I.MX6 Video Decode Capability

[johnlangworthy]

Can anybody tell me how many 576p streams of H.264 can be decoded concurrently by the I.MX6 in hardware?

I need it to be 3, but I suspect the answer is 2. In which case, are there any software CODECs avaialble which we can use to decode the 3rd stream?

Thanks

Hello John,

That will depend on H264 profile (BP, MP or HP) / bitrate of your videos but i.MX6 vpu is in theory capable of decoding up to 8 D1@30fps in parallel. Waiting for product launch mid of next month, you will have to go through your local (D)FAE to get access to documentation or tools but there is a demo shown at FTF that demonstrate multiple video decoding : http://www.youtube.com/watch?v=czuMQWvDbys

Hi,

I am able to play 4 videos on I.MX 6 sabre-lite board. But when I am trying to play 6 videos is showing this error:

               createVideoSurface: max surfaces on device support on device0 exceeded

and playing only 4 videos while shooting this error continuously.

Does this mean that we can play only 4 videos max at a time...???

please help..

Regards

Ikshwaku

Were you ever able to get this resolved? I am getting the same error message when I try to go above 4 videos. Can you please advise on where to make changes?

Thanks

Tim

Yes, You need to patch the fsl gstreamer plugin and add vsmax=32  in this file /usr/share/vssconfig

Does the patch work for imx8mq ?

Hello Ikshwaku,

I confirm hardware can do more (again, depending on the bitrate / resolutions of your videos) and the link is a proof it is possible at least on Android, your issue looks more like a GUI / openGL(ES) configuration issue.
