2024-01-17optimized wire.js inbound function, reduce combine timesHEADmasterzengdongbao1-22/+33
If the frame data is large, it will be divided into multiple packets. In the current processing mode, each packet will be merged with the old packet into a new buffer, resulting in a large number of redundant operations. Optimization scheme: Use array cache packets, and finally use DataView.set to do a merge. After testing, 1080p picture data merging time can be reduced from 100ms to <5ms Signed-off-by: zengdongbao <zengdongbao@gmail.com>
2024-01-06fix keyboard mappings for international keyboard layoutsDavid Edler3-12/+166
Key presses by a client with an international keyboard layout will often fail. I.e. the key AltGr creates an error message "No mapping for key 255". This key is important to produce the @ symbol i.e. on German language keyboard. The currently used e.keyCode differs by browser vendor and is ambiguous for some keys. This change relies instead on the event.code, which is stable for most common keys and more complete. I keep the old implementation to rely on e.keyCode as a fallback if the e.code is not available or the mapping for it is missing.

2020-04-09Make an attempt to follow the rules on auto play videos.Jeremy White1-0/+5
Browsers have stopped allowing auto play videos. The documented solution is to mute your video. This patch mutes our videos and also attempts to start playing if the auto play does not fire. Acked-by: Frediano Ziglio <fziglio@redhat.com>

2019-12-31Check if streams array exists in handle_draw_jpeg_onloadJoel Purra1-1/+1
- It seems `SpiceDisplayConn` does not always have the array `this.o.sc.streams` set. - It also seems (stream?) images can be loaded before `streams` is set. - Without `streams`, or the specific stream matching `this.o.id`, `this.o.sc.streams[this.o.id].frames_loading` cannot be accessed. - The check for the specific stream woth `this.o.id` is already in place, this patch adds a check for `this.o.sc.streams` in `handle_draw_jpeg_onload`. - There might be a better place to ensure that `this.o.sc.streams` is initialized; this quick fix saved my bacon today though. Might be related to, and perhaps fix: - https://bugs.freedesktop.org/show_bug.cgi?id=94776 - https://bugzilla.redhat.com/show_bug.cgi?id=1323144 Signed-off-by: Joel Purra <mig@joelpurra.se>

2019-08-06Adjust the presentation of two byte scan codes.Jeremy White1-21/+17
The previous implementation worked strictly due to a bug which would luckily generate roughly the right scan codes, although we would send more codes than required. For example, the old implementation would send 0xdf48e0 for 'up key down' and '0xdfc8e0' for 'up key up'. The prepended 0xdf is incorrect; the correct values should be 0x48e0 and 0xc8e0. Essentially, it stored the bytes in reverse order and had a bug while flipping them. This code stores them in the order we transmit them which simplifies the code.

2019-02-15More reliable mouse position reportingspice-html5-0.2.1Cédric Bosdonnat1-10/+8
Depending on the structure of the page, the computed mouse position was not correct. Typically the case happend when there is no offset between the canvas and the view area, but an offset on the view area. The MouseEvent.offsetX and offsetY functions are now widely enough spread to use them and avoid complex computations.

2018-07-19display: Only use display channel with id 0Christophe Fergeau1-3/+4
spice-html5 does not support multiple display channels, and will only use the first one offered by spice-server, and ignore the others. This can cause issues when using a VM with a configured but unused org.spice-space.stream.0 spice port as this will create a 'fake' display channel which is offered by spice-server before the usual qxl display channel. This commit favours the display channel with id 0 rather than picking the first one. Signed-off-by: Christophe Fergeau <cfergeau@redhat.com> Acked-by: Frediano Ziglio <fziglio@redhat.com>
