Initial delay in transcoded video, from file to file

[João Gueifão]

Hi, I tried to search for this exact issue within the archives but was
unsuccessful.

My problem is that I am trying to transcode a video file present in my
hard-drive and output the result into a new file, in the same drive. The
issue is that, regardless of the input video file, I always get an initial
video freeze effect which lasts about 1.5 seconds on the produced file.
After that initial freeze, the video plays just fine on both VLC and
Windows Films and TV app.

My pipeline is as follows:

gst-launch-1.0.exe -e filesrc location=C:\\video\\EO_7.mp4 ! decodebin
name=decode ! videoscale ! videorate !
video/x-raw,width=854,height=480,framerate=25/1 ! x264enc pass=qual
bitrate=2500 key-int-max=50 ! mpegtsmux ! filesink
location=C:\\video\\out\\EO_7_out.ts


Any suggestions?


Thank you in advance.
