替换模板视频图片的原理
理解fps
.\ffmpeg-20180331-be502ec-win64-static_ffmpeg.exe -i offBM-1080-720-BackAudio_320kbpsmale_5.mp4 -r 1 -f image2 ffmpeg_temp/%05d.png
视频转图片
替换结果图片集合中的指定图片
再转回视频
关键点在于fps的计算，实现无缝衔接效果
从应用角度而非视频质量角度要考虑：
本地保存的帧图片的空间消耗

ffmpeg Documentation http://ffmpeg.org/ffmpeg.html
You can extract images from a video, or create a video from many images:
For extracting images from a video:
ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg
This will extract one video frame per second from the video and will output them in files named foo-001.jpeg, foo-002.jpeg, etc. Images will be rescaled to fit the new WxH values.
If you want to extract just a limited number of frames, you can use the above command in combination with the -frames:v or -t option, or in combination with -ss to start extracting from a certain point in time.
For creating a video from many images:
ffmpeg -f image2 -framerate 12 -i foo-%03d.jpeg -s WxH foo.avi
The syntax foo-%03d.jpeg specifies to use a decimal number composed of three digits padded with zeroes to express the sequence number. It is the same syntax supported by the C printf function, but only formats accepting a normal integer are suitable.
When importing an image sequence, -i also supports expanding shell-like wildcard patterns (globbing) internally, by selecting the image2-specific -pattern_type glob option.
For example, for creating a video from filenames matching the glob pattern foo-*.jpeg:
ffmpeg -f image2 -pattern_type glob -framerate 12 -i 'foo-*.jpeg' -s WxH foo.avi
0.1 video frame per second

FFmpeg FAQ https://ffmpeg.org/faq.html#How-can-I-concatenate-video-files_003f
3.14 How can I concatenate video files?
There are several solutions, depending on the exact circumstances.
3.14.1 Concatenating using the concat filter
FFmpeg has a concat filter designed specifically for that, with examples in the documentation. This operation is recommended if you need to re-encode.
3.14.2 Concatenating using the concat demuxer
FFmpeg has a concat demuxer which you can use when you want to avoid a re-encode and your format doesn’t support file level concatenation.
3.14.3 Concatenating using the concat protocol (file level)
FFmpeg has a concat protocol designed specifically for that, with examples in the documentation.
A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow one to concatenate video by merely concatenating the files containing them.
Hence you may concatenate your multimedia files by first transcoding them to these privileged formats, then using the humble cat command (or the equally humble copy under Windows), and finally transcoding back to your format of choice.
ffmpeg -i input1.avi -qscale:v 1 intermediate1.mpg ffmpeg -i input2.avi -qscale:v 1 intermediate2.mpg cat intermediate1.mpg intermediate2.mpg > intermediate_all.mpg ffmpeg -i intermediate_all.mpg -qscale:v 2 output.avi
Additionally, you can use the concat protocol instead of cat or copy which will avoid creation of a potentially huge intermediate file.
ffmpeg -i input1.avi -qscale:v 1 intermediate1.mpg ffmpeg -i input2.avi -qscale:v 1 intermediate2.mpg ffmpeg -i concat:"intermediate1.mpg|intermediate2.mpg" -c copy intermediate_all.mpg ffmpeg -i intermediate_all.mpg -qscale:v 2 output.avi
Note that you may need to escape the character "|" which is special for many shells.
Another option is usage of named pipes, should your platform support it:
mkfifo intermediate1.mpg mkfifo intermediate2.mpg ffmpeg -i input1.avi -qscale:v 1 -y intermediate1.mpg < /dev/null & ffmpeg -i input2.avi -qscale:v 1 -y intermediate2.mpg < /dev/null & cat intermediate1.mpg intermediate2.mpg |\ ffmpeg -f mpeg -i - -c:v mpeg4 -c:a libmp3lame output.avi
3.14.4 Concatenating using raw audio and video
Similarly, the yuv4mpegpipe format, and the raw video, raw audio codecs also allow concatenation, and the transcoding step is almost lossless. When using multiple yuv4mpegpipe(s), the first line needs to be discarded from all but the first stream. This can be accomplished by piping through tail as seen below. Note that when piping through tail you must use command grouping, { ;}, to background properly.
For example, let’s say we want to concatenate two FLV files into an output.flv file:
mkfifo temp1.a
mkfifo temp1.v
mkfifo temp2.a
mkfifo temp2.v
mkfifo all.a
mkfifo all.v
ffmpeg -i input1.flv -vn -f u16le -c:a pcm_s16le -ac 2 -ar 44100 - > temp1.a < /dev/null &
ffmpeg -i input2.flv -vn -f u16le -c:a pcm_s16le -ac 2 -ar 44100 - > temp2.a < /dev/null &
ffmpeg -i input1.flv -an -f yuv4mpegpipe - > temp1.v < /dev/null &
{ ffmpeg -i input2.flv -an -f yuv4mpegpipe - < /dev/null | tail -n +2 > temp2.v ; } &
cat temp1.a temp2.a > all.a &
cat temp1.v temp2.v > all.v &
ffmpeg -f u16le -c:a pcm_s16le -ac 2 -ar 44100 -i all.a \
-f yuv4mpegpipe -i all.v \
-y output.flv
rm temp[12].[av] all.[av]
