Доброго времени суток!
У кого нибудь получилось заставить motion писать mpeg1 или mpeg4 ?
Использую последний motion из сизифа.
Вот кусок из motion.conf относящийся к ffmpeg:

#Use ffmpeg to encode mpeg movies in realtime (default: off)
ffmpeg_cap_new on

#Use ffmpeg to make movies with only the pixels moving
#object (green ghost images) (default: off)
ffmpeg_cap_motion off

#Use ffmpeg to encode a timelapse movie
#Default value 0 = off - else save frame every Nth second
ffmpeg_timelapse 0

#The file rollover mode of the timelapse video
#Valid values: hourly, daily (default), weekly-sunday, weekly-monday, 
monthly, manual
ffmpeg_timelapse_mode daily

#Bitrate to be used by the ffmpeg encoder (default: 400000)
#This option is ignored if ffmpeg_variable_bitrate is not 0 (disabled)
ffmpeg_bps 500000

#Enables and defines variable bitrate for the ffmpeg encoder.
#ffmpeg_bps is ignored if variable bitrate is enabled.
#Valid values: 0 (default) = fixed bitrate defined by ffmpeg_bps,
#or the range 2 - 31 where 2 means best quality and 31 is worst.
ffmpeg_variable_bitrate 0

#Codec to used by ffmpeg for the video compression.
#Timelapse mpegs are always made in mpeg1 format independent from this 
option.
#Supported formats are: mpeg1 (default), mpeg4, and msmpeg4.
#mpeg1 gives you files with extension .mpg
#mpeg4 or msmpeg4 give you files with extension .avi
#msmpeg4 is recommended for use with Windows Media Player because
#it requires no installation of codec on the Windows client.
ffmpeg_video_codec msmpeg4

Файл avi создается, но его не прочитать :(
Запускаю ffplay -stats /var/tmp/cam0/01-20041004102112.avi
В ответ вот что:
Input #0, avi, from '/var/tmp/cam0/01-20041004102112.avi':
  Duration: 00:00:00.0, bitrate: -2147483 kb/s
  Stream #0.0: Video: msmpeg4v2, 768x576, 2.00 fps
  10.94 A-V:  0.000 aq=    0KB vq=    0KB
какой то не понятный битрейт, да и fps.
Может есть идеи как побороть ?
