问题描述

去年我问了这个问题.我解决了我遇到的问题,并实现了将图像与视频(而不是两个图像)合并的相同逻辑.它正在Android上运行.

I asked this question last year. I resolved the issue I had and I implemented the same logic for merging an image with a video, instead of two images. This is running on Android.

这是我当前正在使用的命令:

Here is the command I'm using currently:

"-i", mFilePath, "-i", drawingPath, "-filter_complex", "[0:v]scale=iw*sar:ih,setsar=1,pad='max(iw\\,2*trunc(ih*47/80/2))':'max(ih\\,2*trunc(ow*80/47/2))':(ow-iw)/2:(oh-ih)/2[v0];[1:v][v0]scale2ref[v1][v0];[v0][v1]overlay=x=(W-w)/2:y=(H-h)/2[v]", "-map", "[v]", "-map", "0:a", "-c:v", "libx264", "-preset", "ultrafast", "-r", outputFPS, outputPath}

47/80/2 是通过获取设备的屏幕尺寸- 1128 x 1920 来计算的.

47/80/2 is calculated by getting a device's screen dimensions - 1128 x 1920.

在某些设备上运行该视频时,它会导致无法播放视频.

When running this on certain devices, it results in an unplayable video.

但是运行以下命令可以很好地工作:

But running the following command works perfectly fine:

"-i", mFilePath, "-crf", "18", "-c:v", "libx264", "-preset", "ultrafast", outputPath};

我认为问题在于正在应用过滤器?

I think the issue is with the filter being applied?

我比较了在两个不同的设备上运行第一个命令的情况.

I compared running the first command on two different devices.

  • 在第一台设备(三星J7 Pro)上,我能够成功运行命令并随后播放视频.我在两个设备上都测试了输出,并且可以正常工作.
  • 在第二台设备(Sony Xperia Tablet Z)上,我能够成功运行命令,但无法播放视频.我在这两种设备上测试了输出,但都不在其中任何一个上播放.它确实可以在我的计算机上播放.

我将原始视频与不运行的视频进行了比较,而没有过滤器的视频进行了比较,唯一的区别是,我无法访问的配置文件是 Baseline@L4.2 ,而没有过滤器配置文件的是 Baseline@L4.0 .原始视频配置文件是 High@L4.0 .

I compared the original video with the one not working and the one without a filter and the only difference I could find is that the one that is not working profile is Baseline@L4.2 and the one without a filter profile is Baseline@L4.0. The original video profile is High@L4.0.

此处是所有视频.原始的,一个没有过滤器的(有效)和一个有过滤器的(无效).

Here are all the videos. The original, the one without a filter (working) and the one with the filter(no working).

我不知道为什么会这样?任何帮助将不胜感激.

I have no idea why this is happening? Any help would be appreciated.

这是请求的实际日志:

"-i", "/storage/emulated/0/Android/data/com.my.package/files/CameraTemp/2020_05_24_09_17_53.mp4", "-i", "/storage/emulated/0/Android/data/com.my.package/files/MyVideos/tempShapes.png", "-filter_complex", "[0:v]scale=iw*sar:ih,setsar=1,pad='max(iw\\,2*trunc(ih*47/80/2))':'max(ih\\,2*trunc(ow*80/47/2))':(ow-iw)/2:(oh-ih)/2[v0];[1:v][v0]scale2ref[v1][v0];[v0][v1]overlay=x=(W-w)/2:y=(H-h)/2[v]", "-map", "[v]", "-map", "0:a", "-c:v", "libx264", "-preset", "ultrafast", "-r", "30", "/storage/emulated/0/Android/data/com.my.package/files/MyVideos/video with line.mp4"

推荐答案

我猜这些设备拒绝播放4.0级以上的内容.1920x1128将超过4.0级.设置 -level 将无济于事,因为它仍然会超过该级别,并且您会收到类似于 frame MB size(120x69)>的警告.上限(8192).

I guess these devices refuse to play anything over level 4.0. 1920x1128 will exceed level 4.0. Setting -level won't help because it will still exceed the level and you'll get a warning similar to frame MB size (120x69) > level limit (8192).

有关回放支持的详细规范通常很难找到(如果有的话),但是

Detailed specifications regarding playback support are often hard to find, if they are available at all, but Samsung only states that the Galaxy J7 Pro "Video Playing Resolution: FHD (1920 x 1080)@60fps". I didn't check the Sony Xperia Tablet Z, but since it is from 2012 I wouldn't doubt it is in a similar situation.

这不是您要找的答案,但您可能会被限制为1920x1080或更小.当然我可能是错的.如果您可以找到更详细和有用的信息,请确保使用的是最新的可用操作系统版本,并参考设备规格.

This wasn't the answer you were looking for, but you may be limited to 1920x1080 or lower. Of course I may be wrong. Make sure you're using the latest available OS version and refer the device specs if you can find something more detailed and informative.
