i.MX8M SW Video Encoder Linux

choppad — Fri, 11 May 2018 23:40:24 GMT

Hello i.MX Community Gurus?

The i.MX8M does not have a Hardware based H.264 Video Encoder, rather the documentation says that the NXP i.MX8M uses a Software based H.264 Video Encoder. I have been unsuccessful in finding this software encoder. Will someone please provide this software encoder such that it can be leveraged throughout the i.MX8M community?

Thanks in Advance,

DeWayne

the yocto should contain these codec, if you need AACP, you can download from the link as below, pls focus on the "

Codecs and other Algorithms (2)":

i.MX 8M Evaluation Kit|NXP

for more detailed information about codec in the bsp, pls refer to the i.MX Linux® Release Notes

Joan:

I appreciate your response, however, the CODECs that are inclusive in that download are Audio CODECs. What I am inquiring about is the H.264 SW Video Encoder.

Please Advise,

Hello:

I have found the following SW Video Encoder solution that "should work" on i.MX8M, but not too sure. Will someone from the community please advise?

x264, the best H.264/AVC encoder - VideoLAN

x264 is a free software library and application for encoding video streams into theH.264/MPEG-4 AVC compression format, and is released under the terms of the GNU GPL.

I'm hoping that this helps!

you also can try to use build the gst-libav, then use the encoder there.

Hello Joan:

I appreciate your response. Will you please advise the steps to build gst-libav, and then subsequently how to "use the encoder there"?

one can refer to the linux user guide,. which tell you how to install gstreamer1.0-libav into rootfs, for the SW encoder, maybe the performance isn't good enough, customer needs to improve it by yourself.
