+/// * `demuxer` - container format name (used to find proper demuxer for it)
+/// * `name` - input file name
+/// * `video_pfx` - prefix for video frames written as pictures (output picture names should look like `<crate_name>/assets/test_out/PFXout00_000000.ppm`
+/// * `limit` - optional PTS value after which decoding is stopped
+/// * `dmx_reg` and `dec_reg` - registered demuxers and decoders that should contain demuxer and decoder(s) needed to decode the provided file.
+///
+/// Since the function is intended for tests, it will panic instead of returning an error.
