First of all, great program. Love how light, flexible and fast FFAStrans works. Keep up the good work! Very thankful for this program!
I work for a non-profit local TV station. We have been looking for a good network watch-folder encoder for a while. Tried Adobe and Sorenson Squeeze for a few months, both had issues and shortcomings.
Knowing FFmpeg already, I was excited to see what FFAStrans could do. Setup took a little longer then the "fancy" commercial encoders, but also because FFAStrans has way more options hidden inside it. Settings are for setting!
Most things have been running smoothly. Editors put their MPEG2 masters in one of a handful of input watchfolders, FFAStrans picks them up and spits out the encoded files to the output folders. (With the SyncBack util then moving the original master to storage, uploads some formats to FTP and all that good automated stuff).
One tiny "issue" however.
Not sure howcome, but when someone submitted a H264 file in MP4 container from the HandBreak DVD ripper, I notice that the monitor window shows the "Process @node" going through the usual steps of "A/V Media@ENCODER" then "Custom FFmpeg@ENCODER" and lastly "Delivery@". But the "Status" shows up as "Checking AviSynth script (TTL: 1200)" (and counting down from 1200 sec.) instead of the usual "Percentage %" and "NNNN / NNNN @ NN FPS" for the respective steps i see when people submit MPEG2 files. FFMPEG process seems to be churning on the file in the background just fine though, at expected speed for completion. But in that case it delivers [filename].avs files in the output folder. The content of the .avs files seems to be the AviSynth script used in the processing of the file.
It was an easy fix, since I realized I didnt need the decoder as long as I wasnt adding filter, FFMPEG functionality naturally decoding just fine without an intermediate step, faster too I imagine. So this is now only a problem with the workflow I have for adding watermark and timecode, with DVD rips from Handbreak that is.
Added print from MediaInfo below. Suppose could be any of these properties that cause the issue with AviSynth, someone would have to do a bunch of testing!
Its not an issue for me currently, as we likely wont get DVD rips that need watermarking. But seeing as I love FFAStrans, and this was the only issue I found, this is what I submitted to the forum!
By the way. Could someone explain how they set up network farm for encoding. Is it as simple as having multiple machines start the exe from the same mapped network drive, minding the full access to cache folder too?
Best Regards!
