Arama sırasında ffmpeg'de garip hatalar alınıyor, "birlikte bulunan POC'ler kullanılamıyor", "mmco: unref short fail"
Başkalarının sorunu yaşadığını gördüm ancak bir çözüm görmedim. Ffmpeg ile aramaya çalışırsam bazı hatalar alıyorum ve ortaya çıkan video hareket etmeden önce başlangıçta bir karede donuyor. Videoyu VLC'de açsam bile, sorun ortaya çıktığında tam olarak o noktayı arayamam. Görünüşe göre video bir şekilde bozulmuş, ancak iyi oynuyor, düzeltilebilir mi?
Girişin kap formatını ts'den mp4'e değiştirirsem hata oluşmaz ancak donmuş çerçeve yerine siyah bir ekranım olur.
Tam komut ve çıktı:

Çözüldü ... önce:
ffmpeg -i video.ts -c copy video.mp4
ve bunun yerine:
ffmpeg -ss 5.5 -i video.mp4 -to 10 -avoid_negative_ts make_zero -vcodec libx264 -crf 23 -acodec copy output.ts
Yapmalısın:
ffmpeg -ss 5.5 -i video.mp4 -ss 0 -to 10 -avoid_negative_ts make_zero -vcodec libx264 -crf 23 -acodec copy output.ts
