• FFMPEG sepia filter

  24 avril 2017, par Alex Konetchy

  Can’t seem to figure out why my colorchannelmixer filter is not working with ffmpeg. It doesn’t appear to output any errors, but the ouput.mp4 video is just a 0 second long video with no thumbnail.

  Here’s the command I’m trying.

  ffmpeg -i video.mp4 -filter_complex \
  
  "[0:v] colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131[f1];\
  
  [f1] eq=1.0:0:1.3:2.4:1.0:1.0:1.0:1.0 [outv]" -map "[outv]" output.mp4

  And the output I receive.

• Why calling libav* library doesn't have same quality as ffmpeg command line ?

  10 mai 2016, par seaguest

  I am using the ffmpeg 3 to do the video format conversion, it works fine when I use the command line mode, but when I call the libav* library, I get a audio quality loss problem (there is a lot of noises in the audio).

  Here are the two files :

  mv.webm - original file
  mv2.mp4 converted with libarary , a lot of noises

  Here is the probe information for the mv.webm :

  $ ffprobe mv.webm

  Checking the setting section, crf=23.0 for both (the rest are exactly the same), but the output bitrate are different (the audio for calling code mode has a lot of noises), how is that possible ?

  Why the command line mode and use libav* library mode with same setting, but have different output ?
  What should I do to call libav* library to get lossless video conversion ?

• distorted video during ffmpeg h264 video with audio recording

  16 mars 2018, par Developer

  I am continuously recording a video with audio from an ip camera using ffmpeg. I am getting a distorted video when I get in to the picture. If the background is still, the video looks normal, but as soon as I step in to the picture, I see myself only being distorted while the background stays intact. If anyone went through this issue, I would really appreciate your help. Here is a command that I am using :

  ffmpeg -i rtsp://admin:admin@192.168.1.9/mpeg4 -map 0 -c:v libx264 -c:a aac -pix_fmt yuv420p -f segment -segment_time 60 -segment_wrap 10 -reset_timestamps 1 %d.mp4

  This is a ffmpeg command output :
