ffmpeg concat不使用框架连接到手动框架
我有数百个带有音频（AAC）的简短（10-120秒）视频（H264 MP4）。 （让我们称这些“剪辑”）。 CRF，像素格式，样本率等
速率，
所有相同的视频和音频编解码器，分辨率，帧 带有音频的单个NICE H264 MP4完美同步（如预期）。
cmd_args = ['ffmpeg',
'-f concat',
'-safe 0',
f'-i "{output_filelist_path}"',
'-c copy',
'-y',
'-r 30', # trying this out of desperation
f'"{output_concat_demux}"'
]
cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)
frame_by_frame：
但是，如果我手动迭代每个剪辑视频的每个帧并使用skvideo.io将帧写入mp4，则此视频与Concat_demux版本不同步。
input_dict = { '-r':str(fps) }
output_dict = { '-r':str(fps), '-pix_fmt':'yuv420p', '-vcodec':'libx264', '-crf':'18' }
video_writer = skvideo.io.FFmpegWriter(output_path, inputdict=input_dict, outputdict=output_dict)
for video_path in video_paths:
video = skvideo.io.vread(video_path) # read all frames into np.array
for frame in video:
video_writer.writeFrame(frame)
video_writer.close()
当我在视频编辑器中比较这两个文件（例如，后效效福）并逐帧逐步逐步浏览时，我可以看到，使用每个新剪辑，frame_by_frame版本slips ffmpeg concat_demux slips 1或2 frame trage 版本。到底是怎么回事？我该如何修复 - 或至少要调试 - ？
附带说明，我确实需要逐帧手动连接，因为我还做了很多其他事情（触发剪辑更改上的事件，叠加其他元素等）。而且我需要能够同步串联音频。我希望通过框架手动将视频连接在一起，然后进行后处理，然后使用FFMPEG Concat_Demux版本中的音频进行MUX。但是可惜它们从同步中脱落。
（我发现了很多关于问题的问题是在与音频不同步的视频中使用FFMPEG Concat的地方。但是，这不是我的问题。我使用FFMPEG Concat创建的视频与该视频完全同步音频，但它与手动逐帧串联视频不同步。）
更新-Concat_protocol
我尝试使用Concat协议。现在，输出给出了一个文件，其中视频框架同步到frame_by_frame版本，但是音频已同步到concat_demux版本的音频。因此，它的音频与视频不同步。
intermediate_paths = []
for p in clip_file_list:
intermediate_path = os.path.join(args.output_dir, 'intermediate', os.path.basename(p) + '.ts')
intermediate_paths.append(intermediate_path)
cmd_args = ['ffmpeg',
f'-i "{p}"',
'-c copy -bsf:v h264_mp4toannexb -f mpegts -y',
f'"{intermediate_path}"'
]
cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)
intermediate_paths = '|'.join(intermediate_paths)
cmd_args = ['ffmpeg',
f'-i "concat:{intermediate_paths}"',
'-c copy -bsf:a aac_adtstoasc',
f'"{output_concat_path}"'
]
cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)
我遇到了很多错误，如下所示，
corrupt input packet in stream 0
[mp4 @ 0x137e043d0] Non-monotonous DTS in output stream 0:1; previous: 83027966, current: 83027198; changing to 83027967. This may result in incorrect timestamps in the output file.
这是两个输出文件的信息。输入＃0是ffmpeg concat_demux。输入＃1是逐帧的手动框架。注意Concat.mp4的帧率为29.94 fps。我不确定这是否是问题。我不知道如何使此30（在上面的FFMPEG CONCAT命令中参见'-r 30'）。

I have hundreds of short (10-120seconds) videos (H264 mp4) with audio (aac). (let's call these 'clips'). All identical video and audio codecs, resolution, framerate, crf, pixel format, sample rate etc.
concat_demux:
If I concat these with ffmpeg concat (demuxer), I get a single nice H264 mp4 with audio perfectly synced to the video (as expected).
cmd_args = ['ffmpeg',
'-f concat',
'-safe 0',
f'-i "{output_filelist_path}"',
'-c copy',
'-y',
'-r 30', # trying this out of desperation
f'"{output_concat_demux}"'
]
cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)
frame_by_frame:
However, if I manually iterate every frame of every clip video and write the frames to an mp4 using skvideo.io, this video drifts out of sync with the concat_demux version.
input_dict = { '-r':str(fps) }
output_dict = { '-r':str(fps), '-pix_fmt':'yuv420p', '-vcodec':'libx264', '-crf':'18' }
video_writer = skvideo.io.FFmpegWriter(output_path, inputdict=input_dict, outputdict=output_dict)
for video_path in video_paths:
video = skvideo.io.vread(video_path) # read all frames into np.array
for frame in video:
video_writer.writeFrame(frame)
video_writer.close()
When I compare these two files in a video editor (e.g. AfterEffects) and step through frame by frame, I can see that with every new clip, the frame_by_frame version slips 1 or 2 frames ahead of the ffmpeg concat_demux version. What is going on? How can I fix - or at least debug - this?
On a side note, I do need to concatenate manually frame by frame, as I'm also doing a ton of other stuff (triggering events on clip change, overlaying additional elements etc). And I need to be able to sync a concatenated audio. I was hoping to concatenate the video manually frame by frame and do my post-processing, and then mux with the audio from the ffmpeg concat_demux version. But alas they drift out of sync.
(I've found quite a few posts on SO where the problem is using ffmpeg concat results in videos which are out of sync with the audio. However, this is not my problem. My video created with ffmpeg concat is perfectly in sync with the audio, but it's out of sync with a manually frame-by-frame concatenated video.)
Update - concat_protocol
I've tried using the concat protocol. Now the output of this gives a file where the video is frame synced to the frame_by_frame version, BUT the audio is synced to the audio of the concat_demux version. So its audio is out of sync with the video.
intermediate_paths = []
for p in clip_file_list:
intermediate_path = os.path.join(args.output_dir, 'intermediate', os.path.basename(p) + '.ts')
intermediate_paths.append(intermediate_path)
cmd_args = ['ffmpeg',
f'-i "{p}"',
'-c copy -bsf:v h264_mp4toannexb -f mpegts -y',
f'"{intermediate_path}"'
]
cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)
intermediate_paths = '|'.join(intermediate_paths)
cmd_args = ['ffmpeg',
f'-i "concat:{intermediate_paths}"',
'-c copy -bsf:a aac_adtstoasc',
f'"{output_concat_path}"'
]
cmd = ' '.join(cmd_args)
r = subprocess.call(cmd, shell=True, cwd=args.output_dir)
I am getting loads of errors like below
corrupt input packet in stream 0

here's the info on the two output files. Input #0 is the ffmpeg concat_demux. Input #1 is the manual frame-by-frame. Note the concat.mp4 has a framerate of 29.94 fps. I'm not sure if this is the problem. I couldn't figure out how to make this 30 (see '-r 30' in the ffmpeg concat command above)
