How can I check the integrity of a video file (avi, mpeg, mp4...)?

"For windows, You can 'batch' check integrity for videos on current folder and all subfolders with this bat file:

checkvideo.bat

@echo off

set ""filtro=%1""
if [%filtro%]==[] (
set ""filtro=*.mp4""
)

for /R %%a in (%filtro%) do call :doWork ""%%a""

PAUSE
exit /B

:doWork
C:\ffmpeg\bin\ffmpeg.exe -v error -i %1 -f null - > ""%~1.log"" 2>&1


Use:

checkvideo.bat [filter]

If you don't give one filter, will get '*.mp4'.

Samples: checkvideo.bat checkvideo.bat *.avi

Setup: Download FFmpeg for Windows from here: ffmpeg.zeranoe.com/builds/ and unzip them Change C:\ffmpeg\bin\ in the bat file for the path where you have unzipped ffmpeg Put checkvideo.bat on a folder included in the Path or add his folder to Path environment variable

UPDATE: As of September 18,2020, the above link is no longer valid so Windows users can download FFmpeg form here or here"

"Easier version

for file in *.mp4; do ffmpeg -v error -i ""$file"" -f null - >error.log 2>&1; print ""$file""; done

This will print the file name as they are being processed.

error.log will contain the errors."

"Although this is an old post, and I'm sure there's other ways to valid video files now. However, for a full video file check, you can use mplayer.exe.
Using the below (.bat) script will recursively check video files and save validated ones in a integritychecked.log file (to skip next time its run).
if not ""%1"" equ """" (
pushd %1
) else (
pushd ""%~dp0""
)

setlocal EnableDelayedExpansion
for /F ""tokens=1,2 delims=#"" %%a in ('""prompt #$H#$E# & echo on & for %%b in (1) do rem""') do (
set ""DEL=%%a""
)

echo This script with validate video files in the folder/sub-folders. Please ensure mplayer.exe is accessible in PATH.
echo.
echo Either run this script from the desired (parent) directory or specify the directory when running this script. eg checkvideo.bat <full path>
echo.
pause
echo.

REM Append date and time to integritychecked.log file
