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:
[...]

[image2 @ 0x97e5ac0]Could not find codec parameters (Video: bmp)
/home/ben/Pending/1080p_export/6/Sequence %d%d%d%d%d%d.bmp: could not find codec parameters
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。
答案 0 :(得分:2)
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:
为此,我建议使用mpeg1作为中间视频格式。

这就是我最终的结果,仅供其他人参考。
