Creating farms of unique websites

avcodec/movtextdec : Simplify checking for invalid extradata
17 octobre 2020, par Andreas Rheinhardtavcodec/movtextdec : Simplify checking for invalid extradata
Every font entry occupies at least three bytes, so checking early
whether there is that much data available is a low-effort way to exclude
invalid extradata. Doing so leads to an overall simplification.Reviewed-by : Philip Langdale <philipl@overt.org>

FFMPeg 2 pass c#
30 mars 2014, par zerosandonesI have been scouring through the web to try and find a good walkthrough of
FFMPeg
and it's nuances.I have a working setup currently. It is a two pass encoding. If I use a cmd window and use the following args :
ffmpeg -i c :\temp\175663.lbl.mp4.mps -vcodec mpeg4 -b:v 1300k -s
640x360 -aspect 16:9 -pass 1 -r 29.970 -an -f rawvideo -y NUL &&
ffmpeg -i c :\temp\175663.lbl.mp4.mps -vcodec mpeg4 -b:v 1300k -s
640x360 -aspect 16:9 -pass 2 -r 29.970 -acodec libmp3lame -ab 128k -ar
48000 c :\temp\encoded\175663.NTP.mp4I get a log file in the
ffmpeg.exe
directory. Which I believe to be a valid good log. I also get a valid good mp4 file. However, I have no idea whether the log file is actually used on pass2. If I run just the second pass (everything after the &&) in a cmd window all by itself. I get a valid mp4 file. Why is there no error ? This makes me suspect that the original pass isn't being used at all for the second pass.Secondly, how can I programmatically delete the log of pass1 ? Is there a naming convention that I can key into ? Eventually this application will be running on multiple threads on the same/other machines. So I can't exactly just delete *.log from the ffmpeg folder. Is there a way to name the files as they are created ?
Lastly, I do not seem to be able to start a new process in C# with the argument above. If I omit the ffmpeg (because the process is starting ffmpeg itself) I get an error on &&. I don't think it likes trying to do two passes. If I do one pass at a time, I do not get a log file to even try to use on the second pass.
Any info would be amazing. Thank you for your time in advance !
