本文介绍了ffmpeg混合排除顶级视频背景的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想混合两个视频，名为top.mp4的顶级视频与一些PNG文件相结合，但组合视频的背景是黑色的为什么？
I want to blend two videos, the top video named "top.mp4" was combined with some PNG files,but the combined video's background was black? why?
然后我尝试将top.mp4重叠在另一个视频（名为bottom.mp4，被android相机与QUALITY_480P捕获）
then i try to overlay the top.mp4 on another video (named bottom.mp4,was capture by android camera with QUALITY_480P)
但是当我使用Overlay过滤器时，我发现top.mp4不透明，在result.mp4上有黑色背景。
but when I use Overlay filter i find the top.mp4 was not transparent and have a black background on the result.mp4.
I尝试使用混合过滤器来组合top.mp4和bottom.mp4以排除top.mp4的黑色背景，但我不知道如何使用混合过滤器。
I try to use blend filter to combine top.mp4 and bottom.mp4 to exclude the top.mp4's black background , but i don't know how to use the blend filter.
这里是我的问题：
1.是否可以将PNG文件与视频相结合，视频具有透明背景？然后只需使用覆盖过滤器，结果.mp4将不会在top.mp4下面有一个黑色蒙版？
here is my question: 1.is it possible to combine PNG files to a video and the video has transparent background? and then just use overlay filter,the result.mp4 will not have a black mask under the top.mp4?
2.if 1是不可能的，如何混合顶部。 mp4和bottom.mp4以排除top.mp4的黑色背景
2.if 1 is impossible, how to blend top.mp4 and bottom.mp4 to exclude the black background of top.mp4

推荐答案
使用 -c：v png -pix_fmt rgba 生成PNG中的透明视频，并输出到 top.mov
Generate transparent video from PNGs by using -c:v png -pix_fmt rgba and output to top.mov
编辑：此命令从PNG中跳过中间的MOVs
Edit: this command skips the intermediate MOVs from PNGs
ffmpeg -i /storage/sdcard0/baishiMagic/temp/video1454412829452.mp4 -framerate 25 -i /storage/sdcard0/baishiMagic/magic/waterfall/waterfall/waterfall_%04d.png -framerate 25 -i /storage/sdcard0/baishiMagic/magic/waterfall/fish_isolate/fish_%04d.png -i /storage/sdcard0/frame.ts -filter_complex transpose=1,crop=480:640:0:40,overlay=0:0:0,overlay=-2:-2:0,overlay=0:0:0 -preset ultrafast -strict -2 -y /storage/sdcard0/baishiMagic/result.mp4
