[SOLVED] Easiest way to join MP4 files from streaming site?

[yetanotherlogin]

Hello

I used wget to download the hundreds of parts that combine to make up a 1hr50mn streamed file:

Input #0, mpegts, from 'file.0.ts':
  Duration: 00:00:09.60, start: 10.000000, bitrate: 2130 kb/s
  Program 1
    Stream #0:0[0x102]: Unknown: none (ID3  / 0x20334449)
    Stream #0:1[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv,bt709), 1280x720 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc
    Stream #0:2[0x101]: Audio: aac ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 195 kb/s

Unsupported codec with id 0 for input stream 0

To join/convert the parts into a single file, I tried the following, but ffmpeg isn't happy:

ffmpeg -f concat -i input.txt -c:v libx264 -vf scale=640:-1 -pix_fmt yuv420p -c:a aac -strict experimental -b:a 128k -ac 2 -ar 44100 -threads 2 -crf 20 -f mp4 output.mp4
…
start time for stream 0 is not set in estimate_timings_from_pts
DTS -830103474725263616, next:9600000 st:1 invalid dropping
PTS -830103474725260032, next:9600000 invalid dropping st:1
DTS -830103474725261696, next:9621333 st:2 invalid dropping
PTS -830103474725261696, next:9621333 invalid dropping st:2
etc.

Any idea why? Is there another free tool for Windows that would work?

Thank you.

Edit: DOS did the job allright, provided the filenames sort correctly:

copy /b *.ts full.mpeg
