The init_put_bits() function (in libavcodec/put_bits.h) takes a buffer and a buffer size (in bytes). Several of the encoders are passing the buffer size in bits, by multiplying the buffer size by 8. This is incorrect.
We saw this problem when encoding a ProRes (Anatoliy) file at size 4096x4096. Debugging showed that the buffer size was very large, and when multiplied by 8, it was interpreted as a negative number. This caused the init_put_bits() to zero out the buffer, leading to a crash. The attached patch fixes the argument to init_put_bits in all of the cases where the buffer size was multiplied by 8. You could use the patch or make the same change. Regards, Dyami
