Transcode issue

**Peter** · 02-22-2017, 10:16 AM

When you try to play the file on the iPhone if you don't refresh the listing then the URL will still have the information set to transcode the file. If the app you are using caches the listing then you may need to exit the app and then restart it and browse to the file so that the URL for the original file is used.

I'll give that a try and report back.

Okay, today closed the Mezzmo app on phone the way to close all apps for iphone so as to not have that cached data an issue. In Mezzmo on server, made sure for that one video, all transcodes under transcode app was cleared out and closed. Went back in to ensure that happened and it did. clicked then on "use original file" and ascribed that to the iphone. Went to media devices to make sure that the iphone was not going to be able to transcribe. The video still played wide. I then went to the video transcribe button and once again both a transcoded file and the original file had reappeared and were both clicked. I'm not sure what else I could have done in this case.

Alright, feel dumb... but I may have solved some of this. Checked my IP address in iphone to make sure it did not change and it had. So when I was trying to make changes to the video file in Mezzmo under transcode tab for what I thought was the correct media device, it was not taking it because it was not the actual device's IP so figured that out. I'm not sure why that randomly changed since that was the LAN assigned from the WIFI router and does not ever seem to change.
Now, I was able to get the videos in question playing wide aspect to work with "original file" as expected. So...

I have numerous .MOV files and some play wide and some do not. Would you recommend I delete all transcoded files for this iphone device and start over? Also, If I leave my iphone setting under media devices - transcode - to not transcribe files, will it then start to have trouble playing other files I have (ie MTS and MP4). Would it be best to go into each individual .MOV file that is playing wide and tell it to play "original file" vs delete all transcode files?

I would recommend deleting all transcoded files for the iPhone then edit the device profile to remove the maxbitrate setting from the mp4 container, it is currently set to 2000000 so this is forcing your files to be transcoded because they are over this limit.

You will need to:
1. Open Mezzmo and stop your Mezzmo media server, then exit Mezzmo
2. Go to your device profiles folder (see this thread for its location: http://forum.conceiva.com/showthread...ofiles-located) and edit the MariiaSmeshkova8player.prf file in a text editor and look for <maxbitrate>2000000</maxbitrate> in the mp4 container then delete this text or set the limit to 20000000 and save the file
3. Open Mezzmo and start your Mezzmo media server

I am sorry to revive this problem but still gives me trouble. Bear in mind I have done the above and did not see a difference. I have noticed two things:

1. When I use the original file, it is Rotated 90 degrees counterclockwise, has audio, and is delayed/ choppy playback.
2. If I let Mezzmo transcode this, it leaves a wide aspect, no audio but plays much faster.

All of these are .mov files created on an iPhone and utilizing 8player as app to play back on Apple devices (ie Iphones, Ipads, and Apple TV).

Please go to 'Media Devices' and double-click the device in the list and on the Performance tab set the maximum bitrate to a very high value so that it will not get hit and trigger transcoding. The iPhone will record the video with a very high bitrate so streaming this file from the Mezzmo server to the device over wifi may be too slow and this is why transcoding to a lower bitrate improves playback, the problem is that transcoding is changing the container to mpegts which results in 8Player displaying the aspect ratio differently and uses mp2 audio which does not appear to be supported by 8Player anymore. As a test you could try editing the profile to turn off encoding for mpegts:

<avcontainer id="mpegts" name="mpegts" mimetype="video/mpeg" encode="0" supportschunked="0" >

and set matroska as the default format:

<avcontainer id="matroska" name="matroska,webm" mimetype="video/x-matroska" encode="1" format="matroska" supportschunked="0" level="30" preferredtranscoded="1">

Tried changing under performance tab setting to from 100 Mbps to 10 Gbps and did not see a change. Did not try to transcode but then again I had the tab for that device unclicked for transcoding. So in a sense I forced the original but then got the 90 deg counterclockwise picture with normal aspect and sound. Was also still quite choppy and not viewable.

When I went in and changed profile settings as you have listed, did same thing.

As a separate but related issue, went back into devices by double clicking - transcode tab- then checked "transcode incompatible..." but changing the performance speed did not cause it to utilize the original file.
