mobamoba 12 Posted June 4, 2015 Share Posted June 4, 2015 I'm using Chromecast to play back a video and I noticed Emby was transcoding it and I'm trying to figure out why. It's just a 480p mp4. Shouldn't that play on Chromecast natively without transcoding? Is there something odd about this file that is telling Emby to transcode it? Here's the relevant info from my transcoding logs and thanks: {"Type":"Default","Container":"mp4","Size":148395142,"Name":"480P/H264/AAC","RunTimeTicks":9475410000,"ReadAtNativeFramerate":false,"SupportsTranscoding":true,"SupportsDirectStream":true,"SupportsDirectPlay":true,"RequiresOpening":false,"RequiresClosing":false,"VideoType":"VideoFile","MediaStreams":[{"Codec":"h264","Language":"und","IsInterlaced":false,"BitRate":1087917,"BitDepth":8,"RefFrames":4,"IsDefault":true,"IsForced":false,"Height":448,"Width":714,"AverageFrameRate":29.93837,"RealFrameRate":29.97003,"Profile":"Main","Type":"Video","AspectRatio":"17:12","Index":0,"IsExternal":false,"IsTextSubtitleStream":false,"SupportsExternalStream":false,"PixelFormat":"yuv420p","Level":30,"IsAnamorphic":false,"IsCabac":false},{"Codec":"aac","Language":"und","IsInterlaced":false,"ChannelLayout":"stereo","BitRate":159988,"Channels":2,"SampleRate":48000,"IsDefault":true,"IsForced":false,"Profile":"LC","Type":"Audio","Index":1,"IsExternal":false,"IsTextSubtitleStream":false,"SupportsExternalStream":false,"Level":0}],"PlayableStreamFileNames":[],"Formats":["mov","mp4","m4a","3gp","3g2","mj2"],"Bitrate":1252885,"RequiredHttpHeaders":{}} Link to comment Share on other sites More sharing options...
TolkienBard 54 Posted June 4, 2015 Share Posted June 4, 2015 Transcoding will happen when bitrates don't match as well. Link to comment Share on other sites More sharing options...
Luke 37272 Posted June 4, 2015 Share Posted June 4, 2015 that looks like a file that should direct steam, so i'm not sure. as TolkienBard said, could be the bitrate setting. Best thing to do is enable debug logging, try it again and grab the server log. Link to comment Share on other sites More sharing options...
mobamoba 12 Posted June 4, 2015 Author Share Posted June 4, 2015 Okay. I set debugging to enable, restarted the server, and the Chromecasted the same file from before. I've attached the server log and transcoding log from that session. Thanks. server-63569016278.txt transcode-d7661b73-5e38-417a-9285-9241a018c1cd.txt Link to comment Share on other sites More sharing options...
Luke 37272 Posted June 4, 2015 Share Posted June 4, 2015 For this file it's due to the Cabac value but i'm going to remove that check. It will be resolved with the next release of the server. 1 Link to comment Share on other sites More sharing options...
