  avfilter/af_channelmap : fix mapping if in_channel was a string but out_channel was not specified
  In this case in_channel_idx was never set and the default 0 was used.
  
  Suprisingly no one noticed that the respective fate test output was wrong.

  lavc/qsvenc : add support for oneVPL string API
  A new option -qsv_params <str> is added, where <str> is a :-separated
  
  list of key=value parameters.
  Example :
  
  $ ffmpeg -y -f lavfi -i testsrc -vf "format=nv12" -c:v h264_qsv -qsv_params
  
  "TargetUsage=1:GopPicSize=30:GopRefDist=2:TargetKbps=5000" -f null -

• Zsh script using formatted date string in FFMPEG command [closed]

  1er juillet 2024, par coco

  In my 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

  


  


  Note I am on MacOS v14.5. The man date mentions The date utility is expected to be compatible with IEEE Std 1003.2 (“POSIX.2”).  With the exception of the -u option, all options are extensions to the standard.

  


  My full script :

  


  #!/bin/zsh
outDir="printed"
width=200
height=650
fontSize=95

for file in initial/*.png; do
    filename=$(basename "$file")
    prefix="${filename%.*}"
    theDate=$(date -u -r "$prefix" "+%b %d, %H:%M:%S")
    output="$outDir/$filename"

    echo "$theDate"

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

done
exit
