  • Is it possible to determine if a subtitle track is imaged based or text based with ffprobe

    21 février 2021, par Shex

    I'm writing a script that burns subtitles into video files to prepare them for a personal stream I'm hosting. I'm having a hard time finding which type of subtitle is used in the file. I use ffprobe to get the files' information, and I can get stuff like the codec type, but I was wondering if there is a way to determine if a subtitle track is image based or text based. I can only think of getting a list of all possible codecs and match the codec type with this list but it would be very useful to have an info somewhere that can tell me "OK this is an image-based subtitle track", as when I burn I cannot use the same filters with ffmpeg to burn image vs. text subtitles.

  • FFMPEG Windows Batch - Recursive Convert based and settings based on Frame Height

    3 avril 2017, par Vahid Jamali

    So I’m trying to make a batch file to use FFMPEG to convert around 1000 MP4 video files.

    I want to recursively go through these folders, possibly use ffprobe to discover the frame height, and then based on the frame height options (360, 480, 720, or 1080 frame height) give them individually different ffmpeg commands.

    I’ve been reading up on various approaches to this just as far as batch processing goes.

    So far I’m at this stage :

    for %%a in ("*.*") do C:\ffinstall\local64\bin-video\ffmpeg -i "%%a"  -c:v libx264 -crf 18 -preset veryslow -tune film -refs 8 -bf 6 -aq-mode 2 -filter_complex "[0:v][1:v]overlay=30:main_h-overlay_h-30,subtitles='D:\add.ass'" -c:a copy "encoded\%%~na.mp4"

    pause

    Code to discover the frame height :

    ffprobe -v error -show_entries stream=height -of default=noprint_wrappers=1 inputfile.mp4

    Trying to figure out conditionals and how their syntax is. Also I’m getting a Unable to parse option value "add.ass" as image size error. Which I believe is due to not being to see the subtitle file.

    Any suggestions on where I can start ? Thanks for any help.
