• basetime for strftime segment filename template

  12 mai 2015, par basin

  I have a big mp3 file, which I started recording at 17:24. Trying to split into 2 minute segments :

  ffmpeg -y -i test.mp3 -map 0 -c copy -f segment -segment_time 120 -reset_timestamps 1 -strftime 1 '1/test-%H-%M.mp3'

  Need segment names like test-17-24.mp3, test-17-26.mp3, ..., Actual first segment is named as current time, no extra segments created

  11 mai 2015, par Desipicforu Blogspot

  I am using this command in ffmpeg

     ffmpeg -i test.flv -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s 640x360 -movflags test.mp4 2>&1

  But i am getting this

   string(42) "At least one output file must be specified"

  updated :-

  php code :-

   $output ='{ffmpeg-cmd} -i {input} -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s {ffmpeg-vsize} -threads 4 -movflags {output}.mp4 2>&1';

  I just installed ffmpeg correctly and I found out that you need this code to add subtitles :

  ffmpeg -i input.mp4 -f srt -i input.srt -c:v copy -c:a copy -c:s mov_text outfile.mp4

  So I downloaded a video and put it with the subtitles in the same folder on my desktop. Then I changed the code from above to this :

  ffmpeg -i CA.mp4 -f srt -i CA.srt -c:v copy -c:a copy -c:s mov_text outfile.mp4

  Console :

  ffmpeg -i CA.mp4 -f srt -i CA.srt -c:v copy -c:a copy -c:s mov_text outfile.mp4

  Do I have to place the file in another directory ?
