I'm not sure if this is a configuration issue or a bug but I am getting the following error during the delivery part of the transcode:

Code: Select all

Getting error code 6  -  The handle is invalid, when trying to deliver "C:\videos\test_video.mxf"

The destination folder exists and is writable by the current user.

Does anyone know what this means and how to resolve it, thanks

Hi Mark, thank you for using FFAStrans and welcome to the forum!

First, does this happen with all files? Also, can you please try some other destination, preferably on other drives or maybe a network share? You can also try an momentarily turn off your antivirus to see if it has any effect.

I had been searching for a transcoding solution like this and had been looking at tools by Adobe, Sorrenson, Main Concept and Imagine.
I ended up building a system around Adobe Media Encoder. I didn't find this tool until I was searching to see if it was possible to use ffmpeg as part of an input chain for Adobe Media Encoder.

The error occurs on all input files. I've tried different destinations. Even deleted the delivery processor and added it back to the chain.
I tried a network folder and still encounter the problem.

I've also tried to use an FTP deliveries processor and got the message "could not set the destination directory to" I was able to see on the ftp server that despite the ftp processor configuration path beginning with / (root directory) the ftp processor was appending the path to the login directory.
Once I resolved the path issue. FFAStrans monitor says success but no file is written to the ftp server. The FTP server sees the connect and the change directory and then the network connection is terminated.

Is there a debug log for FFAStrans?

I've discovered the problem is that the source file name in the "ticket".ini file has an additional .mxf extension.

eg;

Code: Select all

 Source="c:\.ffastrans_work_root\20160922150016\20160923-141227-754-F83411174C47\~20160923-141237-272-3D5DDC050CB1.mxf.mxf"

but the file on disk only has 1 .mxf extension.

I started processor manually with an edited ticket ini and the file was delivered successfully.

I've found an entry in the log that appears to be creating a file with the additional extension, but I cannot see the output file on disk.

I don't appear to have the bmxtranswrap.exe on my machine. I only have MXFDump.exe and raw2bmx.exe in the mxf_tools directory. I cannot find bmxtranswrap anywhere in the FFAStrans0.7.6 directory tree.

I downloaded and copied the binary in there manually, but I don't know if it's the correct binary as I'm getting a different error now and delivery of a 19k MXF file.

Any help would be appreciated.

Hi Mark,

Don't pay attention to the double .mxf's. It's not an error and it's not related to your problem. What's more worrying is that i forgot to distribute the bmxtranswrap tool

Sorry about that!
The binary you downloaded is probably just fine.

Can you please send me your workflow so I can investigate? Also, if it's possible for you to share with me a short sample of the media you're trying to convert. If not then that's fine but I would at least like to know the media properties.

The source files are nothing special, the majority are simply H264/AAC/MP4. I have encountered some files which are causing encoding problems, but I'll raise this in a different post after we get XDCAM output working.
We tried different output processors (h264/aac/mp4, DNxHD/MXF and XDCAM/MOV) without issue.

I built the simplest workflow I could, for testing source and compatibility with our playout system.
Folder -> AV/Media -> XDCAM -> Folder

this is the command I see is running;

Code: Select all

C:\WINDOWS\system32\cmd.exe /c ""C:\Users\mheath\Downloads\FFAStrans0.7.6_Win32\Processors\mxf_tools\bmxtranswrap.exe" -o "c:\.ffastrans_work_root\20160922150016\20160923-172741-495-70B7DB8CB4F1\~20160923-172744-902-958CA338DC54.mxf.mxf" "c:\.ffastrans_work_root\20160922150016\20160923-172741-495-70B7DB8CB4F1\~20160923-172744-902-958CA338DC54.mxf"

bmxtranswrap defaults to type as02 (I thought we want op1a) as02 produces a directory (which it calls a bundle) with the double .mxf extension containing demuxed mxf streams. This does not look right to me.

section from bmxtranswrap help

Code: Select all

  -t <type>               Clip type: as02, as11op1a, as11d10, op1a, avid, d10, wave. Default is as02
* -o <name>               as02: <name> is a bundle name
                          as11op1a/as11d10/op1a/d10/wave: <name> is a filename
                          avid: <name> is a filename prefix

which is producing, the bundle

I would expect these files to be remux-ed back together but instead it just appears to try and copy the directory.
I now get the error

I got a bit fooled when I saw the error code 3 and manually aborted the job. I can see that the correct file does eventually appear, but it's named incorrectly and other files are also delivered. It doesn't appear to be working as expected.

I've just checked the resulting file and it has no audio.

I'm very sorry you're have problems with this but the way you describe the behavior is far from what I'm seeing in my setup. Now, maybe your build of bmxtranswrap.exe is very different from mine so I'm posting the same version I've been testing with. Also, I need to know your "XDCAM-HD"-node configuration.

Thanks for reporting your issues!

That version of bmxtranswrap is much newer than the version I had downloaded. Although I thought I had downloaded it from the official site it was dated 2012 so I thought it hadn't been updated in ages.

This has resolved the MXF transcoding problems.

Thanks for responding so quickly.
