FFMPEG sendcmd command limitation
18 novembre 2022, par Stahlaugei try to draw text into a video with
drawtext
andsendcmd
.
In thesendcmd
file there are over 9100 commands defined (each frame needs a different text).
All my commands are build this way.

0 Parsed_drawtext_1 reinit 'text=\102030GA01, 102040Ap05
von oben, in Fließrichtung
[0,00] 17.11.2022 10\:22\:04:fontsize=28.928569157918293:y=5:x=0:fontcolor=#FFFFFF';

[0,00] 17.11.2022 10\:22\:05:fontsize=28.928569157918293:y=5:x=0:fontcolor=#FFFFFF';



My command is.


ffmpeg.exe -y -i "17112022_102204.mp4" -vf "sendcmd=f=drawtextcommands.cmd,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=black@1.0:line_spacing=5, drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=yellow@1.0:line_spacing=5,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=yellow@1.0:line_spacing=5,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=green@1.0:line_spacing=5" -c:v mpeg4 -qscale:v 5 -f mp4 "102030GA01_2022-11-17_10-21.mp4"



My
ffmpeg
Version is n5.0.4 lgpl.
If i run this command with the sendcmd file on my develop laptop it works just fine (i7-10850H and 32GB RAM) but if i run the excat same on a Surface (i5-1035G4 and 8GB RAM) or Dell Latitude 5175 (Intel m5-6Y57 and 8GB RAM) i get an error

[Parsed_sendcmd_0 @ 000002454188c540] No Targed specified in interval #XXXX, command #0 



where XXXX is different each time i run it. All PC runs Win 10.


I can´t really find the problem why i get this error on the tablets but not on my Laptop.
Maybe it´s a hardware ressource problem even FFMEG doesn´t have any requirements at all ?


I only can get it to run on the tablets if i delete lots of commands from the
sendcmd
file.
I can´t define excatly the amount i need to delete because each run i can have more or less commands that are working.
But i can say i need to delete a lot more commands on the Dell tablet then on the Surface on to get it to run.
