Until I go to 10.04, I'm ripping the pcm with mplayer: mplayer -vc dummy -vo null -ao pcm:file=test.wav MVI_0054.MOV
-- Videos with uncompressed PCM audio don't play sound properly https://bugs.launchpad.net/bugs/572020 You received this bug notification because you are a member of OpenShot Developers, which is subscribed to OpenShot Video Editor. Status in OpenShot Video Editor: Won't Fix Bug description: I am using openshot-1.1.3-karmic1 on Ubuntu 9.10, installed from PPA. I also have melt-0.4.4-2build1 installed. I am trying to edit videos created by my Canon EOS Rebel T2i (aka 550D and Kiss X4). This camera uses a .mov file format using h.264 video with uncompressed PCM audio. When I try to play the video in OpenShot, audio is only output for a fraction of a second. Sound works correctly when I play files using "ffplay". Sound fails after a fraction of a second when I play files with "melt". Here's what "ffmpeg -i" says when I point it at one of my files: Seems stream 0 codec frame rate differs from container frame rate: 59.94 (60000/1001) -> 29.97 (30000/1001) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'mvi_0272.mov': Duration: 00:00:16.54, start: 0.000000, bitrate: 47683 kb/s Stream #0.0(eng): Video: h264, yuv420p, 1920x1080, 29.97 tbr, 29.97 tbn, 59.94 tbc Stream #0.1(eng): Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s At least one output file must be specified For the moment, it appears I will be able to get around this by transcoding audio in the files (from PCM to AC3) with a command similar to this: ffmpeg -i input.mov -vcodec copy -acodec ac3 -ab 384k output.mov I'll try to upload an attachment, a few seconds of 640x480 video. The audio is just fan noise. _______________________________________________ Mailing list: https://launchpad.net/~openshot.developers Post to : [email protected] Unsubscribe : https://launchpad.net/~openshot.developers More help : https://help.launchpad.net/ListHelp
