• HTTP Livestreaming with ffmpeg

  25 août 2016, par Hugo14453

  Some context : I have an MKV file, I am attempting to stream it to http://localhost:8090/test.flv as an flv file.

  The stream begins and then immediately ends.

  The command I am using is :

  sudo ffmpeg -re -i input.mkv -c:v libx264 -maxrate 1000k -bufsize 2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8090/test.flv

  A breakdown of what I believe these options do incase this post becomes useful for someone else :

  sudo

  Run as root

  ffmpeg

  The stream command thingy

  -re

  Stream in real-time

  -i input.mkv

  Input option and path to input file

  -c:v libx264

  Use codec libx264 for conversion

  -maxrate 1000k -bufsize 2000k

  No idea, some options for conversion, seems to help

  -an -bsf:v h264_mp4toannexb

  Audio options I think, not sure really. Also seems to help

  -g 50

  Still no idea, maybe frame rateframerateframerateframerate ?

  http://localhost:8090/test.flv

  Output using http protocol to localhost on port 8090 as a file called test.flv

  Anyway the actual issue I have is that it begins to stream for about a second and then immediately ends.

  The mpeg command result :

• how to build ffmpeg with burn text on hls output while maintaining the aspect ratio

  26 février 2016, par Aameer

  My objective is to burn a text(watermark) at a particular time range on the outputed hls video, I also have to change just the height and maintain the aspect ratio which I am able to do but the burning in text part is not working. First the ffmpeg I used is for 14.04 ubuntu, details are here. I don’t think this build supports subtitle (docs) filter which I could have used for my purpose as described here. when i enter ffmpeg into the terminal this is the output

  then I tried this

  based on an answer here and got this error

  I tried a static build too which i got from here but still couldn’t make it work. with this static build i tried :

  Any help in this regard would be appreciated. I don’t have much experience with compiling , otherwise would have done with support for libass as mentioned in the documentation here

• Convert video by ffmpeg not working in chrome

  18 novembre 2015, par Ducthien

  I used command :

    $ ffmpeg -y -i "E:\SharingVideo\src\main\webapp\resources\video\input\input.mp4" -an -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:720" "E:\SharingVideo\src\main\webapp\resources\video\input\input_an.mp4"

  to get only video with format h264 (without sound). Cmd result :
