Logitech C920からH.26​​4をストリーミングするFFServer

ffmpegLogitech C920 WebカメラでH.264エンコーディングを有効または実行中にWebキャストに問題がありますffserver。

これは私が使用する設定ファイルですffserver。

# Port on which the server is listening. You must select a different
# port from your standard HTTP web server if it is running on the same
# computer.
Port 8090

# Address on which the server is bound. Only useful if you have
# several network interfaces.
BindAddress 0.0.0.0

# Number of simultaneous HTTP connections that can be handled. It has
# to be defined *before* the MaxClients parameter, since it defines the
# MaxClients maximum limit.
MaxHTTPConnections 2000

# Number of simultaneous requests that can be handled. Since FFServer
# is very fast, it is more likely that you will want to leave this high
# and use MaxBandwidth, below.
MaxClients 1000

# This the maximum amount of kbit/sec that you are prepared to
# consume when streaming to clients.
MaxBandwidth 1000

# Access log file (uses standard Apache log file format)
# '-' is the standard output.

# Definition of the live feeds. Each live feed contains one video
# and/or audio sequence coming from an ffmpeg encoder or another
# ffserver. This sequence may be encoded simultaneously with several
# codecs at several resolutions.

<Feed feed.ffm>

# You must use 'ffmpeg' to send a live feed to ffserver. In this
# example, you can type:
#

File /tmp/feed.ffm
FileMaxSize 100M

# You could specify
# ReadOnlyFile /saved/specialvideo.ffm
# This marks the file as readonly and it will not be deleted or updated.

# Only allow connections from localhost to the feed.
ACL allow 127.0.0.1

# Now you can define each stream which will be generated from the
