commit 5d21502ecffb794333a53bb1fec4155ceb382ae4 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/mov: add a test for seeking into AAC with container priming Decode 0.15 s of the mono AAC-LC aac-2048-priming.mov starting at 2.3 s, with the seek done on the input. The seek lands in the middle of a frame, and the reference output starts at the requested time with the partial frame. The decoder instead discards the first 1994 samples, as the container's 2048 samples of priming are applied to the first frame decoded after the seek, so the output starts late. The reference records the current output. --- tests/fate/mov.mak | 4 ++++ tests/ref/fate/mov-aac-2048-priming-seek | 10 ++++++++++ 2 files changed, 14 insertions(+) diff --git a/tests/fate/mov.mak b/tests/fate/mov.mak index 70d147f74f..ee3cd5e940 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 $(TARGET_SAMPLES)/mov/aac-2048-priming.mov +# Seeking into the stream must not drop samples to the container's priming. +FATE_MOV-$(call FRAMECRC, MOV, AAC, PCM_S16LE_ENCODER ARESAMPLE_FILTER VOLUME_FILTER) += fate-mov-aac-2048-priming-seek +fate-mov-aac-2048-priming-seek: CMD = framecrc -ss 2.3 -t 0.15 -i $(TARGET_SAMPLES)/mov/aac-2048-priming.mov -af volume=0,aresample -c:a pcm_s16le + fate-mov-zombie: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_streams -show_packets -show_frames -bitexact -print_format compact $(TARGET_SAMPLES)/mov/white_zombie_scrunch-part.mov fate-mov-init-nonkeyframe: CMD = run ffprobe$(PROGSSUF)$(EXESUF) -show_packets -print_format compact -select_streams v $(TARGET_SAMPLES)/mov/mp4-init-nonkeyframe.mp4 diff --git a/tests/ref/fate/mov-aac-2048-priming-seek b/tests/ref/fate/mov-aac-2048-priming-seek new file mode 100644 index 0000000000..fb0223e0d2 --- /dev/null +++ b/tests/ref/fate/mov-aac-2048-priming-seek @@ -0,0 +1,10 @@ +#tb 0: 1/44100 +#media_type 0: audio +#codec_id 0: pcm_s16le +#sample_rate 0: 44100 +#channel_layout_name 0: mono +0, 1994, 1994, 1024, 2048, 0x00000000 +0, 3018, 3018, 1024, 2048, 0x00000000 +0, 4042, 4042, 1024, 2048, 0x00000000 +0, 5066, 5066, 1024, 2048, 0x00000000 +0, 6090, 6090, 525, 1050, 0x00000000 -- To stop receiving notification emails like this one, please contact [email protected]. _______________________________________________ ffmpeg-cvslog mailing list -- [email protected] To unsubscribe send an email to [email protected]
