Hello. This is my first time on ffmpeg mailinglist, so i'm in deep water.... I just got my Raspberry Pi 4 (RPi4) and i'm trying to encode with FFMPEG. I'm using "Buster" OS I already have a RPi3 with FFMPEG and it works fine. (OS = Stretch). I have downloaded all dependicies and ffmpeg is working So I have compiled FFMPEG with the exact same setting in configure:

|configuration: --arch=armel --target-os=linux --enable-gpl --enable-omx --enable-omx-rpi --enable-nonfree --enable-mmal|

|I have then used the same test file 'test.ts' containing 3 tracks: 0:0 video 264, 0:1 audio mp2, 0:3 teletext. | |I have startet the encoder with this commandline:

||ffmpeg -fflags +igndts -ss 00:01:00 -c:v h264_mmal -i 'test.ts' -to 00:05:00 -map 0:0 -map 0:1 -c:v h264_omx -b:v 1500k -flags +global_header -c:a:0 copy 'test.mp4'|

|But no mather what i do FFMPEG is hanging right after the first encoder line and the sreen looks like this:| |[h264 @ 0x2d950e0] decode_slice_header error [h264 @ 0x2d950e0] no frame!

I have turned off 4K and analog output and that did't make a change. Also tried with out the flags. So is it me doing something wrong or is it because, that RPi4 has a new Broadcom Video chip and FFMPEG is not ready to use it yet?| |Best ragards RAJensen | ||
