这是由于 FFmpeg 在 macOS 上处理字幕文件路径时，因路径中包含单引号导致的参数解析错误。

具体原因是软件生成的 FFmpeg 命令中，字幕滤镜参数 -vf "subtitles='end.ass'" 在 macOS 环境下被错误解析，FFmpeg 无法识别 'end.ass' 这个路径。

解决方案：

  1. 临时解决（针对当前任务）：

    • 进入日志中显示的临时目录：/Users/zhousheng/Documents/python/pyVideoTrans/tmp/25097/d5b7bbfef0/
    • 手动执行修正后的 FFmpeg 命令。将原命令中的 -vf "subtitles='end.ass'" 替换为 -vf "subtitles=end.ass"（去掉路径两边的单引号）。
    • 例如，CPU 编码的命令应修改为：
      ffmpeg -hide_banner -ignore_unknown -threads 0 -y -progress compose1770619445.927959.txt -i novoice.mp4 -i origin_audio.m4a -map 0:v -map 1:a -c:v libx265 -c:a copy -vf "subtitles=end.ass" -movflags +faststart -crf 24 -preset veryfast -t 3884.680000 laste_target.mp4

  2. 根本解决（更新软件）：

    • 这是一个已知的 macOS 平台兼容性问题。请更新你的 pyVideoTrans 到最新版本。如果你是源码部署，请执行 git pull 拉取最新代码，然后重新 uv sync。此问题在较新版本中已修复。

注意：你的系统是 macOS arm64，使用了 hevc_videotoolbox 硬件编码器，这是正确的。但字幕路径解析错误导致编码失败，软件自动回退到 CPU 编码（libx265）也因同样原因失败。

已经是最新代码了，还是报这个错误，怎样解决？

Floor #3 DeepSeek Posted at 13 hours ago

这是由于最新代码中针对 macOS 的 FFmpeg 字幕路径处理逻辑可能仍未完全覆盖你的特定情况。错误核心是 FFmpeg 滤镜参数 subtitles='end.ass' 中的单引号在 macOS 系统上被错误解析。

解决方案：

  1. 手动修改源码（临时方案）：

    • 找到源码文件：/Users/zhousheng/Documents/python/pyVideoTrans/videotrans/translate/translate.py（路径可能类似，请根据你的实际目录查找）。
    • 在文件中搜索 subtitles= 或 "subtitles='"。
    • 找到构建 FFmpeg 命令行的代码段。通常，它会将字幕文件路径用单引号包裹。你需要修改这部分代码，移除路径两边的单引号，或者确保路径是绝对路径且不加引号。
    • 例如，将类似 f"subtitles='{字幕文件路径}'" 的代码修改为 f"subtitles={字幕文件路径}"（注意：如果路径包含空格，则仍需引号，但你的临时路径 end.ass 不含空格，可以去掉）。
    • 保存文件并重启软件。

  2. 使用绝对路径（测试方案）：

    • 在软件的高级设置或相关配置中，检查是否有选项可以指定输出目录或临时目录。尝试将其设置为一个不包含空格、中文和特殊字符的绝对路径（例如 /Users/zhousheng/video_tmp）。
    • 这可能会影响 FFmpeg 命令生成时路径的构建方式。

  3. 反馈给开发者：

    • 由于你已确认是最新代码，此问题可能是一个尚未被广泛报告的边缘案例。
    • 请将完整的错误日志（特别是包含 [DEBUG] cmd= 的那几行命令）提交到 pyVideoTrans 的官方 Issues 页面或论坛，并注明你的 macOS 版本和软件版本（v3.96）。

根本原因分析：在 macOS 的某些 shell 环境下，FFmpeg 通过 Python subprocess 调用时，对滤镜字符串中嵌套引号的处理可能与 Windows/Linux 不同，导致 'end.ass' 没有被正确剥离，FFmpeg 将其视为文件名的一部分而找不到文件。

临时完成当前任务：按照之前的方法，进入临时目录 /Users/zhousheng/Documents/python/pyVideoTrans/tmp/25097/d5b7bbfef0/，手动运行修改后的 FFmpeg 命令（去掉 subtitles= 后的单引号）来生成最终视频。

打开软件目录/videotrans/trans_create.py
搜索 f"subtitles='{subtitles_file}'"
删掉 这里面的两个单引号 '
注意只删除单引号，共有两个地方需要这样修改
