* | rmenc: more than 2 streams are not currently possible.Reimar Döffinger2012-04-291-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that just extending the RMMuxContext.streams array would avoid it. It is also possible that two audio streams will fail to mux correctly as well, though at least it should not crash for this reason. I do not feel like checking either of these. This patch fixes trac issue #1022 (at least it makes it exit with a proper error message instead of crashing). Signed-off-by: Reimar Döffinger <[email protected]>

| * h264: new assembly version of get_cabac for x86_64 with PICRoland Scheidegger2012-04-283-24/+121
| | | | | | | | | | | | | | | | | | | | 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 <[email protected]>
| * h264: use one table instead of several for cabac functionsRoland Scheidegger2012-04-286-48/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Bultje <[email protected]>

| | | | | | | | | | | | | | | | Skip to parse fields for additional independent substreams and its associated dependent substreams since libavcodec's E-AC-3 decoder does not support them yet. Signed-off-by: Justin Ruggles <[email protected]>

* | h264: new assembly version of get_cabac for x86_64 with PICRoland Scheidegger2012-04-283-25/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. There is a surprisingly large performance improvement over the c version (more so than the generated assembly seems to suggest) just in get_cabac, I measured roughly 40% faster for get_cabac on a K8. However, overall the difference is not that big, I measured roughly 5% on a test clip on a K8 and a Core2. Hopefully it still compiles on x86 32bit... Now that only one table is used, there's some chance even darwin as compiles this (apparently the label arithmetic used previously doesn't work if it involves symbols defined in a different file, thanks to Ronald S. Bultje for helping me with this). Signed-off-by: Michael Niedermayer <[email protected]>
