Mans Rullgard	f59bb3d8f3	mathops: remove undefined behaviour from sign_extend() This function intentionally overflows the signed range on the left shift. Using this type-punning avoids errors from the overflow checker without disabling this test globally. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kostya Shishkov	42feaf4070	vc1: explicitly zero interlaced mode coding variables for progressive mode Both v->fcm and v->field_mode are used in common code, now they won't be reset for progressive frame after interlaced one causing writing past the frame end for example.

Jindrich Makovicka	67bbf07fb5	log.h: make AVClass a named struct 'struct AVClass' is used in the code since `641c7afe3c`, but AVClass is typedeffed as an anonymous struct. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Justin Ruggles	3e68b28221	fix ac3 encoder documentation some of the mode values were reversed	13 years ago

Anton Khirnov	3b3ea34655	Remove all uses of deprecated AVOptions API.	13 years ago
Anton Khirnov	8c5dcaad13	AVOptions: add av_opt_next, deprecate av_next_option. Just for naming consistency, no functional changes.	13 years ago
Anton Khirnov	dca055be3a	AVOptions: add functions for evaluating option strings.	13 years ago
Anton Khirnov	059a037fbd	AVOptions: split get_number(). Split actual writing to read_number() in the same way as write_number(). Allows set_string_number() to write to a caller-provided destination.	13 years ago
Anton Khirnov	41d9d51a72	AVOptions: add av_opt_get, deprecate av_get. New functions can get values from child objects, properly report error codes and have consistent naming and signatures.	13 years ago
Anton Khirnov	dac66da63d	AVOptions: add av_opt_set(). Deprecate av_set_ New functions support setting values on children, return error codes instead of options and have consistent naming and signatures.	13 years ago
Anton Khirnov	641c7afe3c	AVOptions: add new API for enumerating children. This will allow the caller to enumerate child contexts in a generic way and since the API is recursive, it also allows for deeper nesting (e.g. AVFormatContext->AVIOContext->URLContext) This will also allow the new setting/reading API to transparently apply to children contexts.	13 years ago
Janne Grunau	1bca8f4bc5	rv34: move inverse transform functions to DSP context	13 years ago
Martin Storsjö	cad0c375d9	flvenc: Write the right metadata entry count No application rely on this count being correct as far as I know, but if we write a nonzero count value, it might just as well be the right one. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	76b0d03d82	rtsp: Request that dynamic rate is disabled DSS enables this automatically if streaming VOD over TCP. If enabled, the server feeds packets faster than realtime, screwing up RTCP NTP based timestamps. Also, DSS doesn't indicate that this was indicated, if it was enabled automatically (although if it was requested to be enabled, a header saying that it was enabled is added, but this isn't added if it is enabled automatically), making it even harder to detect and work around properly without explicitly asking for it to be disabled(/enabled, if we were able to support it).

Mans Rullgard	318efbfc10	h264: change unsupported bit depth message to error level Unsupported bit depth is certainly an error the user will want to know about. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
John Brooks	07b77fe387	rtpdec: Read the packet length for all RTCP packet types This allows skipping past unsupported RTCP packet types, as RFC 3550 section 6.1 mandates. Currently this only has any practical effect if a sender puts an unrecognized type before RTCP_BYE in a compounded packet, or (incorrectly) does not put RTCP_SR first. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
John Brooks	5d6ecf5345	rtpdec: Fix the minimum packet length for RTCP SR packets We actually read 20 bytes of these packets. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	c682514a8f	qdm2: fix signed multiplication overflow This code relies on the result wrapping as for unsigned values, and the sign is not used. Thus an unsigned type is proper here. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Martin Storsjö	5e87222fd1	flvdec: Don't export metadata entries that aren't proper metadata This avoids writing these entries doubly if transcoding from flv to flv, since the muxer blindly writes any and all metadata keys set, in addition to the fixed fields that the muxer always writes. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	b204c46d9d	flvdec: Split out setting of numeric fields from storing metadata Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

John Stebbins	5f3fb59953	fix AC3ENC_OPT_MODE_ON/OFF The values were reversed. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Mans Rullgard	fdba370f8a	h264: fix HRD parameters parsing The bit_rate_value_minus1 and cpb_size_value_minus1 elements allow a wider range than get_ue_golomb() supports. This adds a get_ue_golomb_long() function supporting up to 31 leading zeros, which is the maximum for these syntax elements, and uses it in decode_hrd_parameters().

Mans Rullgard	8babfc033e	h264: fix invalid shifts in init_cavlc_level_tab() The level_code expression includes a shift which is invalid in those cases where the value is not used. Moving the calculation to the branch where the result is used avoids these. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	88d1e2b2b0	intfloat_readwrite: fix signed addition overflows These additions might overflow the signed range for large input values. Converting to unsigned before the addition rather than after avoids such undefined behaviour. The result under normal two's complement wraparound remains unchanged.
