MPEG HEVC Support in GPAC
Clone this wiki locally
The playback support is powered by the open-source OpenHEVC decoder.
All profiles should be supported, interlace is not supported yet. The support is based on the study text of HEVC file format.
MP4Box -add file.hvc -new file.mp4
Adds file.hvc (Annex B format) to the given file.
The default import format uses
MP4Box -add file.bin:FMT=HEVC -new file.mp4
FMT is used to indicate the format is HEVC, and can be omitted if the file extension is
MP4Box -add file.hvc:fps=50 -new file.mp4
FPS is by default
25, and should be specified most of the time as VUI timing is not yet parsed.
MP4Box -info file.mp4MP4Box -info ID file.mp4
Gives info on the file or on the track.
MP4Box –raw <trackId> file.mp4
Exports an HEVC file to annex B format.
All DASH operations from GPAC (client and MP4Box) are supported on HEVC, including bitstream switching modes using hev1. For more information on DASH, see here.
All MPEG-2 TS operations from GPAC (client and MP42TS) are supported on HEVC. MP42TS can be used to generate TS files usable for DASH or for injection in modulation chains; it can also be used to send the TS over an UDP or RTP stream in unicast or multicast mode:
./mp42ts -prog=hevc.mp4 -dst-file=test.ts
