OMXPlayer errors in Stretch Lite on Pi Zero 11-2018 - will not show video

[RexRoper]

Hello to All, I have a new Pi Zero W and I have loaded the latest Stretch Lite and attached an RPi Camera v2.1. I have performed sudo apt-get update and then sudo apt-get upgrade and also set memory split to 256. I then issued the command raspivid -t 1000 -o testvid.h264 to capture a 10 second video from the RPi Camera.

When I issue the command omxplayer testvid.h264, I receive the following: pi@CamSolarLab1:~ $ omxplayer testvid.h264 _Video codec omx-mjpeg width 3280 height 2464 profile -99 fps 25.000000 Subtitle count: 0, state: off, index: 1, delay: 0 V:PortSettingsChanged: 3280x2464@25.00 interlace:0 deinterlace:0 anaglyph:0 par:1.00 display:0 layer:0 alpha:255 aspectMode:0 COMXVideo::Decode timeout omxplayer.bin: OMXCore.cpp:786: OMX_ERRORTYPE COMXCoreComponent::FreeInputBuffers(): Assertion `m_omx_input_buffers.size() == m_omx_input_avaliable.size()' failed. /usr/bin/omxplayer: line 67: 4829 Aborted LD_LIBRARY_PATH="$OMXPLAYER_LIBS${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}" $OMXPLAYERBIN "$@" pi@CamSolarLab1:~ $

I have tried numerous attempts to resolve this issue with no positive results. Changing memory split to all other values has no effect. Uninstalling and reinstalling omxplayer has no effect.

I see a line in the Error that indicates: V:PortSettingsChanged: 3280x2464@25.00...my monitor settings are HDMI 1600x900 60Hz. Is 3280x2464@25.00 a standard setting for OMXPlayer or do I need to match my monitor settings?

Any additional insight or suggestions will be greatly appreciated. Thank you

First I would try cutting down the camera resolution: try adding "-w 1920 -h 1080" to your raspivid command and see if that works.

Next I would try disabling the viewfinder: try adding "-n" to your raspivid command. That's likely why you're seeing that PortSettingsChanged.

Let us know how it goes.

Can you show the exact raspivid command you are entering? You appear to have a file testvid.h264 containg mjpeg video which seems surprising.

issued the command raspivid -t 1000 -o testvid.h264

testvid.h264 is the test video file that is installed with Raspbian and can be found in /opt/vc/src/hello_pi/hello_video/ folder. I cannot explain why the h264 extension is used for an mjpeg. Maybe someone more familiar with why the Raspberry Pi Foundation provides the file in this manner can provide an answer.

The hello_video test.h264 file contains h.264 and not mjpeg.
