There are no guarantees that all side data types have the same representation on all platforms. Tests that change output due to this: id3v2-priv-remux, cover-art-mp3-id3v2-remux, gapless-mp3: SKIP_SAMPLES, which is tested by fate-gapless-mp3-side-data matroska-vp8-alpha-remux: MATROSKA_BLOCKADDITIONAL, which is tested by remux itself (side data is written into output) matroska-mastering-display-metadata: MASTERING_DISPLAY_METADATA and CONTENT_LIGHT_LEVEL, which are tested by ffprobe invocation in the same test matroska-spherical-mono-remux: STEREO3D and SPHERICAL, which are tested by ffprobe invocation in the same test segment-mp4-to-ts: MPEGTS_STREAM_ID, which is tested by ts remuxing tests webm-webvtt-remux: WEBVTT_IDENTIFIER/SETTINGS, which is tested by the ffprobe invocation in the same test mxf-d10-user-comments: CPB_PROPERTIES, which is tested by mxf-probe-d10 mov-cover-image: SKIP_SAMPLES, which is tested for mov by mov-aac-2048-priming copy-trac3074: AUDIO_SERVICE_TYPE, which is tested by fate-hls-fmp4_ac3
