> Hi,
> I have a recording pipeline which contains an encoder which makes use
> of intel’s quicksync under windows to produce an H264 stream which is
> muxed using mp4mux as part of splitmuxsink.
> This recorder normalizes the DTS and PTS so that DTS starts with 0.
> The produced videos can be played back using VLC and windows media
> player, repositioning and pause and resume are also possible.
> My gstreamer playback pipeline which uses splitmuxsrc and qtdemux can
> also playback the videos but has problems with pause, resume and re-
> positioning.
> I have traced the problems to the part of the demuxer where the
> cslg_shift correction takes place. cslg_shift contains the value
> 702356852. QTSTREAM_TO_GSTTIME(stream, stream->cslg_shift) returns
> 140471370400000 which leads to a ridiculous correction of the segment
> start and stop values.
> Has anyone any idea what my encoder is not doing which could explain
> what is happening here. I am using gstreamer 1.8.1
