Continuing the discussion from Lossless H264/HEVC:
usually answered by @DaneLLL but answers seem inconsistent.
according to these and other discussions it’s not clear, if it is supported or not and by which means.
is truly lossless encoding ( byte per byte) even possible?
Yes, it is byte-to-byte lossless
which codecs/compression?
H265
which systems? (xavier , xavier NX , tx2 )
TX2, Xavier and Xavier NX
which Jetpack versions?
After Jetpack 4.6
is it possible through the gstreamer framework or only through multimedia API framework?
It is supported in nvv4l2h265enc. The frame data has to be NV24 and enable the property:
enable-lossless : Enable lossless encoding for YUV444
flags: readable, writable, changeable only in NULL or READY state
Boolean. Default: false
what settings are required for supported frameworks? ( --elossless , qp=? which video format etc.)
Please refer to this post: Can tx2nx decode YUV444? - #3 by DaneLLL
expected performance (roughly)?
The performance listed in module data sheet is for encoding YUV420. For encoding YUV444, we don’t have exact data but it may be worse
thank you for fast reply, I’ll try to check it out and report back.
very helpful and ordered :)
P.S about future plans, i wanted to know if there are any plans for future release to expand either available formats / codecs and/or add further support
