闲鱼发送二维码

闲鱼发送二维码

闲鱼不支持发送二维码图片，即使本地显示发送成功，对方收到的只是一个违规图片的提醒。

所以大多数人都是选择录屏，然后将录制的视频发送给对方。

在图片较多的情况下，录屏就很麻烦，因为视频有长短限制，录制起来很耗时。

于是尝试使用ffmpeg将图片转成视频:

ffmpeg -r 25 -loop 1 -i input.png -pix_fmt yuv420p -vcodec libx264 -vframes 250 -r 25 -t 10 output.mp4

ffmpeg -framerate 1 -f image2 -loop 1 -i images/%d.png -vcodec libx264 -pix_fmt yuv420p -r 25 -t 10 -y output.mp4

将转好的视频发送给对方后，有两个问题：

  • 对方仍然收到“图片涉嫌违规”的提示
  • 视频被压缩，很糊，二维码、图片都难以识别

于是尝试使用文件路径替换解决这两个问题。

思路也很简单，就是在生成视频封面、压缩视频后将文件替换。
