• How to convert from .srt to .ass with FFmpeg without decoding errors

  10 avril 2020, par symonxd

  When I try the following command with FFmpeg (v. git-2020-03-24-e5d25d1) : ffmpeg -i subs.srt subs.ass, I get a bunch of the following errors :

  



  [srt @ 0000028ea78fa780] Invalid UTF-8 in decoded subtitles text; maybe missing -sub_charenc option
Error while decoding stream #0:0: Invalid data found when processing input


  



  and :

  



  [ass @ 0000028ea78ffe40] ReadOrder gap found between 3 and 4


  



  I found that my .srt file contains the following char : ë
I tried adding the flag -sub_charenc UTF-8 as stated here with no success.

  



  How can I successfully convert .srt to .ass ?

  


• ffmpeg stops reading rtsp livestream after some seconds

  26 décembre 2020, par user3019668

  I'm trying to save locally a rtsp livestream with ffmpeg but it stops after a few seconds. It works smooth, but suddently it just stops, more or less always after 10-15 seconds.

  



  This is the command :

  



  ffmpeg -rtsp_transport tcp -i rtsp://xxx.xxx.xxx.xxx:554/test.sdp -c copy test.ts


  



  And this is the log. I tried with previous ffmpeg versions with the same result :
