• Revision 527fc5caf6 : Fix loopfilter bug In the rare case were 4x4 interior filtering was called for

  9 juillet 2013, par John Koleszar

  Changed Paths :
   Modify /test/test-data.sha1

   Modify /vp9/common/vp9_loopfilter.c

  
  
  Fix loopfilter bug

  In the rare case were 4x4 interior filtering was called for but no
  8x8 or larger filtering takes place, the previous code was skipping
  the filtering. This patch fixes the issue by including the interior
  mask in the overall mask for the filter application loops.

• Converting a rtsp stream to hls but got error "Non-monotonous DTS in output stream 0:0"

  8 mai 2023, par Devi

  I'm converting a rtsp live camera stream to hls using ffmpeg, it is all good the first few hours, each segment file sizes around 1.1M, which match the setting of segment_time of 5 seconds. However, when I check back a few days later, the size of each segment file became 20G, and I found that some error are logged.

  


  My current implementation is like this :

  


  ffmpeg -fflags nobuffer \
           -rtsp_transport tcp \
           -i rtsp://abc.com/live.sdp \
           -fps_mode 0 \
           -copyts \
           -c copy \
           -movflags frag_keyframe+empty_moov \
           -hls_flags delete_segments+append_list \
           -f segment \
           -segment_list_flags live \
           -segment_time 5 \
           -segment_list_size 3 \
           -segment_format mpegts \
           -segment_list /app/mount/test/live.m3u8 \
           -segment_list_type m3u8 \
           -segment_wrap 10 \
           /app/mount/test/%04d.ts \
           2>&1 


  


  Here's the logged error :

  I've tried :

  


  

  1. Changing the option -fps_mode with passthrough, vfr, drop.

  


  2. Changing the option -c with -c copy, -c:a copy -c:v libx264.

  


  


  None of the above works for me.
