After the data is shipped to OSS, you can use decompression tools to decompress the data. ![]() You should only use these in extreme cases if you have reached a specific bottleneck when using the default settings. When you ship data from Simple Log Service to Object Storage Service (OSS), you can use Snappy to compress the data. In addition you can also specify the following optional flags that can be used to create Hap movies that are highly optimized for specific playback hardware. Along with the other options you choose, you must pass -enable-libsnappy to the configure script before building.įor Hap movies use the following command: ffmpeg -i yourSourceFile.mov -c:v hap outputName.movįor Hap Alpha movies use the following command: ffmpeg -i yourSourceFile.mov -c:v hap -format hap_alpha outputName.movįor Hap Q movies use the following command: ffmpeg -i yourSourceFile.mov -c:v hap -format hap_q outputName.mov Visit the FFmpeg wiki for instructions on how to compile FFmpeg for macOS, Windows and Linux. Ubuntu Linux and some other distributions have Snappy support enabled The semi-official Windows FFmpeg downloads have Snappy support enabled. On macOS you can use Homebrew to install FFmpeg with the following command: brew install ffmpeg -with-snappy Otherwise install FFmpeg using one of these methods: If the last line of output ends with Vidvox Hap encoder then you can encode Hap. You can check that your version of FFmpeg can encode Hap using ffmpeg -encoders | grep hap If you already have FFmpeg on your system with Snappy enabled, you can skip this step. ![]() In either case be sure that Snappy is enabled as part of the binary. If this is your first time using FFmpeg you may need to install it on your system, or compile it from source.
