  • Failed encoding Carrierwave-video FFMPEG

    12 septembre 2018, par Cole Phiper

    I’m using Carrierwave-video and Carrierwave-ffmpegthumbnailer. The problem I am having, is the transcoder is now refusing to work & I can’t locate the origin of the error. I tried removing some of the custom settings, but nothing seems to work. How can I fix the transcoder to allow video uploads ?

    story_video_uploader.rb

    require 'mime/types'

    If the command not add subtitle :

    



    ffmpeg -i input0.mkv \
-map 0:v:0 -c:v libx264 -strict -2 -s 426x240   -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename video/videoTrack240p_%d.ts      video/videoTrack240p.m3u8 \

    The streaming is work without error.
I cannot find FFmpeg streaming with subtitle example on long time.
