           Summary: [gst-ffmpeg] timestamp problems with h.264
                    transportstreams?
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gst-ffmpeg

The playback of transportstreams from astra hd-channels in h.264 is not
possible here with ffdec_h264.

I use the following minimal pipeline

"gst-launch-0.10 filesrc location=testfile.ts ! mpegtsdemux ! ffdec_h264 !
xvimagesink"

and it ends up in a diashow with lots of "GST_EVENT
gstevent.c:847:gst_event_new_qos: creating qos proportion 2,305689, diff
784089392, timestamp 0:00:02.019711111" and "basesink
gstbasesink.c:2699:gst_base_sink_is_too_late:<xvimagesink0> warning: There may
be a timestamping problem, or this computer is too slow." messages.

It runs on an Intel i7 Q720 with 8GB ram and ATI5870 so i don't think that this
computer is too slow.

Setting "sync=false" for xvimagesink shows a smooth playback for these files.

Inserting queues/parser doesn't solve it.

Any hints about this?

Thanks,
Thomas
