My ffProbe script only seems to work with MKV files Just learned about ffprobe yesterday, and I was able, after much googling, to assemble a command line BAT file to get the meta info I want.  Then, it turns out that it only works about half the time.  After some experimentation, it seems that it's working only on MKV files.  

I don't know if there's a bug going on here, or if my command line needs improvement.  Maybe ffProbe only works on certain files, but I was assuming it would work on most popular vid formats.

I'm using AutoHotKey to create a BAT file, which I then launch.  So we really just need to look at the BAT file.

Here's my BAT script...

C:\PROGRA~1\ffmpeg\bin\ffprobe.exe -pretty -select_streams v \
-show_entries \
format=filename,size,duration,bit_rate:stream=codec_name,codec_type,bit_rate,width,height,display_aspect_ratio \
-of ini \
"S:\myTVshows\SampleName - S01E01 - SampleTitle.mp4"


After this is run, the console outputs only the #ffprobe output header and then hangs.  If it runs on an mkv file, then it instantly outputs all the data I want, as expected.

Update: when I add -report as a parameter, I get the report log file, of course... but I also get the output I want (instead of it hanging as before).  I wonder if it means this is a bug.

Notes


I reduced the path for ffprobe to 8.3 format so I wouldn't have to worry about quotes around that part.
I'm working with a very current install of ffmpeg/ffprobe (ffmpeg-20170404-1229007-win64-static).

Link to Log file when '-report' param was added
Since the implementation of the new decode API, ffprobe's readout for MP4 files takes much longer to be printed, and depends on the duration of the video. Switch to a version earlier than April 2017.
