How to convert to hap

[smtabatabaie]

Hi , thanks for this add-on. I could run it with sample videos from renderheads website. I have worked with Hap videos and could convert Hap .mov videos using Quicktime. But I don't get how you can convert Hap videos in avi format and use them in this add-on. I'll appreciate if you can help me with this.

i'm sorry i never responded to this.

did you install the codec from renderheads? http://www.renderheads.com/downloads/2015/HapDirectShowCodecSetup.exe

this addon plays back .avi files, so the .mov files you created won't work. i'd start with the original uncompressed files and export them using after effects or media encoder. if you don't use adobe software, ffmpeg should do the trick.

Hello.

Thanks a ton for this addon. I'm starting to use it more and more.

Like smtabatabaie, I'm also trying to convert files to a format compatible with the add-on. I'm using ffmpeg. I'm not using Adobe CC because I need to script the conversion.

The ffmpeg-converted video plays back. However, it gets yellow lines probably identical to those mentioned in this thread: https://forum.openframeworks.cc/t/ofxdshapvideoplayer-windows/21237/15

I'm able to play back the video using libavcodec and libavformat via the ofxAvCodec addon.

Here's a link to the problematic video: https://drive.google.com/file/d/0B9FJuRHqB9n-aGZ1VjNocDdEYVE/view?usp=sharing

Here's the ffmpeg command I'm using to create the video: ffmpeg -i fingers.mov -vcodec hap fingersHap.avi

Any suggestions on how to get encoding via ffmpeg working?

Thanks!

After digging a bit deeper, Windows Media Player will play the provided sampleDirectShow.avi but when playing back my troubleshow file the screen is black. So it must be user error when encoding. Am I missing something?

hi corey, i'm on the road for work rn. so it might be a few weeks until i can dig into this. apologies for that.

what codec is your original file? that could play a role as well.

I get this a lot with this add on, think it’s to do with colour space of the original file but not 100% sure.

Here's the output of ffprobe. I'm testing on the fingers.mov file that ships with the openFrameworks videoPlayer example:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'fingers.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt creation_time : 2015-09-09T17:14:13.000000Z Duration: 00:00:07.28, start: 0.000000, bitrate: 650 kb/s Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, smpte170m/smpte170m/bt709), 320x240, 645 kb/s, 30.10 fps, 30 tbr, 1k tbn, 2k tbc (default) Metadata: creation_time : 2015-09-09T17:14:13.000000Z handler_name : Apple Alias Data Handler encoder : H.264

Could be. Again, Windows Media Player won't play it back either. But I can get it to play back using libavcodec and libavformat. I can post that code if it's helpful. I think it converts the color space as part of the SwsContext image scalar part. Hmm. I'm also out for a bit but might have time to step through the code to see what it's doing to the color space, and if that process translates into ffmpeg command-line args.
