PgGetLayerCaps(): querying layer capabilities problem   
When PgGetLayerCaps() is called to enumerate all layers and all layer's formats, the field format of the PgLayerCaps_t 
structure always contains an invalid values:

Layer 0
   Format: Unknown layer format: 0x00000020
Layer 1
   Format: Unknown layer format: 0x00000022
   Format: Unknown layer format: 0x00000022
   Format: Unknown layer format: 0x00000022
Layer 2
   Format: Unknown layer format: 0x00000020
   Format: Unknown layer format: 0x00000022
   Format: Unknown layer format: 0x00000026
   Format: Unknown layer format: 0x00000010
Layer 3
   Format: Unknown layer format: 0x00000020
   Format: Unknown layer format: 0x00000022
   Format: Unknown layer format: 0x00000026
   Format: Unknown layer format: 0x00000010

But must be:

Layer 0
   Format: Pg_LAYER_FORMAT_ARGB8888 (0x00000004)
Layer 1
   Format: Pg_LAYER_FORMAT_YUY2 (0x00010000)
   Format: Pg_LAYER_FORMAT_YVYU (0x00010002)
   Format: Pg_LAYER_FORMAT_UYVY (0x00010001)
Layer 2
   Format: Pg_LAYER_FORMAT_ARGB8888 (0x00000004)
   Format: Pg_LAYER_FORMAT_RGB565 (0x00000002)
   Format: Pg_LAYER_FORMAT_ARGB1555 (0x00000001)
   Format: Pg_LAYER_FORMAT_PAL8 (0x00000000)
Layer 3
   Format: Pg_LAYER_FORMAT_ARGB8888 (0x00000004)
   Format: Pg_LAYER_FORMAT_RGB565 (0x00000002)
   Format: Pg_LAYER_FORMAT_ARGB1555 (0x00000001)
   Format: Pg_LAYER_FORMAT_PAL8 (0x00000000)

According to http://community.qnx.com/integration/viewvc/viewvc.cgi/trunk/services/graphics/services.c?revision=1&root=
graphics&system=exsy1001&view=markup line 1335:

1335        if (gf_ph_layer_format(info.format,
1336 	    &rdata.get_layer_caps_reply.caps.format,
1337 	    &rdata.get_layer_caps_reply.caps.format_flags) == -1) {
1338 	    ret_code = ESRCH;
1339 	    break;
1340 	} 

There is a field format_flags in the PgLayerCaps_t structure, which is a part of reply message. But PgLayerCaps_t 
doesn't have such field, so I think that's why data in the structure has been displaced, and I obtain strange values 
instead of the layer format code.

what version, 641?  I think I fixed this recently.

RE: RE: PgGetLayerCaps(): querying layer capabilities problem   
Revision 224049 - (view) (download) (annotate) - [select for diffs] 
Modified Mon Jun 22 16:15:26 2009 UTC (5 months ago) by dleach 
File length: 52681 byte(s) 
Diff to previous 220622 
New convert routine gf_ph_layer_format() to provide
correct Pg_LAYER_FORMAT_XXXX format to PgGetLayerCaps().
Also fills in new format_flags member with 16-bit packing
or 32-bit byte-order depending on the layer format.

PR:69322
CI:ckeating



Line 1323 of services/graphics/services.c calls a new routine:

if (gf_ph_layer_format(info.format,
&rdata.get_layer_caps_reply.caps.format, 
&rdata.get_layer_caps_reply.caps.format_flags) == -1) { 
     ret_code = ESRCH; 
     break; 
}

New routine is:

int
gf_ph_layer_format(gf_format_t f, unsigned int * format, unsigned long *
format_flags) {
	uint32_t ret = 0;

	switch (f) {
		case GF_FORMAT_PAL8:

			(*format) = Pg_LAYER_FORMAT_ARGB1555;
			break;

		case GF_FORMAT_PKLE_RGB565:
		case GF_FORMAT_PKBE_RGB565:
		case GF_FORMAT_PACK_RGB565:
			(*format) = Pg_LAYER_FORMAT_RGB565;
			break;

		case GF_FORMAT_BGR888:
			(*format) = Pg_LAYER_FORMAT_RGB888;
			break;

		case GF_FORMAT_BGRA8888:
		case GF_FORMAT_ARGB8888:

			break;

		case GF_FORMAT_PKBE_YUV_YUY2:
		case GF_FORMAT_PACK_YUV_YUY2:
			(*format) = Pg_LAYER_FORMAT_YUY2;
			break;

		case GF_FORMAT_PKLE_YUV_YVYU:
		case GF_FORMAT_PKBE_YUV_YVYU:
		case GF_FORMAT_PACK_YUV_YVYU:
			(*format) = Pg_LAYER_FORMAT_YVYU;
			break;

		case GF_FORMAT_PKLE_YUV_V422:
		case GF_FORMAT_PKBE_YUV_V422:
		case GF_FORMAT_PACK_YUV_V422:
			(*format) = Pg_LAYER_FORMAT_V422;
			break;

		case GF_FORMAT_PACK_YUV_NV12:
			(*format) = Pg_LAYER_FORMAT_YUV_NV12;
			break;

		case GF_FORMAT_PACK_YUV_AYUV:
			(*format) = Pg_LAYER_FORMAT_YUV_AYUV;
			break;

		case GF_FORMAT_PLANAR_YUV_YVU9:
			(*format) = Pg_LAYER_FORMAT_YVU9;
			break;

		case GF_FORMAT_PLANAR_YUV_YV12:
			(*format) = Pg_LAYER_FORMAT_YV12;
			break;

		case GF_FORMAT_PLANAR_YUV_420:
			(*format) = Pg_LAYER_FORMAT_YUV420;
			break;

		default:
			ret = -1;
			break;
	}

	if (ret == 0) {
		if (f & GF_FORMAT_PACK)
			(*format_flags) = Pg_LAYER_FORMAT_PACK;
		else if (f & GF_FORMAT_PKLE)
			(*format_flags) = Pg_LAYER_FORMAT_PKLE;
		else if (f & GF_FORMAT_PKBE)
			(*format_flags) = Pg_LAYER_FORMAT_PKBE;
		else if (f & GF_FORMAT_BO_BGRA)
			(*format_flags) = Pg_LAYER_FORMAT_BO_BGRA;
		else if (f & GF_FORMAT_BO_ARGB)
			(*format_flags) = Pg_LAYER_FORMAT_BO_ARGB;
		else
			(*format_flags) = 0;
	}

	return ret;
}

Ah, ok :) But public Photon headers are not updated, as far as I can see.

really?  they should be every evening, maybe not the svn logs, but check
line 1323 on the foundry trunk ... in services.c

Sorry, my fault. I've messed up 6.4.1 headers with the local copy of svn repository :) Now I've updated svn repository 
and all looks fine.
