Split HEVC video into pieces of less than 1 second
28 septembre 2019, par VadimI am trying to split 3-second HEVC video 240fps into 5 parts less than 1 second.

Title : GoPro H.265
Language : English
Encoded date : UTC 2016-05-14 03:54:07
Tagged date : UTC 2016-05-14 03:54:07
Color range : Full
Color primaries : BT.709
Transfer characteristics : BT.709
Matrix coefficients : BT.709
Codec configuration box : hvcCFFMPEG command :
ffmpeg -y -i output240.mp4 -c copy -segment_time 0.6 -f segment output%0d.mp4
But it cuts into 3 parts 1 second long each
With h264 there is no such problem.
If i`ll reincode h265 to h265 with parameter -x264-params keyint=1:scenecut=0.//ffmpeg -i testVideo.mp4 -c:v libx264 -x264-params keyint=1:scenecut=0 -c:a copy output.mp4
It is all ok.
Is there any option to split without encoding ?

how to choose ffmpeg video mp3 audio version id ?
7 juin 2013, par UlteriorI am having issues on ffmpeg encoded video files audio tracks. My encoded video contains ID for audio track as extracted from mediainfo :
I use CODEC_ID_MP3 in guess_format "mov" container for quicktime
Audio
ID : 2
Format : MPEG Audio
Format version : Version 2
Format profile : Layer 3
Codec ID : .mp3
Duration : 2s 916ms
Bit rate mode : Constant
Bit rate : 128 Kbps
Channel(s) : 1 channel
Sampling rate : 16.0 KHz
Compression mode : Lossy
Stream size : 45.3 KiB (2%)
Language : EnglishThis is not recognized on a vanilla codecless installation of windows 7, only played by k-lite codec libmad
I have noticed, that another test file contains similar mp3 track and is played by media player OK :
Audio
ID : 2
Format : MPEG Audio
Format version : Version 1
Format profile : Layer 3
Mode : Joint stereo
Mode extension : MS Stereo
Codec ID : 6B
Duration : 1mn 9s
Bit rate mode : Constant
Bit rate : 320 Kbps
Channel(s) : 2 channels
Sampling rate : 44.1 KHz
Compression mode : Lossy
Stream size : 2.67 MiB (38%)
Writing library : LAME3.98The difference I noticed is in Format version number and Codec ID, which is Version 2 from ffmpeg output - I couldnt locate this version setting in ffmpeg source files, so my question is - is there a way to influence this format version identificator and set the codec id as in above playable video ?
