  • avfilter's anull says "Rematrix is needed between stereo and 0 channels but there is not enough information to do it"

    24 mai 2017, par kuanyui

    I’m trying to write a transcoder according to FFMpeg’s official example with ffmpeg 3.2.4 (official prebuild Win32), and try to transcode a video with stereo audio stream source (from avformat’s dshow).

    In the example code, which passes anull into avfilter_graph_parse_ptr() for audio stream, and "time_base=1/44100:sample_rate=44100:sample_fmt=s16:channels=2:channel_layout=0x3" is passed into avfilter_graph_create_filter(), occurs error in the following avfilter_graph_config() :

    [auto-inserted scaler 0 @ 32f77600] w:iw h:ih flags:'bilinear' interl:0
    
[Parsed_null_0 @ 2e9d79a0] auto-inserting filter 'auto-inserted scaler 0' between the filter 'in' and the filter 'Parsed_null_0'

[auto-inserted resampler 0 @ 330e8dc0] Failed to configure output pad on auto-inserted resampler 0

    I’ve googled for days but didn’t find any clue for it. Doesn’t what anull do is only "Pass the audio source unchanged to the output", why libav want to resample stereo to 0 channel ? What’s going wrong ?

  • Showing FFMPEG not installed even thou its installed discord v12 [closed]

    14 septembre 2021, par Dawn of Justize

    I have been using my discord bot for almost a year now but when today I executed the command npm install, after that it's showing the error ffmpeg not installed and to install it. But ffmpeg is already installed I tried, npm install ffmpeg, npm install ffmpeg static and binaries also. Still, it is showing the same error again and again.It's driving me crazy
