  • FFMPEG doesn't work with mp4 and stdout

    22 août 2014, par Max Grigoriev

    I need to add text to mp4 video. If I write result to file then everything is OK, but I want to read data from ffmpeg stream.

    I run command :

    ffmpeg -i sample.mp4 -filter_complex "drawtext='text=\"Sample Text\"':x=(w-text_w)/2:y=(h-text_h-line_h)/2:fontsize=40:fontcolor=white:fontfile=TimesNewRoman.ttf:enable='between(t,1,5)'"  -f mp4 -

    I received the following error :

    It seems the problem is related to mp4 and "muxer does not support non seekable output"

  • FFMPEG - Convert MKV to MP4 with all streams (subtitles) and watermark

    13 mars 2024, par ShinJii

    I spent few hours researching and still have problem...
I want to convert .mkv file to .mp4 with watermark and subtitles (from mkv).

    



    I tried few commands but always error or success with watermark without subtitles.
Here are some commands I tried (not all) :

    



    Partial Success - some files are converted with subtitles, but I have 153 files that are converted without subtitles... (both from .mkv to .mp4) :
