Transcode issue

[Peter]

The device profile contains limits that can override the performance settings so if you did not modify the device profile prior to changing the performance settings then this value will override them. You can modify the profile using the instructions in the previous post http://forum.conceiva.com/showthread...5592#post35592

It is a problem with network bandwidth rather than a problem with the compatibility of the file with the apple device, the network cannot deliver the file fast enough to the player to allow smooth playback. You could try adding packetsize to the device profile <packetsize live="8192">1024000</packetsize> to see if this helps, see the ConceivaMezzmoAndroid.prf profile for an example of this.

I went back and checked...I have the device profile set at a maxbitrate of 20000000. Device setting under performance tab has maxbitrate 10 Gbps.

Tried adding packetsize suggestion and more less copied the way it was written in ConceivaMezzmoAndroid.prf. Still no improvement.

The video is choppy and turned 90 degrees counterclockwise so viewing it side ways. Audio is there. Double checked on the video in Mezzmo under transcode tab for that video and it is playing original file.

My home network has not changed; essentially running on a 5G /ASUS router. Video I'm trying to play might be 2 minutes long in this case.

As a test, I went back to view an older and even longer video that was created similar, .mov file on iPhone. I chose one that has never given me trouble with playback. Plays audio fine, normal aspect, no 90 deg turn and not choppy. Looking at the file, it did transcode and transcoded as preferred -mov,mp4,mpa,3gp, 3g2, mj2 (-h264-aac). I thought I would run a little test. I took the same video (this latest video created on iPhone) I have been working on with you not playing correctly and forced a transcode identical to the one that plays fine. It did not work. I then for completion went back to the "old .mov movie" that plays fine and tried to use "original file" with it and it came through choppy, turned 90 deg counterclockwise, same as the problem I'm currently having with the new movie.
So I then unchecked "original file" and had it play the transcoded file when I originally loaded it that it has above and it worked like a charm. So now my dilemma is this.
The only difference between those two videos is the time in which they were recorded. It was the same iPhone that recorded the older and the newer video, however an older ios I'm sure. But even if I try to currently use the same transcode for the newest video that worked on the older video, it does not work. That does not make sense.

The transcoding of the newer file might be different because the maxbitrate value has changed in the profile, this can have an impact upon transcoding. Try setting the value back to 2000000 then save the file and after restarting Mezzmo try pre-transcoding it to mp4 again to see if it plays.

I changed the maxbitrate back to 2000000 and tried to pre-transcode to Mp4 the newest video. When doing this, have sound, not choppy, but back to the original problem again of aspect ratio being an issue. Short and stubby picture. Again to test, I went back to the older video that had played correctly and now deleted the mp4 transcode that was done last year and tried to now pre-transcode again fresh. It played fine again. So the older video that has no problems was able to play just fine when pre -transcoded "then and now". But the new video, created supposedly with same format on an apple iPhone, does not want to play correctly when pre-transcoded and give this widened aspect. Again, it would seem that something has changed in the needed profile to transcode .mov files now as compared to then to get them to play correctly.

Looking back at the ffmpeg information of the files you posted earlier in the thread I can see that the file that plays correctly has no aspect ratio specified but the file that has the aspect ratio problem contains a blank aspect ratio. Possibly you can try using the aspect ratio cohttp://www.mezzmo.com/wiki/doku.php?...or_your_videos to see if this fixes it.

ill give it a shot and report back. What does not make sense though is that tonight I basically erased transcoding for both videos and re transcoded today anew. The old plays fine and the new does not. So if they were both identical they should end up I would imagine the same way and they do not.

[Peter]

based upon the ffmpeg information the videos are not identical, something must have changed in the encoder on the phone because the newer file has an empty aspect ratio field.
