Hello everyone,

I try to print a specific date and time on ts stream with ffplay. I use the 
name of the file to calculate the timestamp of the day and time of capture. I 
use this command line :

ffplay /Users/stan/Desktop/200501MEZ0600_N.MPG -vf 
"drawtext=text='%{pts\:gmtime\:1588305600\}':fontfile=/Library/Fonts/Arial.ttf:fontsize=48:fontcolor=white:box=1:boxborderw=6:boxcolor=black@0.75:x=(w-text_w)/2:y=h-text_h-20
 »

The Timestamp (1588305600) correspond at 2020:05:01 06:00:00. But when the file 
is played, the date is OK, but the time does not correspond to 06:00:00 but 
21:11:21, I suppose the PTS  are discorrupts in the file but is there a way to 
print the exact time I want to see on screen ?

Thank’s for your help.

Stan

Her the uncut console :
