Concat给出了闪烁的结果

Question

我真的不明白这一点;我使用ffmpeg concat一个2个文件，音频很好，但视频不是。第二个视频会导致冻结/闪烁/绿色屏幕。

Video: MPEG4 Video (H264) 1280x720 60fps [V: h264 main L4.1, yuv420p, 1280x720 [default]] Audio: AAC 48000Hz stereo [A: aac, 48000 Hz, stereo [default]]

比较文件，我使它们尽可能相同：

• 的 input.mkv1
  Video: MPEG4 Video (H264) 1280x720 60fps [V: English [eng] (h264 main L4.1, yuv420p, 1280x720) [default]] Audio: AAC 48000Hz stereo [A: English [eng] (aac, 48000 Hz, stereo) [default]]
• 的 input2.mkv

什么可能导致这种行为？

Answer 1

我最终使用此解决方案：https://trac.ffmpeg.org/wiki/Concatenate#protocol

ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

转换成.ts允许我连接而没有奇怪的闪烁。
