  • Batch script calling its own name instead of files of a certain type ?

    27 juin 2020, par R. Elias
    cd %cd%
ffmpeg -i %cd%/%04d.png out.mp4


    



    A script with just this in it works completely fine and outputs exactly what I need it to, but :

    



    :: A simple script to convert a png or jpg image sequence to an         
mp4 file with ffmpeg
cls
@echo off
title PNG2MP4
color C
echo Ensure you have ffmpeg installed and setup in your environment variables or this script won't work.


:QUERY
echo This will convert all image files in the following directory to a single mp4, 
echo %cd%
echo are the files PNGs or JPEGs(PNG/P/JPG/J/CANCEL)?
set/p "ch=>"
if /I %ch%==PNG goto CONVERTPNG
if /I %ch%==P goto CONVERTPNG
if /I %ch%==JPG goto CONVERTJPG
if /I %ch%==J goto CONVERTJPG
if /I %ch%==CANCEL goto :eof
echo Invalid choice & goto QUERY

:CONVERTPNG
cd %cd%
ffmpeg -i %cd%/%04d.png out.mp4

:CONVERTJPG
cd %cd%
ffmpeg -i %cd%/%04d.jpg out.mp4


    



    This more complex version of the script fails, outputting :

    



    C:\tmp/img2mp4.bat4d.jpg: No such file or directory


    



    Why is it no longer calling the files that it did before and is there an easy fix for this ?

    


  • avfilter/vf_fps : properly preserve CEA-708 captions

    5 mai 2023, par Devin Heitmueller
    avfilter/vf_fps : properly preserve CEA-708 captions

    The existing implementation made an attempt to remove duplicate
    
captions if increasing the framerate, but made no attempt to
    
handle reducing the framerate, nor did it rewrite the caption
    
payloads to have the appropriate cc_count (e.g. the cc_count needs
    
to change from 20 to 10 when going from 1080i59 to 720p59 and
    
vice-versa).
    

    Make use of the new ccfifo mechanism to ensure that caption data
    
is properly preserved.

  • mpegts : Remove one memcpy per packet

    1er août 2013, par Ben Avison
    mpegts : Remove one memcpy per packet

    This was being performed to ensure that a complete packet was held in
    
contiguous memory, prior to parsing the packet. However, the source buffer
    
is typically large enough that the packet was already contiguous, so it is
    
beneficial to return the packet by reference in most cases.
    

             Before          After
    
         Mean   StdDev   Mean   StdDev  Change
    
memcpy    720.7  32.7     649.8  25.1   +10.9%
    
Overall  2372.7  46.1    2291.7  21.8    +3.5%
