You feed demuxed + * packets in one end and get decoded picture (fields/frames) out the other. + * + * Of course, nothing is ever that simple. Due, at the very least, to b-frame + * dependencies in the supported formats, the hardware has a delay between + * when a packet goes in, and when a picture comes out. Furthermore, this delay + * is not just a function of time, but also one of the dependency on additional + * frames being fed into the decoder to satisfy the b-frame dependencies. + * + * As such, a pipeline will build up that is roughly equivalent to the required + * DPB for the file being played. If that was all it took, things would still + * be simple - so, of course, it isn't. + * + * The hardware has a way of indicating that a picture is ready to be copied out, + * but this is unreliable - and sometimes the attempt will still fail so, based + * on testing, the code will wait until 3 pictures are ready before starting + * to copy out - and this has the effect of extending the pipeline. + * + * Finally, while it is tempting to say that once the decoder starts outputing + * frames, the software should never fail to return a frame from a decode(), + * this is a hard assertion to make, because the stream may switch between + * differently encoded content (number of b-frames, interlacing, etc) which + * might require a longer pipeline than before. If that happened, you could + * deadlock trying to retrieve a frame that can't be decoded without feeding + * in additional packets. + * + * As such, the code will return in the event that a picture cannot be copied + * out, leading to an increase in the length of the pipeline. This in turn, + * means we have to be sensitive to the time it takes to decode a picture; + * We do not want to give up just because the hardware needed a little more + * time to prepare the picture! For this reason, there are delays included + * in the decode() path that ensure that, under normal conditions, the hardware + * will only fail to return a frame if it really needs additional packets to + * complete the decoding. + * + * Finally, to be explicit, we do not want the pipeline to grow without bound + * for two reasons: 1) The hardware can only buffer a finite number of packets, + * and 2) The client application may not be able to cope with arbitrarily long + * delays in the video path relative to the audio path. For example. MPlayer + * can only handle a 20 picture delay (although this is arbitrary, and needs + * to be extended to fully support the CrystalHD where the delay could be up + * to 32 pictures - consider PAFF H.264 content with 16 b-frames). + */ + +/***************************************************************************** + * Includes + ****************************************************************************/ + +#define _XOPEN_SOURCE 600 +#include <inttypes.h> +#include <stdio.h> +#include <stdlib.h> +#include <unistd.h> + +#include <libcrystalhd/bc_dts_types.h> +#include <libcrystalhd/bc_dts_defs.h> +#include <libcrystalhd/libcrystalhd_if.h> + +#include "avcodec.h" +#include "h264.h" +#include "libavutil/imgutils.h" +#include "libavutil/intreadwrite.h" +#include "libavutil/opt.h" + +/** Timeout parameter passed to DtsProcOutput() in us */ +#define OUTPUT_PROC_TIMEOUT 50 +/** Step between fake timestamps passed to hardware in units of 100ns */ +#define TIMESTAMP_UNIT 100000 +/** Initial value in us of the wait in decode() */ +#define BASE_WAIT 10000 +/** Increment in us to adjust wait in decode() */ +#define WAIT_UNIT 1000 + + +/***************************************************************************** + * Module private data + ****************************************************************************/ + +typedef enum { + RET_ERROR = -1, + RET_OK = 0, + RET_COPY_AGAIN = 1, + RET_SKIP_NEXT_COPY = 2, + RET_COPY_NEXT_FIELD = 3, +} CopyRet; + +typedef struct OpaqueList { + struct OpaqueList *next; + uint64_t fake_timestamp; + uint64_t reordered_opaque; + uint8_t pic_type; +} OpaqueList; + +typedef struct { + AVClass *av_class; + AVCodecContext *avctx; + AVFrame pic; + HANDLE dev; + + AVBitStreamFilterContext *bsfc; + AVCodecParserContext *parser; + + uint8_t is_70012; + uint8_t *sps_pps_buf; + uint32_t sps_pps_size; + uint8_t is_nal; + uint8_t output_ready; + uint8_t need_second_field; + uint8_t skip_next_output; + uint64_t decode_wait; + + uint64_t last_picture; + + OpaqueList *head; + OpaqueList *tail; + + /* Options */ + uint32_t sWidth; + uint8_t bframe_bug; +} CHDContext; + +static const AVOption options[] = { + { "crystalhd_downscale_width", + "Turn on downscaling to the specified width", + offsetof(CHDContext, sWidth), + AV_OPT_TYPE_INT, 0, 0, UINT32_MAX, + AV_OPT_FLAG_VIDEO_PARAM | AV_OPT_FLAG_DECODING_PARAM, }, + { NULL, }, +}; + + +/***************************************************************************** + * Helper functions + ****************************************************************************/ + +static inline BC_MEDIA_SUBTYPE id2subtype(CHDContext *priv, enum CodecID id) +{ + switch (id) { + case CODEC_ID_MPEG4: + return BC_MSUBTYPE_DIVX; + case CODEC_ID_MSMPEG4V3: + return BC_MSUBTYPE_DIVX311; + case CODEC_ID_MPEG2VIDEO: + return BC_MSUBTYPE_MPEG2VIDEO; + case CODEC_ID_VC1: + return BC_MSUBTYPE_VC1; + case CODEC_ID_WMV3: + return BC_MSUBTYPE_WMV3; + case CODEC_ID_H264: + return priv->is_nal ?
