• avformat/http: check the auth string contents not the pointer which cannot be NULL

  14 octobre 2013, par Michael Niedermayer

  avformat/http: check the auth string contents not the pointer which cannot be NULL
  It appears this bug originates from a "work in progress" patch from
  
  ffmpeg-devel that was heavily redesigned by and integrated in libav
  And that patch even had a reply and review on the mailing list pointing
  
  out that it had a bug.
  This fixes a deadlock with ffserver
  See : [FFmpeg-devel] [PATCH] Fix HTTP authentication problem for POST actions.
  
       [FFmpeg-devel] [PATCH 1/3] Introduce auth_phase flag, which will be true if authorization needs to be sent, but the type of authorization is not known yet Partial fix #3036
  
       [FFmpeg-devel] [PATCH 2/3] Only add Transfer-Encoding header when not in authorization phase, because server will wait (indefinitely) for data when receiving this header Partial fix #3036
  
       [FFmpeg-devel] [PATCH 3/3] Only allow posting data and/or forcing a 200 code, enabling posting isml chunks, -after- we did a possible first request to get a 403 from the server telling us which type of authentication to apply Final part fix #3036

• Why does my ffmpeg audio sound slower and deeper - sample rate mismatch

  ok so this is a discord bot to record voice chat&#xA;https://hatebin.com/hgjlazacri&#xA;Now the bot works perfectly fine but the issue is that the audio sounds a bit deeper and slower than normal.. Why does it happen ? how can I make the audio sound 1:1..
