gstreamer-ffmpeg-0.10.1-4.lvn6

File attached below.

When using a local file, it should be possible to get duration information and seek, using the ffmpeg FLV demuxer:

static int flv_read_header(AVFormatContext *s,
                           AVFormatParameters *ap)
{
    int offset, flags, size;

    s->ctx_flags |= AVFMTCTX_NOHEADER; //ok we have a header but theres no fps, codec type, sample_rate, ...

<snip>
    if(!url_is_streamed(&s->pb)){
        const int fsize= url_fsize(&s->pb);
        url_fseek(&s->pb, fsize-4, SEEK_SET);
        size= get_be32(&s->pb);
        url_fseek(&s->pb, fsize-3-size, SEEK_SET);
        if(size == get_be24(&s->pb) + 11){
            s->duration= get_be24(&s->pb) * (int64_t)AV_TIME_BASE / 1000;
        }
    }

Right now, it just shows "Streaming".
