I have the exact same issue. File can be played fine when I skip the audio track, otherwise players don't recognize dvhe audio codec.
Any update on this? Is there something wrong with my command? An mp4 muxer that doesn't mux audio correctly is fairly useless.
Have you got any chance to test the latest binary?
Didn't have notifications configured properly so didn't notice there was a new binary. I will try with my files when I get home tonight.
As far as I am able to tell the latest binary fixes the issue for me. The Codec ID field in MediaInfo now shows ec-3 instead of dvhe and my player recognizes the file and plays it back.
New build fixed the issue, thanks!
When using this test file:
http://media.developer.dolby.com/DolbyVision_Atmos/mp4/iOS_P5_GlassBlowing2_3840x2160%4059.94fps_15200kbps.mp4
The untouched file's metadata is:
Stream #0:0[0x1](und): Video: hevc (Main 10) (dvh1 / 0x31687664), yuv420p10le(pc), 3840x2160 [SAR 1:1 DAR 16:9], 15184 kb/s, 59.94 fps, 59.94 tbr, 60k tbn (default)
Stream #0:1[0x2](und): Audio: eac3 (ec-3 / 0x332D6365), 48000 Hz, 5.1(side), fltp, 640 kb/s (default)
My mp4muxer command:
mp4muxer -o output.mp4 -i input.hevc -i input.ec3 --dv-profile 5
After using ffmpeg or mp4demuxer to demux and mp4muxer to remux:
Stream #0:0[0x1](und): Video: hevc (Main 10) (dvhe / 0x65687664), yuv420p10le(pc), 3840x2160 [SAR 1:1 DAR 16:9], 15185 kb/s, 59.94 fps, 59.94 tbr, 60k tbn (default)
Stream #0:1[0x2](und): Audio: none (dvhe / 0x65687664), 48000 Hz, 5.1(side), 640 kb/s (default)
The resulting file after using mp4muxer has audio that is unplayable because of the incorrect header.
