Project: repurpose the old Ipad 1st Gen as a TV viewer, thanks to Tvheadend and Pi TVHAT
Limitations of Ipad 1st Gen
- Ipad 1st Gen is stuck on iOS 5.1
- Poor CPU, that makes it laggy for any modern task
- It's a real pain to find and install suitable/available Apps for that iOS version.
- Default Video player app is really limited in term of video codecs and formats supported
Good points of Ipad 1st Gen
- Ipad's SoC has hardware decoder for H264 videos (only Quicktime can benefit from it)
- Quicktime player can play MPEG-TS stream encoded with H264 (video) + AAC (audio) up to FullHD
- a VLC version is available (software decoder only, work great with MPEG2, doesn't work with H264)
- Nice screen (IPS, while limited resolution 1024x768 px)
--> So basically it could be suitable to watch TV on Ipad1 for both TNT "SD" (MPEG2) with VLC or TNT "HD" (H264) with Quicktime internal player (need to re-encode on-the-fly the sound from AC3 to AAC).
The Ipad 1st Gen would be the frontend/player, and the backend (aerial DVB-T TV receiver and streamer) would be done by TVheadend on a Raspberry Pi equipped with Pi TV HAT. On-the-fly re-encoding of the sound from AC3 to AAC takes up to 20% CPU on the Raspi 2.
Then an interface to select channels and lunch the stream to player is needed...
- No exisitng or working native App for iOS 5.1 (based on my searchs)
- It's more flexible to develop for web frontend
- TVheadend has a good Json API
- TVheadend can host some static files served by its webserver
- The old Safari browser supports Jquery up to version 1.12.4
- The old Safari browser does support "vlc://" URL scheme to send video url to VLC
- The old Safari browser support HTML5 Video element to send video url to Quicktime
- available version of Tvheadend on Raspbian Buster repositories is 4.2, but it doesn't support SPAWN in stream profiles -> solution: tvheadend_4.3-1805_gdca46eedd_armhf.deb for Raspbian Buster https://cloud.disroot.org/s/y3YtbkrgFodCwdH (from reference https://tvheadend.org/issues/5673 )
For Raspberry Pi2 or Pi Zero, when using a Wifi USB dongle to enable Wi-Fi Automatic Reconnect:
In /etc/network/interfaces put:
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
