[FFmpeg-devel] [PATCH][RFC] Use AVERROR_DEMUXER_NOT_FOUND retcode

[Andrey Utkin]

I was asked "how to distinguish error cases of unsupported input format and of broken file".
I figured out that constant AVERROR_DEMUXER_NOT_FOUND is currently unused, and AVERROR_INVALIDDATA was returned instead in av_probe_input_buffer().
I didn't test this change yet. I just ask if this point is valid.
