I'm just wondering how to get the streaming log. Can anybody tell me?

segmenter sample-96k.ts 10 sample_low stream_low.m3u8 ./
[mpegts @ 0xf42180]max_analyze_duration reached
Output #0, mpegts, to 'sample_low':
Stream #0.0: Video: 0×001b, yuv420p, 320×240, q=2-31, 90k tbn, 90k tbc
Stream #0.1: Audio: 0×0003, 48000 Hz, 2 channels, 64 kb/s
[mpegts @ 0xf575f0]stream 0, bit rate is not set, this will cause problems

It keep running without stop. And only one ts file is generated (sample_low-1.ts) and it's getting bigger and bigger. The input file is only 1MB, but the sample_low-1.ts can be more than 5GB (I don't know how big it can be because I have to stop the program). The generated m3u8 file is as follows:
#EXTM3U
#EXT-X-TARGETDURATION:10

What's wrong? Can anybody give an answer?

so far encoding works fine with SVN-r18709 ffmpeg build (strange behaviour with certain builds though). I cannot compile the segmenter.c and I'd be happy if someone could share his successful build. Meanwhile I went with TSMuxer workaround in order to test the whole procedure after all, even though it's a very low standard workaround and involves manual tasks.
As said a build of the segmenter would be highly appreciated. I'm not the best developer around and I really couldn't get this thing compiled (using mingw and dev-cc from bloodshed).
Greetings and thanks for all the knowledge provided on ioncannon! Great work!

So I edited line 242 of segmenter.c and changed guess_format to av_guess_format

Works fine now.

The system works, but I experience a delay of about 15s if I use a 3 chuncks window with each chunck of 1s. I'm working on a LAN so no bandwidth problems. It seems that 8/9 seconds delay are added by ffmpeg before starting the transcoding, while the other 4/5 come from the iPhone caching video.Thanks a lot guys,
Paolo

Did you try various videos? And what was your ffmpeg command. I tried the versions you suggested, but it also doenst work for me on Win 7/Mingw.
