video - quality - Conversión de Real Media con ffmpeg



ffmpeg tutorial (1)

Parece que su archivo contiene varias secuencias y cuando trabaje con ffmpeg, tendrá que seleccionar las que desea convertir. Uno supondría que desea un par de Audio / Video con la mejor calidad dentro del archivo. Aquí se explica cómo utiliza la opción "mapa" para dirigir transmisiones: http://trac.ffmpeg.org/wiki/How%20to%20use%20-map%20option

Si tuviera este archivo, usaría este comando:

ffmpeg -i [real-input-file] / -map 0:8 -map 0:7 / -c:v libx264 / -c:a libfaac -b:a 32k / output.mkv

Tengo varios viejos archivos crujientes de Real Media que necesito convertir y esperaba escribir un script para procesarlos en lote. Puedo hacer una conversión Real Media -> AVI con FFMpegX, pero cuando trato de replicar la conversión con ffmpeg, siempre falla con algo como:

[avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

Puede tener algo que ver con el formato funky de estos archivos Real Media:

¿Alguien tiene alguna sugerencia sobre cómo averiguar qué hace FFMpegX para que la conversión funcione, o sobre una mejor manera de utilizar ffmpeg para hacer esto?
