This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)
HTML5 audio and video support

13 avril 2011, par kent1

MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.

FFmpeg retrieve a specific program from TS file

8 mai 2017, par chang jc

I tried to retrieve a specific program from a TS file.
Said :

Then I tried to retrieve a specific program as :

ffmpeg -i INPUT -map 0:p:1344 OUTPUT

It succeeds greatly but the only thing I noticed is :

it seems to apply transcode (decode & encode again) to the output implicitely ?

hevcdec : export cropping information instead of handling it internally

This commit is a noop.

This changes the cropping behavior, when it's supposedly only meant to move
it outside of the decoder.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2017-May/211239.html for the
discussion about it.

VLC - Could someone assist me into improving latency in streaming to web based app ?

19 janvier 2017, par zyeek

I have been looking for solutions in which I can stream an IP camera’s stream to HTML 5. Currently as is it doesn’t support RTSP so easily.

I am trying to be able to view the camera’s stream as live as possible. I was hoping someone could help me achieve that. I have been playing with it to get something workable, but at the moment I get a 5s delay stream. It is smooth, but wish to get it hopefully within <1-2s delay if possible.

My current setup goes from taking my IP camera’s stream in RTSP and converting it to a webm and streaming it to a url, which then I plan on using that to put else where in a web app.

What I would like to achieve

Use a protocol that has low latency with audio was well. Webm was used as test, but I can’t seem to get other commands to get the proper stream to be going.

I would like to use DASH, but from reading FFMPEG currently doesn’t support it. I was thinking maybe RTMP would be good enough for now, being both low latency and HTTP 5 compatible. I am just unable to figure out how to get FFMPEG to transcode the RTSP to RTMP.

SETUP :

I am using ffserver and ffmpeg. Overall scope : trying to pull IP camera stream and put it on a web app.

Framework I am use is Meteor JS. So, I am trying to few plugins or outside complex setups as I want to be able to deploy this Meteor app on mobile devices as well. So, I want to stay within the boundaries of what HTML 5 can support.

My current ffserver setup is ffserver.conf (this was taking from bunch of different place :

HTTPPort 8090                      # Port to bind the server to

HTTPBindAddress 0.0.0.0

MaxHTTPConnections 2000

MaxClients 1000

MaxBandwidth 10000             # Maximum bandwidth per client

                               # set this high enough to exceed stream bitrate

CustomLog -

Now I give life to the feed with ffmpeg. Command I use :

ffmpeg -vsync 2 -i rtsp://admin:password@192.168.2.165:88/videoMain -map 0 http://localhost:8090/feed.ffm

which gives the result :
