>From 2529a34d6f2a517ddfe27de58ed1c9352b984110 Mon Sep 17 00:00:00 2001 From: Benjamin Larsson <[email protected]> Date: Sun, 5 Jan 2014 14:42:14 +0100 Subject: [PATCH] flv: Workaround for buggy Omnia A/XE encoder The Omnia A/XE encoder writes the explicit extra data incorrectly. It disables parametric stereo wrongly, as a fix truncate the extra data by setting the size to 2. The aac extra data parser will then only parse the correct parts. --- libavformat/flvdec.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/libavformat/flvdec.c b/libavformat/flvdec.c index c65c90c..a83c65b 100644 --- a/libavformat/flvdec.c +++ b/libavformat/flvdec.c @@ -915,6 +915,12 @@ skip: return ret; if (st->codec->codec_id == AV_CODEC_ID_AAC) { MPEG4AudioConfig cfg; + + /* Workaround for buggy Omnia A/XE encoder */ + AVDictionaryEntry *t = av_dict_get(s->metadata, "Encoder", NULL, 0); + if (!strcmp(t->value,"Omnia A/XE")) + st->codec->extradata_size = 2; + avpriv_mpeg4audio_get_config(&cfg, st->codec->extradata, st->codec->extradata_size * 8, 1); st->codec->channels = cfg.channels; -- 1.8.3.2
