  • How to scan a folder recursively in ffmpeg to check for presence of subtitles?

    22 December 2022, by frosty

    I have a folder (with subfolders) of videos on my Raspberry Pi, some containing soft-embedded subtitles and some without.

    


    I want to use ffmpeg to check for the presence of the soft-embedded subtitle, and return a result against each filename so that I can locate.

    


    The videos may be mp4, mkv or avi.

    


    I have been using this command successfully but in a limited way as it only works for .mp4 files and doesn't check recursively. The output is a nice list with either a 0 or 1 at the beginning of the line, where 1 means that there is no subtitle.

    


    for f in *.mp4; do ffmpeg -i "$f" -c copy -map 0:s:0 -frames:s 1 -f null - -v 0 -hide_banner; echo $? "$f" ; done


    


    I have tried all manner of ways like find and -exec, read, xargs, all to no avail. The below is the closest I've got, but it doesn't deal with whitespaces properly so filenames including spaces are split over two lines and the command seems to run only one word at a time, so it fails and shows 1 for everything.

    


    for f in `find /mnt/SSD/ | grep -E '(.mp4|.mkv|.avi)'`; do ffmpeg -i "$f" -c copy -map 0:s:0 -frames:s 1 -f null - -v 0 -hide_banner; echo $? "$f" ; done


    


    Any ideas what I'm doing wrong?

    avcodec/mips: Improve hevc uni weighted vert mc msa functions

    Pack the data to half word before clipping.
    
Use immediate unsigned saturation for clip to max saving one vector register.

    avcodec/dca_parser: improve frame end search

    Parse core frame size directly when searching for frame end instead of
    
using value extracted from previous frame.
    

    Account for unused bits when calculating sync word distance for 14-bit
    
streams to avoid alias sync detection.
    

    Parse EXSS frame size and skip over EXSS frame to avoid alias sync
    
detection.
