From 48f30595f5db210885eddf2b2397236134fdcbbd Mon Sep 17 00:00:00 2001 From: Clément Bœsch Date: Thu, 17 May 2012 19:32:17 +0200 Subject: pan: use ff_parse_channel_layout() instead of av_get_channel_layout(). This allow specifying hexadecimal channel layout, and also handle the error printing internally. --- libavfilter/af_pan.c | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'libavfilter/af_pan.c') diff --git a/libavfilter/af_pan.c b/libavfilter/af_pan.c index d8c4116a07..0a1bf32061 100644 --- a/libavfilter/af_pan.c +++ b/libavfilter/af_pan.c @@ -34,6 +34,7 @@ #include "audio.h" #include "avfilter.h" #include "formats.h" +#include "internal.h" #define MAX_CHANNELS 63 @@ -98,7 +99,7 @@ static av_cold int init(AVFilterContext *ctx, const char *args0, void *opaque) { PanContext *const pan = ctx->priv; char *arg, *arg0, *tokenizer, *args = av_strdup(args0); - int out_ch_id, in_ch_id, len, named; + int out_ch_id, in_ch_id, len, named, ret; int nb_in_channels[2] = { 0, 0 }; // number of unnamed and named input channels double gain; @@ -111,11 +112,9 @@ static av_cold int init(AVFilterContext *ctx, const char *args0, void *opaque) if (!args) return AVERROR(ENOMEM); arg = av_strtok(args, ":", &tokenizer); - pan->out_channel_layout = av_get_channel_layout(arg); - if (!pan->out_channel_layout) { - av_log(ctx, AV_LOG_ERROR, "Unknown channel layout \"%s\"\n", arg); - return AVERROR(EINVAL); - } + ret = ff_parse_channel_layout(&pan->out_channel_layout, arg, ctx); + if (ret < 0) + return ret; pan->nb_output_channels = av_get_channel_layout_nb_channels(pan->out_channel_layout); /* parse channel specifications */ -- cgit v1.2.3
