• Bash Script using formatted date string in FFMPEG command

  30 juin 2024, par coco

  In my bash (zsh) script, I am receiving a string that represents a Unix epoch, like :

  


  myTimestamp="1719742786"


  


  I want to change that date into a formatted string, and then store it in a variable so it can be used in an upcoming ffmpeg script. I'm doing it this way :

  


  theDate=$(date -u -r "$myTimestamp" "+%b %d, %H:%M:%S")
echo "$theDate"


  


  which prints to my screen what I want :

  


  Jun 30, 06:19:48


  


  but when I try to use this variable in my ffmpeg script, I get errors :

  


  ffmpeg -y -i "$file" -vf \
        "drawtext=text='$theDate':fontcolor=gray:fontsize=$fontSize:x=$width:y=$height:" \
        "$output"


  


  Note that if I change out '$theDate' in the script (to something like '$myTimestamp'), I do not get errors.

  


  What I do get, along with Error initializing filters, is this (possibly important ?) error :

  


  


  Both text and text file provided. Please provide only one

  


  


• Go lang, exec.Command() /, \(escape mark), string processing [closed]

  18 novembre 2024, par nojob

  I am using go lang and want to use exec.Command() function.
But having problem processing the string of command

  


  Here is my code snippet.

  


  cmd := exec.Command("cmd", "/k", "start", "ffplay", "-f", "dshow", "-i", `video=@device_pnp_\\?\usb#vid_0fd9&pid_0094&mi_00#6&012aa09&0&0000#{65e00ee0-8f44-77d0-a3f5-00a0c9223000}\global`)


  


  I really have no idea even I read some articles about `, /, .

  


  cmd := exec.Command("cmd", "/k", "start", "ffplay", "-f", "dshow", "-i", "video=Elgato Facecam MK.2")


  


  And this works. just video=Elgato Facecam MK.2
Actually as I know, video"Elgato Facecam MK.2" is correct, but I don't know why this works.

  


  Anybody please ?

  


• phplondon conference 2008

  9 juin 2010, par Mikko Koppanen — Everything else, Imagick, PHP stuff, phplondon08

  To summarize it : I had fun My conference preparations started about two weeks before the conference. The PHPLondon fellows (Paul, Matt and Richard) asked me to do a small presentation about Imagick at the pre-conference social event. The presentation I assembled ended up being a little over two hours, give or take. The hardest part was to trim down from two hours to about 40 minutes (I didn’t want to bore the people with too many code examples). The slides are available at http://valokuva.org/talks if you need them for some reason.

  My conference day was pretty hectic from the beginning to the end. I gave a few demos about the products that we represent and the moment I opened my mouth for the first time people started leaving the room. I hope that it had something to do with the “My Framework is better than yours ?” talk starting at the same time

  I met quite a lot of new people at the conference and of course it was nice to see the familiar faces from other conferences and PHPLondon meetings. I was especially happy that I was able to answer the questions Nigel James had

  A huge thanks to the organizers for making this day possible !
