[iOS] Error while reading movie during project import

[AytoMaximo]

Bug description

Hi! I have a simple test project, which should start a video play on my raw image component after app starts. However after CICD the video is gone and I've found the following log:

Start importing Assets/iPhone_final_1920x1080.mp4 using Guid(4a6cabe8c82444838bfda281abe35b82) Importer(-1,00000000000000000000000000000000) Error while reading movie: /github/workspace/Assets/iPhone_final_1920x1080.mp4 -> (artifact id: '64692c41f188253627aa45a741fde930') in 0.001871 seconds

MP4 file was added to LFS, if it is important.

How I can get to know what exactly is causing this error? Thank you in advance!

I am aware this is an old post, but this issue still persists so in case anyone stumbles across this, here is the solution. The problem is that Unity does not support .mp4 formats on linux, which you are using as your hosted runner. See video file compatibility for reference. You can fix the issue by converting my .mp4 file into .webm format with vp8 codec. One way to achieve this is using ffmpeg, or directly recording in the desired format. Cheers!

Hi, I'm still seeing this problem, although I'm building for MacOS, not Linux

Hi, I'm also seeing the same issue. I'm wonder how to move over it without changing my movie format. Thanks, Felicia

I'm encountering the same issue where my test project fails to play a video on a raw image component after the app starts, leading to the video being absent during the CICD process. The error log shows:

Start importing Assets/!/Art/Video/Pan Level 1 No Enemies.mp4 using Guid(14fcbdbb56c4bc442ba57afa182f1363) (VideoClipImporter) 

Error: Error while reading movie: /github/workspace/Assets/!/Art/Video/Pan Level 1 No Enemies.mp4.

Game-ci employs Docker images matching the target build platforms (Linux, MacOS, and Windows). The Docker host is Ubuntu, but the actual builds are performed on the appropriate platform-specific Docker images. Given this setup, could the issue still stem from platform-specific video file format support, or is there another potential cause for this error? Any insights or potential solutions would be greatly appreciated.

I was able to work around the issue but it's still not great. The way I did it was to transform my MP4 video into a WEBM (with VP8 codec). I used this command: ffmpeg -i filename.mp4 -c:v libvpx -crf 4 -b:v 20M -an -b:a 64k -vbr on filename.webm

But this causes other issues. Now the video is very ugly when I build for Android (bluish with artifacts). I can't win.

How hard is it to add support for MP4 on the Ubuntu image??

As alternative to transcoding to vp8, the link from https://github.com/game-ci/unity-builder/issues/488#issuecomment-2058890883 says you can place the videos in StreamingAssets and use VideoPlayer instead of VideoClip.
