Marshmallow se sigue reiniciando. Parece un error de Stagefright. ¿Cómo saber qué archivo está causando el error?

Entonces, mi teléfono sigue reiniciándose cuando se inserta la tarjeta SD. Mirando el logcat, theres un montón de:

"FFmpegExtractor" y "stagefright"

antes de que el teléfono se reinicie.

Lo que sospecho es que tengo música o vídeos corruptos que hacen que stagefright se cuelgue y reinicie todo el sistema.

¿alguna idea de cómo saber cuáles son los archivos problemáticos? En el logcat, FFmpegExtractor y stagefright no listan el archivo que procesan :(

Gracias.
