Intel HEVC GACC and SW Encoder Look-Ahead problem

[Celio_A_]

I'm trying to encode HEVC with sample_multi_transcode with this par file

set -o::h265 e5400a06c74d41f5b12d430bbaa23d0b
-lad 100 -i::h264 input.264 -join -la_ext -hw -async 1 -n 300 -o::sink
-h 1080 -w 1920 -o::h265 output.hevc -b 3000 -join -async 1 -hw -i::source -l 1 -u 4 -n 300

sample_multi_transcode -par 1.par

Hi Celio,

Very apologized for late response, do you solve this issue yet?

I used your par file and reproduced the issue although the error message may be different, I will continue investigating before I submit a bug.

At the same time, could you give me some updated on this issue from your side?

Hi Mark

Ogolikov sayd that because Gacc and SW encoder have short LA only

Thanks,

Good to know your question was answered.

This looks like the limitation of SW/GACC codec.
