strftime %l pattern doesn't work on Windows build ( works on OSX just fine )

Reported by: Denis Owned by:

Description

Summary of the bug:

The following strftime pattern doesn't work on Windows platform:
%l : %M %p

it should show 1 digit hour ( %l ) as first symbol. If I replace it with %I ( 2 digit ) it works fine!
%l works on OSX just fine.

How to reproduce:

I use the following command line ( splitted by , ):

-i,(19).ASF,-bsf:v,h264_mp4toannexb,-f,mpegts,-t,3.2839843749999997,-an,-r,30,-c:v,mpeg4,-flags:v,+qscale,-global_quality:v,0,-vf,scale=1920:1080,drawtext= text=\'%{pts\:localtime\:1454166040\:'%Y-%m-%d'}\': bordercolor=black@0.5:borderw=4:fontfile=\'arial.ttf\':fontcolor=0xFFFFFF@1:x=w*0.0125:y=h*0.916-th:fontsize=66,drawtext= text=\'%{pts\:localtime\:1454166040\:'%l\:%M%p'}\': bordercolor=black@0.5:borderw=4: fontfile=\'arial.ttf\': fontcolor=0xFFFFFF@1:x=w*0.0125:y=h*0.975-th:fontsize=66,qYKocvopL0_tmp.tmp

the main problem here is the following part:
drawtext= text=\'%{pts\:localtime\:1454166040\:'%l\:%M%p'}\':

%l doesn't work as expexted on Windows platform

I tried all windows static builds versions from ffmpeg-2.8.6-win32-static.7z
And it doesn't work on any up to the current one.

Aren't you just reporting a deficiency of the Windows C runtime?

To make this a valid ticket please test current FFmpeg git head and provide a simplified command line that allows to reproduce the issue together with the complete, uncut console output.

comment:2 by Denis, 8 years ago

I don't really know what this bug is related to,but i see in docs that time pattern should be passed in strftime format. Which doesn't work well.
If I can pass time pattern in any other format just let me know and i will rework my code without looking for the fix from your side.

Please find test code on this link ( including the latest version of ffmpeg and 2 test .bat files one with %l and second with %I ).

Please reopen this ticket if anything in the FFmpeg documentation indicates that %l is supposed to work everywhere. (I think the exact opposite is correctly documented.)

comment:4 by Denis, 8 years ago

Thank you for the update. I got this but still has no solution for 12-hour with no leading zero format.

Can you please indicate in ffmpeg docs that strftime is platform specific function ( even compiled with GCC ) or so to avoid such tickets in future.

comment:5 by Carl Eugen Hoyos, 8 years ago

Afaict, the option is marked as deprecated usually meaning you get no or very limited support (including documentation) anyway: Additionally, it explains to read the documentation of strftime - I think it is obvious that only the platform-specific information can be meant.

Note: See TracTickets for help on using tickets.
