FFMPEG concat kullanarak aynı FPS ile videoya çerçeve eklemek, FPS çıkışını azaltır

Bir videoyu elde ettikçe bunları bir videoda derlediğim bir parça C # görüntü elde etme yazılımı geliştiriyorum.

Şu an bunu, resim sayısı istenen FPS çıktısı olan bir görüntüden bir video oluşturarak yapıyorum, bu soru için 5 FPS kullanacağız. 5 görüntüye kadar bekleyecek, böylece yeni karelerin ekleneceği ana video için 1 saniye çekim yapabilir. Bu videoyu oluşturmak için bu komutu kullanıyorum:

-framerate 5-start_number 1 -i "C: \ path \ - \ image \ Image_% 05d.jpg" -c: v libx264 -pix_fmt yuv420p -r 5 "C: \ path \ - \ output \ output.mp4"

Buradan, yeni oluşturulan 'join_vid.mp4'ün FPS'si, Şekil 1'de gösterildiği gibi, genellikle 4 FPS'ye düşüyor (ancak 3 FPS'ye düştüğünü gördünüz). 1 FPS'ye gelinceye kadar 1'de kalır.

Şekil 1

Sorum şu: Yeni resmimi videonun sonuna nasıl ekleyebilirim?

• Bırakarak çerçeveleri
• Tüm videonun her yeni resimle yeniden oluşturulması gerekiyor
• Çıktı dosyasının FPS'sini bırakmak

Şu an beni güldürdüğü için herhangi bir yardım büyük beğeni topluyor!

Bu gerçekten H264 PTS nesil hata nedeniyle. Yorumdaki önerim benim için çalışıyor. Ancak yazı sonunda yöntem de öyle.

İlk dosya için komut :

ffmpeg -framerate 5 -start_number 1 -t 1 -i "f%d.png" -c:v libx264 -pix_fmt yuv420p -r 5 -bf 0 initial.mp4

Tek tek kareler için komut :

ffmpeg -framerate 5 -i "f6.png" -c:v libx264 -pix_fmt yuv420p -bf 0 -r 5 next1.mp4
...
ffmpeg -framerate 5 -i "f10.png" -c:v libx264 -pix_fmt yuv420p -bf 0 -r 5 next5.mp4

Tek bir katılım :

list.txt:

file initial.mp4
file next1.mp4

ve

ffmpeg -f concat -i list.txt -auto_convert 1 -c copy with6.mp4

with6.mp4:

Diğer yöntem, komutlarınızı olduğu gibi tutmaktır, ancak önce MKV'ye mux, sonra da MP4'e yani.

ffmpeg -f concat -i concat.txt -c copy new_output.mkv

ffmpeg -i new_output.mkv -c copy new_output.mp4
