Podcast to YouTube: ffmpeg One Liner Scripts

Here are some examples of how to convert audio podcasts in mp3 format to YouTube videos in mp4 format adding nice black and white wave form visualisations. They require the ffmpeg command-line tool, and are one-liners that must be run from the Windows command prompt.

NB/ I used these one-liner scripts to convert Roy’s Rocket Radio to YouTube-able vids. That was the easy part. The agonizingly slow part was uploading to YouTube.

One File
ffmpeg -i YOURFILE.mp3 -filter_complex "[0:a]showwaves=s=640x480:mode=line:rate=25,format=yuv420p[v]" -map "[v]" -map 0:a YOURFILE.mp4
Replace YOURFILE with the file you want to convert.

All Files in a Directory
FOR /F "tokens=*" %G IN ('dir /b *.mp3') DO ffmpeg -i "%G" -filter_complex "[0:a]showwaves=s=640x480:mode=line:rate=25,format=yuv420p[v]" -map "[v]" -map 0:a "%~nG.mp4"

Roy's Rocket Radio's Doctor Who Divali/Halloween Weekend 2016!

doctor-who-the-space-pirates-1969I intend watching a whole lot of Who this weekend. Specifically the last two adventures of the Doctor, as portrayed by Patrick Troughton.

So if you find yourself bloated by one too doctor-who-the-war-games-1969many laddu this Divali Sunday, or chomped on the entire bowl of sweets on Halloween Monday, take a trip through time and space with me, with your geeky host (who is certainly NOT “The Captain!“), back to 1969 to enjoy Doctor Who in The Space Pirates and The War Games.

Let’s send the second Doctor off in style.

Here’s more Old Who than you can brandish a Dalek’s gunstick at! (I know, I know, that was rather hackneyed, but I’ve been doing this for a while and the good material’s getting harder to come by). And even more Doctor Who (New Who, Old Who, and just plain weird Who)!

Nintendo Switch (NX)

Finally! All hail the arrival of the Nintendo Switch (AKA NX) with this ad clearly aimed at an aspirational, sophisticated and older (but not too old) audience or, more likely, those who want to be like that. Still, almost 5 million YouTube views in 12 hours can’t be bad. Besides, that ad even has me up at 03:45 in the morning writing this, so it must have made an impression… and it has.

In essence, it’s a tablet device, with detachable controllers, that can also be transformed into a console by sticking it into a docking station. So, plenty of flexibility and options.

From a techno-geek’s point of view, I think it’s great because it looks like Nintendo have pulled out all the stops and bundled all their previous technology into one modular device. If not exactly groundbreaking, for a company like Nintendo, it does seem technically innovative.

Online tech sites guesstimate the price to be around £300 (GBP300-USD350). So it’s not Wii cheap; more along lines of the current PS4 and a tad more than the Xbox One or its unsuccessful predecessor the Wii U.

Reservations? Well, the price, but those controllers too. Either joined to form one big separate controller, attached to the tablet or detached completely, they look clunky and I also wonder how firmly they’ll click into place in each of those configurations. Also, when completely detached, to be used as mini-controllers, they look teeny-tiny with sharp corners. Perhaps comfort and ergonomics might be an issue?

As for ecosystem, most sites are reporting the same range available upon release, so I’m just regurgitating that list here: The Legend of Zelda, The Elder Scrolls 5: Skyrim, Mario Kart, a new NBA game, a new Super Mario game and Splatoon.

Have a great morning and if you want more of this stuff, be sure to subscribe to my podcast Roy’s Rocket Radio.
