Why calling libav* library doesn't have same quality as ffmpeg command line ?
10 mai 2016, par seaguestI 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 noisesHere is the probe information for the mv.webm :
$ ffprobe mv.webm

handler_name : SoundHandlerChecking 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 ? -
FFMPEG sepia filter

Here’s the command I’m trying.
ffmpeg -i video.mp4 -filter_complex \

FFMPEG sepia filter
28 juin 2018, par Alex KonetchyCan’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.mp4And the output I receive.
