ffmpeg xstack 过滤器布局限制
ffmpeg xstack filter layout limitations
我正在尝试使用各种布局合并多个视频。我发现了一个问题，即布局太大会导致输出失败。即使启用调试日志，我也看不到明确的错误是什么。我假设在将输入分散得足够远时，我达到了分辨率 and/or 大小限制。是否有一些文档概述了 xstack 布局的限制或一些其他文档阐明了我遇到的不同的固有 ffmpeg 限制？使用完全相同的输入但使用较小的布局会成功。
FWIW 我正在使用 ffmpeg-python 包装器库。
这是我在这些失败期间看到的详细输出：

仅供参考，您的过滤器工作 error-free 使用测试源：
from ffmpegio import ffmpeg
ffmpeg(["-y",

使用输出文件配置：
Output #0, image2, to 'sandbox/OutputFile.png':

所以，我怀疑您的输入文件有问题，特别是重复出现的消息：
cur_dts is invalid st:0 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
指向罪魁祸首IMO。您可以尝试在 xstack 之后（或两个输入之前）添加 setpts=N/TB 以查看是否可以解决问题。
我正在尝试使用各种布局合并多个视频。我发现了一个问题，即布局太大会导致输出失败。即使启用调试日志，我也看不到明确的错误是什么。我假设在将输入分散得足够远时，我达到了分辨率 and/or 大小限制。是否有一些文档概述了 xstack 布局的限制或一些其他文档阐明了我遇到的不同的固有 ffmpeg 限制？使用完全相同的输入但使用较小的布局会成功。
FWIW 我正在使用 ffmpeg-python 包装器库。
这是我在这些失败期间看到的详细输出：

使用输出文件配置：
Output #0, image2, to 'sandbox/OutputFile.png':
Metadata:
encoder : Lavf59.16.100
Stream #0:0: Video: png, rgb24(pc, gbr/unknown/unknown, progressive), 3850x2638 [SAR 1:1 DAR 1925:1319], q=2-31, 200 kb/s, 25 fps, 25 tbn

所以，我怀疑您的输入文件有问题，特别是重复出现的消息：
cur_dts is invalid st:0 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
指向罪魁祸首IMO。您可以尝试在 xstack 之后（或两个输入之前）添加 setpts=N/TB 以查看是否可以解决问题。
