I believe what is happening is that sometimes a segment will only contain audio, and even if the next segment contains video it will end up confusing at least ffmpeg based players since it seems to rely on scanning the first few FLV tags to see what it contains. I believe this may cause the end of the output file to get truncated when the stream ends since it exits before the file is fully written. It appears that when this stops, the file gets written to. I can't find the command line string for RTMPDump.Īlso, not sure if this is normal, but the "Written" size increases fast for a short time, then stops for some time. Funny thing is, I was using RTMPDump and RTMPSuck for awhile, but Usteam must have changed something recently since RMTPSuck won't work on it anymore but livestreamer does, to a point. I was outputting to a file, not to VLC directly. I need to do some more testing to see if this is a time dependent thing, I know it happened as soon as I started livestreamer one time, but not usually. Unfortunately there is no way for you to fix this. VLC does not support the audio or video format "undf". I would then get the following error when I tried to play it with VLC: The URL it lists is not a valid URL, not sure where it got it from. Failed to open chunk 1395191177: Unable to open URL: /sjc-uhs23/streams/httpflv/ustreamVideo/952665/stream But after maybe 45 minutes, it gave me the following errors (same error several times): I tried this with the build "livestreamer-v1.7.5-65-g752eaaa-win32.zip" and it appeared to work ok for awhile.
