[vlc-devel] vlc build problem ... recompile with -fPIC ??

[Mahesh Velankar]

Remi,
Thanks for looking into this.

What my original interest is, is about how VLC does not get into problem
when decoding AC3 audio when there is no sync_word found.

We have a transport stream with 3 audio streams. Out of these audio streams
our application (based on avlibs and ffmpeg) cannot decode audio stream 2
.... because it does not seem to have sync_word 0x770b found in the audio
data.

However VLC does not have any problem in decoding and playing all these
audio streams. And what I see is VLC is also using the same ffmpeg from
inside.
So I wanted to see how it is able to work around this audio stream that
ffmpeg rejects!!

This is the basic reason why I am trying to build VLC

Now about the srt....
I had tried to configure and make by disabling srt in
configure............That time it went to link next module and failed with
exactly same error ( -fPIC ... whatever)

I hope I have made it clear how I landed up here.
See if you can help me
Thanks again
