Why can I play one movie in MPMoviePlayer but not an other movie? -


i have implemented mpmovieplayer in app , when try sample video in .mov format works well. when change movie-clip .mp4 or m4v not work, app crashes (i have tried bunch of different movie-files. can wrong? else have problem?

i don't know if answers question, did quick search on supported file formats.

another s.o. answer:

supported formats class supports movie or audio files play correctly on ipod or iphone. includes both streamed content , fixed-length files. movie files, typically means files extensions .mov, .mp4,.mpv, , .3gp , using 1 of following compression standards: 1. h.264 baseline profile level 3.0 video, 640 x 480 @ 30 fps. (the baseline profile not support b frames.) 2. mpeg-4 part 2 video (simple profile) if use class play audio files, displays white screen quicktime logo while audio plays. audio files, class supports aac-lc audio @ 48 khz, , mp3 (mpeg-1 audio layer 3) 48 khz, stereo audio.

so guess why :) coulndt convert mov ?
