ad8b6326aa vf_overlay: don't access a buffer reference that's been given away. 2012-07-20 21:07:51 +02:00

7155763b78 vf_drawtext: don't give up its own reference to the input buffer. 
Directly forwarding the input buffer to the next filter means that
drawtext no longer owns any references to it and thus shouldn't refer to
it in any way.

51a8049be8 vf_aspect: clear AVFilterLink.cur_buf in start_frame(). 
The buffer is passed on to the next filter, so we shouldn't keep any
pointers to it.

1749e12f45 cafdec: allow larger ALAC magic cookie 
It already skips any extra bytes at the end, and apparently there are some
samples in the wild with larger 'kuki' chunks.

73dc0db486 alac: output in planar sample format 
Avoids unneeded interleaving and allows for reusing the AVFrame output buffer
as the internal buffer for 24-bit and 32-bit sample size.
