Problema al enviar contenido al Chomecast

[Orru89 0]

¡Buenas tardes!

Escribo para pediros ayuda con un problema que estoy teniendo intentado reproducir contenido del servidor que tengo alojado en mi NAS Synology DS223j.

Al entrar en la app Emby de Android y seleccionar la opción de enviar a Chromecast, al intentar reproducir alguno de los archivos me sale el error de "Actualmente no hay transmisiones compatibles disponibles. Vuelva a intentarlo más tarde o póngase en contacto con el administrador del sistema para obtener más detalles". Antes creía que me pasaba con todos los archivos, pero ahora he podido ver que ocurre con algunos, mientras que otros se reproducen correctamente.

Me pasa en un Xiaomi Mi Stick, en un Chromecast de 2º generación y en el Chromecast integrado de una LG de 2024. Sin embargo, en un Fire Stick TV puedo reproducir el contenido sin problema, así como si lo reproduzco directamente en la app de Android en mi teléfono.

Adjunto logs del servidor.

¡Muchas gracias por vuestra ayuda!

The ffmpeg log is showing the reason for transcode as not having a 2 channel AC3 audio track with the correct language.

The log shows the stream information ffmpeg encounter as being different from the server's MediaSourceInfo data.
The following differences were found:

#0 Video H264 eng
    AspectRatio: 639:272 <=> 47:20

Then, while processing the DTS audio, it's logging a ton of the errors.

17:36:38.989 [matroska @ 0x4cc8210] Non-monotonous DTS in output stream 0:1; previous: 2011, current: 2000; changing to 2011. This may result in incorrect timestamps in the output file.
17:36:39.115 [matroska @ 0x4cc8210] Non-monotonous DTS in output stream 0:1; previous: 4090, current: 4080; changing to 4090. This may result in incorrect timestamps in the output file.
17:36:39.260 [matroska @ 0x4cc8210] Non-monotonous DTS in output stream 0:1; previous: 5754, current: 5744; changing to 5754. This may result in incorrect timestamps in the output file.

In a nutshell at least for this King Kong video the file itself has issues.

Some of the Chromecast devices you have might handle DTS, which may allow playback without the transcoding and may be able to handle the out of spec file.
I would try running the file through mkclean or MKVToolNix both found here:

@Orru89 is the problem just with this one file?

No, the problem happens with many files, but not with all of them.

I've have not tried what @Carlorecommended me as I don't really know how to use MkClean or MKVToolNix. But if it need to be done with every failing file it might be "too much work".

Thanks anyway!

Try downloading them. Open MKVToolNix and drag a file(s) over it and drop.
