PR #22939 opened by Macdu URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/22939 Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/22939.patch
Replaces #22930 The atrac9 decoder by default tries to decode a whole superframe at a time. If the input size is not big enough for it, it will instead try to decode only some frames. However, right now, it will always return that it consumed a whole superframe, even if only a single frame was decoded. This PR makes it so that `atrac9_decode_frame` correctly returns how much of the input buffer it actually consumed. I did not include the second commit of #22930 because it is now unrelated to this change. Also there is no nice way to get the superframe sample size in `get_audio_frame_duration`. >From e397d732430b2fa4ebb1c66089f768a98ac85027 Mon Sep 17 00:00:00 2001 From: Macdu <[email protected]> Date: Mon, 27 Apr 2026 22:35:38 +0200 Subject: [PATCH] avcodec/atrac9dec: improve output of atrac9_decode_frame --- libavcodec/atrac9dec.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavcodec/atrac9dec.c b/libavcodec/atrac9dec.c index 3c18ae8b42..2f2f86bc58 100644 --- a/libavcodec/atrac9dec.c +++ b/libavcodec/atrac9dec.c @@ -817,7 +817,7 @@ static int atrac9_decode_frame(AVCodecContext *avctx, AVFrame *frame, *got_frame_ptr = 1; - return avctx->block_align; + return frames < s->frame_count ?
