From d754ed41727b1fcbab335b510248a9758a73320c Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Fri, 30 May 2014 07:17:28 +0200 Subject: riffenc: take an AVStream instead of an AVCodecContext It will be useful in the following commits. Also, rename the AVCodecContext pointer name from 'stream' to 'codec'. --- libavformat/riffenc.c | 29 +++++++++++++++-------------- 1 file changed, 15 insertions(+), 14 deletions(-) (limited to 'libavformat/riffenc.c') diff --git a/libavformat/riffenc.c b/libavformat/riffenc.c index fe92bc56ae..8f0279628e 100644 --- a/libavformat/riffenc.c +++ b/libavformat/riffenc.c @@ -209,32 +209,33 @@ void ff_put_bmp_header(AVIOContext *pb, AVCodecContext *enc, avio_w8(pb, 0); } -void ff_parse_specific_params(AVCodecContext *stream, int *au_rate, +void ff_parse_specific_params(AVStream *st, int *au_rate, int *au_ssize, int *au_scale) { + AVCodecContext *codec = st->codec; int gcd; int audio_frame_size; /* We use the known constant frame size for the codec if known, otherwise * fall back on using AVCodecContext.frame_size, which is not as reliable * for indicating packet duration. */ - audio_frame_size = av_get_audio_frame_duration(stream, 0); + audio_frame_size = av_get_audio_frame_duration(codec, 0); if (!audio_frame_size) - audio_frame_size = stream->frame_size; + audio_frame_size = codec->frame_size; - *au_ssize = stream->block_align; - if (audio_frame_size && stream->sample_rate) { + *au_ssize = codec->block_align; + if (audio_frame_size && codec->sample_rate) { *au_scale = audio_frame_size; - *au_rate = stream->sample_rate; - } else if (stream->codec_type == AVMEDIA_TYPE_VIDEO || - stream->codec_type == AVMEDIA_TYPE_DATA || - stream->codec_type == AVMEDIA_TYPE_SUBTITLE) { - *au_scale = stream->time_base.num; - *au_rate = stream->time_base.den; + *au_rate = codec->sample_rate; + } else if (codec->codec_type == AVMEDIA_TYPE_VIDEO || + codec->codec_type == AVMEDIA_TYPE_DATA || + codec->codec_type == AVMEDIA_TYPE_SUBTITLE) { + *au_scale = codec->time_base.num; + *au_rate = codec->time_base.den; } else { - *au_scale = stream->block_align ? stream->block_align * 8 : 8; - *au_rate = stream->bit_rate ? stream->bit_rate : - 8 * stream->sample_rate; + *au_scale = codec->block_align ? codec->block_align * 8 : 8; + *au_rate = codec->bit_rate ? codec->bit_rate : + 8 * codec->sample_rate; } gcd = av_gcd(*au_scale, *au_rate); *au_scale /= gcd; -- cgit v1.2.3
