Convert videos to KidiZoom® avi video files

# IMPORTANT Please adjust input and output filenames below
export input_filename="your_input_video_filename_with_extension"
export output_filename="100_0042.AVI"

# IMPORTANT you may need to adjust -q:v for having around 1.3Mbits/s)
export video="-vcodec mjpeg -vf scale=320:240 -r 15 -pix_fmt yuvj422p -q:v 4"
export audio="-acodec pcm_s16le -ar 22050 -ac 1"
export extra="-map_metadata -1 -fflags +bitexact -metadata ISRC=Generplus -metadata artist=Generplus -metadata copyright=Generplus -metadata date=2010-06-29 -y"
ffmpeg -i ${input_filename} ${video} ${audio} ${extra} ${output_filename}

Convert audios to KidiZoom® wav audio files

# IMPORTANT Please adjust input and output filenames below
export input_filename="your_input_audio_filename_with_extension"
export output_filename="V0042.WAV"

# mono, 22050Hz, pcm signed 16bit little endian, no metadata
export filename="your_input_audio_filename_with_extension"
export audio="-acodec pcm_s16le -ar 22050 -ac 1"
export extra="-map_metadata -1 -fflags +bitexact -y"
ffmpeg -i ${input_filename} ${audio} ${extra} ${output_filename}

Extra: Use ffmpeg for creating the animated gif

The animated gif example has been created with the following commands:

wget https://upload.wikimedia.org/wikipedia/commons/transcoded/c/c0/Big_Buck_Bunny_4K.webm/Big_Buck_Bunny_4K.webm.480p.webm

# IMPORTANT Please adjust input and output filenames below
export background_image_filename="images/kidizoom_back.png"
export input_filename="Big_Buck_Bunny_4K.webm.480p.webm"
export output_filename="images/kidizoom_back_with_video.gif"

# we keep only 20s, seeking first to 318s, resize to 144x112, only 10fps
ffmpeg -ss 318 -t 20 -i ${input_filename} -vf "fps=10,scale=144x112:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 tmp.gif

# we add a background and put the gif video at (216, 144)
ffmpeg -t 20 -loop 1 -i ${background_image_filename} -i tmp.gif -filter_complex "overlay=216:144" -loop 0 ${output_filename}

Note video to gif command inspired from the article How do I convert a video to GIF using ffmpeg, with reasonable quality?.
