• Live TV Stream to Android

  8 mai 2016, par Hd Dream

  I am new user on stackoverflow.
  I wrote you today to get answer and solution to my problem.
  I have input stream come from vlc. I need that all android connected to my network can watch stream in live in the same time like an online channel tv.
  I saw for this channel

  Code : Select all
  www.canal2international.net/live.php

  there is a same ts file is generated for each 45 second.

  I need to do the same but with a mp4 file that I insered on html5 video tag.
  for that I tried to convert my input stream with this cmd on ffmpeg

  Code : Select all
  ffmpeg -i 192.168.1.10:8620 -c:v libx264 -profile:v baseline -c:a aac -ar 44100 -ac 2 -b:a 128k -f segment -segment_time 45 -segment_format_options movflags=+faststart -segment_list D :\live\play.m3u8 -segment_list_size 2 D :\live\watch%03d.mp4

  I’m not satisfied. I can’t insert m3u8 file in html5 video tag because android don’t read it and his content.

  I tried another code that I can say little similar that the result of this page

  Code : Select all
  www.canal2international.net/live.php

  Code : Select all
  ffmpeg -i 192.168.1.10:8620 -hls_flags single_file D :\live\play.m3u8

  It generated two files, a ts and a m3u8.
  I know that html5 video tag can read ts file. Maybe there is a solution somewhere.

  The second way I don’t like in this code is ts file don’t read in real time. When I read file it begin from the first encoding.

  All android connected to my network must watch in real time !

  I don’t know how to solve my problem that’s why I write in thie forum.

  Thank you in advance for all your help !

• How can I make smooth zooming video from image sequence in FFMPEG ?

  26 octobre 2020, par CALKing

  I need to make a video from an image sequence, actually a deepdream image sequence I have generated. And I've generated the images so that every image is a 1.05 x zoom on the last image, hoping to be able to make something like this : https://www.youtube.com/watch?v=dbQh1I_uvjo. But because of the demanding CPU deepdreaming requires, I didn't have the time and resources to generate images for a 30 fps video, but more like a 1 fps video. Which I actually managed to do, my code for that looks like this :

  


  ffmpeg -r 1 -i %04d.jpg -c:v libx264 -r 10 output.mp4


  


  Now to make the video smoother I want to smoothly zoom in 1.05 x on every image in the sequence for about a second or two before continuing to the next image, which should then be in position with the one before. I have no experiene at all with FFMPEG and can't find much help on the internet. Could anyone help me with this ?

  


  Thanks !

  when first video done 2nd column video must start and first video must show just last frame, other left 2 videos still show first frame and wait queue

  


  for example lets say we have these durations :

  


  1.mp4 - 1:00
2.mp4 - 1:35
3.mp4 - 1:20
4.mp4 - 1:05


  


  Also I can prepare screenshots of each video for preview frames (first/last)

  


  Cant even imagine how to do this job with ffmpeg or maybe exists any simplier way for shell ?
