Hi everyone,
I'm running into a persistent issue when playing videos in my Flutter app on Android using video_player (which uses ExoPlayer under the hood). The app throws the following error:
androidx.media3.exoplayer.ExoPlaybackException: MediaCodecVideoRenderer error, index=0, format=Format(1, null, null, video/avc, avc1.4D401F, -1, null, [480, 854, 29.998442, ColorInfo(BT709, Limited range, SDR SMPTE 170M, false, 8bit Luma, 8bit Chroma)], [-1, -1]), format_supported=YES
Caused by: androidx.media3.exoplayer.mediacodec.MediaCodecRenderer$DecoderInitializationException: Decoder init failed: c2.exynos.h264.decoder
Caused by: java.lang.IllegalStateException: Block model is only valid with callback set (async mode)
It shows up as:
Error initializing video controller: PlatformException(VideoError, Video player had error ...)
What I’ve checked so far:
The video is H.264 (video/avc) and plays fine on other devices.
I’ve tried different video resolutions and formats, still the same issue.
The ExoPlayer format_supported=YES suggests the format should work.
Device:
Samsung (Exynos chipset)
Android 11+
💻 My video player code (Flutter) is here:

If anyone has faced this before or has suggestions on handling ExoPlayer codec issues in Flutter, I'd appreciate your help!
Thanks in advance!
