commit d2bb67cc7108a67791556b81869d9b6fa9d7ea8d Author: Romain Beauxis <[email protected]> AuthorDate: Thu Oct 15 15:03:01 2026 +0200 Commit: Romain Beauxis <[email protected]> CommitDate: Fri Oct 23 15:38:04 2026 +0000 tests/fate: show the pre-roll declared for AAC Print initial_padding and seek_preroll for aac-2048-priming.mov. The priming is the encoder delay at the start of the stream, while the pre-roll is how far before a seek target decoding has to start for the output to be reliable. Nothing declares a pre-roll for AAC. Also print it for HE-AAC with explicit SBR, where a frame is twice as many output samples, for SBR that does not double the sample rate, for AAC-LC with 960 samples frames, and for ELD. The references record the current output. --- tests/fate/aac.mak | 14 +++++++++++++- tests/fate/mov.mak | 4 ++++ tests/ref/fate/aac-seek-preroll-eld | 1 + tests/ref/fate/aac-seek-preroll-frame-length-short | 1 + tests/ref/fate/aac-seek-preroll-sbr | 1 + tests/ref/fate/aac-seek-preroll-sbr-no-doubling | 1 + tests/ref/fate/mov-aac-2048-priming-preroll | 1 + 7 files changed, 22 insertions(+), 1 deletion(-) diff --git a/tests/fate/aac.mak b/tests/fate/aac.mak index 52d6c5e925..4c4756a8f8 100644 --- a/tests/fate/aac.mak +++ b/tests/fate/aac.mak @@ -389,8 +389,20 @@ FATE_AAC_ENCODE_FFPROBE-$(call TRANSCODE, AAC, ADTS AAC, WAV_DEMUXER PCM_S16LE_D FATE_AAC_BSF-$(call FRAMECRC, AAC MATROSKA, AAC, AAC_PARSER AAC_ADTSTOASC_BSF MATROSKA_MUXER) += fate-aac-autobsf-adtstoasc +# The pre-roll a seek needs, by how long a frame is in output samples. +FATE_AAC_PREROLL-$(call DEMDEC, MOV, AAC) += fate-aac-seek-preroll-sbr \ + fate-aac-seek-preroll-sbr-no-doubling \ + fate-aac-seek-preroll-frame-length-short \ + fate-aac-seek-preroll-eld +fate-aac-seek-preroll-sbr: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_entries stream=profile,sample_rate,seek_preroll -print_format compact $(TARGET_SAMPLES)/aac/al_sbr_cm_48_2.mp4 +fate-aac-seek-preroll-sbr-no-doubling: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_entries stream=profile,sample_rate,seek_preroll -print_format compact $(TARGET_SAMPLES)/aac/al_sbr_sr_48_2_fsaac48.mp4 +fate-aac-seek-preroll-frame-length-short: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_entries stream=profile,sample_rate,seek_preroll -print_format compact $(TARGET_SAMPLES)/aac/al04sf_48.mp4 +fate-aac-seek-preroll-eld: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_entries stream=profile,sample_rate,seek_preroll -print_format compact $(TARGET_SAMPLES)/aac/er_eld2000np_48_ep0.mp4 + +FATE_SAMPLES_FFPROBE += $(FATE_AAC_PREROLL-yes) + FATE_SAMPLES_FFMPEG += $(FATE_AAC_ALL) $(FATE_AAC_FRAMECRC-yes) $(FATE_AAC_ENCODE-yes) $(FATE_AAC_BSF-yes) FATE_SAMPLES_FFMPEG_FFPROBE += $(FATE_AAC_ENCODE_FFPROBE-yes) -fate-aac: $(FATE_AAC_ALL) $(FATE_AAC_FRAMECRC-yes) $(FATE_AAC_ENCODE-yes) $(FATE_AAC_ENCODE_FFPROBE-yes) $(FATE_AAC_BSF-yes) +fate-aac: $(FATE_AAC_ALL) $(FATE_AAC_PREROLL-yes) $(FATE_AAC_FRAMECRC-yes) $(FATE_AAC_ENCODE-yes) $(FATE_AAC_ENCODE_FFPROBE-yes) $(FATE_AAC_BSF-yes) fate-aac-latm: $(FATE_AAC_LATM-yes) diff --git a/tests/fate/mov.mak b/tests/fate/mov.mak index ee3cd5e940..91e1699a5f 100644 --- a/tests/fate/mov.mak +++ b/tests/fate/mov.mak @@ -151,6 +151,10 @@ fate-mov-stream-shorter-than-movie: CMD = framemd5 -flags +bitexact -i $(TARGET_ fate-mov-aac-2048-priming: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_packets -print_format compact $(TARGET_SAMPLES)/mov/aac-2048-priming.mov +# The container's priming and the pre-roll a seek needs are different things. +FATE_MOV_FFPROBE-$(call DEMDEC, MOV, AAC) += fate-mov-aac-2048-priming-preroll +fate-mov-aac-2048-priming-preroll: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_entries stream=initial_padding,seek_preroll -print_format compact $(TARGET_SAMPLES)/mov/aac-2048-priming.mov + # Seeking into the stream must not drop samples to the container's priming.
