Android HLS Streaming en utilisant .m3u8 url, obtenir un code d'erreur -1011 et le flux se bloque

Question

Je viens d'être amené sur un projet sur lequel un ancien employé travaillait alors je continue d'apprendre son code. Il y a eu un problème où, en streaming, le flux s'arrête aléatoirement.

L'application que j'utilise est connectée à un réseau, et sur le même réseau, il y a un dongle connecté à un plat en direct. Ce plat capte simplement les émissions en direct gratuites de la station de télévision locale et les convertit en streaming HLS qui peut être utilisé par l'appareil Android pour diffuser sur le lecteur Android natif.

Ce que j'ai trouvé dans les fichiers journaux autour du temps le flux arrête:

A 11: 34: 50,476, il y a un point où il n'y a pas de tampon disponible. Puis, à 11: 34: 51,081, il y a un message indiquant que PlaylistFetcher ne peut pas trouver le numéro de séquence, puis quelques lignes plus loin, il y a l'erreur suivante:

12-20 11:34:51.081 2706 29007 E LiveSession: XXX Received error -1011 from PlaylistFetcher. 

Quelle est l'erreur de session en direct -1011?

Answer 1

erreur Live Session -1011 est stagefright/MediaErrors.h:

MEDIA_ERROR_BASE  = -1000, 
... 
ERROR_END_OF_STREAM  = MEDIA_ERROR_BASE - 11, 

android.googlesource.com

On dirait que la source est allé AWOL et votre tampon d'entrée underflowed.
