I tried to capture some live streams from ustream.tv using the latest version of Replay Media Catcher 4.3.2. The videos are getting partially unplayable with at least mplayer and vlc, mplayer usually complains about the audio:
[nellymoser @ 013215a0]Packet is too small
lavc_audio: error
Usually vlc can play a few first seconds of the video then crashes. Mplayer freeses but I'm still able to scroll forward through the file. Conversion often fails, when it does not the converted file has nearly the same problems.
Conversion failures are also due to the audio:
Converting - Output #0, mp4, to 'FILE-NAME here':
Converting - Stream #0.0: Video: mpeg4, yuv420p, 640x360 [PAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 90k tbn, 20 tbc
Converting - Stream #0.1: Audio: libfaac, 0 channels, s16, 64 kb/s
Converting - Stream mapping:
Converting - Stream #0.0 -> #0.0
Converting - Stream #0.1 -> #0.1
Converting - Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height
The problem appears with all live streaming videos at Ustream I've ever tried.
You can fetch such videos here: http://www.ustream.tv/discovery/live/all?order=least-popular - any video with some picture and "Live" mark on its icon.
Some channels create slightly different-looking problems, such as this high quality stream: http://www.ustream.tv/channel/hclive13 - I get un-seek-able video, picture freezes, etc., while audio is OK.
I think that's probably a bug in the software. Or may be there are some special settings in RMC that can help to work-around the problem?
