• Error in compiling x264 on ARM 64-bit platform

  2 septembre 2021, par yanzhang.guo

  The same x264 source code I compiled on Debian 10 (Buster) system has no problem, but I can't compile it on an ARM 64-bit platform. Why ?

  


  Maybe there is something wrong with the Makefile, but I don't know where it is.

  


  


  1. Configure

     


     ./configure --disable-asm --enable-shared  --host=aarch64-linux

platform:      AARCH64
byte order:    little-endian
system:        LINUX
cli:           yes
libx264:       internal
shared:        yes
static:        no
asm:           no
interlaced:    yes
avs:           avxsynth
lavf:          no
ffms:          no
mp4:           no
gpl:           yes
thread:        posix
opencl:        yes
filters:       crop select_every
lto:           no
debug:         no
gprof:         no
strip:         no
PIC:           yes
bit depth:     all
chroma format: all


     


  


  2. Edit file config.mak,

• Changing mkv to mp4 with a batch script

  1er février 2021, par Hetsig

  What I want the .bat to do is to "scan" the files, in this case, .mkv, looking for streams (if there's more than a video stream and an audio stream you might need a matroska file). If you have an audio stream and a video stream, let's change the files as there's no reason to use matroska.

  


  Currently I have 10 seasons of a TV show, which I personally ripped from my own DVDs, and they are in .mkv format. But inside the .mkv there's only video and audio, the subtitles are separate.

  


  The only reason I want to change .mkv to .mp4 is that plex can't use .mkv.

  


  The current code I have to remove metadata on all .XXX in the folder :

  


  if not exist "%~dp1_temp" (
    goto foldercreate
    )
    else (
    goto continue
    )

:foldercreate
echo.
echo Created temp folder.
echo -
mkdir _temp
attrib _temp +h
set errorlevel=
:continue
for %%f in (*%~x1) do (
    title Fixing %%f...
    move "%%f" _temp >nul
    echo Currently fixing %%f...
    ffmpeg -xerror -hide_banner -i "%~dp1_temp\%%f" -map_metadata -1 -codec copy -map 0 "%~dp1%%f" -loglevel warning -stats
    if %errorlevel% neq 0 (
        pause
        )
    del "%~dp1_temp\%%f"
    echo -
    )
if %errorlevel% neq 0 (
    echo FFmpeg errored...
    pause
    )
echo All done! removing temp dir...
rmdir _temp /S /Q
timeout /t 2 /nobreak>nul

• How to add this line to FFMPEG batch command ? [closed]

  10 décembre 2020, par user7959439

  I inherited a batch command that takes every png file inside the folder (with the .exe and the command inside) and converts it into a webp file.

  


  for /r %%F in (*.png) do (
    ffmpeg.exe -y -i "%%F" -compression_level 6 "%%~dpnF.webp"
    if not errorlevel 1 if exist "%%~dpnF.webp" del /q "%%F"
)


  


  I want to add a line that at the same time checks for any mp4 files and converts them to gifs.

  


  This is the line

  


  ffmpeg -i input.mp4 -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 output.gif


  


  I tried something like but it doesn't work.

  


  for /r %%F in (*.png) do (
    ffmpeg.exe -y -i "%%F" -compression_level 6 "%%~dpnF.webp"
    if not errorlevel 1 if exist "%%~dpnF.webp" del /q "%%F"
)


for /r %%F in (*.mp4) do (
    ffmpeg.exe -y -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 "%%~dpnF.gif"
    if not errorlevel 1 if exist "%%~dpnF.mp4" del /q "%%F"
)
