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.MP3
I 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.mp4
I 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 PAUSE
The 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)

The following is ffprobe on the MP3s concatenated with 2second Silence. All their Sample Rate 24K and Bit Rate 32k seems OK?? (Also Step 1)

I 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.
