Hola, tengo una consulta. Tengo dos audios ya sea pelicula o serie, uno en español y otro en inglés. En los móviles cuando me paso de audio no tengo problemas. Pero en el chromecast cuando paso de español de a ingles empieza a transcodificar. Cuál será el motivo?

Dev may have to explain more but the client does not support secondary audio so the media is actually being remuxed.

Es posible que el desarrollador tenga que explicar más, pero el cliente no admite audio secundario, por lo que los medios en realidad se están modificando.

18:53:17.830   Stream #0:0 -> #0:0 (copy)
18:53:17.830   Stream #0:2 -> #0:1 (copy)

The developer of google or emby?

Emby dev, but technically the casting device is causing the remux according to the log.

Emby dev, pero técnicamente el dispositivo de transmisión está causando el remux de acuerdo con el registro.

App: Emby for iOS 2.0.8

Hi, the reason is that the Chromecast can only play the first audio track in the file. 

So when the first video is Spanish but you want to play the 2nd audio track which is English the only way to accomplish this is to remux the audio so that the 2nd track is used and now is the 1st audio track.

This is the device shown above where Emby had to remux the file to change the audio track ordering correct?

Chromecast does not have an API to select secondary audio tracks, so when you select that track, the only way we can play it is with transcoding.
