* mpegvideo: Fix undefined negative shifts in ff_init_block_indexLuca Barbato2016-03-05

* idct8x8: Fix undefined negative shiftsKaterina Barone-Adesi2016-03-05
| | | | | | | | | | | The original code left-shifts negative values, which is undefined in the C99 specification (the one used during normal Libav compilation). This change multiplies by (1 << shift), which is functionally equivalent, but has defined behavior. With this change, fate-idct8x8 compiled with --fsanitize=undefined works. Bug-Id: 686

* mov: Trim dref absolute pathVittorio Giovara2016-03-05
| | | | | | | | | | | | | Samples produced by Omneon (Harmonic) store external references with paths ending with 0s. Such movs cannot be loaded properly since every 0 is converted to '/', to keep the same parsing code for dref type 2 and type 18: this makes the external reference point to a non-existing direactory, rather than to the actual referenced file. Add a brief trimming loop that drops all ending 0s before trying to parse the external reference path. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | | | | Store the file duration in the same timebase it arrives (i.e. milliseconds) and only convert it to the file duration units (100ns) when it's actually written, thus simplifying some calculations. Also, store the duration as unsigned, since it cannot be negative. CC: libav-stable@libav.org Bug-ID: CVE-2016-2326

| | | | | The switch is not yet complete because the parsers and the bistream filters do not have a new AVCodecParam-based API yet.

* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
