I am trying to extract images in CentOS machine using ImageMagick's convert command as below:
convert -coalesce http://cdn.abcdf.com/p/f7/81/d3/40/f781d34031e68828eaasdwc937cf3f8.gif /mnt/temp/123.png
I am getting the following error:
convert: unable to open image `//cdn.adnxs.com/p/f7/81/d3/40/f781d34031e6882840eaa6dc937cf3f8.gif': No such file or directory # error/blob.c/OpenBlob/2701.
convert: no decode delegate for this image format `HTTP' # error/constitute.c/ReadImage/504.
convert: no images defined `/mnt/ephemeral2/creative_report/temp/123.png' # error/convert.c/ConvertImageCommand/3258
I tried reinstalling ImageMagick from source but it was of no use.
I resolved the issue by reinstalling IM and the missing libxml2-devel library. Below are the steps I followed:
1)cd (ImageMagick folder)
2)make uninstall
3)yum install tcl-devel libpng-devel libjpeg-devel ghostscript-devel bzip2-devel freetype-devel libtiff-devel libxml2-devel
4)wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick-6.9.9-0.tar.gz
5)tar xvfz ImageMagick-6.9.9-0.tar.gz
6)cd (the folder created)
7)./configure --prefix=/usr/local --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes
8)make clean
9)make
10)make install
On windows I would put double quotes around the path as it looks like it is breaking up the image path.
Your link is bad. My browser tells me it cannot find the server. In ImageMagick, you should read the input image first. So if you fix your URL, then
convert http://cdn.abcdf.com/p/f7/81/d3/40/f781d34031e68828eaasdwc937cf3f8.gif -coalesce /mnt/temp/123.png

I am using an embedded Linux system based on Yocto/Open Embedded Linux and the systemd-journald-remote program is missing.
When I look at the systemd recipe the program is mentioned. It seems like it is not compiled or added by default to the image. I understand how to add normal recipes but unfortunately I don't understand how to add such a "subpackage".
The Bitbake documentation is unfortunately overwhelming for a beginner like me. Can someone help me?
Create bbappend for systemd in your meta-layer with following path recipes-core/systemd/systemd_%.bbappend and:
PACKAGECONFIG_append = " \
microhttpd \
"
You can add it into your image .bb or .bbappend file with following parameter:
IMAGE_INSTALL += "systemd-journal-remote"
This will add systemd-journal-remote into your image. Install the image on your target board, log in to your target and configure the file /etc/systemd/journal-remote.conf.
Then, enable the service with systemctl enable systemd-journal-remote, and then restart it with systemctl restart systemd-journal-remote.

When running the above, I'm getting the following. It seems to run properly on other distributions. Not sure where to check next.
[Parsed_drawtext_0 # 0x2835480] Option 'draw' not found
[AVFilterGraph # 0x283f980] Error initializing filter 'drawtext' with args 'fontfile=/home/mysite/fonts/OswaldFont/Oswald-Bold.ttf: x=450: y=150: fontsize=152: fontcolor=0xAE0216#1: draw=if(gt(n,40),lt(n,300)): text=THANK YOU'
Error opening filters!
Additionally, this original command works fine in Ubuntu, but give the seen error when running in centOS.
According the the FFmpeg drawtext filter documentation:
draw
This option does not exist, please see the timeline system
This means you should use timeline editing instead.
To do that replace the draw='...' part of your command with:
enable=if(gt(n\,50)\,lt(n\,300))
You should also check:
FFmpeg versions on each machine. You might have an older version installed on Ubuntu, which supports the draw option, and a newer version on CentOS in which the option was removed.
if the font files exist
When I try to enable PostGis extension on my database I receive the following:
postgis=# CREATE EXTENSION postgis;
ERROR: could not load library "/usr/pgsql-9.3/lib/rtpostgis-2.1.so": libhdf5.so.6: cannot open shared object file: No such file or directory
I used find -name to find the files:
[root#digihaul3-pc /]# find -name rtpostgis-2.1.so
./usr/pgsql-9.3/lib/rtpostgis-2.1.so
[root#digihaul3-pc /]# find -name libhdf5.so.6
./usr/lib64/mpich2/lib/libhdf5.so.6
./usr/pgsql-9.3/lib/libhdf5.so.6
./usr/lib/mpich2/lib/libhdf5.so.6

it is for fordora 15. But i tried everything else and this actually fixed my issue and allowed me to install the postgis extentions. Doesn't take long to install.
Thinking Monkeys Post:
Checked for whether /etc/ld.so.conf has a reference to the path /usr/lib64/mpich2/lib.
by doing ldconfig -p | grep libhdf5.
Which did not output anything.
On checking that /etc/ld.so.conf had include ld.so.conf.d/*.conf.
Checked for the files in directory ld.so.conf.d. One of the conf file in include ld.so.conf.d was /etc/ld.so.conf.d/atlas-x8664.conf which contained /usr/lib64/atlas.
So I,
created a file called gdal.conf in the directory ld.so.conf.d.
Added the string /usr/lib64/mpich2/lib to the file.
Ran ldconfig.
Now, ldconfig -p | grep libhdf5 had the paths to llibhdf5 files.
After doing the above, postgis raster support installation went smoothly.
I am trying to load a graph in fuseki. The server is working as it should.
But when I try s-put inside the fuseki folder it tells me s-put is not found?!
hdeus$ ls
DEPENDENCIES config.ttl s-delete
Data fuseki s-get
LICENSE fuseki-server s-head
NOTICE fuseki-server.bat s-post
ReleaseNotes.txt fuseki-server.jar s-put
config-examples.ttl fuseki_config.ttl s-query
config-inf-tdb.ttl log4j.properties s-update
config-tdb.ttl pages s-update-form
hdeus$ sudo ./s-put http://localhost:3030/ds/data default Data/books.ttl
sudo: ./s-put: command not found
Any idea what the problem might be? I tried copy/paste s-put from the ls output but stil nothing... I am working in mac os X
Is the file executable? If you unpacked from the zip file, you need to set the s-* executable. Also, you need ruby installed.
Does anyone know how to extract teletext subtitles?
I have tried ffmpeg, it says
Invalid frame dimensions 0x0
CCExtractor, it says
"Missing ASF header. Abort
telxcc, it says
! Invalid TS packet header; TS seems to be misaligned
I have done a lot of research, but have no luck. Can anyone offer some help!
dvb_subtitles cannot be extracted with ffmpeg easily because is an image that overlays the original. Good explanation: https://stackoverflow.com/a/20887655/2119685
There is a way to extract the dvb_teletext, which normally includes the subtiltes too.
Install the next dependency:
sudo apt-get install libzvbi-dev
Then recompile from source ffmpeg with:
--enable-libzvbi
Good tutorial here on how to compile FFMPEG from source -https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
Then execute the next command to fetch the subtitles to a .srt file:
ffmpeg -txt_format text -i INPUT1 -an -vn -scodec srt test.srt
And voila, your .srt subtitles will be in test.srt
Did you try using gstreamer ? appsrc->tsdemux->fakesink. Make pipeline like this, and then get the PES data from fakesink callback.
