hyperion-webos
hyperion.ng grabber for webOS.
This piece of software does high-framerate/low-latency capture of contents displayed directly on webOS TVs and transmits these frames to hyperion.ng over the network.
Based on reverse-engineered internal system APIs. Still highly experimental.
If you are looking for a user-friendly UI that ships this piece of software check PicCap. This application mainly is the underlaying service for this software.
Known issues
libvt: may cause flickering or "No Signal" until reboot- Everything is based on highly platform-specific reverse-engineered internal system APIs. Standard no-warranty clauses apply.
Backends
This software uses multiple capture backends, that may work differently on some webOS versions/hardware platforms.
| Backend | Description | Video | UI | Framerate | webOS |
|---|---|---|---|---|---|
libdile_vt |
Low-level library used internally by libvt | ✘¹ | 60 | 3.x+ | |
libvt |
High-level video rendering library, uses OpenGL, may cause flickering/"No signal" until reboot | ✘¹ | ~30 | 3.x+ | |
libvtcapture |
High-level video capture library, uses Luna bus, could possibly work without root (not now) | ~25 | 5.x+ |
¹ - UI capture could be added at some point in the future
Running
hyperion-webos together with *_backend.so libraries need to be copied onto
the TV, eg. into /tmp directory.
cd /tmp
./hyperion-webos --help
./hyperion-webos -S -b libdile_vt -a 10.0.0.1Issues reporting
When reporting issues please include result of the following command:
grep -h -E '"(hardware_id|core_os_release|product_id|webos_manufacturing_version|board_type)"' /var/run/nyx/*This contains model/hardware/region/software version, without any uniquely identifiable information.
If a segfault/crash occurs, a crashlog file will be generated in /var/log/reports/librdx
or /tmp/faultmanager/crash/. This contains process memory dump and backtrace,
but should not contain any uniquely identifiable information. (though, this is not guaranteed)
