Thank you so much.

even i user 1024*768, the picture have Mosaic，but the Pi's cpu useage is only :28%, i use wlan to connect pi with my pc, the net i think is ok, so i really confused.

I have no rpi at this time, so i cannot help you a lot, yet i think your should try to lower the bitrate and force the baseline profile in raspivid command line parameters

See --profile baseline and --bitrate ??? https://www.raspberrypi.org/documentation/raspbian/applications/camera.md

@weicool888 , you received a mail because you "watch" this repository and asked to receive mail when someone create activity in it. Unwatch h264-live-player or toggle mail notification from github web interface.

hi,François, thank you for your reply. The "--profile" is default "baseline",but I don't think it's Raspi issue,please take a look at the bellow picture,it's raspi's cpu usage，I use wlan to connect pc with the pi,so it can't be the network speed issue, could you tell me where have the limit ? any parameter could be refine for it ? Thank you so much.

1080p30hz

@szhansen I got this issue too when streamed video from raspberry pi. Guess it might be problem in fps or decode in browser. Did you fix this?

@szhansen did you fix this problem? works fine in size 720X1080，but other size phone failed。
