From 3f9257c5a5b08bc9aa6f7b3e3535e1c5b086ec50 Mon Sep 17 00:00:00 2001 From: Justin Ruggles Date: Mon, 19 Dec 2011 23:53:04 -0500 Subject: [PATCH] idroqdec: set AVFMTCTX_NOHEADER and create streams as they occur. This fixes demuxing of file where the first packet is not audio. Such files are generated by our idroq muxer. It also fixes demuxing of audio only idroq files. --- libavformat/idroqdec.c | 27 ++++++++++++++------------- 1 file changed, 14 insertions(+), 13 deletions(-) diff --git a/libavformat/idroqdec.c b/libavformat/idroqdec.c index 5e347b1..d63c395 100644 --- a/libavformat/idroqdec.c +++ b/libavformat/idroqdec.c @@ -44,6 +44,7 @@ typedef struct RoqDemuxContext { + int frame_rate; int width; int height; int audio_channels; @@ -70,29 +71,21 @@ static int roq_read_header(AVFormatContext *s, { RoqDemuxContext *roq = s->priv_data; AVIOContext *pb = s->pb; - int framerate; - AVStream *st; unsigned char preamble[RoQ_CHUNK_PREAMBLE_SIZE]; /* get the main header */ if (avio_read(pb, preamble, RoQ_CHUNK_PREAMBLE_SIZE) != RoQ_CHUNK_PREAMBLE_SIZE) return AVERROR(EIO); - framerate = AV_RL16(&preamble[6]); + roq->frame_rate = AV_RL16(&preamble[6]); /* init private context parameters */ roq->width = roq->height = roq->audio_channels = roq->video_pts = roq->audio_frame_count = 0; roq->audio_stream_index = -1; + roq->video_stream_index = -1; - st = avformat_new_stream(s, NULL); - if (!st) - return AVERROR(ENOMEM); - avpriv_set_pts_info(st, 63, 1, framerate); - roq->video_stream_index = st->index; - st->codec->codec_type = AVMEDIA_TYPE_VIDEO; - st->codec->codec_id = CODEC_ID_ROQ; - st->codec->codec_tag = 0; /* no fourcc */ + s->ctx_flags |= AVFMTCTX_NOHEADER; return 0; } @@ -128,8 +121,16 @@ static int roq_read_packet(AVFormatContext *s, switch (chunk_type) { case RoQ_INFO: - if (!roq->width || !roq->height) { - AVStream *st = s->streams[roq->video_stream_index]; + if (roq->video_stream_index == -1) { + AVStream *st = avformat_new_stream(s, NULL); + if (!st) + return AVERROR(ENOMEM); + avpriv_set_pts_info(st, 63, 1, roq->frame_rate); + roq->video_stream_index = st->index; + st->codec->codec_type = AVMEDIA_TYPE_VIDEO; + st->codec->codec_id = CODEC_ID_ROQ; + st->codec->codec_tag = 0; /* no fourcc */ + if (avio_read(pb, preamble, RoQ_CHUNK_PREAMBLE_SIZE) != RoQ_CHUNK_PREAMBLE_SIZE) return AVERROR(EIO); st->codec->width = roq->width = AV_RL16(preamble); -- 2.7.4
