I found that the warning occurs here v4l2.c
But what can I do to prevent the function avformat_find_stream_info from
calling this message?
static int v4l2_read_close(AVFormatContext *ctx)
{
struct video_data *s = ctx->priv_data;
if (atomic_load(&s->buffers_queued) != s->buffers)
av_log(ctx, AV_LOG_WARNING, "Some buffers are still owned by the caller
on "
"close.\n");
mmap_close(s);
v4l2_close(s->fd);
return 0;
}
