Roland Scheidegger	9b9df1cdff	h264: new assembly version of get_cabac for x86_64 with PIC This adds a hand-optimized assembly version for get_cabac much like the existing one, but it works if the table offsets are RIP-relative. Compared to the non-RIP-relative version this adds 2 lea instructions and it needs one extra register. get_cabac() gets about 40% faster, for an overall speedup of about 5%. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Roland Scheidegger	14e9ffc1e4	h264: use one table instead of several for cabac functions The reason is this is easier for PIC code (in particular on darwin...). Keep the old names as pointers (static in cabac_functions.h so gcc knows these are just immediate offsets) so the c code can nicely stay the same (alternatively could use offsets directly in the functions needing the tables). This should produce the same code as before with non-pic and better code (confirmed) with pic. The assembly uses the new table but still won't work for PIC case. Signed-off-by: Ronald S.

Stefano Sabatini	6b55aab01a	lavfi: create buffer reference in filters which need to access the ref later Also add internal function ff_null_start_frame_keep_ref(). Fix crash when a following filter (e.g. settb) will unref the reference passed by start_frame(), and then the reference is accessed in end_frame() through inlink->cur_buf.	13 years ago

Martin Storsjö	df8aa4598c	mpegts: Make sure we don't return uninitialized packets This fixes crashes, where the demuxer could return 0 even if the returned AVPacket isn't initialized at all.
