¿Cómo puedo transmitir un video sin marca de tiempo en ffmpeg?

Tengo un archivo h.264 en bruto y trato de transmitirlo a través de ffmpeg (recibir con ffplay). El problema es que el video se atasca en el receptor a veces y recibo estos errores:

En el lado de envío:

¿Necesito decirle de alguna manera a ffmpeg el tipo de video? Cuando uso ffplay localmente en el archivo original no tengo este problema.
