From 575ec4e17d4e9824bc015651dc99f0c778402866 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Sun, 28 Aug 2011 17:21:56 +0200 Subject: [PATCH] avconv: add a context for options. Move stream maps to it. Eventually all non-global options should be stored in it. --- avconv.c | 79 +++++++++++++++++++++++++++++++++++++++++++++------------------- 1 file changed, 56 insertions(+), 23 deletions(-) diff --git a/avconv.c b/avconv.c index 92273f1..d1b99cd 100644 --- a/avconv.c +++ b/avconv.c @@ -100,9 +100,6 @@ static const OptionDef options[]; static const char *last_asked_format = NULL; static AVDictionary *ts_scale; -static StreamMap *stream_maps = NULL; -static int nb_stream_maps; - static AVDictionary *codec_names; /* first item specifies output metadata, second is input */ @@ -317,6 +314,42 @@ static int nb_output_streams = 0; static OutputFile *output_files = NULL; static int nb_output_files = 0; +typedef struct OptionsContext { + /* output options */ + StreamMap *stream_maps; + int nb_stream_maps; +} OptionsContext; + +static void reset_options(OptionsContext *o) +{ + const OptionDef *po = options; + + /* all OPT_SPEC and OPT_STRING can be freed in generic way */ + while (po->name) { + void *dst = (uint8_t*)o + po->u.off; + + if (po->flags & OPT_SPEC) { + SpecifierOpt **so = dst; + int i, *count = (int*)(so + 1); + for (i = 0; i < *count; i++) { + av_freep(&(*so)[i].specifier); + if (po->flags & OPT_STRING) + av_freep(&(*so)[i].u.str); + } + av_freep(so); + *count = 0; + } else if (po->flags & OPT_OFFSET && po->flags & OPT_STRING) + av_freep(dst); + po++; + } + + av_freep(&o->stream_maps); + + memset(o, 0, sizeof(*o)); + uninit_opts(); + init_opts(); +} + #if CONFIG_AVFILTER static int configure_video_filters(InputStream *ist, OutputStream *ost) @@ -2609,7 +2642,7 @@ static int opt_codec_tag(const char *opt, const char *arg) return 0; } -static int opt_map(const char *opt, const char *arg) +static int opt_map(OptionsContext *o, const char *opt, const char *arg) { StreamMap *m = NULL; int i, negative = 0, file_idx; @@ -2654,8 +2687,8 @@ static int opt_map(const char *opt, const char *arg) } if (negative) /* disable some already defined maps */ - for (i = 0; i < nb_stream_maps; i++) { - m = &stream_maps[i]; + for (i = 0; i < o->nb_stream_maps; i++) { + m = &o->stream_maps[i]; if (check_stream_specifier(input_files[m->file_index].ctx, input_files[m->file_index].ctx->streams[m->stream_index], *p == ':' ?
