avformat/flvenc: add no_sequence_end flags for flvflags when split flv file by flv format at first, and cat flvs file into one flv file, the flv sequence end is be used, then the whole flv have many flv sequence end TAG. this flags can give user an option to ignore write sequence end TAG Signed-off-by: Steven Liu <lingjiujia...@gmail.com> Signed-off-by: Michael Niedermayer <mich...@niedermayer.cc> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=c8528e54e57810535b94ccecbc9c711d67dd710f --- libavformat/flvenc.c | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-) diff --git a/libavformat/flvenc.c b/libavformat/flvenc.c index 9080f58..99903f5 100644 --- a/libavformat/flvenc.c +++ b/libavformat/flvenc.c @@ -63,6 +63,7 @@ static const AVCodecTag flv_audio_codec_ids[] = { typedef enum { FLV_AAC_SEQ_HEADER_DETECT = (1 << 0), + FLV_NO_SEQUENCE_END = (1 << 1), } FLVFlags; typedef struct FLVContext { @@ -527,13 +528,17 @@ static int flv_write_trailer(AVFormatContext *s) FLVContext *flv = s->priv_data; int i; - /* Add EOS tag */ - for (i = 0; i < s->nb_streams; i++) { - AVCodecParameters *par = s->streams[i]->codecpar; - FLVStreamContext *sc = s->streams[i]->priv_data; - if (par->codec_type == AVMEDIA_TYPE_VIDEO && - (par->codec_id == AV_CODEC_ID_H264 || par->codec_id == AV_CODEC_ID_MPEG4)) - put_avc_eos_tag(pb, sc->last_ts); + if (flv->flags & FLV_NO_SEQUENCE_END) { + av_log(s, AV_LOG_DEBUG, "FLV no sequence end mode open\n"); + } else { + /* Add EOS tag */ + for (i = 0; i < s->nb_streams; i++) { + AVCodecParameters *par = s->streams[i]->codecpar; + FLVStreamContext *sc = s->streams[i]->priv_data; + if (par->codec_type == AVMEDIA_TYPE_VIDEO && + (par->codec_id == AV_CODEC_ID_H264 || par->codec_id == AV_CODEC_ID_MPEG4)) + put_avc_eos_tag(pb, sc->last_ts); + } } file_size = avio_tell(pb); @@ -723,6 +728,7 @@ static int flv_write_packet(AVFormatContext *s, AVPacket *pkt) static const AVOption options[] = { { "flvflags", "FLV muxer flags", offsetof(FLVContext, flags), AV_OPT_TYPE_FLAGS, {.i64 = 0}, INT_MIN, INT_MAX, AV_OPT_FLAG_ENCODING_PARAM, "flvflags" }, { "aac_seq_header_detect", "Put AAC sequence header based on stream data", 0, AV_OPT_TYPE_CONST, {.i64 = FLV_AAC_SEQ_HEADER_DETECT}, INT_MIN, INT_MAX, AV_OPT_FLAG_ENCODING_PARAM, "flvflags" }, + { "no_sequence_end", "disable sequence end for FLV", 0, AV_OPT_TYPE_CONST, {.i64 = FLV_NO_SEQUENCE_END}, INT_MIN, INT_MAX, AV_OPT_FLAG_ENCODING_PARAM, "flvflags" }, { NULL }, }; _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
