Ah, I thought this was in already, I was going to add some infom.
Let's have this, we can do more improvements or move it somewhere else
if necessary later on.
Acked-by: Victor Toso <victortoso@xxxxxxxxxx>
About what I was going to include is how the order of the messages in
spice.proto need to be in the same order of what is declared in the
protocol itself otherwise the (de)marshalling could be using the wrong
function to (un)serialize.
- full explanation just for reference
I'm playing with a new message to tell (or choose) the preferred video
codecs for streams. So I've included a new enum.h like:
(note that message is after gl-draw-done here)
--- a/spice/enums.h
+++ b/spice/enums.h
@@ -529,6 +529,7 @@ enum {
SPICE_MSGC_DISPLAY_STREAM_REPORT,
SPICE_MSGC_DISPLAY_PREFERRED_COMPRESSION,
SPICE_MSGC_DISPLAY_GL_DRAW_DONE,
+ SPICE_MSGC_DISPLAY_PREFERRED_VIDEO_CODEC_TYPE,
SPICE_MSGC_END_DISPLAY
};
But what I did on spice.proto was:
(the message is before gl-draw-done)
--- a/spice.proto
+++ b/spice.proto
@@ -984,6 +984,10 @@ channel DisplayChannel : BaseChannel {
} preferred_compression;
message {
+ video_codec_type codec_type;
+ } preferred_video_codec_type;
+
+ message {
} gl_draw_done;
};
The outcome in common/generated_server_demarshallers.c is
(...)
static parse_msg_func_t funcs2[5] = {
parse_msgc_display_init,
parse_msgc_display_stream_report,
parse_msgc_display_preferred_compression,
parse_msgc_display_preferred_video_codec_type
parse_msgc_display_gl_draw_done,
};
The handlers follow the order of spice.proto, meaning that on
demarshalling it was using parse_msgc_display_gl_draw_done() function
for SPICE_MSGC_DISPLAY_PREFERRED_VIDEO_CODEC_TYPE message.
;)
