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 outputting - * 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 "internal.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; - - uint8_t *orig_extradata; - uint32_t orig_extradata_size; - - 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, {.i64 = 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 AVCodecID id) -{ - switch (id) { - case AV_CODEC_ID_MPEG4: - return BC_MSUBTYPE_DIVX; - case AV_CODEC_ID_MSMPEG4V3: - return BC_MSUBTYPE_DIVX311; - case AV_CODEC_ID_MPEG2VIDEO: - return BC_MSUBTYPE_MPEG2VIDEO; - case AV_CODEC_ID_VC1: - return BC_MSUBTYPE_VC1; - case AV_CODEC_ID_WMV3: - return BC_MSUBTYPE_WMV3; - case AV_CODEC_ID_H264: - return priv->is_nal ?
