Long duration hevc file not muxing #25

Open Learner00100 opened 2 years ago

Learner00100 commented 2 years ago

Hevc file with long duration like 1hr or more not muxing and output file is 0bytes and mp4muxer.exe running where read disk activity occur for few seconds but no write disk activity. For hevc clips like 2min duration it works fine. Kindly solve the error, thanks.

The purpose of dlb_mp4base is to help Dolby's customers/partners to implement theirs mux tool, not use the tool directly. The executable tool provided is just for testing purpose, so it has limited quality. We recommend to use Bento4 which Dolby has finished the contribution, and make it support Dolby codec.

Thanks for information, is bento4 support dlb_mp4demux also? Is mp4extract in bento4 is same as dlb_mp4demux?

You can use dlb_mp4demux for ac3, ec3 and ac4 demuxing.

@Learner00100

Have you fix this problem already?

I was using this command:

mp4muxer --dv-profile 5 -i video.hevc -i audio.ec3 --media-lang eng -o outputfile.mp4

Do you know something similar and what command should i use?

Bento4 has mp42aac, mp42avc, mp42hevc, that's all codecs they've supported.
