| - | 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). | ||

| - | 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. | ||
