Thanks Barough,

Is there a 'change log' for this version?

With GPAC versions is a little mess. Currently there is version 7.2.0 already. I don't know what GPAC contains, who is interested in this.

I pinch what the users forced on the creators.

Hi all,

Out of interest, are there any new MP4box muxing UI's that offer support for muxing HEVC in .mp4?


Cheers

[stax76]

staxrip can be used as muxing UI as it supports stream copy.

New function for image HEIF(Apple):
https://gpac.wp.imt.fr/2017/06/09/gp...port-for-heif/

MP4Box -add-image file.hvc:primary -ab heic -new image.heic
MP4Box -add-image file.hvc:time=1.2:primary -ab heix -new image.heic
MP4Box -add-image tiled.hvc:split_tiles:primary -ab heic -new tiled.heic

Dumping Options
 -dump-cover          Extracts cover art
 -dump-item args      dumps item to file - syntax item_ID[:tk=ID][:path=fileName] (What is with dump-image???)


Importing Options

File importing syntax:
":xps_inband"        Sets xPS inband for AVC/H264 and HEVC (for reverse operation, re-import from raw media)
 ":max_lid=N"         sets HEVC max layer ID to be imported to N. Default imports all.
 ":max_tid=N"         sets HEVC max temporal ID to be imported to N. Default imports all.
 ":tiles"             adds HEVC tiles signaling and NALU maps without splitting the tiles into different tile tracks.
 ":split_tiles"       splits HEVC tiles into different tile tracks, one tile (or all tiles of one slice) per track.

                        tk=ID:            meta location (file, moov, track)

Very interesting, there was no "lack of time" for adding HEVC support to MP4Box...

Seven years later, jeanlf finally confirmed he and his team don't care at all:

TrueHD support has been added recently...does anyone have test it ?

[SeeMoreDigital]

If somebody creates some muxes, I'm happy to test them with my hardware playback devices...

[filler56789]

MP4Box - GPAC version 1.0.1-rev0-gd8538e8a-master

now requires the av* and sw* libraries...

So why not just use ffmpeg instead of mp4box?

Just tried it, did not work, MP4Box did freeze/hang.

By the way.....
this thread was started on 23rd May 2005, 16:55 UTC...
maybe it should be locked for good, since nothing important has happened to GPAC after the HEVC support was added to it.

[Kurtnoise]

obvioulsy, you know nothing...so, please go away.

[manolito]

I know this is a little bit OT, but since some MP4 gurus are here I figured that I can ask a question about the MP4 container here...

I do not like the Apple world, so my favorite container is MKV. But sometimes I get a request from a friend to repack the file I sent him into an MP4 container because his player(s) do not like MKV.

Of course I can do this, and the resulting MP4 plays fine. But what I do not understand is why this resulting MP4 has a Variable Frame Rate when the source had a Constant Frame Rate.

My original source is an FLV file with AVC video and AAC audio at a CFR of 29.97 fps. Repacking it to MKV always keeps the CFR. But when I use either FFmpeg or MP4Box to repack it into an MP4 container I get a file with VFR.

Frame rate mode : Variable
Frame rate : 29.970 FPS
Minimum frame rate : 29.412 FPS
Maximum frame rate : 30.303 FPS

Only the latest AviDemux repacks it into a CFR Mp4 file. An older AviDemux version which I need to use under WinXP has a choice of 2 different MP4 muxers, and one of them creates CFR and the other one VFR files. Quite confusing...

Can anyone shed some light on why FFmpeg and MP4Box need to create VFR MP4 files when the source clearly was CFR?
