Current status of hardware reencoding

Recommended Posts

Hi all,

 

I've been reading a lot about VPU acceleration for h264 decoding and encoding. However, it seems that there is not much regarding transcoding (decoding + encoding). I would be interested in decoding 1080p h264 and encoding it back to 720p h264 in realtime. Ideally having that operation on 2 streams in parallel would be great.

 

I've seen that quite some work has been done in cedrus : https://linux-sunxi.org/Cedrus

 

As I can, h264 decoding seems to be supported but encoding is unclear. And there is obviously no comment about running both operations at the same time.

 

Since I would like to run a few tests and maybe help a bit, what hardware should I order ? Allwinner H3/H5/else ?

 

Thanks

Stick to H3 ATM.

Encoding should go but I am not dealing much in this area.

Mmm, is this applicable to Mainline, or the legacy kernel 3.4? My interest is entirely in mainline, but from browsing @@lex's repos, some of them appear to contain kernel headers for 3.4.
