Cant play mp4 videos in mythvideo internal player

[paulyche]

I can't play mp4 videos in mythvideo's internal player.

I have a set of videos encoded in mp4 for the ipod and I would like to be able to play these from mythvideo. The files are found by Myth ok, but when played the screen just goes black for a while and then returns to the mythvideo frontend.

the streams returned by ffmpeg -i <filename> are in ffmpeg -formats so I believe the file should play ok.

Any ideas?

I have a similar, or perhaps the same problem as you. I have been using Handbrake in Windows XP to convert my DVDs to an mp4 format that is compatible with quicktime and Linux. I don't know if it was because I updated something in ubuntu, (Mythbuntu 7.10) or if it is because of the Handbrake update, (0.9.2). Some of my mp4 files play in Mplayer and some don't. Actually they are m4v files. Xine and VLC don't play it either. They play no problem in windows MPlayer and windows quicktime.
Try this:
in a terminal window:
mplayer -v <filename>
this should spit out a lot of error messages.
I will post the error message I get when I can to compare.

Which software and version was used to convert to mp4?

Sorry I can't offer a solution :(

I figured out a solution to my problem. I was ripping with ac3 and aac for Apple TV compatibility. and mplayer did not like that. Although there are some ac3+aac files that do play.
I now am ripping from my mythtv box with Handbrake.

Hi molson67,

Any chance that you share the options your using to encode with handbrake.

I've been ripping my hair out for the last few days trying to get mythtv to use Handbrake to transcode my mpeg2 encoded recordings (PVR 500 encoder).

Hi,

I have a similar issue, I pulled some recodings off my mythbuntu box onto another ubuntu desktop, encoded them to mp4, and then when i move them back into my video directory, and try to play them on my mythbuntu box using mythvideo, and i get sound, but no video - just blank screen.

I suspect that its because the codec on my desktop is newer? but i'd prefer to confirm this before i go completely destroying my mytbuntu box. :)

The encoding box was setup using this thread

http://ubuntuforums.org/showthread.php?t=786095

the video was encoded specifically using this command

ffmpeg -y -i input.avi -pass 1 -vcodec libx264 -vpre fastfirstpass -b 1500k -bt 1500k -threads 0 -f mp4 -an /dev/null && ffmpeg -i input.avi -pass 2 -acodec libfaac -ab 128k -ac 2 -vcodec libx264 -vpre hq -b 1500k -bt 1500k -threads 0 -f mp4 output.mp4

The errors i get in the mythbunu log is

Any help you can give would be great - the video quality with the x264 is excellent for a filesize just over 1/10th of the original.

And to add a pinch of strangeness, if i encode it into a Matroska wrapper, it fricken works...
