AVCodecParameters.sample_rate is a signed integer, so XMVAudioPacket.sample_rate should be, too. A negative sample rate doesn't make sense and triggers assertions in av_rescale_rnd. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

This reverts commit 25bacd0a. Since 230b1c07, the bytewise AV_W*() macros only expand their argument once, so revert to the more readable version of these. Signed-off-by: Martin Storsjö <martin@martin.st>

AV_WB32 can be implemented as a macro that expands its parameters multiple times (in case AV_HAVE_FAST_UNALIGNED isn't set and the compiler doesn't support GCC attributes); make sure not to read multiple times from the source in this case. Signed-off-by: Martin Storsjö <martin@martin.st>

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.

Since the number of channels is multiplied by 36 and assigned to to a uint16_t, make sure this calculation didn't overflow. (In certain cases the calculation could overflow leaving the truncated block_align at 0, leading to divisions by zero later.)

Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.
