Macro Definition Documentation

§ REBASE_PICTURE

#define REBASE_PICTURE	(	pic,
		new_ctx,
		old_ctx
	)

Value:

((pic && pic >= old_ctx->picture &&                                       \
      pic < old_ctx->picture + MAX_PICTURE_COUNT) ?                           \
        &new_ctx->picture[pic - old_ctx->picture] : NULL)

§ UPDATE_PICTURE

#define UPDATE_PICTURE ( pic )

Value:

do {\
    ff_mpeg_unref_picture(s->avctx, &s->pic);\
    if (s1->pic.f && s1->pic.f->buf[0])\
        ret = ff_mpeg_ref_picture(s->avctx, &s->pic, &s1->pic);\
    else\
        ret = ff_update_picture_tables(&s->pic, &s1->pic);\
    if (ret < 0)\
        return ret;\
} while (0)

Function Documentation

§ ff_mpv_common_defaults()

void ff_mpv_common_defaults ( MpegEncContext * s )

Set the given MpegEncContext to common defaults (same for encoding and decoding).

The changed fields will not depend upon the prior state of the MpegEncContext.

§ ff_mpv_common_init()

av_cold int ff_mpv_common_init ( MpegEncContext * s )

init common structure for both encoder and decoder.

this assumes that some variables like width/height are already set

§ ff_mpv_decode_defaults()

void ff_mpv_decode_defaults ( MpegEncContext * s )

Set the given MpegEncContext to defaults for decoding.

the changed fields will not depend upon the prior state of the MpegEncContext.
