Hi,
I've made a c++ class using libav that decodes input audio files into a
buffer of double values. It works fine.
Now, i want to handle live streams and add the observer/observee design
pattern so that external objects can perform various actions on each
read double buffer.
Could you try if avplay can work with it correctly?
I've made some tests:
* avplay plays the stream smoothly
* my program hangs on avformat_find_stream_info until the interrupt
calback returns 1
So, i've read avplay.c to see if it does something more than what i do.
Between lines 2249 and 2266, it sets up format_opts and opts
dictionnaries, then pass this last one to avformat_find_stream_info.
It seems that this is usefull if some specif format/codec is passed from
the command line, isn't it?
So, i still don't understand why avformat_find_stream_info hangs in my
code but not in avplay
thanks for your help
Florian
