I'm looking for a scriptable utility to convert a bunch of BMPs and a WAV file into a video. XviD needs to be the output format. I'd like it to work on Linux (Ubuntu) if possible. A command line utility would be great, as I have 36 videos to create this way. A bash
(or [insert favorite scripting language here]) script would be great for this. (I also need to play around with different video dimensions, but I can use other programs to resize.)
I've played around with VirtualDub (for Windows XP), but it doesn't seem to meet these needs. I could be wrong, though. Any pointers to examples would be great.
I'm also playing with ffmpeg
. It seems to fit the bill perfectly, but I can't seem to get it to pull together the BMPs into a video. Here's what I'm trying:
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
And here's what it's saying back:

[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
I've seen a mailing list post about this, but what is suggested doesn't seem to work here.
UPDATE
Here's the updated script with multiple steps:
#!/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.
