About mkv file decoding in Linux 3.0.35.

Dear All,

 

[Issue]

A specific video file (.mkv) is loaded very slowly while playing. Meanwhile, the load of CPU is very high.

 

[Comment]

Device: i.MX 6Dual

We use gstreamer. And the version of gstreamer is 0.10.35 from “L3.0.35_4.1.0_130816_images_MX6” and “IMX_MMCODEC_3.0.35_4.1.0_BUNDLE_CODA.tar.gz”.
I don't think the VPU caused this bug. I think it's aiurdemux plugin.

Because only the aiurdemux thread has a high load of CPU.

 

[Command line]

$ gst-launch-0.10 -v filesrc location=/mnt/udisk1/sample.mkv ! decodebin2 name=dec dec. ! audioconvert ! audioresample ! alsasink dec. ! mfw_v4lsink

 

[Video information]

Container: .mkv (Matroska)

Video: H264 - MPEG AVC (part10) (avc1), 1280x720, 30fps

Audio: MPEG AAC Audio (mp4a), 48kHz

 

[Question]

Please resolve this issue.

 

Best Regards,

Keita
