ffmpeg 错误：为 output stream 缓冲的数据包过多

Question

I am working on an electron app that uses ffmpeg, I am developing on a win10 machine so I am using command prompt and I have installed the npm package 'ffmpeg-ffprobe-static'. 我可以通过调用 package 在终端中运行 ffmpeg 命令，如下所示：

C:\Users\martin\myproject\node_modules\ffmpeg-ffprobe-static>ffmpeg.exe -h
ffmpeg version 4.3 Copyright (c) 2000-2020 the FFmpeg developers
  built with gcc 9.3.1 (GCC) 20200621
....

我有一个 ffmpeg 命令将两个 flac 文件组合成一个 mp3 文件，该文件一直运行良好，直到我遇到此错误：

[mjpeg @ 0000022537ace640] bits 85 is invalid
Error while decoding stream #0:1: Invalid data found when processing input
Too many packets buffered for output stream 0:0.
[libmp3lame @ 0000022537ac3480] 3 frames left in the queue on closing
Conversion failed!

相同的命令适用于其他 flac 文件，因此这些 Billy Martin 歌曲的某些内容可以在 vlc 中完美播放，但会导致 ffmpeg 崩溃：

//running this command:


ffmpeg.exe -i "G:\RenderTune broken files\broken flac example\05 - Billy Martin - Phillie Dog.flac" -i "G:\RenderTune broken files\broken flac example\08 - Billy Martin - Stax.flac" -y -filter_complex concat=n=2:v=0:a=1 -c:a libmp3lame -b:a 320k "G:\RenderTune broken files\broken flac example\COMBINED_FILES.mp3"


//results in this output:
[mjpeg @ 0000022537ace640] bits 85 is invalid
Error while decoding stream #0:1: Invalid data found when processing input
Too many packets buffered for output stream 0:0.
[libmp3lame @ 0000022537ac3480] 3 frames left in the queue on closing
Conversion failed!

我在这里上传了损坏的flac文件： https://www.mediafire.com/folder/0v9hbfrap727y/broken+flac

如果我对其他 flac 文件运行相同的命令，它可以正常工作：

ffmpeg.exe -i "G:\RenderTune broken files\working flac example\5. Gossip.flac" -i "G:\RenderTune broken files\working flac example\6. Let The Children Play.flac" -y -filter_complex concat=n=2:v=0:a=1 -c:a libmp3lame -b:a 320k "G:\RenderTune broken files\working flac example\COMBINED_FILES.mp3"

我已经尝试将-max_muxing_queue_size 9999添加到我的 ffmpeg 命令中，就像许多帖子所建议的那样，但这并不能解决它，有人知道如何防止这个错误吗？

[编辑]我尝试了发布的解决方案之一：

ffmpeg.exe -y -i "G:\RenderTune broken files\working flac example\5. Gossip.flac" -i "G:\RenderTune broken files\working flac example\6. Let The Children Play.flac" -filter_complex "[0:a][1:a]concat=n=2:v=0:a=1[a]" -map "[a]" -c:a libmp3lame -b:a 320k "G:\RenderTune broken files\working flac example\COMBINED_FILES.mp3"

它因不同的错误而崩溃：

[libmp3lame @ 000002453725f3c0] Queue input is backward in time.9x
... lots of these [mp3 @ ..] messages

Answer 1

专辑封面图片有问题。 通过将 output label 添加到您的连接过滤器 output 并仅映射连接的音频来忽略它：

ffmpeg.exe -y -i "G:\RenderTune broken files\working flac example\5. Gossip.flac" -i "G:\RenderTune broken files\working flac example\6. Let The Children Play.flac" -filter_complex "[0:a][1:a]concat=n=2:v=0:a=1[a]" -map "[a]" -c:a libmp3lame -b:a 320k "G:\RenderTune broken files\working flac example\COMBINED_FILES.mp3"

否则，默认的 stream 选择将选择过滤器 output 加上损坏的图像，从而导致您的问题中显示的错误。

Answer 2

这解决了我的问题（后来谈到损坏的标志，但这很容易通过再次重新编码或通过设置进行修复）。

Linux 21.04, ffmpeg ffmpeg 版本 4.2.3

文件示例：这里（几天）

 ffmpeg -fflags +genpts -i peta_alien.ogv  -map 0 -c:v copy -c:a aac -max_muxing_queue_size 4000 peta_alien.avi
