-Chris Duxbury has worked out a simple syntax we can use to extract our .ts files to .mp4 files (.mp4 is a valid container for both h.264 and HEVC steams).

-==== FFMEPG ====
-The following syntax will work for SPTS files (not sure about MPTS)
-\\
-   ffmpeg -probesize 50000000 -i source.ts -map 0:0 -map 0:1 -map 0:2 -c copy destination.mp4
-\\
-The <color red>probesize</color> bit tells ffmpeg to look over lots of file for the I picture, otherwise on long GOP it seems to give up sometimes. (like most decoders, ffmpeg can't start to decode until it finds an I frame)
-\\
-\\
-Using <color red>-map 0:0 -map 0:1 -map 0:1 -map 0:2</color> tells ffmpeg to select/map specified input streams to output in that order.
-\\
-\\
-Using <color red>-c copy</color> mark all the streams to be just copied to the output
-\\
-\\
-==== FFPLAY ====
-FFPLAY comes bundled with the ffmpeg download. The ffplay is a simple to use command line app for playing the extracted streams that you have just created.
-\\
-\\
-The simple use of fflplay is just:
-\\
-    ffplay filename.mp4
-\\
-However, the issue with UHD streams is that they are larger than most monitors, so it is generally necessary to either rescale the output, or force it to fullscreen.
-\\
-\\
-To replay a video in a window.
-\\
-    ffplay -i video.mpg -vf scale=800x600
-    This will replay the selected file at a window size of 800x600. Remember, currently (End 2016)
-    UHD streams play very poorly and you will only get 1 or 2 frames per second.
-\\
-To replay a video full screen.
-\\
-    ffplay -i video.mpg -vs
-    This will replay the video at fullscreen resolution.
-\\
-\\
-==== FFPROBE ====
-FFPROBE allows the inspection of a file for some basic information. ffprobe is useful to analyse a .ts file before extraction to see what streams are present, the PIDs etc.
-\\
-    ffproble filename.ts
-    Input #0, mpegts, from 'AVP4000_HEVC_SDR.ts':
-      Duration: 00:01:01.45, start: 63552.709811, bitrate: 24918 kb/s
-      Program 1
-        Metadata:
-          service_name    : AVPUHD
-          service_provider: Ericsson
-        Stream #0:0[0x3e9]: Video: hevc (Main 10) ([36][0][0][0] / 0x0024), yuv420p1
-le(tv, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 50 tbc
-        Stream #0:1[0x7d1](eng): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 192 kb/s
-\\
-\\
-In the above example we can see the following:
-\\
-\\
-Duration: 00:01:01.45, start: 63552.709811, bitrate: 24918 kb/s
-The <color red>Program 1</color>
-\\
-The <color red>service_name</color> is AVPUHD
-\\
-The <color red>service_provider</color> is Ericsson
-\\
-The <color red>Stream #0:0[0x3e9]</color> <color red>0x3E9 is Dec 1001</color> is <color red>Video: hevc (Main 10) ([36][0][0][0] / 0x0024), yuv420p1</color>
-\\
-The <color red>Stream #0:1[0x7d1](eng)</color> <color red>0x7d1 is Dec 2001</color> is Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 192 kb/s.
