我正在使用 ffmpeg 连接一组视频,方法如下:
ffmpeg -y -f concat -safe 0 -i ./vidlist.txt -c:a aac -c:v libx264 -r 30 ./out.mp4
但是该命令在此过程中会将其打印到控制台:
[matroska,webm @ 0000018df0fd6a40] Element at 0x234559 ending at 0x234723 exceeds containing master element ending at 0x23454d

[matroska,webm @ 0000018df0fd6a40] Auto-inserting h264_mp4toannexb bitstream filter
视频看起来不错,但音频偶尔会在短时间内丢失,因此会跳过短时间的音频。
