How to fix H.265 / hevc encoded MP4 video files

H.265 / HEVC is a new MP4 video code, following the new standard after H.264. The H.265 standard improves the relationship between video code stream, encoding quality, delay, and algorithm complexity, and reaches optimization settings relative to the previous generation. With the H.265 slowly popular, the commonly used equipment in the market is: Samsung camera, Daojiang drone, Apple mobile phone, Huawei mobile phone, GOPRO running camera, etc. If you encounter anomalies in shooting: the battery is low, unusual, copy is incomplete, storage damage, etc., the H.265 encoded MP4 file is corrupted, video cannot be rendered, playback failed, the H.265 encoded MP4 file repair is more H.264's encoded video is more difficult. For the H.265 encoded MP4 video damage, the best way is to be fixed-class fixes. First analyze the data of the video, use the coding characteristics to repair the damaged video, the repair result of this method is perfect, smooth picture, sound synchronization, support editing. The following is a typical H.265 video coding for reference: General Complete name Samsung SAM_1117.MP4Format MPEG-4Format profile Base Media / Version 2Codec ID mp42 (qt / isom / hvc1) File size 289 MiBDuration 34 s 720 msOverall bit rate mode VariableOverall bit rate 69.9 Mb / sEncoded date UTC 2018-02-20 19Tagged date UTC 2018-02-20 19 Video ID 1Format HEVCFormat / Info High Efficiency Video CodingFormat profile Main @ L5.1 @ MainCodec ID hvc1Codec ID / Info High Efficiency Video CodingDuration 34 s 701 msBit rate 69.7 Mb / sWidth 3 840 pixelsHeight 2 160 pixelsDisplay aspect ratio 16Frame rate mode ConstantFrame rate 29.970 (30000/1001) FPSColor space YUVChroma subsampling 4Bit depth 8 bitsBits / (Pixel * Frame) 0.28Stream size 288 MiB (100%) Language EnglishEncoded date UTC 2018-02 -209Tagged Date UTC 2018-02-20 19Color Range Fullcolor Primaries Bt.709Transfer Characteristics Bt.709Matrix Coefficients Bt.709Codec Configuration Box HVCC Audio ID 2FORMAT AA C LCFormat / Info Advanced Audio Codec Low ComplexityCodec ID mp4a-40-2Duration 34 s 720 msSource duration 34 s 688 msBit rate mode VariableChannel (s) 2 channelsChannel layout L RSampling rate 48.0 kHzFrame rate 46.875 FPS (1024 SPF) Compression mode LossySource stream size 807 kib (0%) Language englishncoded Date UTC 2018-02-20 19tagged Date UTC 2018-02-20 19MDHD_DURATION 34720
