Intento mezclar una transmisión elemental h264 y una transmisión de audio aac en un archivo mp4 con ffmpeg. La transmisión h264 se codificó con x264.
El mp4 muxed suena bien. Pero ffmpeg siempre arroja la advertencia "Las marcas de tiempo no están configuradas en un paquete para la secuencia 0".
Es una transmisión elemental, entonces, ¿dónde debería obtener marcas de tiempo? ¿Estoy haciendo algo mal o es simplemente ffmpeg?
