  avformat/hls : Be more picky on extensions
  This blocks disallowed extensions from probing
  
  It also requires all available segments to have matching extensions to the format
  
  mpegts is treated independent of the extension
  It is recommended to set the whitelists correctly
  
  instead of depending on extensions, but this should help a bit,
  
  and this is easier to backport
  Fixes : CVE-2023-6602 II. HLS Force TTY Demuxer
  
  Fixes : CVE-2023-6602 IV. HLS XBIN Demuxer DoS Amplification
  The other parts of CVE-2023-6602 have been fixed by prior commits

• Ffmpeg - Reading header information takes too long

  13 mars 2023, par Md Yeamin

  I am using ffmpeg-kit to encode videos on android devices. For some files ffmpeg takes too long to read the header information. This issue happens very randomly. Sometime the execution completes within 1 or 2 seconds, sometime it takes longer than 10 seconds to complete, for the file linked below.

  


  I have build ffmpeg to log some additional info to figure out the root cause. There is a 10s gap between the log output at 15:17:02.276 and 15:17:12.909 (added a separator for quick find). After completion of the mov_read_ftyp there is a long delay before the mov_read_dref method starts the execution. Is there any other method that executed in between and could take this much long time to complete the execution ? What could be the reason behind the delay ?

  


  Here is detailed log about the issue.

• How to ffmpeg command execution in ffmpeg4android app

  3 février 2014, par Sanket990

  If i m using ffmpeg4android Play store app and executing command for video trim but they are not working i m using below command for trimming

  ffmpeg -i /sdcard/vide.mp4 -ss 00:10:00 -t 00:12:00 -async 1 /sdcard/cut.mp4

  Above Command Execute but not showing file cut.mp4 in sdcard .if you know another way for video trimming then show me example or link Thanks in Advance

  If i m running this command showing Logcat

  Looks like Vk log is not increasing in size
  /sdcard/vide.mp4 : No such file or directory
  I m already add file in sdcard path
