Allows the user to reserve space for the ODML master index. A sufficient sized master index in the AVI header avoids storing follow-up master indexes within the 'movi' data later. If the option is omitted or zero the index size is estimated from output duration and bitrate.

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.

Fixes the duration field of the OpenDML master index "indx" chunk to contain the number of samples instead of the number of packets for (linear/PCM) audio streams. This matches the OpenDML V1.02 standard text which states that the duration field shall contain "time span in stream ticks". Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).

It will be useful in the following commits. Also, rename the AVCodecContext pointer name from 'stream' to 'codec'.

Do not call an AVCodecContext 'stream', that is highly confusing. Also, add a local variable for the current AVStream in the loop over all streams.

Partially undoes commit 2c4e08d8: riff: always generate a proper WAVEFORMATEX structure in ff_put_wav_header A new flag, FF_PUT_WAV_HEADER_FORCE_WAVEFORMATEX, is added to force the use of WAVEFORMATEX rather than PCMWAVEFORMAT even for PCM codecs. This flag is used in the Matroska muxer (the cause of the original change) and in the ASF muxer, because the specifications for these formats indicate explicitly that WAVEFORMATEX should be used. Muxers for other formats will return to the original behavior of writing PCMWAVEFORMAT when writing a header for raw PCM. In particular, this causes raw PCM in WAV to generate the canonical 44-byte header expected by some tools. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
