ffmpeg Error: Too many packets buffered for output stream

Question

我正在开发一个使用 ffmpeg 的电子应用程序，我正在 win10 机器上开发，所以我使用命令提示符并且我已经安装了 npm 包 'ffmpeg-ffprobe-static'。我可以通过像这样调用包在终端中运行 ffmpeg 命令：

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 命令可以将两个 flac 文件组合成一个 mp3 文件，在我遇到这个错误之前一直运行良好：

[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 歌曲中有些东西可以在 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 - Billy Martin - Phillie Dog.flac" -i "G:\RenderTune broken files\broken flac example - 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

如果我运行与其他 flac 文件使用相同的命令，它工作正常：

ffmpeg.exe -i "G:\RenderTune broken files\working flac example. Gossip.flac" -i "G:\RenderTune broken files\working flac example. 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"

我已经尝试像许多帖子建议的那样将 -max_muxing_queue_size 9999 添加到我的 ffmpeg 命令中，但这并没有解决它，有人知道如何防止这个错误吗？

[编辑] 我尝试了其中一种已发布的解决方案：

ffmpeg.exe -y -i "G:\RenderTune broken files\working flac example. Gossip.flac" -i "G:\RenderTune broken files\working flac example. 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"

因不同的错误而崩溃：

[libmp3lame @ 000002453725f3c0] Queue input is backward in time.9x

Answer 1

专辑封面图片出现问题。通过向 concat 过滤器输出添加输出标签来忽略它，并且仅 mapping 串联音频：

ffmpeg.exe -y -i "G:\RenderTune broken files\working flac example. Gossip.flac" -i "G:\RenderTune broken files\working flac example. 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 default stream selection 将选择过滤器输出加上损坏的图像，从而导致您的问题中显示的错误。

Answer 2

这解决了我的问题（后文提到了损坏的标志，但这很容易通过重新编码或调整设置来解决）。

Linux 21.04，ffmpeg ffmpeg 版本 4.2.3

文件示例：here（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
