Transcode issue

[Peter]

You can go to 'Media Devices' and double-click the device in the list then on the Transcoding tab click the button to delete transcoded files and this will remove any transcoded files with the incorrect aspect ratio. Then you can turn off transcoding by unchecking the box to transcode incompatible files so that they can be played on the device.

If you have some files that require transcoding then you can pre-transcode them or you can right-click on one of the iPhone movies that is wider when transcode and select 'Get FFmpeg Information' then either post this here or send it to support [at] conceiva [dot] com and we will send you an updated device profile that will play these files without transcoding.

I'm going to post two separate files below that I'm having trouble with for two reasons. The first, no sound when played on iphone from server. Will play sound to ipad however. The second is one having aspect issues when played back on iphone although created on iphone (issue discussed in previous posts above).

The audio is encoded as mono so this might not be supported by 8Player or this is triggering transcoding on the fly and the bitrate is too high for smooth playback. The aspect ratio issue would be caused by Mezzmo transcoding and not including the metadata 'displaymatrix: rotation of -90.00 degrees' from the file so that the iPhone does not know to rotate the video. Please try going to the properties of the file in Mezzmo and on the Transcoding tab click on Use Original file... to see if it plays the audio without transcoding and if it does then send an email to support [at] conceiva [dot] com and we will send you an updated device profile.

Oddly enough, I had to reboot my computer for another issue and when going back to work on this problem, the first video audio file worked fine then when played on iphone.

However, did a couple of things for the second video. First, followed your advice...went to transcode tab for that video and clicked use original file as "preferred" (by the way for the iphone it showed "original file" and a transcoded file there and both were originally checked). When I tried to play it, it still was wide and then when I went back to file's transcode tab, it showed that both check marks were selected again for the iphone, almost as if I did not unclick the transcode tab first time. So..I then deleted the transcoded option that existed for the iphone listed for that particular movie but when played, was still incorrect. I was curious so I went back to the transcode tab again and out of nowhere, the transcode version appeared for iphone again along with "original" and both options checked. So I then went to "media devices", chose the iphone, edited and unselected the transcode tab there. Went back to the individual movie and made sure "original file" was only selected option, then tried to play and still was incorrect. When going back to the transcode tab once more for the file, it then showed the transcode option again. Not sure what to do at this point.

Again, thanks for your help.

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?
