Segfault playing H264 video with v4l2m2m hw acceleration on QCom Venus decoder even though ffplay works

Important Information

Provide following Information:

• mpv 0.36.0 Copyright © 2000-2023 mpv/MPlayer/mplayer2 projects
  built on UNKNOWN
  libplacebo version: v6.292.1
  FFmpeg version: 6.0-6
  FFmpeg library versions:
  libavutil 58.2.100
  libavcodec 60.3.100
  libavformat 60.3.100
  libswscale 7.1.100
  libavfilter 9.3.100
  libswresample 4.10.100

• Linux Distribution and Version: Debian stable with mpv from sid

• Source of the mpv binary: https://packages.debian.org/sid/mpv

• If known which version of mpv introduced the problem

• Window Manager and version: KDE Wayland 5.27.5

• GPU driver and version: FD618 Vendor ID 0xe150 Device ID 0x229a Driver Vendor mesa/msm Driver Version 22.3.6.0

Reproduction steps

Download an H264 video, for example from https://bug1619882.bmoattachments.org/attachment.cgi?id=9149605 to ~/Downloads/youtube.mp4. Then run mpv on a device with QCom Venus Decoder (such as SC7180 based Acer Spin 513): mpv --hwdec=v4l2m2m-copy ~/Downloads/youtube.mp4

Expected behavior

Video plays and watch -n 0.5 grep venus /proc/interrupts shows increasing interrupt counter, just as SDL_VIDEODRIVER=wayland ffplay -codec:v h264_v4l2m2m -t 10 ~/Downloads/youtube.mp4.

Actual behavior

Segmentation fault in v4l2_dequeue_v4l2buf libavcodec60

Sample files

Sample files needed to reproduce this issue can be uploaded to https://0x0.st/
or similar sites. (Only needed if the issue cannot be reproduced without it.)
Do not use garbage like "cloud storage", especially not Google Drive.

Reproduce with mpv --no-config --hwdec=v4l2m2m-copy using the H264 sample, then inspect the crash location in src/libavcodec/v4l2_context.c:332 and compare it with the working ffplay command. Done means the sample plays with QCom Venus v4l2m2m acceleration without a segmentation fault.
