  • Closed Captioned TS to Open Captioned MP4 (w/Accurate Positioning)

    19 décembre 2019, par Cody Greene

    I am attempting to convert closed captioned MPEG TS files to open captioned MP4s using ffmpeg.

    I am having trouble retaining the positioning of the captions.

    The closest I’ve gotten is with this simple script :

    ffmpeg -f lavfi -i movie=input.ts[out+subcc] -map 0:1 output.ass
    
ffmpeg -i input.ts -vf "subtitles=output.ass" -c:v libx264 -pix_fmt yuv420p -b:v 8000k -c:a aac -b:a 192k target.mp4

    The result of this is the open captions are shifted FAR left and the bounding box draws black over the empty spaces left of wherever text is centered (ssa adds "/h", easily removed with sed, but then it’s left-aligned captions only)

    However, the vertical position, overall size, etc. all look great.

    Most subtitle formats force everything to the bottom center, but I’m trying to mimic the look of an open caption on the mp4 output.

    I’ve tried several formats with ccextractor and ffmpeg, but no luck. Any ideas what I’m doing wrong ?

  • [Turmux][ffmpeg] encounter "can't open stat file" when use "-pass"

    15 février 2020, par Jackal Zhao

    I installed ffmpeg in turmux, in my home directory, ran :

    ffmpeg -y -i /sdcard/FFMPEG/in.mp4 -c:v libx264 -b:v 2600k -pass 2 -c:a copy /sdcard/FFMPEG/out3.mp4

    the error bumps :

    ratecontrol_init: can't open stats file

    if I enter /sdcard/FFMEPG folder first, then run
    ffmpeg -y -i /sdcard/FFMPEG/in.mp4 -c:v libx264 -b:v 2600k -pass 2 -c:a copy /sdcard/FFMPEG/out3.mp4
    the task will run successfully.

    then I went back to turmux home directory, ran
    ffmpeg -y -i /sdcard/FFMPEG/in.mp4 -c:v libx264 -b:v 2600k -pass 2 -c:a copy /sdcard/FFMPEG/out3.mp4
    , error still happens.

    so I then added -strict -2 -passlogfile /tmp/mydummy and ran ran
    ffmpeg -y -i /sdcard/FFMPEG/in.mp4 -c:v libx264 -strict -2 -passlogfile /sdcard/FFMPEG/ -b:v 2600k -pass 2 -c:a copy /sdcard/FFMPEG/out3.mp4
    , and same error still happens.

    My question is, how to use ffmpeg "-pass" in termux successfully without especially entering the target folder ?

  • Clarification on using FFmpeg in an open source app with —enable-gpl and —enable-nonfree [closed]

    24 avril 2020, par Alex Hoffman

    Can someone please clarify the legality of bundling and using the full version of FFmpeg (with included libx264 and libx265 and other gpl codecs) in an open source app.

    



    I don't want to modify anything, all I want to do is to bundle compiled FFmpeg binaries downloaded from their website with my open source app which would use them for media files editing.

    



    I want to bundle the full version of FFmpeg since without --enable-gpl and --enable-nonfree, not being able to process h264, FFmpeg becomes effectivelly useless. So I want to know if I have to bundle the binaries compiled without --enable-gpl and --enable-nonfree or can I bundle the full version with shared linking (libs separated from the executable) ?
