Creazione di video da immagini con diverse SAR con FFMPEG

Sto cercando di eseguire il command ffmpeg :

ffmpeg -y -threads 2 -loop 1 -t 5 -i watermark-0.png -loop 1 -t 2.5 -i watermark-1.png -loop 1 -t 2.5 -iwatermark-2.png -loop 1 -t 2.5 -i watermark-3.png -loop 1 -t 2.5 -i4.png -loop 1 -t 2.5 -i watermark-5.png -loop 1 -t 2.5 -i watermark-6.png -loop 1 -t 2.5 -i watermark-7.png -filter_complex [1:v][0:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b1v];[2:v][1:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b2v];[3:v][2:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b3v];[4:v][3:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b4v];[5:v][4:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b5v];[6:v][5:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b6v];[7:v][6:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b7v];[0:v][b1v][1:v][b2v][2:v][b3v][3:v][b4v][4:v][b5v][5:v][b6v][6:v][b7v][7:v]concat=n=15:v=1:a=0,format=yuv420p[v] -map [v] -c:v libx264 -r 120 -s 1280x720 -aspect 16:9 -crf 1 -preset ultrafast output.mp4 

Ma ottengo l'errore ffmpeg: i primi parametri di collegamento in ingresso (dimensione 1280×720, SAR 5689: 5669) non corrispondono ai corrispondenti parametri secondi del collegamento di ingresso (1280×720, SAR 1: 1)

Lo stdout di ffmpeg è:

Quindi, cerco di specificare la SAR nel seguente command:

 ffmpeg -y -threads 2 -loop 1 -t 5 -i watermark-0.png -loop 1 -t 2.5 -i watermark-1.png -loop 1 -t 2.5 -iwatermark-2.png -loop 1 -t 2.5 -i watermark-3.png -loop 1 -t 2.5 -i4.png -loop 1 -t 2.5 -i watermark-5.png -loop 1 -t 2.5 -i watermark-6.png -loop 1 -t 2.5 -i watermark-7.png -filter_complex [0:v]setsar=1[sar0];[1:v][sar0]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b1v];[1:v]setsar=1[sar1];[2:v][sar1]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b2v];[2:v]setsar=1[sar2];[3:v][sar2]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b3v];[3:v]setsar=1[sar3];[4:v][sar3]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b4v];[4:v]setsar=1[sar4];[5:v][sar4]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b5v];[5:v]setsar=1[sar5];[6:v][sar5]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b6v];[6:v]setsar=1[sar6];[7:v][sar6]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b7v];[0:v][b1v][1:v][b2v][2:v][b3v][3:v][b4v][4:v][b5v][5:v][b6v][6:v][b7v][7:v]concat=n=15:v=1:a=0,format=yuv420p[v] -map [v] -c:v libx264 -r 120 -s 1280x720 -aspect 16:9 -crf 1 -preset ultrafast output.mp4 

Tuttavia, ho ancora l'errore esatto: I primi parametri di collegamento in ingresso (dimensione 1280×720, SAR 5689: 5669) non corrispondono ai corrispondenti parametri secondari di collegamento dell'ingresso (1280×720, SAR 1: 1)

Questa è la prima edizione. Il secondo problema è che ho bisogno di get questo command per eseguire anche con il filter Zoompan e non ho idea di where cominciare anche a get quel filter aggiuntivo per funzionare o where metterlo nel command.

Aiuto??

Devi impostare tutte le SAR in precedenza. Quindi, [1:v][sar0]blend=.. fallirà perché 1:v presenta ancora una SAR diversa. [sar1][sar0]blend=.. "functionrà e così via.

Può essere semplicemente più facile farlo in un command separato preventsvamente per each image di input e utilizzare l'output:

 ffmpeg -i watermark-5.png -vf setsar=1 watermark-5n.png
