Building on Arch, ffmpeg error

Compiling or Editing the Panda Source

The following command returned a non-zero value: g++ -std=gnu++11 -ftemplate-depth-70 -fPIC -c -o built/tmp/p3ffmpeg_composite1.o -Ibuilt/tmp -Ibuilt/include -DHAVE_SWSCALE= -DHAVE_SWRESAMPLE= -Ipanda/src/ffmpeg -fvisibility=hidden -pthread -fno-exceptions -msse2 -fno-strict-aliasing -ffast-math -fno-stack-protector -fno-finite-math-only -fno-unsafe-math-optimizations -O2 -Wall -Wno-unused-function -Wno-reorder -DBUILDING_FFMPEG panda/src/ffmpeg/p3ffmpeg_composite1.cxx

Help?

Could you share the actual compiler error, rather than just the command that failed?

It seems this fixes it, for version 6.0+, I guess… Im on 7.

      _audio_channels = codecpar->ch_layout.nb_channels;

      swr_alloc_set_opts2(
          &_resample_ctx,
          &_audio_ctx->ch_layout,
          AV_SAMPLE_FMT_S16,
          _audio_ctx->sample_rate,
          &_audio_ctx->ch_layout,
          _audio_ctx->sample_fmt,
          _audio_ctx->sample_rate,
          0, nullptr);

Looks like we already have a fix for this in Git. We will release 1.10.15 soon with this fix.
