Also tested with git build g6b978da built on 20151130, same result.

It works if I add a "aformat=sample_rates=44100" step in the audio filter chain, but this was not needed before.

Please test current FFmpeg git head.

Spent a few hours failing to build the latest version on my computer (only worked with static builds before). Will revisit this when I have more time to spare.

Replying to mstrandgren:

What is the issue? FFmpeg is supposed to build on many different systems out-of-the-box with ./configure --enable-gpl && make ffmpeg.

only worked with static builds before

All providers of static builds provide a current build, you provided console output for a release though. (The message on http://johnvansickle.com/ffmpeg/ concerning release builds has improved since you opened this ticket.)

Please provide the needed input files (and please understand that you make an analysis much harder by separating the command line from the console output / not providing the command line).

comment:6 by Martin Strandgren, 9 years ago

But I did provide the command line, it's right there in the bug description?

comment:7 by Martin Strandgren, 9 years ago

The input files are here: https://www.dropbox.com/s/67bdul8jqwpxbx2/files.zip?dl=1 (Trac does not allow files larger than 2.5M, this seems easier for everyone).

The filter graph is too complex for FFmpeg to figure out a sample rate that suits all the paths. New heuristics could be added, but they would never cover all the cases.

Since you are controlling almost everything else, I suggest you disable automatic conversions and insert conversion filters explicitly.

Also, you should run different connected components of the graph in different graphs. That means audio and video here.

Last of all, in the future, if you want to increase your chances of getting attention fast, you should trim your command line to keep only what is necessary to exhibit the problem.

comment:11 by Martin Strandgren, 9 years ago

I reported it because it was a regression, it worked in 2.8 but not in 2.8.3, as advised in the irc channel. I added a conversion filter as you said, and it works well.

Last of all, the responses for this issue have been blazingly fast, but I'll make better reports in the future nonetheless :)
