ffmpeg SpeedHQ codec decoding

Question

I am using ffmpeg for shq codec(SHQ2 and SHQ7).

Creating AVCodec with SHQ is fine:

codec = avcodec_find_decoder(AV_CODEC_ID_SPEEDHQ)

But this fails:

parser = av_parser_init(AV_CODEC_ID_SPEEDHQ);

So, I selected another solution(I configured the codec parser manually, then I get codec context by avcodec_parameters_to_context) not using parser.

Then I feed packet from 1080x1920 video stream as SHQ2 and SHQ7. 1920x1080 stream decoding is fine(if 1080x1920 image, it is fail).

It is fail from avcodec_send_packet function of FFmpeg when I decode packet.

For FFmpeg codec context, I am using AV_PIX_FMT_YUV422p(SHQ2), AV_PIX_FMT_YUVA422p(SHQ7) as format.

Now I can't parse packet, so finally I cant get AVFrame (beacuse of avcodec_send_packet fail).

Which parameter I need to update?
If you could give me a code snip for decoding SHQ 1080x1920 video packets with FFMpeg, I'd be happy.
