I'm testing rtmpdump-20140302-git-79459a2-win32.7z with rtumpdumphelper v1.21 by http://www.nirsoft.net to download video from http://www.kuke.com in my XP SP3. The download is smooth, but every video captured so far has problem playback. For example in http://www.kuke.com/#t=v/kuke/video/play?cataid=GI-11, the generated command is
During the playback via mplayer2 2.0-701-gd4c5b7f-2ubuntu2 with OSD timer turned on, the first 5:05 is OK, then it starts incomprehensive stammering audio, and video is still smoothly played until around 15:00. During meanwhile, mplayer raises continues "Too many video packets in the buffer: (4096 in XXXXXXXX bytes)" You can see the A: is gradually lagging further and further behind the V: in the command prompt. Then at 15:02 video is frozen and audio resumes to normal for a few minutes with frozen "A: 718.6 V: 902.9 A-V:-184.315" prompted on command line. Finally, at around 15:04 all audio and video playback resumes to normal for the last 2 minutes. The other videos have similar problem - only the first few minutes is OK. Another possible related problem is any seek operation will generally make the audio video out of sync immediately. I've tried other players too, say VLC-2.1.5 in Windows and avplay-9.16-6:9.16-0ubuntu0.14.04.1, all have problem play the captured. All the videos tested can be smoothly played from the site via browser flash plugins, so the source shouldn't be a problem.
