Subject: [PATCH] media: amphion: only insert the first sequence startcode for vc1l format
For some formats, the amphion vpu requires startcode
before sequence and frame, such as vc1, vp8.
But for V4L2_PIX_FMT_VC1_ANNEX_L, only the first sequence startcode
is needed, the extra startcode will cause decoding error.
So after seek, we don't need to insert the sequence startcode.
In other words, for V4L2_PIX_FMT_VC1_ANNEX_L,
the vpu doesn't support dynamic resolution change.
Fixes: 145e936380edb ("media: amphion: implement malone decoder rpc interface")
