Question

我有一个python脚本，可以生成FFmpeg命令来连接视频片段。这是脚本：

        ffmpeg 
        -i /tmp/media/import-2020-Aug-19-Wednesday-08-08-26/temp_eba59811-bb5c-4e36-aa7d-b1731e70432c.mp4

        -i /tmp/media/import-2020-Aug-19-Wednesday-08-08-26/temp_d7371ecb-01df-4199-951f-336fa475998f.mp4

        -i /tmp/media/import-2020-Aug-19-Wednesday-08-08-26/temp_bf796e0d-135f-40fd-ab8e-4780da6973fd.mp4  
        -filter_complex

但是出现以下错误：Buffer queue overflow, dropping。我读到要解决此问题，我需要使用fifo，但我不知道应该将其放置在哪里。另外，似乎fifo仅适用于视频流。我将不胜感激！

在ffmpeg中串联时获取“缓冲区队列溢出，删除”
