[Libav-user] Demuxers and probing

[valentinoffner at free.fr]

Hi,

I'm actually working on Libavformat for an internship and i have one question. 

I'd to integrate 2 specific-demuxers (audio et video) in libavformat, i didn't have to code them so I did it without any problem. 
 But now, if i try to open a specific audio file, both demuxers send AVPROBE_SCORE_MAX and probing fails :

Command line:

[AVIOContext @ 003f2e20] Statistics: 1048576 bytes read, 0 seeks
../audiofile.00: Invalid data found when processing input

So, my questions are :
-my problem can come from other thing that this 2 demuxers ?
-what happen if 2 demuxers get same score ? I've to recode demuxers to get 2 different scores or ffprobe can choose one of them ?

Thank you for the answer !
