error decoding video (receiving frame): End of file

[sergiohinniger]

I have a RPi4 and use attract with X11 on top of Raspian Lite. Recently i've updated attract mode to 2.6.2 and apparently everything was fine, the videos are playing fine, but in the console appears endless error messages: "error decoding video (receiving frame): End of file"

I have reinstalled all packages and dependencies (using apt --reinstall install) and recompiled attract without luck. I dont know what could it be.

I compiled attract for Pi 3 and for a standard x86 PC and get the same errors during the screensaver when it's playing mp4's (snaps). It happens randomly on version 2.6.2, but not on 2.6.1. It's similar to issue #699 (locks up on Pi 3 during screensaver), and on x86 computers, it exits attract with "error decoding video" messages in the log.

In my case, i have snaps running, and they are working fine, but i dont know why, the console keeps showing that error

The error put in the log file is generated by the src\media.cpp file (line 789). It looks like an issue with avcodec_send_packet or the associated codec.

I installed attract using this tutorial: https://github.com/mickelson/attract/wiki/Compiling-on-the-Raspberry-Pi-4-(Raspbian-Buster) The ffmpeg library is old, so i compiled ffmpeg, but the error persists

I've got Pi 2's, 3's and 4's. I'll try this on the Pi 4 and see what happens. I suspect the problem is a mismatch between the libavcodec that's supported by the OS. According to https://packages.debian.org/search?suite=buster&searchon=names&keywords=libavcodec Buster is using libavcodec58. Are you using the Buster or Bullseye RaspiOS? What output do you get from attract --version ?

i have compiled ffmpeg and didnt solve, but i think i solved the issue. I compiled ffmpeg with mmal, and compiled attract with xinerama and mmal, without drm, like this.:

mkdir ~/build
cd ~/build
git clone --depth 1 https://github.com/mickelson/attract attract
cd ~/build/attract
make -j5 USE_XINERAMA=1 USE_LIBCURL=1 USE_MMAL=1 EXTRA_CFLAGS="-w -Wno-psabi -Wno-deprecated -Wno-deprecated-declarations -Wno-narrowing"
sudo make install USE_XINERAMA=1 USE_LIBCURL=1 USE_MMAL=1
cd ~
rm -rf ~/build

I need Xinerama to use a second monitor as marquee, and with only mmal and DRM its not possible. Now is working. Tks for the help

710 is the same as this prior issue.
