The bmx project has moved to GitHub: - https://github.com/bbc/bmx - https://github.com/bbc/libMXF - https://github.com/bbc/libMXFpp No more development will be done in the Sourceforge git repos. The Sourceforge "General Discussion" forum will remain open for a couple months before it is made read-only. The discussions can now happen in the bmx discussions on GitHub . The existing file releases will be kept on Sourceforge.. The aim is to make future file releases on GitHub. Philip

Hi Philip, Hope you are well ! I'm still alive in BC S/W after 2 take-overs... Hi Sergino, I was the one back then emitting the patch for Avid growing files. I recall that the patch enabled growing OPAtom files for fixed-frame-size essence and was tested back then with AVC-Intra in the then available Media Composer application versions and worked growing Ok. I also had a patch for growing Long GOP/non-fixed-frame-size essence (like XDCAM) that needs regular updating of the Index Tables, but that...

I don't remember the details but one thought is that you may need something like an AAF file to register the clips in Avid. Creating an AAF file for the growing MXF OPAtom files is not something bmx provides. This thread may be of use, https://sourceforge.net/p/bmxlib/discussion/general/thread/23d0e9d3/ Philip

Hi I'm attempting to generate from an MXF OP-1A DNxHD MXF file (8 audio tracks) an OP ATOM clip for AVID media composer in growing mode (that is with enabled the EditWhile Capture) option. Command line is : bmxtranswrap.exe -t avid --avid-gf -o "Avid MediaFiles\MXF\1\testGrow" "Source_20220830_160126.mxf" I found that op atom are correctly created, but media Composer doesn't see them while writing. There is something I missed ?

Fix macro, type definitions for ARM MacOS

Fredrik Lundkvist posted a comment on merge request #4
Ah yes, I had missed that the AAF SDK is publically available and did not double-check, that's my bad. Thank you for letting me know! I'm not quite sure what you are referring to when saying " the name is different", are you referring to the MXF_COMPILER_GCC_ARM_MACOSX macro? As for the type definitions, you are correct; I've pushed a change to fix this error. If you'd like, I could rename the macro and switch __aarch64__ for __arm64__ to align with the SDK as well, though these changes are already...
-
I had a look at the AAF SDK, which is where MXFDump originates from, and it does something different: https://sourceforge.net/p/aaf/code2/ci/a4a578fa0dca53126d0f6925ee11039ec402c9e7/#diff-6 The name is different but more importantly the typedef for mxfUInt32 is "unsigned int" in the AAF SDK change, whereas your change uses "unsigned long int". Based on the other 64-bit definitions I would guess that "unsigned int" is the correct one. Could you confirm whether the definitions in the AAF SDK are correct?...

Support for MPEG-2 576i was only recently contributed to bmx https://sourceforge.net/p/bmxlib/bmx/ci/a96406a18bc936b0a6d711dae134ebdd808195ba/ . Before that bmx only supported D-10 MPEG-2 SD. The support is only for a narrow range of files. The aspect ratio is hard coded to 16:9 and the transfer characteristic is hardcoded to BT.709 (Color Primaries and Matrix coefficients are not set). You can try contacting the contributor to see if they can help you to extend support for MPEG-2 SD. Philip
