[PR] avcodec/bsf/{eac3,truehd}_core: clear profile value on init() (PR #23957)

PR #23957 opened by James Almer (jamrial)
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23957
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23957.patch

The output stream no longer has Atmos metadata, so the AV_PROFILE_EAC3_DDP_ATMOS and AV_PROFILE_TRUEHD_ATMOS profiles, if they were set, are no longer valid.
