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!
[mpegts @ 0x2d904b0] PES packet size mismatch

I can't figure this out as it is working on RPi3.
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?|
