check some changes / WIP in my tree

Hi - I was doing some light vdr changes this weekend - some packages (and vdr) compile fine - see my changes

I am using a dvb.mk in package/kernel/module location instead of your solution atm

my other patches are here: https://github.com/plntyk/misc/tree/master/2021-03_vdr/openwrt-vdr
there are some other patches of linux distros there - some plugins , some fixes - as vdr heavily uses custom patches

vdr 2.4.6 and some plugins compile fine - some plugins / vdr programs like w_scan_cpp require more work because they always want to link against the original vdr sources / header files that probably should be installed via InstallDev

the Make files of VDR / plugins are also not that portable / cross-build friendly

Hi, sorry for late reply.

DVB modules packaging is hard to maintain (one good is that hardly any new demodulators, bridges, etc. are added to media subsystem), You'll need well maintianed wiki page where each card will have described every module necessary to make it work. Similar is my approach, where I added meta packages in v4l-dvb/devices.mk which pull necessary dependencies for each known card. The downside is someone needs to add their devices.
BTW the upside of using v4l-dvb build system is You can build the modules with SDK, so one can use them with the release image. The upside would not matter if dvb.mk will end up in upstream.

The VDR is nice because it's not a resource hog, but yeah, the additional patches are a drag but sometime necessary.

vdr 2.4.6 and some plugins compile fine - some plugins / vdr programs like w_scan_cpp require more work because they always want to link against the original vdr sources / header files that probably should be installed via InstallDev

It's hard to handle that in straight manner, some plugins search for headers in well known places but other still think they are built in VDR source tree, sometime small patch to Makefile is enough, sometime not.

the Make files of VDR / plugins are also not that portable / cross-build friendly

Yeah, had to patch that in few places. Still it's easier than working with autoconfig/autotools.

Good news is that VDR 2.4.7 has most of the patches included, but You still might have to incorporate some for build with musl, check this tree for latest ones: https://github.com/glenvt18/vdr/commits/vdr-2.4.6.

I plan to get back to this in summer (maybe earlier), since I have two units of PCTV Broadway which I want to port to OpenWrt. These are ramips devices with embedded USB stick for DVB reception and transcoding board. The main board is easily supportable except the transcoding board. You might get one (if interested) for cheap on eBay or some such.

For now I'll keep this PR open, until I start working on the mentioned devices.
