* AVOptions: add functions for evaluating option strings.Anton Khirnov2011-10-12

* AVOptions: split get_number().Anton Khirnov2011-10-12
| | | | | Split actual writing to read_number() in the same way as write_number(). Allows set_string_number() to write to a caller-provided destination.
* AVOptions: add av_opt_get*, deprecate av_get*.Anton Khirnov2011-10-12
| | | | | New functions can get values from child objects, properly report error codes and have consistent naming and signatures.
* AVOptions: add av_opt_set*().Anton Khirnov2011-10-12
| | | | | | | Deprecate av_set_* New functions support setting values on children, return error codes instead of options and have consistent naming and signatures.
* AVOptions: add new API for enumerating children.Anton Khirnov2011-10-12
| | | | | | | | | 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.
* rv34: move inverse transform functions to DSP contextJanne Grunau2011-10-12

* flvenc: Write the right metadata entry countMartin Storsjö2011-10-12
| | | | | | | | 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>
* rtsp: Request that dynamic rate is disabledMartin Storsjö2011-10-12
| | | | | | | | | | | | | | | 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).

* h264: change unsupported bit depth message to error levelMans Rullgard2011-10-12
| | | | | | | Unsupported bit depth is certainly an error the user will want to know about. Signed-off-by: Mans Rullgard <mans@mansr.com>
* rtpdec: Read the packet length for all RTCP packet typesJohn Brooks2011-10-12
| | | | | | | | | | | 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>
* rtpdec: Fix the minimum packet length for RTCP SR packetsJohn Brooks2011-10-12
| | | | | | We actually read 20 bytes of these packets. Signed-off-by: Martin Storsjö <martin@martin.st>
* qdm2: fix signed multiplication overflowMans Rullgard2011-10-12
| | | | | | | | 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>
* flvdec: Don't export metadata entries that aren't proper metadataMartin Storsjö2011-10-12
| | | | | | | | | 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>
* flvdec: Split out setting of numeric fields from storing metadataMartin Storsjö2011-10-12

* libx264: support yuv422/444 output.Anton Khirnov2011-10-12

* sws: support yuv444p9/10 output.Anton Khirnov2011-10-12

* fix AC3ENC_OPT_MODE_ON/OFFJohn Stebbins2011-10-11
| | | | | | The values were reversed. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* h264: fix HRD parameters parsingMans Rullgard2011-10-11
| | | | | | | | | | 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().

* prores: implement multithreading.Ronald S. Bultje2011-10-11
| | | | | 60% speedup (overall decoding time) at 2 threads, and another 60% speedup at 4 threads.
* prores: idct sse2/sse4 optimizations.Ronald S. Bultje2011-10-11
| | | | ~3.0-3.5x as fast as original C version, 1.6x as fast overall.
* swscale: use aligned move for storage into temporary buffer.Ronald S. Bultje2011-10-11
| | | | The intermediate buffer is always aligned.

* h264: fix invalid shifts in init_cavlc_level_tab()Mans Rullgard2011-10-11
| | | | | | | | 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>
* intfloat_readwrite: fix signed addition overflowsMans Rullgard2011-10-11
| | | | | | | | | | 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. Signed-off-by: Mans Rullgard <mans@mansr.com>

* h264: fix detection of optional trailing PPS elementsMans Rullgard2011-10-11
| | | | | | | | | | | | | | The PPS may contain a few trailing elements whose presence is only signalled by data remaining after the the mandatory part has been parsed. The current code fails to take into account the rbsp_trailing_bits() when deciding whether to parse these optional elements. Assuming no unnecessary padding bytes are passed to this function, the optional elements are present if either more than 8 extra bits remain or the remaining bits do not form a valid rbsp_trailing_bits() after the mandatory PPS elements have been parsed.
