macOS compile

[grylem]

Is this possible compile on macOS?

[wangf1978]

grylem,

Thanks for your attention and comments, I am very glad this project is noticed by somebody, sweet!

I am not familiar with macOS development environment, but I am familiar at Linux development environment, I planned to let it to be compiled well under Linux after finishing MMT/TLV elementary stream extracting this month, and then macOS, it may not take too much effort for me to finish it.

BTW:
Of course, if anybody is interested in this open project, it is welcome to add this kind of platform porting, it may be more efficient, :)

possible if the project can be compiled under Linux it can be compiled under macOS.
this can be checked when you finish your work for Linux porting.
good luck

[wangf1978]

Now it can be compiled successfully under linux, please see the details in the README.md

[grylem]

Tried to compile under macOS but not successfully. Too many errors. some managed to solve - by adding to makefile -std=c++14, some not yet

[wangf1978]

Fix it, please see the details in README.md
It works well under macOS Mojave although there are still some warnings to be fixed

Thanks.
DumpTS test.mp4 --showinfo --removebox='udta'
show same info like DumpTS test.mp4 --showinfo and mesage

[wangf1978]

Sorry for unfriendly usage, at present it does NOT support in-place removebox.
You can use the below command:

DumpTS test.mp4 --showinfo
DumpTS test.mp4 --removebox='udta' --output=test_new.mp4 --verbose=1
DumpTS test_new.mp4 --showinfo

In-place removebox will be supported later.

[grylem]

Thanks!
Please remove this example from readme
DumpTS C:\test.mp4 --showinfo --removebox='unkn'

[wangf1978]

Thanks, after checking the code, these command can be supported, but there are some bugs in MacOS, and in Windows/Linux, there also exists a issue, I will fix them together soon.

This issue is already fixed, too.

[wangf1978]

Many thanks.
Fixed it in the latest commit.

[grylem]

Thanks.
Can you test this ..?
there are two files
test.mp4 from final cut
test1.mp4 other source
DumpTS test.mp4 --removebox='udta' - processed file is broken
message from terminal -
removebox : udta
input : test.mp4
[Box][sdtp] Can't find 'stsz' or 'stz2' box to get sample count.
DumpTS test1.mp4 --removebox='free' - processed file is broken
removebox : free
input : test1.mp4

in both cases no vidio and audion in processed files.

[wangf1978]

can you upload test.mp4 and test1.mp4?
I have tried the file t.mp4 in my side, it seems to work well.

[grylem]

of course
for your 1.mp4 all ok.
orig.zip
processed.zip

[wangf1978]

Thanks for your materials, it is fixed, please check the latest commit.

[grylem]

tested in another way
./DumpTS test.mp4 --output=test.h264 --trackid=2 --outputfmt=es
[Box][sdtp] Can't find 'stsz' or 'stz2' box to get sample count.
that's not all
extract *.h264 with other diffirent soft
rhash test.h264 test_1.h264 test_2h.264
for extracted with DumpTS checksun is b27b46ef31bd9d41b91b2e593aff50b7
for other 2 files 1dc1d4576ed0d4fefa023e70f88d3bb1
compare in hex fiend test.h264 and test_2.h264
has 505 differences in one byte

[wangf1978]

H.264 SPS/PPS is added at the beginning?

[grylem]

You can make own test. test.mp4 from orig.zip

[wangf1978]

Ok, thanks.
can you upload the dumped .h264 stream with other software?
I will do binary comparing, and something should be found.

[grylem]

you can do it yourself
https://github.com/DolbyLaboratories/dlb_mp4demux
https://github.com/gpac/gpac for gpac you need an old version v5.2
or you can use other programs that you like.and compare the result
