Hello!

I have to encode big resolution, from 1Mpx (1280x1024) to 5 Mpx(2560x2048), in H264 and view video via RTSP, I have use live555 and Appro software. I succsefully get 3 Mpx (2048x1536), but with 4 Mpx (2368x1744) and 5 Mpx (2560x2048) I have small problem - I havn't error  when I encode data, but I see only vertical lines.

Where can I found recomendation or sample code for encode 4 Mpx (2368x1744) and bigest resolution?

Thank you and excuse me for my bad english.

    You must use latest Encode Library of H.264, V2.20. It support 4096x4096 resolution H.264 encode.

    Thank you for your reply!

    I use latest H264 codec and I have problem with image, but not with encode.

    And I solve this problem:
    h264_encoder_dm365_userguide.pdf (p. 80, 4-32):
    Note:
    In case of encodingPreset = XDM_HIGH_QUALITY, encoder supports
    encoding upto 4096x4096 resolution (MegaPixel). To enable Mega Pixel
    encoding, maxWidth should be given more than 2048 pixels. If
    Megapixel encoding is enabled SVC-T is disable internally.
    In case of encodingPreset =0 or encodingPreset =
    XDM_HIGH_SPPED, encoder support encoding upto 2048x2048
    resolution.
