Error: MD5 file is not small

[wlowry]

Hello,

I've attempted to convert a DPX sequence of 17,739 images to MKV with an MD5 manifest as an attachement but am getting the following error: Analyzing files (99.97%), 2 files/s Error: WIF_120_D1A35/WIF_120_D1A35_file_checksum_manifest.md5 is not small, expected to be an attachment?
Please contact info@mediaarea.net if you want support of such file.
Track 1:
.wav
WAV/PCM/48kHz/24bit/2ch/S/LE
Track 2:
_%06d.dpx
(000000 --> 017738)
DPX/Raw/RGB/12bit/U/LE/FilledA

The MD5 manifest is a list of checksums for the DPX file (not framemd5) and is about 1.3MB.
I've successfully encoded sequences with smaller image numbers (and smaller MD5 manifests) so am not sure why this is failing.

Thanks

Bill Lowry (IWM)

The default max size for attachement is 1 MiB, maybe too small if e.g. MD5 files becomes relatively big, I should increase to 2 or 4 MiB...

In the meantime you can use --attachment-max-size 2000000 (short -s 2000000) for tweaking the check.

@JeromeMartinez , I have run into this exact issue with lengthy DPX sequences and attached MD5 manifests and would much appreciate an increase if it doesn't create other problems. I remember you said FFmpeg can have some problems with large attachments.

Thanks @JeromeMartinez that worked for me. I have at least 1,000 files bigger than this so I expect I'll include it by default into my commands.

The issue is with 100+ MB files, MD5 files are not so big :).
