编译安装ffmpeg，如果已经安装，请跳过此步骤。
[[email protected] ~]# wget https://github.com/FFmpeg/FFmpeg/archive/n3.1.10.tar.gz [[email protected] ~]# tar xf n3.1.10.tar.gz [[email protected] ~]# cd FFmpeg-n3.1.10/ [[email protected] FFmpeg-n3.1.10]# ./configure --disable-debug && make -j 8 && make install [[email protected] FFmpeg-n3.1.10]# echo $? 0
开始使用ffmpeg，合并视频
FFmpeg concat 视频合并
这种方法成功率很高，也是最好的。先创建一个文本文件list_720p.txt
[[email protected] ~]# cat list_720p.txt file ‘Cry_Cry_T-ara_720p.flv‘ file ‘Cry_Cry_T-ara_720p.flv‘ file ‘Cry_Cry_T-ara_720p.flv‘ file ‘Cry_Cry_T-ara_720p.flv‘ file ‘Cry_Cry_T-ara_720p.flv‘ [[email protected] ~]#
然后： ffmpeg -f concat -i ./list_720p.txt -ccopy Collection_720p.mp4 如果 list_720p.txt 里面的视频文件内容不一样，比如音视频编码不一样，帧率码流分辨率不一样， 还想合成一个文件，那就要设置相关参数了。 或者可以这样，设置视频编码，设置音频编码，设置帧率(还可以设置码流) ffmpeg -f concat -i ./list_720p.txt -vcodec h264 -acodec aac -r 30 Collection_720p.mp4
