• ffmpeg - invalid duration

  22 septembre 2016, par OmidAntiLong

  For a project I’m working on I have a small bash script that loops over an input csv file of timecodes, and uses ffmpeg to create screenshots of a given film at each timecode. The csv file is in the format hh:mm:ss,id - it looks like this (extract)

  00:00:08,1
  
  00:00:49,2
  
  00:01:30,3
  
  00:02:38,4
  
  00:03:46,5
  
  00:04:08,6
  
  00:04:26,7
  
  00:04:37,8
  
  00:04:49,9
  
  00:05:29,10
  
  00:05:52,11
  
  00:06:00,12
  
  00:06:44,13
  
  00:07:49,14
  
  00:08:32,15
  
  00:09:28,16
  
  00:10:17,17
  
  00:10:44,18
  
  00:11:48,19
  
  00:12:07,20

  I’ve used it without issue in the past, but today I’ve come to update some of the films and I’m getting a weird issue where ffmpeg is complaining that my input timecode is invalid, despite being in the right format.

  The new input csv files are the same format as the old ones, but it seems like every so often ffmpeg drops the hours from the hh:mm:ss timestamp. If I comment out the ffmpeg line, everything prints to the terminal as expected (but obviously I get no screenshots).

  This is my loop code :

  while read code a
  
  do
  
    echo $code
  
    f="$(printf "%03d" $i)"
  
  
  
    ffmpeg -loglevel error -y -ss $code -i $FILM -vframes 1 -q:v 2 $OUTPUT/$f.jpg
  
  
  
    ((i++))
  
  done < $INPUT

  I’ve tried all sorts, including padding the csv with extra 0s - which works until the hours tick over to 01.

  

  Does anyone have any ideas ? I’m scratching my head.

  Cheers

• How do I fix HTTP 404 error message using FFMPEG command ? [on hold]

  18 décembre 2018, par Noob

  I am trying to download a video from this site (https://ffmovies.ru/film/night-school.kk6y4/16qmpp) and have tried using ffmpeg but it always returns an "HTTP Error 404 Forbidden." I’ve also tried using the wget command to consolidate all the ts files but that didn’t work either (I get the same error message). I am not on expert in this and was hoping someone out there can help me fix this problem. Here is the ffmpeg code that I inputed :

  ffmpeg -i https://cdn.mcloud.to/stream/sf:i0:q2:h5:p23:l1/vtYB9rGpyklG1sxXqgdmXg/1545238800/g/9/b/pj11w4/hls/480/480.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

  I have also attached a picture of the error message for reference. I really appreciate someone showing me what I am doing wrong.

  Cheers.
