Replying to [comment:1 Cigaes]:
> Please try the following patch:
> [http://ffmpeg.org/pipermail/ffmpeg-devel/2012-June/126277.html]
> Alternatively, you could try to use {{{-filter_complex}}} rather than
{{{-f lavfi}}}.
>
> Please also note that, while your command line is, strictly speaking,
correct, it produces a file with a single-channel audio stream that is not
declared as "mono" but as "front-left"; this is rather unusual. You can
fix it using the {{{pan}}} filter: {{{pan=mono:FC=FL}}}.
Thanks for your help. I tried the patch with both FFMPEG 0.11.1 and
0.10.2.git-f77fd34
Note: my libavdevice/lavfi.c file was slightly different in both cases,
here's what it looks like after I removed the 2 lines:
{{{
enum AVSampleFormat sample_fmts[] = { AV_SAMPLE_FMT_U8,
AV_SAMPLE_FMT_S16,
AV_SAMPLE_FMT_S32,
AV_SAMPLE_FMT_FLT,
AV_SAMPLE_FMT_DBL, -1 };
AVABufferSinkParams *abuffersink_params =
av_abuffersink_params_al$
abuffersink_params->sample_fmts = sample_fmts;
ret = avfilter_graph_create_filter(&sink, abuffersink,
inout->name, NULL,
abuffersink_params,
lavfi->grap$
}}}
Here is the command and output from FFMPEG 0.10.2.git:
