The mxf_d10 muxer is very picky regarding the input it accepts: The only video accepted is MPEG-2 with absolutely constant bitrate, i.e. all packets need to have exactly the same size; and only a few bitrates are accepted. The sample file used did not abide by this: Writing the first packet (a video packet) errors out and afterwards an audio packet from the muxing queue has been written. That's all besides metadata (which this test is about). The FFmpeg cli returned an error, but said error has been ignored by the md5 test. This commit changes the test to actually send a compliant stream to the muxer, so that it does not error out; furthermore, the test is changed to explicitly check the metadata instead of it only being implicitly included in the md5 checksum. The compliant stream is created by our encoder at runtime. Finally, the test now also covers writing user-specified product/company/version identification.
