• FFMPEG to remote server : Live streaming with segments [migrated]

  10 août 2013, par Brianjs

  I have looked around and have found many good articles on how to use ffmpeg to segment live video for HLS streaming. However, I need to be able to use use an encoder from a remote location (that is receiving live video), and then somehow send these segmented files and the m3u8/ts files to a web server in a different location, in real time.

  So :
  REMOTE COMPUTER(camera->ffmpeg->segmenter) -> WEBSERVER(receives files -> users connect for "live" stream)

  My question is : Has anyone seen something similar to this ? Or is there a setting on ffmpeg/ffserver that will let me do this ?

• Set background colour when converting flv to mp4 with ffmpeg

  28 août 2012, par Castles

  I'm attempting to convert flv files (with an alpha channel) that are uploaded to a server to html5 compatible formats. I've got the conversion working but the transparency is rendered as black. What I would like to do is have the ability to specify a colour.

  Is it possible to convert the video and specify the colour ?

  Alternatively, am I able to overlay the video with transparency on a still image that I generate ?

  Update
  I may of solved my own question... Here is my ffmpeg command :

  `ffmpeg -loop_input -f image2 -i background.png -r 25 -t 10 -an -level 21 -refs 2 -b 345k -bt 345k -acodec libfaac -vcodec libx264 -ac 2 -ab 96k -ar 44100 -vf "movie=input.flv, scale=370:500 [logo]; [in][logo] overlay=0:0 [out]" -y -threads 0 output.mp4`

  Which works.. I just need to generate a background image at the right dimensions on the server before converting.

• ffmpeg streaming multiple avi files as created

  2 janvier 2013, par aboredprogrammer

  Backstory :
  I have a VB.net program (that is using a much older COM object accessing a DVR) to create sequentially numbered AVI files each 15 seconds in length. A new AVI is created every 15 seconds with the most recent 15 seconds of video in it. I know the exact datetime that correlates to each file. So files may be named (20121008-133445.avi, so yyyyMMdd-hhmmss.avi).

  Question : Using ffmpeg/ffserver (preferably but I'm open), how can I create a stream such that when a person accesses it that they are presented a continuous video that starts at a position that is as recent as possible and continues to stream the avi files as they are created ?

  I don't have a problem shipping these files off to a Linux box via a samba share (or have the linux box access a share on the windows box) if Linux is more capable. I am however stuck with Windows for the actual generation of the original AVI files.

  The ultimate goal is to be able to view these streams on an iPad, but that process seems pretty well documented elsewhere.

  I found a question that reads similar to my needs but didn't seem to go anywhere : FFmpeg make mpeg2 ts without discontinuity

  Thanks in advance !
