Question

我正在寻找一个可编写脚本的实用程序来将一堆BMP和一个WAV文件转换为视频。 XviD需要是输出格式。如果可能的话，我希望它可以在Linux（Ubuntu）上运行。命令行实用程序会很棒，因为我有36个视频可以用这种方式创建。 bash（或[在此插入喜欢的脚本语言]）脚本对此非常有用。（我还需要使用不同的视频尺寸，但我可以使用其他程序来调整大小。）

我玩过VirtualDub（适用于Windows XP），但它似乎无法满足这些需求。不过我可能错了。任何指向示例的指针都会很棒。

我也在玩ffmpeg。它似乎完全符合该法案，但我似乎无法将BMP整合到一个视频中。这是我正在尝试的：

for directory in $BMP_DIRECTORY_PATH/*
do
    ffmpeg \
        -f image2 \
        -i "$directory/Sequence %d%d%d%d%d%d.bmp" \
        -r 29.97 \
        -vcodec mpeg4 \
        -vtag xvid \
        \
        -i "$file/audio.wav" \
        -acodec libmp3lame \
        \
        $(basename $directory.avi)
done

这就是它所说的：

[...]

我已经看到mailing list post有关此问题，但建议的内容似乎不起作用。

更新

这是包含多个步骤的更新脚本：

#!/usr/bin/env bash

# bmp+wav2xvid+mp3
# 
# Although it has a cryptic name, it's pretty descriptive.  This script consumes BMPs (Windows bitmaps) and WAVs (Microsoft AD-PCM Waveforms) to make an XviD (MPEG-4 video) movie.
# 
# By convention, you pass it a directory with one or more directories that contain:
#
#     * Frames named "frame_001.bmp", "frame_002.bmp", etc.
#     * Audio named "audio.wav"
# 
# Author: Benjamin Oakes

# FIXME: The audio doesn't get muxed correctly.  The A/V sync is off a little.  At the beginning it looks pretty okay, but by the end the mouths definitely don't match up with the words that are said.

请查看我最终上班的答案。

Answer 1

我认为你想要立刻做太多事情。尝试将任务分解为三个不连续的操作：

从bmp images创建视频
mux in the audio
编码为目标格式

为此，我建议使用mpeg1作为中间视频格式。

Answer 2

这就是我最终的结果，仅供其他人参考。

用于将BMP + WAV转换为视频（XviD）的Scriptable实用程序？
