Ciao a tutt
qualche settimana fa avevo aperto una discussione sull'upload di video su youtube da un pannello di controllo utilizzando le api. Per caricare i video utilizzavo uplodify e quando provavo a caricare file di grandi dimensioni(avevo fatto test con file di 78 e 110 mega), uplodify mi restituiva errore.
Non so spiegarmi come, ma lo stesso codice copiato in un'altro progetto ora funziona.
Ora ho questo problema: seleziono il file di grandi dimensioni, carico il file con uplodify, il file viene caricato su youtube e la mia applicazione rimane in attesa che youtube restituisca il videoID assegnato al video. Il problema è che dopo un pò di tempo l'esecuzione del codice si blocca e non mi restituisce il codice associato al video, ma il video è presente su youtube. Dato che devo salvare su un database il codice. questo è un problema.
Perchè accade questo?
Come posso caricare un file di grandi dimensioni senza utilizzare uplodify?
A qualcuno è mai capitato di carica un file di grandi dimensioni con le api di youtube?
Quì trovate un pò di codice:
