1. Cut video file into a smaller clip You can use the time offset parameter (-ss) to specify the start time stamp in HH:MM:SS.ms format while the -t parameter is for specifying the actual duration of the clip in seconds. ffmpeg -i input.mp4 -ss 00:00:50.0 -codec copy -t 20 o...
一个由|分隔原始信号和反射作用的指代延迟时间的字符串列表,单位是微秒(milliseconds)。每个延迟允许范围(0-90000.0),默认为1000 decays 设置一个由|分隔的反映信号响度衰减值的列表,每个衰减值范围是(0-1.0),默认为0.5. aecho例子 让一个声音听起来像两倍 aecho=0.8:0.88:60:0.4 如果延迟十分短,那听起来像一...
That leads me to think that NSVf[12-15] might be the * file length in milliseconds. * Let's try that: * for f in *.nsv; do HTIME="$(od -t x4 "$f" | head -1 | sed 's/.* //')"; echo "'$f' $((0x$HTIME))s = $((0x$HTIME/1000/60)):$((0x$HTIME/10...

time_base rational number Set codec time base. It is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented. For fixed-fps content, timebase should be "1 / frame_rate" and timestamp increments should be identically 1. g integer (encoding,video) Set...
