Hi, all,
I am developing a plug-in which obtains MPEG2 source and demux functionality. I
want to add forward scan and backward scan functionality. When rate is low(<
4.0), we can process it in decoder, but I want to implement scan with high
rate, maybe 32x and later. If so, this plug-in need start a new-segment and
send to all down-streaming plug-ins, and send data I picture by I picture. But
in my side, only 1st I picture is showed, why?
The detail is:
1.
Application send a segment to pipeline with rate 32.0 and
start time is 5 seconds
2.
When my plug-in receive this segment event, I find the
correspond I picture in 5 second time point.
3.
After sent flush-stop event, push this I picture with a
BUFFER DISCONT, time stamp is 5 second
REMARK: this picture can
be shown.
4.
Then I push 2nd I picture with a BUFFER DISCONT,
time stamp is 30 second, but this picture does not present.
REMARK: I using mpeg2dec
as my mpeg2 video decoder, I trace it, found it gst_push_pad this 1st
picture and not return, why?
Any friends have experience about trick mode can teach me, thanks very much.
Best Regards,
Ever Chen
