cut a part from an mp4 video with no wreckage using ffmpeg and php
19 janvier 2017, par NegroNeroI use this cmd below to cut a part from an MP4 video :
ffmpeg -ss 00:00:10.500 -i {$ffmpeg_mp4_vinput} -t 00:00:17.430 {$ffmpeg_mp4_voutput} 2>&1
and
ffmpeg -ss 00:00:10.500 -i {$ffmpeg_mp4_vinput} -to 00:00:17.430 {$ffmpeg_mp4_voutput} 2>&1
and
ffmpeg -ss 00:00:10.500 -i {$ffmpeg_mp4_vinput} -t 7 {$ffmpeg_mp4_voutput} 2>&1
All those cmds are called by
exec()
php function, they all work fine withSAME
result.Problem is when I cut a video with one of those commands, I get a video with long video from what I set in from-to in the commands. For example I get 1 second before and more than 2+ seconds after.
Is there something missed out from the commands ?

How to specifiy ffmpeg creation time as the segment creation time
6 novembre 2023, par şahinI am using ffmpeg to create video records from streams. Ffmpeg command creates segments from the streams. Think that 24 hours record with ffmpeg and divide it into 1 hour segments so i have 24 video records at the end. Problem is that ffmpeg always put the first segment creation time to the following ones meta data. Last video has the first video creation time. How to create segments with the time they created ?


My ffmpeg commands


ffmpeg -y -buffer_size 500000 -thread_queue_size 128 -i $1 -metadata title=$2 -metadata creation_time="`date +%F` `date +%T`" -c:a copy -c:v copy -f segment -segment_time 01:00:00 segment_format mp4
