• What are the other alternatives to FFMPEG for encoding and very low latency streaming ? [closed]

  23 septembre 2020, par Hamza Ghizaoui

  So the situation as following : I m receiving images on the fly from a camera, BMP format 4000x3000 pixel, encoding them into h264 or h265, and then streaming the result via HTTP and/or UDP.
The whole process must take no more than 30 ms.

  


  I used FFMPEG with hardware acceleration as a start and it seems to deliver. There is doubt among our team that it is the best solution. and I wanna be absolutely sure that it is before I defend it openly :D

  


  would be glad to hear your takes on this :)

  


  Best regards

  


• avformat/matroskadec : Don't skip too much when unseekable

  avformat/matroskadec : Don't skip too much when unseekable
  The Matroska (and WebM) file format achieves forward-compability by
  
  insisting that demuxers ignore and skip elements they don't know about.
  
  Unfortunately, this complicates the detection of errors as errors
  
  resulting from loosing sync can't be reliably distinguished from
  
  unknown elements that are part of a future version of the standard.
  Up until now, the strategy to deal with this situation was to skip all
  
  unknown elements that are not obviously erroneous ; if an error happened,
  
  it was tried to seek to the last known good position to resync from (and
  
  resync to level 1 elements). This is working fine if the input is
  
  seekable, but if it is not, then the skipped data can usually not be
  
  rechecked lateron. This is particularly acute if unknown-length clusters
  
  are in use, as the check for whether a child element exceeds the
  
  containing master element is ineffective in this situation.
  To remedy this, a new heuristic has been introduced : If an unknown
  
  element is encountered in non-seekable mode, an error is presumed to
  
  have happened based upon a combination of the length of the row of the
  
  already encountered unknown elements and of how far away skipping this
  
  element would take us.

• Is there a way to load balance when streaming m3u8 with ffmpeg ?

  12 novembre 2022, par k. kh

  It's not like you're in a problematic situation. It's just my curiosity.

  


  While streaming m3u8 files over http, a lot of people will see the video and I'm worried about the traffic load.
However, even if I search for this, I can't find any necessary knowledge or posts.
Can anyone please give me a brief overview of how I should search, what background knowledge I need, and which open sources are popular ? thank you
