"Трансляция видео. Поделитесь опытом"

Отправлено Demetrio , 16-Янв-04 15:55 
Захотелось странного. Вещания внутри сетки.
Почитал, собрал из портов ffmpeg4. Хорошо.
Почитал, настроил конфиг, чтобы из готового mpg-файла читал и вперед.
Сразу напоролся на 2 проблемы.
1. Вещаниние не on-line.
2. Жутко тормозит клиент( WMP9 ). Я и буфер на 15 сек. установил, но все равно как-то странно подсасывает, с какими-то немелкими паузами. Дело в сервере, так как, скажем rbc-tv, сосет без проблем.

Пришлите мне готовый ffserver.conf.
Заранее спасибо
Дмитрий

Вывеси пример своего конф. файла и все тебе подскажут что не так, ведь необходимо знать, что ты собираегся вещать, через какую сетку(10 или 100) с каким качеством и т. д. без етого  кто тебе подскажет. А какая версия ffmpeg4, я пробывал с слегка подправленим дефолтовски конфигом все работает на ура !!  А клиент скорее всего тормозит и-зза неправильной настройки сервера !!

У меня тв-тюнер Aver TV-capture
Debian 3.0r2
сетка 100 Мбит
есть желание наладить трансляцию по сети, у кого работает -  поделитесь опытом, какой софт используете, как настраивать, где почитать об этом. Заранее благодарен.

да, я тоже очень хочу это узнать!

а какая модель Aver TV-Capture? и как ты ее установил на Debian?

спасибо.

чего подправлять?

# 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 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 100

# This the maximum amount of kbit/sec that you are prepared to
# consume when streaming to clients
MaxBandwidth 2000

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

# Suppress that if you want to launch ffserver as a daemon

# 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 feed1.ffm>

# You must use 'ffmpeg' to send a live feed to ffserver. In this
# example, you can type:
#
# ffmpeg http://localhost:8090/feed1.ffm

# ffserver can also do time shifting. It means that it can stream any
# previously recorded live stream. The request should contain:
# "http://xxxx?date=[YYYY-MM-DDT][[HH:]... must specify
# a path where the feed is stored on disk. You also specify the
# maximum size of the feed (100M bytes here). Default:
# File=/tmp/feed_name.ffm FileMaxSize=5M
File /tmp/feed1.ffm
FileMaxSize 3M

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

# Specify launch in order to start ffmpeg automatically
#Launch

# Only allow connections from localhost to the feed
ACL allow 192.168.1.1 192.168.1.253

##################################################################
# Now you can define each stream which will be generated from the
# original audio and video stream. Each format has a filename (here
# 'test1.mpg'). FFServer will send this stream when answering a
# request containing this filename.

#<Stream test1.mpg>

# coming from live feed 'feed1'
#Feed feed1.ffm

# Format of the stream : you can choose among:
# mpeg       : MPEG1 multiplexed video and audio
# mpegvideo  : only MPEG1 video
# mp2        : MPEG2 audio (use AudioCodec to select layer 2 and 3 codec)
# ogg        : Ogg format (Vorbis audio codec)
# rm         : Real Networks compatible stream. Multiplexed audio and video.
# ra         : Real Networks compatible stream. Audio only.
# mpjpeg     : Multipart JPEG (works with Netscape without any plugin)
# jpeg       : Generate a single JPEG image.
# asf        : ASF compatible streaming (Windows Media Player format).
# swf        : Macromedia flash(tm) compatible stream
# avi        : AVI format (open divx video, mpeg audio sound)
# master     : special ffmpeg stream used to duplicate a server
#Format mpeg

# Bitrate for the audio stream. Codecs usually support only a few
# different bitrates.
#AudioBitRate 32

# Number of audio channels : 1 = mono, 2 = stereo
AudioChannels 1

# Sampling frequency for audio. When using low bitrates, you should
# lower this frequency to 22050 or 11025. The supported frequencies
# depend on the selected audio codec.
#AudioSampleRate 44100

# Bitrate for the video stream.
#VideoBitRate 64

# Number of frames per second
#VideoFrameRate 3

# Size of the video frame : WxH (default: 160x128)
# The following abbreviation are defined : sqcif, qcif, cif, 4cif
#VideoSize 160x128

# transmit only intra frames (useful for low bitrates, but kills frame rate)
#VideoIntraOnly

# If non intra only, an intra frame is transmitted every VideoGopSize
# frames Video synchronization can only begin at an I frames.
#VideoGopSize 12

# More MPEG4 parameters
# VideoHighQuality
# Video4MotionVector

# Choose your codecs:
#AudioCodec mp2
#VideoCodec mpeg1video

# Suppress audio
#NoAudio

# Suppress video
#NoVideo

#VideoQMin 3
#VideoQMax 31

# Set this to the number of seconds backwards in time to start. Note that
# most players will buffer 5-10 seconds of video, and also you need to allow
# for a key frame to appear in the data stream.
#PreRoll 15

# ACL:

# You can allow ranges of addresses (or single addresses)
#ACL ALLOW <first address> <last address>

# You can deny ranges of addresses (or single addresses)
#ACL DENY <first address> <last address>

# You can repeat the ACL allow/deny as often as you like. It is on a per
# stream basis. The first match defines the action. If there are no matches,
# then the default is the inverse of the last ACL statement.
#
# Thus 'ACL allow localhost' only allows access from localhost.
# 'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
# allow everybody else.

##################################################################
# A stream coming from a file : you only need to set the input
# filename and optionnally a new format. Supported conversions:
#    avi -> asf

#<Stream feed2.ffm>
#File "/home/demetr/video/2.ffm"
#NoAudio
#</Stream>

<Stream test.asf>
File "/home/demetr/video/1.asf"
#Feed feed1.ffm

# RTSP examples
#
# You can access to this stream with the RTSP URL:
#   rtsp://localhost:5454/test1-rtsp.mpg
#
# A non standard RTSP redirector is also created. Its URL is:
#   http://localhost:8090/test1-rtsp.rtsp

#<Stream test1-rtsp.mpg>
#Format rtp
#File "/usr/local/httpd/htdocs/test1.mpg"
#</Stream>


##################################################################
# SDP/multicast examples
#
# If you want to send your stream in multicast, you must set the
# multicast address with MulticastAddress. The port and the TTL can
# also be set.
#
# An SDP file is automatically generated by ffserver by adding the
# 'sdp' extension to the stream name (here
# http://localhost:8090/test1-sdp.sdp). You should usually give this
# file to your player to play the stream.
#
# The 'NoLoop' option can be used to avoid looping when the stream is
# terminated.

#<Stream test1-sdp.mpg>
#Format rtp
#File "/usr/local/httpd/htdocs/test1.mpg"
#MulticastAddress 224.124.0.1
#MulticastPort 5000
#MulticastTTL 16
#NoLoop
