I downloaded 3 videos at once using your add on. the biggest one being 13gb in all.Problem is even with FFmpeg installed it only muxed ONE of the three videos and now I have 2 extremely large video and audio files on my pc that won't play in anything.Is there any way to access the muxing utility in your add on? I've tried using other programs to mux the video and audio but none work and most of them are just glorified converters not real muxing utilities


Other than that I do like your add on and think its a very good product. If I can get it going right its gonna help me tremendously in getting 1080 material from youtube

This review is for a previous version of the add-on (5.0.7.1-signed).

Thanks a lot for your appreciation. Interesting problem you are having there!

CYS has been tested for concurrent downloads/muxing, but never for files of this size, admittedly. We will look into this issue (please send us the link to that video). Until then, yes, you can always perform the muxing step manually, provided that you have downloaded both the video and audio entirely (otherwise either track will be truncated).

BTW, we wholeheartedly recommend Media Player Classic Home Cinema (http://mpc-hc.org) as the best all around free, open-source media player for Windows. MPCHC is smart enough to play the raw DASH video/audio tracks you saved. Newer versions of MPC should also do this on all platforms.

To mux audio+video, follow these steps:
- ensure that the FFmpeg executable is either in your system PATH, or temporarily, copy the executable into the folder the audio and video to mux are
- open a console window (terminal on Linux/Mac), and step into the folder with the audio and video to mux
- use the following command replacing *vtrack* with the name of the video track file, and *atrack* with the name of the audio track file:
ffmpeg(.exe) -i *vtrack* -vcodec copy -i *atrack* -acodec copy muxed_video_file.mp4

Make sure you give the resulting file ("muxed_video_file" here) a name that is different from the name of the video track file, ffmpeg will refuse to do the muxing if they are the same.

We hope this solves you problem. Thanks a lot for your fairness!
