I'm at work now so I'll try when I get home (you know, it's 10am here :-)) and post some log digest here. Thanks for all your input! There's a lot of main warning: late buffer for mux input (45611) main warning: PTS is out of range (-29722), dropping buffer main warning: output date isn't PTS date,...

30 to 70% shouldn't be an issue. Did you note the memory in use IE. was there any memory left to use? Did Messages indicate a problem during the transcode? I do MPEG2 to MP4 quite often and don't experience a problem even for real time encoding. I suspect that there are some high bandwidth/fast mot...

The only thing I can think of is your machine may be to slow to capture a live stream and watch it too. Normally in a transcode the coding will speed up or slow down according to the speed of the machine, resolution of the video and or bit rate. Try opening your task Manager and look at the CPU usa...

Also it is seldom that MPEG 2 is 25fps generally it is 29.97 or has a 3-2 pull down applied so that it would be 23.976 Sure, when it's DVDs and the like, but this is IPTV that my ISP transcodes (maybe even sends raw?) from DVB-T or DVB-S, and this comes in my country's format, which is PAL, i.e. 25...

Just remuxing with MP4Box is not going to resolve the issue as MPEG2 video needs to be transcoded into MP4 before muxing in MP4Box. If you want to do this in VLC you will need to add the command mentioned earlier. Ha, I'm not in sync with you in sending messages ;-) I tried to remux the recorded mp...

From MPEG2 to MPEG4 you will need the command fps=<framerate> Do you mean, that the file can be corrupt because I'm missing fps from the commandline? Should I then record using e.g. --sout-transcode-fps 25.0000 :sout=#transcode{vcodec=mp4v,vb=4096,scale=1,acodec=mp4a,ab=192,channels=2}:duplicate{ds...

I bet the transcode fell behind the stream at some point and the output file got mucked up. Can't you use a 2-stage process, saving first to file as an MPEG TS encapsulation with no video or audio transcoding and run the transcode to mp4 after? Well, the IPTV stream is somewhere between 8 and 16 Mb...

What's the source format and container? As I said, I'm grabbing IPTV (udp://@239.255.11.116 :udp-caching=600), I think that it's mp2v/mpga in a MPG TS..... Just checked the log, it's "TS over raw UDP", mpga, mpgv, libmpeg2 decoder, mpeg_audio debug: MPGA channels:2 samplerate:48000 bitrat...

I retried with enforced mp4 demuxer (on another file, but same problem...). I noticed that in my previous post, the log would not be complete (up to the "main: nothing to play" message), instead VLC would eat CPU until manually aborted with "Stop", after which it would continue w...

Hi, I'm using VLC 0.8.6 on W2k to grab IPTV to mp4 using something like this: udp://@239.255.11.116 :udp-caching=600 :sout=#transcode{vcodec=mp4v,vb=4096,scale=1,acodec=mp4a,ab=192,channels=2}:duplicate{dst=display,dst=std{access=file,mux=mp4,dst="D:\Videos\test.mp4"}} The problem is that ...
