Split video file. FFmpeg

Operating systems : Windows, Linux

Split video file by ffmpeg:

There are two ways how to split video files by ffmpeg. The first one is good in itself, more than that - it is faster, but sometimes creates output files with certain flaws. So for those cases there is the second way of splitting video files: it is considerably slower, the output files are bigger, but it seems they are always of the same quality level as input files used.

Way : 1

ffmpeg -ss <start> -t <duration> -i in1.avi -vcodec copy -acodec copy out1.avi

Way : 2

ffmpeg -ss <start> -t <duration> -i in1.avi -sameq out1.avi

- <start> - the beginning of the part of a video ffmpeg is to cut out. Format: 00:00:00 - hours:minutes:seconds - hh:mm:ss

- <duration> - the duration of the part of a video ffmpeg is to cut out. Format: 00:00:00 - hours:minutes:seconds - hh:mm:ss

Examples

ffmpeg -ss 01:19:00 -t 00:05:00 -i in1.avi -vcodec copy -acodec copy out1.avi

ffmpeg -ss 01:19:00 -t 00:05:00 -i in1.avi -sameq out1.avi

- ffmpeg cuts out a part of the video file starting from 1 hour 19 minutes 0 seconds. The duration of the video sequence cut out is 5 minutes 0 seconds.

Windows console applications. Multimedia

 

MPlayer : FFmpeg Media players appeared long ago, but their heyday began with the mass spread of personal computers powerful enough to play video files. This coincided with the mass spread of operating systems and other software with graphical user interface. However, a program with a graphical user interface is dualistic in its nature: there is a code responsible for graphical user interface, for the appearance and there is a code - for performing the task the given application has been created for in the first place. Both code complexes consume system resources, their response time to user actions makes up certain amount of waiting time. And in cases or concepts when appearance is taken as less important - less important to the point of sparing or almost sparing to employ it - console applications, among others, appear. Moreover, the segmentation of the GUI and of the engine makes it easier to change the graphical user interface or perform complex automated operations. The scheme is implemented for media players for Windows as well. MPlayer, for instance, in its usual form is a console application, starting up quickly, having fast response to user actions, consuming system resources almost entirely for its immediate task. And on this basis if desired, one or another graphical interface may be added for creating, all in all, a new application. MPlayer - / home page / Console media player for Windows.
