Author: Anton Khirnov <[email protected]> Committer: Anton Khirnov <[email protected]> Date: Sun Oct 11 11:08:24 2015 +0200 flvdec: do not create any streams in read_header() The current muxer behaviour is to create streams in read_header() based on the audio/video presence flags, but fill in the stream parameters later when we actually get some packets for them. This is rather shady, since other demuxers set the stream parameters immediately when the stream is created and do not touch the stream codec context after that. Change the flv demuxer to behave in the same way as other similar demuxers -- create the streams only when we get a packet for them. --- libavformat/flvdec.c | 11 ++--------- 1 file changed, 2 insertions(+), 9 deletions(-) diff --git a/libavformat/flvdec.c b/libavformat/flvdec.c index 2375eb1..96504e7 100644 --- a/libavformat/flvdec.c +++ b/libavformat/flvdec.c @@ -558,20 +558,13 @@ static int flv_read_metabody(AVFormatContext *s, int64_t next_pos) static int flv_read_header(AVFormatContext *s) { - int offset, flags; + int offset; avio_skip(s->pb, 4); - flags = avio_r8(s->pb); + avio_r8(s->pb); // flags s->ctx_flags |= AVFMTCTX_NOHEADER; - if (flags & FLV_HEADER_FLAG_HASVIDEO) - if (!create_stream(s, AVMEDIA_TYPE_VIDEO)) - return AVERROR(ENOMEM); - if (flags & FLV_HEADER_FLAG_HASAUDIO) - if (!create_stream(s, AVMEDIA_TYPE_AUDIO)) - return AVERROR(ENOMEM); - offset = avio_rb32(s->pb); avio_seek(s->pb, offset, SEEK_SET); avio_skip(s->pb, 4); _______________________________________________ libav-commits mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-commits
