Hi
I've just started development on a streaming TV player using Theora as a
real
time encoder.
The player currently uses the majority of code in src/player_example.c. I
discovered a bug which was preventing the player from working correctly, but
which only showed up in my player; it didn't seem to affect the original
player_example.
I've now found the cause, which is indeed a bug in either player_example.c
or
libtheora itself. The example player declares a theora_state structure:
theora_state td;
Assumptions in libtheora assume that the element 'internal_encoder' (and
maybe
others) is initialised to NULL. This declaration doesn't guarantee that
condition and this turned out to be the cause of problems I was experiencing
in my player.
A simple memset() did the trick; not the tidiest of solutions but I couldn't
use theora_clear() from libtheora because this makes NULLness assumptions on
the structure as well. Maybe a modification to theora_decode_init() to clear
the appropriate fields?
