I've checked

kodi.old.log

Here is what I read

2020-10-19 20:57:47.105 T:1945698320 NOTICE: VideoPlayer::OpenFile: /var/recalboxfs/Videos/movie.avi 2020-10-19 20:57:47.107 T:1584391088 NOTICE: Creating InputStream 2020-10-19 20:57:47.116 T:1584391088 NOTICE: Creating Demuxer 2020-10-19 20:57:47.890 T:1584391088 NOTICE: Opening stream: 0 source: 256 2020-10-19 20:57:47.891 T:1584391088 NOTICE: Creating video codec with codec id: 12 2020-10-19 20:57:47.904 T:1584391088 NOTICE: Creating video thread 2020-10-19 20:57:47.905 T:1681900464 NOTICE: running thread: video_thread 2020-10-19 20:57:47.906 T:1584391088 NOTICE: Opening stream: 1 source: 256 2020-10-19 20:57:47.906 T:1584391088 NOTICE: Finding audio codec for: 86017 2020-10-19 20:57:47.907 T:1584391088 NOTICE: CDVDAudioCodecFFmpeg::Open() Successful opened audio decoder mp3float 2020-10-19 20:57:47.907 T:1584391088 NOTICE: Creating audio thread 2020-10-19 20:57:47.908 T:1552360368 NOTICE: running thread: CVideoPlayerAudio::Process() 2020-10-19 20:57:47.920 T:1552360368 NOTICE: Creating audio stream (codec id: 86017, channels: 2, sample rate: 48000, no pass-through) 2020-10-19 20:57:48.477 T:1681900464 WARNING: CRenderManager::WaitForBuffer - timeout waiting for buffer

At that moment there is nothing left. Now, I know that the film crashed around 9:05 pm.

If I check:

kodi.log

I get:

2020-10-19 21:05:57.625 T:1945636880 NOTICE: Starting Kodi (18.8 (18.8.0) Git:20201015-nogitfound). Platform: Linux ARM 32-bit

This shows that around 21:05 I restarted kodi. The rest of the file shows no error.

I don't know where to look the error for...

ok, thanks ; i'll try that
