Appending a list of movie MP4s causes the sound to be dropped or garbled at some point
7 février 2020, par MarieMy process is in 3 steps
Step 1) Corresponding to each bitmap I have 00.JPG ... NN.JPG I combine a list of "SOURCE" mp3 audio into a single audio mp3 to produce matching 00.MP3 ... NN.MP3I had glitch here where one my mp3 was not of the correct Sample Rate, however a kind soul in this forum helped me fix that.
You can read the details here :When I append a silent audio (mp3) to an existing list of audio it garbles the final audio ?
Step 2) combine each mp3 from previous with a the filename matching bitmap to produce a movie .MP4
IOW,
- 00.JPG + 00.MP3 >> 00.MP4
- 01.JPG + 01.MP3 >> 01.MP4
- and so on
From this run of 24 subparts, I hand tested some of these movies against Whatsapp and they are accepted fine.
However, the final MOVIE.MP4 is not.
I will list below their info from ffprobe.Step 3) combine the list of movies from previous into a final MOVIE.MP4
This is where I have been having random issues typically with audio, currently this audio drops at about 20s from start. Corresponding to roughly movies parts 04.mp4 to 07.mp4I play the videos via VLC but Windows Media Player has even worse playback.
I am able to reproduce Step3 and thus MOVIE.MP4 with following batch file
rem 10:33 PM 2/6/2020
SET EXE="S:\_BINS\FFmpeg 4.2.1 20200112\bin\ffmpeg.exe"
SET ROOTPATH=.\
SET OUT_FILE="%ROOTPATH%MOVIE.MP4"
SET IN_FILES_LIST="%ROOTPATH%IN_FILES_LIST.TXT"
SET OPTIONS= -f concat -safe 0 -i %IN_FILES_LIST% -c copy -y %OUT_FILE%
SET INFO_FILE="INFO.TXT"
%EXE% %OPTIONS% 1> %INFO_FILE% 2>&1
rem PAUSEThe content of IN_FILES_LIST.TXT
file '00.mp4'
file '01.mp4'
file '02.mp4'
...
file '23.mp4'
file '24.mp4'(Step 2) uses the following :)
The following is ffprobe on the source audio MP3s (Step 1)

handler_name : SoundHandlerI have not been able yet to reproduce the issue with a smaller set of movies, in the meantime if you would to get a copy I would have to upload an archive to a link so you can have them on your side.
Alternatively, if you would like me to provide additional info from these steps let me know what commands and I will be happy to provide.
Thank you.

Appending a list of movies MP4s causes the sound to be dropped or garbled at some point
9 février 2020, par MarieUpdate I am able to reproduce the issue by concatenating 10 Hello.mp4 clips and see the audio drop out/garbled at about 5 seconds playback. This is via VLC latest 3.0.8 on Windows7 64bit. Window Player zero sound. Media Player Classic it plays fine all 10 audio or the word "Hello". The same movie when dragged onto Whatsapp the PC app plays OK but no sound if played from the Phone Whatsapp. Perhaps its my computer too slow in the production of this clip ??? I don’t know what to trust anymore.
I copied the same ffmpeg.exe onto my kid’s Windows10 laptop and was able to produce the same behavior with sound dropping out with VLC however Windows10 media player is able to play the audio without a glitch.
You can reproduce the same on your end with this batch file

My process is in 3 steps
Step 1) Corresponding to each bitmap I have 00.JPG ... NN.JPG I combine a list of "SOURCE" mp3 audio into a single audio mp3 to produce matching 00.MP3 ... NN.MP3I had glitch here where one my mp3 was not of the correct Sample Rate, however a kind soul in this forum helped me fix that.
You can read the details here :When I append a silent audio (mp3) to an existing list of audio it garbles the final audio ?
Step 2) combine each mp3 from previous with a the filename matching bitmap to produce a movie .MP4
IOW,
- 00.JPG + 00.MP3 >> 00.MP4
- 01.JPG + 01.MP3 >> 01.MP4
- and so on
From this run of 24 subparts, I hand tested some of these movies against Whatsapp and they are accepted fine.
However, the final MOVIE.MP4 is not.
I will list below their info from ffprobe.Step 3) combine the list of movies from previous into a final MOVIE.MP4
This is where I have been having random issues typically with audio, currently this audio drops at about 20s from start. Corresponding to roughly movies parts 04.mp4 to 07.mp4I play the videos via VLC but Windows Media Player has even worse playback.
I am able to reproduce Step3 and thus MOVIE.MP4 with following batch file

handler_name : SoundHandlerI have not been able yet to reproduce the issue with a smaller set of movies, in the meantime if you would to get a copy I would have to upload an archive to a link so you can have them on your side.
Alternatively, if you would like me to provide additional info from these steps let me know what commands and I will be happy to provide.
Thank you.

FFMPEG - Why can't i record a video for more than 10 seconds ?
12 février 2020, par gabrielI’m developing a screen recorder for windows with python but for some reason i can’t record the video for more than 10 seconds.However i can record the audio for more than 10 seconds.
Also i’m using :FFMPEG - to record the video with mp4 extension
PYAUDIO - to record the sound
TKINTER - to design the GUI
Since the problem is with the video recording i will leave the code that i used with ffmpeg :
"""
