我正试图在Debian 7.5上用我的Tenvis IP摄像机录制动态3.2.12的视频流。
我使用标准的debian包
sudo apt-get install motion
假设我的DNS IP cam是网络摄像头，用户：admin，密码：password
/etc/motion/motion.conf
Bellow是我的配置文件设置：
netcam_url http://webcam/videostream.cgi
netcam_userpass admin:password
target_dir /tmpµ/motion
# The mini-http server listens to this port for requests (default: 0 = disabled)
webcam_port 8081
ffmpeg_cap_new on
ffmpeg_video_codec mpeg4
output_motion on
snapshot_interval 0
# Quality of the jpeg (in percent) images produced (default: 50)
webcam_quality 50
# Output frames at 1 fps when no motion is detected and increase to the
# rate given by webcam_maxrate when motion is detected (default: off)
webcam_motion off
# Maximum framerate for webcam streams (default: 1)
webcam_maxrate 15
# Restrict webcam connections to localhost only (default: on)
webcam_localhost on
# Limits the number of images per connection (default: 0 = unlimited)
# Number can be defined by multiplying actual webcam rate by desired number of seconds
# Actual webcam rate is the smallest of the numbers framerate and webcam_maxrate
webcam_limit 0
control_port 8080
control_authentication admin:password
问题＃1
在地址使用图腾视频播放器时
http://localhost:8081
程序开始在工作目录中写入图像，我可以显示“电影”

视频播放器似乎一次只加载一个图像，延迟时间为3秒，进度条运行。

avcodec_open - 无法打开编解码器：操作正在进行中。
我为ffmpeg_video_codec尝试了其他编解码器。Flv，swf引发同样的错误。
任何的想法 ？
