• Pull a remote stream from server and then restream

  16 août 2018, par F.A

  I my working on Nginx RTMP server to restream iptv. I have two type of urls

  1- http://expamle.com:46801/live/3ni/ab/11939.ts

  2-
  http://example.com:8088/live/tv_10/playlist.m3u8?id=209&sionid=45&pk=54fb381ea

  Both URL’s work in VLC media player.

  Now problem is that ffmpeg exec only URL with .ts extension. but
  not exec url without extension at end.

  How to pull stream from a remote server for that URL which not have .ts extension ?

    exec_static ffmpeg -i http://example.com:80/live/sports_11/playlist.m3u8?id=209&sionid=45&pk=54fb31ea -c:v libx264 -preset veryfast -maxrate 1000k -bufsize 2000k -g 60 -b:a 128k -f flv rtmp://127.0.0.1;

• How do I save file to current location during FOR recursion

  30 septembre 2019, par Blaine P.

  I have a batch script to run ffmpeg on files recursively. Currently the script saves all the new files to a newly created directory named Output. Instead, I would like to save the new files in the same location as the original files. I thought I would use an environmental variable showing the current directory being traversed to during recursion but I can’t find it.

  SET /P i=Enter the file extension
  
  md output
  
  For /R %%a IN (*.%i%) DO ffmpeg -i "%%a" -c:v libx264 -crf 10 -pix_fmt yuv420p "output/%%~na.mp4"

  The script works fine saving the file as the same filename with a new extension but places the file in the new "output" folder. I tried setting a new variable with %cd% within the FOR loop but that didn’t work.

• Video playing, how to play a video back a a rapid rate at random timestamp locations

  10 avril 2020, par Zarc Rowden

  Note : this is a mildly general question that is looking more for pointers in the right direction and not exactly requiring a concise coded answer. I appreciate any and all input, thank you for lending your brain power to me for this moment :)

  



  I have a script that receives midi messages in real time and triggers playback of a single video on various timestamps that are changed/selected regularly and randomly by a user. Currently this is working in the browser, however, I've realized that there is some noticeable latency between (i'm guessing the cause here so please correct me) the moment a request to play a video at a specific time is made(note : the video is not being requested over the wire, this action does not take place until a JS Blob Url is loaded into the player) and the moment where that request is fulfilled and delivered from storage to pixels on the screen.

  



  My question is : Is it reasonable to assume that there is a tool out there, that given the correct video format and optimizations both in the code and in the file that could load an entire, say : 1 gb video into memory and play it back at random timestamps every 60 milliseconds at completely random, constantly changing timestamps.

  



  If you're now all the way down here... Thanks for reading this far, or scanning ! Please let me know if this question makes any sense / could be improved, I'm happy to clarify further.
