Trick play mode related issue in gstreamer on i.MX6DL

[gauthamkanthara]

Hello,

Working on iMX6 target. I am trying to play a video file using gst pipeline "gst-launch playbin2 uri=file://<full path to sample file>", video and audio is fine until when I try to use trick play mode to seek to stream forward/backward for about xx seconds. What I see in the  vpudec and aiurdemux gstreamer plugin code is that some error states like "GST_FLOW_WRONG_STATE" are ignored during trick play mode handling i.e. in gst_vpudec_chain function and in aiurdemux_push_pad_buffer. Please let me know why these event types are ignored or the reason for it. Thank you.

Steps to reproduce the issue:

1) export GST_DEBUG=*:2

2) gplay <path to seekable video file>

3) Select option 'e' for seek

4) Select seek mode [Fast seek:0, Accurate seek:1]: either '1' or '0'

5) Accurate seek to percentage[0:100] or second [t?]: 10

Seek Output:

seeking: 0:00:59.000000000/0:09:56.459008000

Let me know if it is fine to ignore this state or is there any way to handle it?

Thank you.
