Hi, BugMaster
I found the resson for error message. Because I compile the project by
vs2005 I change the structure "x264_cli_csps" from
const x264_cli_csp_t x264_cli_csps[] = {
[X264_CSP_I420] = { "i420", 3, { 1, .5, .5 }, { 1, .5, .5 }, 2, 2 },
[X264_CSP_I422] = { "i422", 3, { 1, .5, .5 }, { 1, 1, 1 }, 2, 1 },
[X264_CSP_I444] = { "i444", 3, { 1, 1, 1 }, { 1, 1, 1 }, 1, 1 },
[X264_CSP_YV12] = { "yv12", 3, { 1, .5, .5 }, { 1, .5, .5 }, 2, 2 },
[X264_CSP_YV16] = { "yv16", 3, { 1, .5, .5 }, { 1, 1, 1 }, 2, 1 },
[X264_CSP_YV24] = { "yv24", 3, { 1, 1, 1 }, { 1, 1, 1 }, 1, 1 },
[X264_CSP_NV12] = { "nv12", 2, { 1, 1 }, { 1, .5 }, 2, 2 },
[X264_CSP_NV16] = { "nv16", 2, { 1, 1 }, { 1, 1 }, 2, 1 },
[X264_CSP_BGR] = { "bgr", 1, { 3 }, { 1 }, 1, 1 },
[X264_CSP_BGRA] = { "bgra", 1, { 4 }, { 1 }, 1, 1 },
[X264_CSP_RGB] = { "rgb", 1, { 3 }, { 1 }, 1, 1 },
};
to
const x264_cli_csp_t x264_cli_csps[] = {
{ "", 0, { 0 }, { 0 }, 0, 0 },//[0]

{ "yv24", 3, { 1, 1, 1 }, { 1, 1, 1 }, 1, 1 },//[X264_CSP_YV24]
{ "nv12", 2, { 1, 1 }, { 1, .5 }, 2, 2 },//[X264_CSP_NV12]
{ "nv16", 2, { 1, 1 }, { 1, 1 }, 2, 1 },//[X264_CSP_NV16]

Here is wrong. The origin index corresponds to the index of name
"X264_CSP_*". The new index becomes "0,1,2....,11" after changed. The index
of csp "i422" becomes 2 from 4. The exact change in vs2005 as blows:
const x264_cli_csp_t x264_cli_csps[] = {
{ "", 0, { 0 }, { 0 }, 0, 0 },//[0]
{ "i420", 3, { 1, .5, .5 }, { 1, .5, .5 }, 2, 2 },//[X264_CSP_I420]
{ "yv12", 3, { 1, .5, .5 }, { 1, .5, .5 }, 2, 2 },//[X264_CSP_YV12]
{ "nv12", 2, { 1, 1 }, { 1, .5 }, 2, 2 },//[X264_CSP_NV12]
{ "i422", 3, { 1, .5, .5 }, { 1, 1, 1 }, 2, 1 },//[X264_CSP_I422]
{ "yv16", 3, { 1, .5, .5 }, { 1, 1, 1 }, 2, 1 },//[X264_CSP_YV16]
{ "nv16", 2, { 1, 1 }, { 1, 1 }, 2, 1 },//[X264_CSP_NV16]
{ "i444", 3, { 1, 1, 1 }, { 1, 1, 1 }, 1, 1 },//[X264_CSP_I444]
{ "yv24", 3, { 1, 1, 1 }, { 1, 1, 1 }, 1, 1 },//[X264_CSP_YV24]
{ "bgr", 1, { 3 }, { 1 }, 1, 1 },//[X264_CSP_BGR]
{ "bgra", 1, { 4 }, { 1 }, 1, 1 },//[X264_CSP_BGRA]
{ "rgb", 1, { 3 }, { 1 }, 1, 1 }//[X264_CSP_RGB]
};
All things wrong because of my misplay. Here is nothing about libswscale. I
amy sorry to waste your time. Thank you very much.
