Summary of the bug:
I am trying to transcode swf to mpegts format,But I failed.
Use the tool to analysis SWF file:
<?xml version="1.0" encoding="utf-8"?>
<SWF type="CWS" Version="9" FileLength="257819" width="640" height="480"
FrameRate="18" FrameCount="270">
<tags count="302">
<FileAttributes class="zero.swf.tagBodys.FileAttributes"
UseGPU="false" UseDirectBlit="false" HasMetadata="false"
ActionScript3="false" suppressCrossDomainCaching="false"
swfRelativeUrls="false" UseNetwork="true" rest="0x00000000"/>
<block swfSrc="aa.swf" offset="27" length="257792"/>
</tags>
</SWF>
,It says the file have 270 frames,buf FFmpeg only decoded one Frame
