This code removes filters which can not take spdif inout. This was made so that PCM filters are transparently dropped in spdif mode. This entered an endless loop with: --af=lavcac3enc:::2 --audio-channels=5.1 The forced number of output channels is incompatible with spdif. It's trying to insert af_lavrresample as conversion filter to compensate for it. Of course this doesn't work, which triggers the PCM filter removal. Then it goes on normally - since the new state is exactly as before, it will try the same thing again, forever. Fix by reusing the retry counter, which is a very dumb but very effective measure against these cases of filter negotiation failure. We could try to be more clever (for example, if the removed filter is a conversion filter, we can be sure this won't work, and error out immediately). But better keep it simple and robust. |
