I have tried almost every suggestion on how to make subtitles work, in windows it works all the time, on android it does not. I see the required libraries in the output.
The command:
ffmpeg -y -i "input.mp4" -vf subtitles=MySubtitle.srt "output.mp4"
I see this error message
"W/mobile-ffmpeg: [graph 0 input from stream 0:0 # 0x752e80aa90] sws_param option is deprecated and ignored"
but I can't find help on it.
Below is the output of ffmpeg:

I found several issues: I hope this notes helps others
the format of hour:minute:second,miliseconds (note the comma for miliseconds, and colons for others.
bug: I was putting my seconds into the minute slot,
conversion error when time was rolling upwards would not roll the seconds into minutes
check the last line of subtitle.srt make sure the last time entry is not zeros
the time sequence must be continual, if any time stamp in between is smaller than previous, subtitle will not be displayed
if you break the sentence in two lines in subtitle.srt, it will display it as a wrapped line.

I have ffmpeg 5.0 installed on a new Silicon M1 Mac Mini running Monterey and concat is failing with the same command that has served me well on ffmpeg 4.1.1 lo, all these many years. Anyone have an idea why this command would fail on the newer version of ffmpeg.
This is with the exact same mp4 files. The ffmpeg 4.1.1. completes the concat in less than a minute.
ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4
Thank you!

Adding -vsync 0, as in
ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" -vsync 0 output.mp4
solved my problem.

I'm using FFMpeg locally on a Mac (actually using PHP-FFMpeg) and it's working perfectly. I'm running the same code on an Ubuntu server and whatever I try the output file is a tiny, low quality video with just 1 second length (the original is about 15 seconds).
I installed it on the server with
sudo apt update
sudo apt install ffmpeg
and then restarted the server. To test now I'm running
ffmpeg -i source.mp4 target.mp4
from the terminal and getting this output

Here's what the files look like
Any ideas what could be wrong?
Thanks for your help!
#llogan gave the perfect answer, see comments above. I ran this on the server to upgrade FFMpeg to the latest version and it's working correctly now
sudo add-apt-repository ppa:savoury1/ffmpeg4
sudo add-apt-repository ppa:savoury1/graphics
sudo add-apt-repository ppa:savoury1/multimedia
sudo apt full-upgrade
ffmpeg -version
The output file has the double duration :
Source video duration :00:01:58.88
output video duration :00:03:57.76
（video's duration is double ，audio's duration is correct. So， the video looks like played twice, with no sound in the second half ）
here is the log：

I want to convert first few seconds (say 5 seconds) of a video to multiple output formats using ffmpeg.
when I Use this syntax to convert whole video, everything goes ok:
(to be simple, i left all options to be default)
ffmpeg -i input.flv output1.mp4 output2.avi
but when trying for just first 5 seconds using this syntax:
ffmpeg -t 5 -i input.flv output1.mp4 output2.avi
first output file (i.e ouptput1.mp4) is ok and it is 5 seconds length, but the second (and next outputs, if present) has a size of original file.
this is what ffmpeg prints out on the screen.
D:\ffmpeg\bin>ffmpeg -t 5 -i input.flv output1.mp4 output2.avi

How is the correct syntax to get all output files same size?
isn't this a bug with ffmpeg? (note last lines of conversion progress, which all timestamps look same)
thanks in advance.
You need to add output options for each output:
ffmpeg -i input.flv -t 5 output1.mp4 -t 5 output2.avi
Consider adding an additional option for output quality--especially for the avi as libx264, if available, is the default for mp4 and the default options for libx264 are sane.
ffmpeg -i input.flv -t 5 output1.mp4 -t 5 -qscale 3 output2.avi
See FFmpeg: The ultimate Video and Audio Manipulation Tool for more information on -qscale (also called -q:v).
To save having to specify every file name you can use a FOR loop. This saves all flv and mp4 files as avi files with their original file names to a "NEW" folder. For use in a bat/cmd file:
md NEW
FOR /F "tokens=*" %%G IN ('dir /b *.flv') DO ffmpeg -y -i "%%G" -t 5 "NEW\%%~nG.avi"
FOR /F "tokens=*" %%G IN ('dir /b *.mp4') DO ffmpeg -y -i "%%G" -t 5 "NEW\%%~nG.avi"
