* avformat: Avoid allocation for AVFormatInternalAndreas Rheinhardt2021-09-171-1/+1
| | | | | | | | | | | | | Do this by allocating AVFormatContext together with the data that is currently in AVFormatInternal; or rather: Put AVFormatContext at the beginning of a new structure called FFFormatContext (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVFormatInternal altogether. The biggest simplifications occured in avformat_alloc_context(), where one can now simply call avformat_free_context() in case of errors.

* avformat/ipmovie: Avoid reading packets during read_headerAndreas Rheinhardt2021-03-241-9/+9
| | | | | | | | | | They will be discarded anyway because this can only happen for invalid data. This already implies that the pkt won't be used at all when parsing the very first chunk when reading the header, so one can use NULL as argument and remove the av_packet_unref() on error.

| | | | | | | | | When one of these errors happens during ipmovie_read_packet(), an error is returned and the packet is cleaned up generically. And since 712d3ac539f30239b764d8621829dc9dc913da61 the same happens in ipmovie_read_header(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* Interplay MVE: Implement frame format 0x10Hein-Pieter van Braam2017-06-271-16/+52
| | | | | | | | | | | | | | | | | | | | This implements the 0x10 frame format for Interplay MVE movies. The format is a variation on the 0x06 format with some changes. In addition to the decoding map there's also a skip map. This skip map is used to determine what 8x8 blocks can change in a particular frame. This format expects to be able to copy an 8x8 block from before the last time it was changed. This can be an arbitrary time in the past. In order to implement this this decoder allocates two additional AVFrames where actual decoding happens. At the end of a frame decoding changed blocks are copied to a finished frame based on the skip map. The skip map's encoding is a little convulted, I'll refer to the code for details. Values in the decoding map are the same as in format 0x06. Signed-off-by: Hein-Pieter van Braam <hp@tmm.cx>
* Interplay MVE: Implement frame format 0x06Hein-Pieter van Braam2017-06-271-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | This implements the 0x06 frame format for Interplay MVE movies. The format is relatively simple. The video data consists of two parts: 16 bits per 8x8 block movement data a number of 8x8 blocks of pixel data For each 8x8 block of pixel data the movement data is consulted. There are 3 possible meanings of the movement data: * zero : copy the 8x8 block from the pixel data * negative : copy the 8x8 block from the previous frame from an offset determined by the actual value of the entry -0xC000. * positive : copy the 8x8 block from the current frame from an offset determined by the actual value of the entry -0x4000 Decoding happens in two passes, in the fist pass only new pixeldata is copied, during the second pass data is copied from the previous and current frames. The codec expects that the current frame being decoded to still has the data from 2 frames ago on it when decoding starts. Signed-off-by: Hein-Pieter van Braam <hp@tmm.cx>
* Interplay MVE: Refactor IP packet formatHein-Pieter van Braam2017-06-271-17/+29
| | | | | | | | Interplay MVE can contain up to three different frame formats. They require different streams of information to render a frame. This patch changes the IP packet format to prepare for the extra frame formats. Signed-off-by: Hein-Pieter van Braam <hp@tmm.cx>
* Interplay MVE: Implement MVE SEND_BUFFER operationHein-Pieter van Braam2017-06-271-5/+11
| | | | | | | | | | | Interplay MVE movies have a SEND_BUFFER operation. Only after this command does the current decoding buffer get displayed. This is required for the other frame formats. They are fixed-size and can't always encode a full frame worth of pixeldata. This code prevents half-finished frames from being emitted. Signed-off-by: Hein-Pieter van Braam <hp@tmm.cx>

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-231-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
