flv_write_packet实现

[wxl-liam]

flv_write_packet里
if (par->codec_id == AV_CODEC_ID_VP6F || par->codec_id == AV_CODEC_ID_VP6A ||
par->codec_id == AV_CODEC_ID_VP6 || par->codec_id == AV_CODEC_ID_AAC ||
par->codec_id == AV_CODEC_ID_OPUS)
flags_size = 2;
else if (par->codec_id == AV_CODEC_ID_H264 || par->codec_id == AV_CODEC_ID_MPEG4 ||
par->codec_id == AV_CODEC_ID_H265 || par->codec_id == AV_CODEC_ID_VP8 ||
par->codec_id == AV_CODEC_ID_VP9) {
if (is_flv_extern_header_enable(flv, par->codec_id) && (pkt->dts != pkt->pts)) {
flags_size = 8;
} else {
flags_size = 5;
}
}
else
flags_size = 1;

如果是扩展rtmp头，flags_size是8为什么不是5
