Hi, I have an EyeTV T2 tuner capable of receiving DVB-T2 (Freeview HD) channels in the UK. It is currently connected to a late 2013 iMac. Watching HD channels with EyeTV 3 works fine. Also, if I record a program from one of these channels, the recording plays fine in the EyeTV software, on both the 2013 iMac with NVIDIA GeForce GT 750M graphics card, and on my relatively low powered 2009 MacBook. However, when I export one of these recordings, without re-encoding it, to an .mp4 file, the resulting file does not play very well on either Mac using Quicktime or VLC. The video frame rate is very choppy and the sound stutters. Also, skipping through the exported video is impossible and the video just turns to a grey screen. I have tried to play the exported mp4 files on multiple devices aside from the two Macs including a Samsung Smart TV, a PS3 and a Blu-Ray player and they all have the same problem. I was wondering why the recordings play fine in EyeTV but not when exported? The actual contents of the file, the video codec etc. should not change. Inspecting the exported .mp4 files show that they are 1080p H.264 encoded files with a Mbps of around 4 and with AAC encoded audio. I am sure these files are not too high a bit rate for my equipment to handle. Strangely, if I go to the .eyetv file of the recording and right-click>Show Package Contents, there is a .mpg file inside containing the recording that opens and plays fine in VLC. I was wondering what happens during the export process to inhibit the resulting .mp4 files from playing well? Do these recordings have some kind of digital rights management on them? Another thing I thought it could be is that the exported .mp4 files are somehow lacking a "header"? I remember this used to be a problem with the old .avi container format in that even relatively low bitrate files that should play fine would stutter and play badly if the header was absent. I'd be grateful if anyone could advise me on what I need to do with these files to allow them to play properly, ideally without re-encoding the video as I do not want to lose quality. Many thanks for your help
Hi, I am new here with my first question. If this is already discussed here, please just post the thread. Some days ago we had a sudden grid shutdown and the recording of a serial was interrupted/stopped. I could get a copy of the movie from the broadcasters internet media webpage. Now I replaced the original eyetv movie file inside the ".eyetv" container with this one I have downloaded. Unfortunately eyetv doesn't play the movie (black screen) from the .eyetv-archive file (it plays, if I choose "open quicktime movie...). The downloaded file is a H264 ".mp4" with 25fps. I tried some formats/container with VLC, but had no fortune. Any ideas? Thanks! Mac-Chatter (eyeTV 3.6.x on Mac OSX 10.6.8)
