ffmpeg ... "Impossible to convert between the formats supported by the filter"
27 novembre 2017, par hydra3333Using the latest ffmpeg master built as at 2017.11.26, I’m having trouble deciphering what the error messages means and, more importantly, what to do about them.
Changing from -vf to -filter_complex did nothing (I had to try).
The main error message seems to beImpossible to convert between the formats supported by the filter
I have tried to insert "format=" and "scale" before/between/after yadif and unsharp_opencl but to no avail.
I wonder, could it be something to do with needing hwupload/hwdownload/hwmap or is that a red herring ?
What am I doing wrong ?

How to avoid the "text relocation" error by ffmpeg library on Android x86
16 octobre 2017, par Tank2005My environment is Qt 5.9 for Android on Windows 10 64bit. NDK is r10e and SDK Level is 16(Those sdks are recommended version by Qt development team).
I built a ffmpeg 3.4 source code as .so files on Ubuntu 16.04.3 LTS. Those library has no error on ARM architecture Android. But, on x86 Emulator, "Text realocations" alart is shown like this.
I rewrite configure with "disable-asm, disable-yasm" referd from this site’s old posts.
This hereby removed some errors. But only one library has a problem.
I also tried the method of deleting "strtod.o", But it seems no effect. My current build configure is that. Does anyone know a better way ?
