segfault using x262 with asm
So I've got some renewed interest in MPEG-2 encoding and I thought I'd give x262 a whirl.
I'm using the latest code from http://git.videolan.org/git/x262.git and building in a simple Dockerfile per below: Code:
FROM buildpack-deps:focal as builder ARG MAKEFLAGS="-j4" RUN apt-get update && apt-get install -y --no-install-recommends \ yasm \ && rm -rf /var/lib/apt/lists/* RUN git clone http://git.videolan.org/git/x262.git && \ cd x262 && \ ./configure --enable static --enable-pic && \ make && \ make install Looks like the package manager in buildpack-deps:focal pulls in YASM 1.3.0 and gcc 9.3.0 which seems to work fine for x264 (I use this same base image to build that)
