On Ubuntu 16.04 "xargs: run_command: No such file or directory"

[spamrefuse]

Hi,

I'm running the video script on Ubuntu LTS 16.04 with bash, using the "master.zip" as of yesterday. Something is wrong with "xargs" and possibly "ffmpeg":

$ ./gear360video.cmd -s -t ./tmp/ 360.mp4

The xargs line in the script is this:

if [ -z "${USEPARALLEL+x}" ]; then
  # No parallel
  find $FRAMESTEMPDIR -type f -name '*.jpg' | xargs -Ipanofile run_command "$DIR/gear360pano.cmd" -r -m -o "$OUTTEMPDIR" "panofile" "$PTOTMPL"
else

The ffmpeg error occurs in this line:

run_command ffmpeg -y -f image2 -i "$OUTTEMPDIR/$IMAGETMPLENC" -r "${SRCFPSSTR}" -s "${SRCVIDEOSIZE}" $FFMPEGQUALITYENC "$OUTTEMPDIR/$TMPVIDEO"`

Any ideas how this can be fixed?

Can you try the fix mentioned here?

Should be fixed now - I didn't check properly xargs "fix".

Note: I've noticed, as someone already noted, extra frames being added to video - I don't know yet why it happens. Every second extra 6 frames are added.

Please reopen if problem persists.
