Qualcuno ha provato a elaborare il flusso da 13E/10949.34 V?

Dietro alcuni "antipasti" XML puoi vedere pezzi di mp4 (moof, mfhd, trafi, tfhd, tfdt, trun e mdat) ma quando l'ho tolto a mano con un po' di pulizia non ha funzionato, forse ce ne sono alcuni extra intestazioni che ingombrano la struttura e dovrebbero prima essere pulite ... O forse deve essere rimosso in un frammento più grande: m4s sembra pezzi MPEG-DASH.


Oltre a tutto questo, volano varie altre informazioni/configurazioni, ad esempio:

Ciao,
ho ottenuto più o meno gli stessi risultati tuoi.
Sicuramente sono "pezzi" di video MPEG_DASH.
Dopo ogni blocco xml ci dovrebbe essere la parte DASH, se ci fai caso ad esempio il file "845674551.m4s" viene spezzettato in 2 o 3 parti poi inizia quello successivo "845674552.m4s" che dura anche lui 2 o 3 parti.
Ho provato anche io a rimuover le parti xml per ottenere un "video" m4s ma non funziona.
Probabilmente come dici tu c'e da fare ancora "pulizia" di parti inutili.

Hi,
I got more or less the same results as you.
They are definitely MPEG-DASH video "chunks".
After each XML block there should be the DASH part. if you notice for example the file "845674551.m4s" is split into 2 or 3 parts then the next one "845674552.m4s" starts and it's split in 2 or 3 parts too.
I've tried to remove the xml parts to get a m4s "video" but it doesn't work.
Probably as you say there is still "cleaning" of unnecessary parts to be done.

Ciao!
 
Anche se non è DVB-NIP. Ma oggi hanno lanciato un altro promo (test Metadata) su 13E/11470.76V.
