  • Overlaying a transparent webm on an MP4 freezes at the start sometimes

    23 janvier 2021, par joshlat94

    I'm currently using the command
 ffmpeg -i mainvideo.mp4 -vcodec libvpx -i myoverlay.webm -filter_complex "overlay = 5:5" done.mp4
To overlay a transparent webm on top of my main mp4. But for some reason the output video is frozen for the first 1 second but the audio is completely fine.

    


    I've tried this command with other videos and it works sometimes but most of the time the first few frames seem frozen

    


    Edit.
I have two main mp4 files, broken_source.mp4 and working_source.mp4. Putting the overlay on broken_source results in the output having the first 1 second of video frozen (audio completely fine) but putting the same overlay on working_source.mp4 is perfect and has no issues

    


    Logs for putting the overlay on working_source :

    


    ffmpeg -i working_source.mp4 -vcodec libvpx -i chat.webm -filter_complex "overlay = 0:0" working_complete.mp4

    I am trying to make a short video in FFMPEG, where a word stays on screen for the duration of the video (0.5s). My FFMPEG code looks like this :

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\:\Windows\fonts\calibri.ttf':fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4

    However, I keep getting the following error (see below for full output) :

    Fontconfig error: Cannot load default config file
    [Parsed_drawtext_0 @ 000001c2918cef00] Using "C:/Windows/fonts/mingliub.ttc"

    I figured it had something to do with the path to the font file. I also tried copying the font file to my FFMPEG map and map the font path to the FFMPEG directory :

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf
    "drawtext=fontfile=‘C:\FFMPEG\bin\calibri.ttf':fontsize=18:
    fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4'

    This doesn’t work either. I do get an output video.mp4 video, but the font is wrong. Here is the full output I get. It is the same for both code examples above :

    c:\FFMPEG\bin>ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\\:\\\Windows\\\fonts\\\calibri.ttf':fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4

    SOLVED ! Apparently the problem was that the path to the font cannot contain a semicolon (i.e., "C :/". The code that worked is :

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf “drawtext=fontfile= /Windows/fonts/calibri.ttf:fontsize=18: fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text=word” output.mp4

  • ffmpeg converting JPG slideshow to MKV

    17 décembre 2018, par phol

    I am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat

    output.txt contents :

    ffconcat version 1.0
    file slide_0001.jpg
    duration 0.163
    file slide_0002.jpg
    duration 0.533
    file slide_0003.jpg
    duration 1.067
    file slide_0004.jpg
    duration 0.533
    file slide_0005.jpg
    etc.

    FFmpeg command :

    ffmpeg -i output.txt output.mkv

    I also tried :

    ffmpeg -i output.txt -c:v copy output.mkv

    However, when converting, the colours of the images become skewed.
    White becomes pink / purple and dark green becomes light green.
    The same happens when choosing different codecs and containers.
    Is there a way to solve this ?

    EDIT :
    I performed the same conversion again. I attached the log output as requested.
    However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).

    I tried to alter things with pix_fmt and -vf format as can be seen in the second log output. This did not solve the problem.

    Background info :
    The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.
