Как преобразовать видеофайл из mkv в формат, поддерживаемый телевизором?
2078
Alex
У меня есть видео файл MKV, который содержит следующее содержание:
> mkvmerge --identify original.mkv File 'original.mkv': container: Matroska Track ID 0: video (V_MPEGH/ISO/HEVC) Track ID 1: audio (AAC) Tags for track ID 0: 7 entries Tags for track ID 1: 7 entries
Но «стандартное» преобразование с использованием avconvне работает (Ubuntu 14.04), также как и предложение, которое я нашел в другом месте (см. Ниже и ниже…). Исходный файл не может быть воспроизведен mplayerни при воспроизведении с жесткого диска, подключенного к телевизору.
Как решить эту проблему, чтобы преобразовать файл в более «нормальный / стандартный» формат, чтобы его можно было воспроизводить mplayerи показывать по телевизору?

Just use the latest version of ffmpeg. It seems like the development of avconv is way behind. Since there were some changes regarding mp4 container and HEVC your "multiplexer" has to support them, this is probably the reason why you have this output in your first try:
[mp4 @ 0x11daf60] track 0: could not find tag, codec not currently supported in container
Since you are on Ubuntu 14.04 you can not just install ffmpeg using sudo apt-get install ffmpeg (works for Ubuntu > 14.04) but you can either update to 16.04, compile ffmpeg from sources or just install precompiled static builds.
After installation you can either "remultiplex" mkv to mp4:
ffmpeg -i original.mkv -c:v copy output.mp4
Or transcode mkv H.265 to mp4 H.264:
ffmpeg -i original.mkv -c:v libx264 output.mp4
In order to play it you need the corresponding decoder (either software or hardware). You also have to pay attention which profile and level your decoder supports (in case your TV has a HW decoder). But transcoding to H.264 should do it on every TV nowadays.
