• Problems with FFMPEG concat and/or MP4BOX

  11 novembre 2016, par user3730954

  I’ve been searching for a reliable way to concat a large (>30) number of mp4 files.

  My methods so far have been trying the MP4BOX concat CLI, and FFMPEG’s concat filter (such as ffmpeg -auto_convert 1 -y -f concat -i files.txt -c copy out.mp4).

  Both tools produce the same problem : joining 2 or 3 files seems to work great, but any greater number produces a corrupted mp4 file (such as https://drive.google.com/file/d/0B_mWxBuwYcSgQjQtUnpQeUxVTm8/view). I can create a workaround where I join only 2 videos at a time, until all videos have been joined, but this does not work for an odd number of joins (i.e. 13).

  Why do these methods work on some files, but not others ?

  FFPROBE produces errors as you would expect on these corrupted files :

  error while decoding MB x y, bytestream z
  
  Reference 2 >= 2
  
  top block unavailable for requested intra mode

• Batch file runs in some folder and not others [duplicate]

  10 novembre 2020, par user1738673

  Final update : I have determined code that works in all folders, even those with lots of parentheses. It is as follows :

  


  FOR %%# IN ("*.flac") DO (Title %~nx0 Processing: %%~nx# 
            ffmpeg -i "%%~nx#" -ab 192k -map_metadata 0 -id3v2_version 3 "%%~n#.mp3"
            IF NOT ERRORLEVEL 1 IF EXIST "%%~nx#" DEL /q "%%~nx#")

ECHO Completed %~nx0

PAUSE


  


  The reason for the failure was a combination of parentheses in the folder names and hyphens in the filenames. The most important part of the final code is the double quotes. This resolved the problem with hyphens in the filename. It turned out to not be necessary to have cd /D "%~dp0." as the first line, so I removed it from the code. Thank you to everyone for all of your suggestions. I really appreciate the help and I am glad this was completely resolved.

  


  History Starts here :

  


  After all of the suggestions, here is the code to run in the folder of flac files :

  


  cd /D "%~dp0."

FOR %%# IN ("*.flac") DO (Title %~nx0 Processing: %%~nx#
                ffmpeg -i "%%~nx#" -ab 192k -map_metadata 0 -id3v2_version 3 "%%~n#.mp3")
                    
ECHO Completed %~nx0
PAUSE


  


  Here are my current troubleshooting steps as completed :

  


  I renamed the files in one of the folders in which it does not run to "a.flac", "b.flac", "c.flac", etc. That is to make sure it is not a filename related problem. It did not run.

  


  I renamed the folder itself to a single letter to make sure it was not a folder name issue (F:\MUSIC\j). It did not run.

  


  I copied the entire folder and gave it a new single-letter name (F:\MUSIC\y). It did not run.

  


  I copied the files to a newly-created single-letter named folder at the same directory level (F:\MUSIC\d). It did not work.

  


  I copied the flac files and bat file from the single-letter folder to a newly created single-letter folder. It did not run.

  


  So, I went back the original folder and RENAMED MY .bat FILE from single folder - flac to 192.bat to 192.bat. It ran perfectly.

  


  I went back and renamed the .bat file in all folders described above. They all ran perfectly.

  


  Next, I renamed my master .bat file to single_folder_flac_to_192.bat. I ran it in the original file folder with all of the original names for folder and files. It ran perfectly.

  


  I then copied it into each of the folder described above. It ran perfectly.

  


  I then went back to my original code and renamed it to 192a.bat. This still did not run in the original folder, but ran perfectly in the others I created.

  


  So, I renamed my original folder from F:\MUSIC\Yanni - Live At The Acropolis (1994) [FLAC] to ylata. It did not run.

  


  That is all I have time for before needing to go to work. More at lunch time.

  


  Original Post Starts Here :

  


  I am using Windows 10 Pro on my home PC.

  


  I have a batch file which uses ffmpeg to create mp3 from flac and then delete the flac. It runs perfectly in most folders of music. The code is here :

  


  FOR %%a IN ("*.flac") DO (Title %~0 Processing: %%~na.flac
            ffmpeg -i "%%~na.flac" -ab 192k -map_metadata 0 -id3v2_version 3 "%%~na.mp3"
            if not errorlevel 1 if exist "%%~pna.flac" del /q "%%~pna.flac")
ECHO Completed %~n0
PAUSE
                 


  


  In some folders, when I run the batch, it just blinks and goes away. Yes- there are flac files in the folders.

  


  I have checked the different music folders for their properties (read only, access, etc.) and they look identical. The file names are "normal". It doesn't matter which drive I copy the folder into, the results are the same.

  


  I have run the file as Administrator and get the same result.

  


  What else should I be looking into ?

  


• ffmpeg streams video to local file but doesn't stream it to remote ffserver

  5 juin 2015, par randomuser1

  I’m using ffmpeg to stream video from my webcam. I managed to save video to a file on my hard drive by typing :

  ffmpeg -rtbufsize 1500M -f dshow -i video="SF Camera":audio="Microphone (Realtek High Definition Audio)" test1.webm

  and it works, I see the test1.webm output and can play it later on.
