• How to http streaming while encoding the accessed file

  5 décembre 2020, par hibiki31

  I am making a web application that plays videos.

  


  Files include non-mp4 in my server.
So I need to convert it, but I want to do it when it is accessed.
I can't change the original or use additional storage space.

  


  I'm learning Python, but I'm happy with any solution.

  


  This function is implemented by Plex Home media server.
https://www.plex.tv/

  


  Thank you.

  Thanks for the comments i found.

  I haven't tried the code yet.

  


  I'm worried about three options.

  


  First, implemented in Python code.
Second, implemented as a module for applications like Nginx.
Third, Google already knows the answer.

  [mpegts @ 000002922adc28c0] Packet corrupt (stream = 0, dts = 31658400).
D :\xxxxxx\xxxxxxxx\xxxxxxxx\xxxxxxxxxxxx.ts : corrupt input packet in stream 0

  


  i got this errors. when i up to tile=10x1250 instead of 11x1300 or 12x1350 etc.

  


  my default and didnt get any errors of settings :
ffmpeg -i "D :\xxxxxx.ts" -frames 1 -vf "select=not(mod(n,18)),scale=200:100,tile=10x1250" "D :\xxxxxx.png"

  


  im very noob and i need full worker of codes without learning

  


• Are there people interested in converting ffmpeg source to Go ?

  30 septembre 2018, par No One

  After seeing that Go compiler have been converted from C to Go I thought same for ffmpeg ? Don’t want to go deep into reasons as I think they are obvious. It was very hard to be so close to the have rich library as ffmpeg in other language. It was even hard to make bindings for that scale of library. I’m not enough advanced to start something like this myself, so is there anybody else interested in this ? If yes then where this question worth to be addressed, so people interested in this may have discussion ?

  (Seems not enough obvious so adding some details.)

  For applications which use large amount of commands with different complexity it is hard to read the code as it’s not actually a code. Instead, it’s commands which you will need to understand by reading docs from ffmpeg’s docs page. I had used ffmpeg before in Nodejs and there was lots of logic of manipulating command string. Also sometimes in windows it was ending with cmd limitations error. When you are working with some language it is nice to see whole logic in that language. So you know go ? than you know everything that is happening with this code without even going off from code and reading docs of another application.

  There may be some benefits from executing stuff in goroutines so you can handle concurrency in the way you want not in the way it is implemented in ffmpeg.

  Build faster with Go.

  Less code.

  Possibility to split code into smaller packages.

  Also if you are familiar why community converted compiler from C to Go than I think some reasons will fit too.
