#2866: support --verify option for lossless encoding to decode the output in
parallel to compare to original

Summary of the enhancement request:
The FLAC utility has an option called --verify
{{{
ENCODING OPTIONS
-V, --verify
Verify a correct encoding by decoding the output in parallel
and comparing to the original
}}}
This is an option for the paranoid, but is very helpful in lossless
encoding for digital preservation, especially when the original data is
considered for disposal after encoding to a lossless derivative.
How to reproduce:
I use FFmpeg to convert uncompressed video into lossless video in ffv1.
Currently I do this with two passes:
- pass 1 encode the source video to both an ffv1 output and framemd5
output
- pass 2 encode the ffv1 output to a new framemd5 output
- make sure the two framemd5 outputs are identical
Almost every time the two framemd5s match but on very (very) rare instance
they differ. This happened to me recently.
For pass 1 (decode source and encode to ffv1 and framemd5) I ran:
{{{
ffmpeg -v warning -stats -vsync 0 -i "/Volumes/Desktop-1/Capture
Scratch/ATW/ATW00296/objects/SXL00257.mov" -map 0:v -map 0:a -c:v ffv1 -vf
"setfield=bff" -g 1 -c:a copy "/Volumes/Desktop-1/Capture
Scratch/ATW/ATW00296/objects/SXL00257_ffv1.mov" -f framemd5 -an
"/Volumes/Desktop-1/Capture
Scratch/ATW/ATW00296/metadata/submissionDocumentation/logs/SXL00257.framemd5"
ffmpeg version 1.1.git Copyright (c) 2000-2013 the FFmpeg developers
}}}
For pass 2 (decode ffv1 from pass 1 and encode that to framemd5) I ran:
{{{
ffmpeg -v warning -stats -i "/Volumes/Desktop-1/Capture
Scratch/ATW/ATW00296/objects/SXL00257_ffv1.mov" -f framemd5 -pix_fmt
uyvy422 -an "/Volumes/Desktop-1/Capture
Scratch/ATW/ATW00296/metadata/submissionDocumentation/logs/SXL00257_ffv1.framemd5"
}}}
Full logs for both commands below.
The resulting framemd5s, when diff'ed, had one line of difference. I
looked up the corresponding frame in the ffv1 output and it had the
rainbow error effect that you'd normally see in corrupted ffv1. I
extracted a few frames surrounding the error and uploaded it here:
http://dericed.com/samples/SXL00257_glitch.mov. Unfortunately this error
isn't easily recreated but a rare occurrence.
Finding this glitch validated the two pass process, since the output of
the first pass that encoded the ffv1 didn't provide a clue that the output
was not lossless but had an error introduced. This reminded me of the
--verify option in the FLAC utility. Is a --verify option feasible in
ffmpeg when a level of paranoia is needed to validate the output.
PASS 1
