How to use the gst-launch to play unaligned raw video data files？

[dave]

I have a 426x240 nv12 data file. I use the following command to play it, the resulting playback picture is distorted:

gst-launch-1.0 filesrc location=426x240-nv12-25fps-5s.yuv ! videoparse format=nv12 width=426 height=240 framerate=1/1 ! videoconvert ! autovideosink

I suspect that this problem is related to byte alignment. The width of the above file is 426, which is not 4-byte aligned; for some other 4-byte-aligned files, such as 428x240, 640x480, etc., using such commands can be played correctly:

gst-launch-1.0 filesrc location=428x240-nv12-25fps-5s.yuv ! videoparse format=nv12 width=428 height=240 framerate=1/1 ! videoconvert ! autovideosink

my question is :

1.Is my guess correct? (Non-4-byte alignment causes playback exception)

2.How to use the gst-launch to play such a video file?
