The demo video doesn't seem to have any audio in it! At least none that either ffmpeg or whatever Firefox uses can recognize.

- huseyinkeles 1y agoI can hear it on safari
- Daunk 1y agoSame on my end, no audio in the video.
- jamilton 1y agoSame here, but it worked when I opened it in Chrome. What a weird error - you would think that playing an embedded mp4 with audio wouldn't differ from browser to browser.
- mnmalst 1y agoI was surprised by this as well at first but thinking about it, it would make sense when they use an audio codec which is not supported on the target system. In that case the video can still play but the audio can't. I wasn't aware tho that audio can be disabled separately.
- ertian 1y agoYeah, I've run a local Kokoro instance, and it doesn't work with Firefox. This uses Kokoro under the hood.
- noisem4ker 1y agoThe demo clip is static and has the Kokoro output encoded as the audio track. It's not Kokoro running and generating it in your browser in real time.
- noisem4ker 1y agoIt's probably due to the unusual sound format, 24kHz mono PCM, and the fact that it was somehow forced into a WebM container, which only supports Vorbis and Opus officially. It looks like the author created it using the "higher quality" ffmpeg command line, except for the "webm" final extension, producing the opposite of what's described as "an MP4 file that's compatible with more devices". https://github.com/denizsafak/abogen/tree/main/demo#for-higher-quality-but-larger-video-mp4 https://github.com/denizsafak/abogen/tree/main/demo#for-high...
- frumiousirc 1y agoThanks for this. I thought I had some local issue with waterfox. Pasting the (long) video URL to the terminal let's mpv play it with audio.
