IMX6D 3.14.52 VPU

ispsubb — Mon, 20 Mar 2017 02:56:16 GMT

产品在imx6d ，3.14.52 这个版本上进行开发。我们在接收 (通过WIFI) iphone airplay 码流时，imx6在某些场景的码流是不能解码的，表现的现象为卡屏，且不会自动恢复。附件里面有一段在imx6播放的过程中录制的一段H264的码流（附件中的Airplay.264)。

这段H264码流在PC上用播放器播放正常。在IMX6 上本地通过以下两种方式播放。

一，gst-launch

gst-launch-1.0 filesrc location=/root/Airplay.264 ! h264parse ! vpudec ! overlaysink sync=false async=false

视频的后半部分不能解码。

二，mxc_vpu_test.out

./mxc_vpu_test.out -D "-i /root/Airplay.264 -f 2 -a 60

表现异常情况更多。

Iphone airplay 中帧率不固定，最高可能到60fps 。在iphone手机横竖屏切换，或者播放iphone手机本地视频时，非常容易出现。@Qiang Li
