From 00dd9a6d6a5c3cc209082023595354a81aff9bb9 Mon Sep 17 00:00:00 2001 From: Justin Ruggles Date: Tue, 20 Nov 2012 00:57:41 -0500 Subject: [PATCH] pcm: fix decoding of pcm_s16le_planar on big-endian The sample count is decremented by the DECODE() macro and needs to be reset in each loop iteration. Also, DECODE() increments the src pointer so that does not need to be done separately. --- libavcodec/pcm.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/libavcodec/pcm.c b/libavcodec/pcm.c index 906e8e83aa..a24a38ba80 100644 --- a/libavcodec/pcm.c +++ b/libavcodec/pcm.c @@ -338,15 +338,17 @@ static int pcm_decode_frame(AVCodecContext *avctx, void *data, break; case AV_CODEC_ID_PCM_S16LE_PLANAR: { + int av_unused n2; n /= avctx->channels; for (c = 0; c < avctx->channels; c++) { samples = s->frame.extended_data[c]; #if HAVE_BIGENDIAN - DECODE(16, le16, src, samples, n, 0, 0) + n2 = n; + DECODE(16, le16, src, samples, n2, 0, 0) #else memcpy(samples, src, n * 2); -#endif src += n * 2; +#endif } break; }
