ffmpeg mkv to mp4 ile ses çıkarmadan siyah ekranda görüntüleniyor

0

Bir mkv videoyu mp4'e dönüştürmeye çalışıyorum, ancak kullandığım kodlarla çalışmıyor.

Genellikle bu 2 koddan birini kullanırım:

ffmpeg -i input.mkv -c:v copy -c:a copy output.mp4 ffmpeg -i input.mkv -acodec aac -strict -2 -ab 320k -c:v copy output.mp4

Video için her ikisini de dönüştürmeye çalışıyorum. Bu konuda hala yeni bir şeyim ve neden bu sonuçları aldığımı anlamıyorum.

Sonuç, hiçbir video veya sesi oynatmayacak yalnızca siyah bir ekran olan bir mp4.

Kod 1:

ffmpeg -i input.mkv -c:v copy -c:a copy output.mp4

Kayıtlar herhangi bir hata göstermiyor, sadece eklenerek çıkartılabilen bir uyarı var -flags +global_header. Çıktıyı nasıl test ediyorsunuz?

Windows media player ve photoshop kullanarak test ettim. Ben gif yapmaya çalışıyorum ama mp4 her iki uygulamada da açılamıyor. Vlc ile çalışır, ancak bir klip kaydetmeye çalıştığımda, klip wmp veya photoshop ile de açılamaz.

Ayrıca, senin ffmpegeski. Yeni bir yapı kullanmanız şiddetle tavsiye edilir. Görünüşe göre, Windows kullanıyorsunuz, Zeranoe'da yeni bir yapı alabilirsiniz .

Bunu çözdün mü? Aynı sorun var ve -pix_fmt yuv420p çözmedi.

Evet, bu benim sorunumu çözdü ...

Çıktınız 10 Bit video ( yuv420p10le) - Sanırım WMP ve diğer bazı oyuncular buna dayanamıyor.

Uyumluluk için, -pix_fmt yuv420pHDR yapmak istemiyorsanız veya renk gamını arttırmadıysanız, bugün video uygulamalarının çoğu için varsayılan olan 8-Bit kodlamaya geri dönerek videoyu dönüştürmeniz (yeniden kodlamanız) gerekir.
