avformat/matroskaenc: Don't write \0 unnecessarily Writing the duration SimpleTag is special: It's size is reserved in advance via an EBML Void element (if seekable) and this reserved space is overwritten when writing the trailer; it does not use put_ebml_string(). The string to write is created via snprintf on a buffer of size 20; this buffer is then written via put_ebml_binary() with a size of 20. EBML strings need not be zero-terminated; if not, they are implicitly terminated by the element's length field. snprintf() always zero-terminates the buffer, i.e. the last byte can be discarded when using an EBML string. This patch does this. The FATE changes are as expected: One byte saved for every track; the only exception is the matroska-qt-mode test: An additional byte is saved because an additional byte could be saved from the enclosing Tags length field.

fftools/ffmpeg: use the sync queues to handle -frames Same issues apply to it as to -shortest. Changes the results of the following tests: - matroska-flac-extradata-update The test reencodes two input FLAC streams into three output FLAC streams. The last output stream is limited to 8 frames. The current code results in the first two output streams having 12 frames, after this commit all three streams have 8 frames and are the same length. This new result is better, since it is predictable. - mkv-1242 The test streamcopies one video and one audio stream, video is limited to 11 frames. The new result shortens the audio stream so that it is not longer than the video.

fate/matroska: Add test for updating CodecPrivate from packet sidedata containing updated extradata, in this case a new FLAC streaminfo. Furthermore, it also tests that the Matroska muxer is able to preserve uncommon channel layouts by adding Vorbis comments to the CodecPrivate.
