我试图弄清楚如何解决这些错误:

Error while filtering: Cannot allocate memory
Failed to inject frame into filter network: Cannot allocate memory
Error while processing the decoded data for stream #2:1

观察#1

如果我自己在流 #2:1 上运行以下命令:

ffmpeg -i video1c.flv -vcodec libx264 -acodec aac video1c.mp4

文件转换得很好，没有错误。

观察#2

在 video1c.flv(流 #2)上运行 MediaInfo 显示以下内容:

Format: Flash Video
Video Codecs: On2 VP6
Audio Codecs: Nellymoser

任何帮助将不胜感激解决此错误。

更新 #1

我已尝试按要求将过滤器图分成两部分，但收到相同的错误:

Error while filtering: Cannot allocate memory
Failed to inject frame into filter network: Cannot allocate memory
Error while processing the decoded data for stream #1:1

但是，我确实发现了一些东西，如果我尝试使用 VLC 媒体播放器打开上面提到的流 #1:1 (video1b.flv)，我可以听到音频文件但看不到视频，并且收到以下错误消息:

No suitable decoder module:
VLC Does not support the audio or video format "undf".
Unfortunately there is no way for you to fix this.

更新 #2

上述错误与 ffmpeg 的 32 位版本有关。我切换到 64 位机器，现在正在运行 64 位 ffmpeg 版本 ffmpeg-20180605-b748772-win64-static。

现在我不再收到以下错误:

Error while processing the decoded data for stream #1:1

但是，我有一个新的错误。运行大约一个小时后，我收到以下错误:

av_interleaved_write_frame(): Cannot allocate memory
[mp4 @ 000000000433f080] Application provided duration: 3327365388930198318
/ timestamp: 17178820096 is out of range for mov/mp4 format

我还尝试首先按照建议重新混合所有文件并使用这些文件运行上述命令，但这没有帮助。我仍然得到同样的错误。

Answer 1

尝试使用不同过滤器图中的音频和视频

ffmpeg

-i "video1a.flv"
-i "video1b.flv"
-i "video1c.flv"
-i "video2a.flv"
-i "video3a.flv"
-i "video4a.flv"
-i "video4b.flv"
-i "video4c.flv"
-i "video4d.flv"
-i "video4e.flv"
