How can I get video duration in seconds?
what I've tried:
ffmpeg -i file.flv 2>&1 | grep "Duration"
Duration: 00:39:43.08, start: 0.040000, bitrate: 386 kb/s
mediainfo file.flv | grep Duration
Duration : 39mn 43s
this what close, but it's not so accurate, 2383 is 39.71 minutes
ffmpeg -i file.flv 2>&1 | grep "Duration"| cut -d ' ' -f 4 | sed s/,// | sed 's@\..*@@g' | awk '{ split($1, A, ":"); split(A[3], B, "."); print 3600*A[1] + 60*A[2] + B[1] }'
2383
回答1:
2383 is correct. There are 60 seconds in a minute, not 100. 43/60 = .71

回答2:
There is a better, faster and low CPU/HD footprint solution, just with mediainfo without relying into awk:
mediainfo --Inform="General;%Duration%" input.m4v
回答3:
Using awk
mediainfo file.flv | awk '/Duration/ {print $3*60+$4}'
2383
ffmpeg -i file.flv 2>&1 | awk '/Duration/ {split($2,a,":");print a[1]*3600+a[2]*60+a[3]}'
2383.08
To handle different formats, use this:
cat file
Duration : 39mn 43s
Duration : 39s 43ms
awk '/Duration/ {for (i=3;i<=NF;i++) if ($i~/[0-9]+mn$/) s+=$i*60; else if ($i~/[0-9]+s$/) s+=$i; else if ($i~/[0-9]+ms$/) s+=$i/10; print s;s=0}' file
2383
43.3

Its Working for me try it :)
$duration = shell_exec("ffmpeg -i \"". $input . "\" 2>&1");
preg_match("/Duration: (\d{2}:\d{2}:\d{2}\.\d{2})/",$duration,$matches);
$time = explode(':',$matches[1]);
$hour = $time[0];
$minutes = $time[1];
$seconds = round($time[2]);
$total_seconds = 0;
$total_seconds += 60 * 60 * $hour;
$total_seconds += 60 * $minutes;
echo $total_seconds += $seconds;

You can use
ffprobe -v quiet -print_format xml -show_format -show_streams inputfile.flv
it will return an xml like this
<?xml version="1.0" encoding="UTF-8"?>
<ffprobe>
<streams>
<stream index="0" codec_name="h264" codec_long_name="H.264 / AVC / MPEG-4 AVC /

</stream>
</streams>
<format filename="inputfile.flv" nb_streams="2" format_name="mov,mp4,m4a,3gp,3g2,mj2" format_long_name="QuickTime / MOV" start_time="-0.021333" duration="3.942000" size="2194901" bit_rate="4454390">

<tag key="compatible_brands" value="isomiso2avc1mp41"/>
<tag key="encoder" value="Lavf54.63.100"/>
</format>
</ffprobe>
then filter by the video stream i.e. usually that with attribute index ="0" and get the value of the attribute "duration" which is already in seconds.
回答6:
I used this in php:
exec('mediainfo --Inform="General;%Duration%" ' . $filename, $output);
// type 86 sec = 85962.695312
$durationInSec = ceil(ceil($output[0])/1000);
回答7:
If you have ffmpeg, you should also have ffprobe. It outputs information to STDOUT in a series of key=value pairs, and gives the duration in seconds by default (you have to use the -sexagesimal
option if you want hh:mm:ss):
ffprobe -show_format file.mp4 | grep -F duration | cut -d= -f2
回答8:
In case you have ffmpeg
installed, most likely you would have ffprobe
installed too.
ffprobe -i file.mp4 -show_format -v quiet | sed -n 's/duration=//p' | xargs printf %.0f
The command will return an integer value.
Output example:
190
