IMX D10 File Encoding Fails to Produce Valid IMX File

[Steve]

After moving from v1.0.8 to v2.1.1, encoding a file to Quicktime IMX format no longer works.

Produces an output file that plays but the VBI area is visible and it is not recognised as an IMX file. Just a quicktime file with mpeg2video as the video codec.

Encoded attempted with ffmpeg 2.1.1 from FreeBSD ports

[Carl Eugen Hoyos]

Replying to steven:

Encoded attempted with ffmpeg 2.1.1 from FreeBSD ports

Is the problem also reproducible with current FFmpeg git head?

How can I reproduce that the encoded file is bad?

[Carl Eugen Hoyos]

Please test these two versions (I suspect I have found the offending commit, but I don't know how to test):
e4d45673 and 713dcdbf

[Carl Eugen Hoyos]

Please test if attached patch from Michael fixes the issue for you.

[Steve]

Forgive my ignorance but do you know if the current githead + patch will compile without modification on FreeBSD? If not what is the best linux distro to use? I'll spin up a VM with it and test on there.

Thanks

If not that would be an important bug that we would (very much!) like to know about.

Just in case you don't know: The preferred way of compilation is $ ./configure && make ffmpeg, you don't have to install to test (I absolutely never install) and you should really install yasm 1.2, it is a standalone binary. (You of course need a working C compiler and GNU make.)

[Carl Eugen Hoyos]

Any news on this?
I don't know how to test this issue (can I test it easily?), so if you want this fixed, please test the suggested versions (to confirm the issue) and the attached patch.

[Carl Eugen Hoyos]

I can confirm that this is a regression since e4d45673 and that attached patch by Michael fixes the issue.

[Carl Eugen Hoyos]
