I found this https://trac.ffmpeg.org/wiki/HowToBurnS ... sIntoVideo
It seems we need --enable-libass as well.

EDIT:

In order to have support of dvb teletext subtitles we need that compile switch as well

--enable-libzvbi

I started but faced with some difficulties but will finish it when have time.
You can track my progress from here https://github.com/bmihovski/openrov-ff ... r/build.sh
I am using my docker image for crosscompile environment https://hub.docker.com/r/boyan/samygo_oscam/

Feel free to push changed to the repo I will merge them or grant you access.

Well. I tried also. I did have problem with static build with x264 library. I did have set enable-static parameter but after made compile did have dynamically link library. Have you statically or dynamically link liblary after made cross compile?

Build libx264 static only, if ffmpeg compilation finds only libx264.a it will build static. Usually same goes for other libs.
Btw arch=armhf is wrong :)

yea should be:

Code: Select all

arm=archv7 
it works for cross compile without other libs.

I meant "hardfloat" is wrong, should be soft. Doesn't really matter if omitted anyway, you can also specify arch in CFLAGS if you really want to.

thx :D
It's works but so slow that it has not sense. On Windows speed is normaly about x1 but on TV speed is below x0.5 :roll:

Maybe a problem is because the cross-compilation was made for ARMv6 and not for ARMv7 :?:

No, it's just that there's no HW encoding support and arm processor is capable of nothing without it :)

Code: Select all

# echo $CFLAGS
-march=armv7-a -mfpu=neon -mtune=cortex-a9
# readelf -A ffmpeg
Attribute Section: aeabi
File Attributes
  Tag_CPU_name: "7-A"
  Tag_CPU_arch: v7
  Tag_CPU_arch_profile: Application
  Tag_ARM_ISA_use: Yes
  Tag_THUMB_ISA_use: None
  Tag_FP_arch: VFPv3
  Tag_Advanced_SIMD_arch: NEONv1
[...]
I guess ARMv6 NEON is what ffmpeg detects/can reach, not enough for realtime x264 anyway.
