Hi All, I am using the below code where the channel layout I used is AV_CH_LAYOUT_STEREO.It is working fine.
snprintf(strbuf, sizeof(strbuf), "sample_fmts=%s:sample_rates=%d:channel_layouts=0x%"PRIx64,av_get_sample_fmt_name(AV_SAMPLE_FMT_S16), 44100,(uint64_t)AV_CH_LAYOUT_STEREO); err = avfilter_graph_create_filter(&aformat_ctx, aformat, NULL, strbuf,NULL, filter_graph); Bot when i use mono channel layout (below code)then voice of the song is different and the song is running bit fast. snprintf(strbuf, sizeof(strbuf), "sample_fmts=%s:sample_rates=%d:channel_layouts=0x%"PRIx64,av_get_sample_fmt_name(AV_SAMPLE_FMT_S16), 44100,(uint64_t)AV_CH_LAYOUT_MONO); err = avfilter_graph_create_filter(&aformat_ctx, aformat, NULL, strbuf,NULL, filter_graph); So please resolve the problem. Thanks & Regards, Vinay Yamusani.
