7 minute workout: a straightforward audio recording (and two broken google web sites)

 Last year I had a simple rendition of the 7 minute workout routine recorded by a voice artist.

I wanted a simple audio track to help get the timings right.

 I used to have a good "app" that did it, but that handset died.  Subsequent "app"s have got rubbisher and rubbisher, by having mega-configurable exercise order and making it complicated, with intrusive advertising, by synthesizing unpleasant robot voices instead of simply recording a human voice, and by making everything sound so pumped.

Youtube video mmq5zZfmIws is not bad, but they have not been able to resist having ads, and a quick part of the morning routine can not have ads, it's just too tacky.  But one can watch someone doing each exercise and see how to do it properly.  Incidentally, they are at 30M views, also because daily routine.

 The track I got recorded, in m4a format, is: https://drive.google.com/uc?export=download&id=1c91iH6XJrfCiItTJErJAmIbNdGuHN0tr (direct download link) https://drive.google.com/file/d/1c91iH6XJrfCiItTJErJAmIbNdGuHN0tr/view?usp=sharing (embedded player page).

As well as having the audio file on a device ready to play, it'll be useful on Youtube.  Youtube doesn't accept audio, only video, so I created a blank png image and tried making a "video" with:

    $ ffmpeg -i white.png -i ../r/fitness/7_minute_workout.m4a 7.flv

and this plays fine in video players, but youtube rejected that with "Processing abandoned: The video could not be processed":

so I grabbed a random creative-commons image from the web and added it as background with:

      $ ffmpeg -r 1 -loop 1 -i 51623295501_8abd0e4688_c.jpg -i ../r/fitness/7_minute_workout.m4a -acodec copy -r 1 -shortest -vf scale=1280:720 7.su57.flv

and youtube accepts that: https://youtu.be/Ay5Z2fTcbJk. (Experiment confirms that it's the different ffmpeg command, not the different image, that makes the difference here.  Using the shorter command with the same photo results in the same youtube error).

and meanwhile I'm trying to embed the same video on blogger, but it fails:

 

 

and embedding the output of the second command gives:

 

 

The audio file imports fine into GoPlayer (the Meleshko one) on ios.
