate.cfile itself (see the full code here), at lines 365-368, there is this:if (display == (Display *) NULL) ThrowAnimateException(XServerError,"UnableToOpenXServer", XDisplayName(server_name)); (void) XSetErrorHandler(XError);In response, I have attempted to export the
$DISPLAYvariable to 127.0.0.0:0 in theanimatescript, but this has not worked. -

Aforge FFMpeg DLL Location Issue
4 novembre 2013, par Sam35I'm using AForge FFMPEG libraries for video compression in .Net.Currently I've put the ffmpeg & Aforge libraries in the location which the application(.exe) exists.
I need to put these libraries in a common place.i've tried to put these libraries inside system32 folder. It is not working.
Is there any ways to put the Aforge & FFMpeg Libraries in a common place other than application(.exe) directory?

Alternative to ffmpeg for dynamically creating video thumbnails
3 novembre 2013, par user763852The server hosting my website doesn't have ffmpeg and I am not allowed to install any additional extensions. Is there any other way I can make video thumbnails dynamically? Perhaps some kind of web service, where I pass the video file and as a result I get a picture file. I'm using php, by the way.
