Hi, folks,
I downloaded a video file from YouTube which makes my players hang.
VLC neither plays audio or video but just remains as if no file was in the playlist (in fact it is).
When I start vlc (vlc -v) from console and try to play that video file vlc writes to the console
mp4 stream warning: unknown box type tft (incompletely loaded)
When I feed Google with this message I receive just similar results ('tft' seems to be individual to my problem) but not a solution.
******************
When I try to play the file with GNOME Mplayer it works but without the sound. I already checked in the preferences that I don't use the internal volume control of Mplayer.
Does anyone have a hint for me ? I am unsure if a codec is missing because VLC would tell me that ?!?
As Mplayer can decode the images I think the file is not corrupted. But what about the sound ?
********************
The video file is located here: http://www.youtube.com/watch?v=30ifeJZSQ64 (480p, file size is approx. 415 MByte)
I downloaded it with this Firefox extension: http://www.downloadhelper.net/
output vlc: http://pastebin.com/mhYDeGK4 output GNOME Mplayer: http://pastebin.com/yp6U6w9d
Thanks in advance, Nelson.
I cannot find the 480p MP4 version. I get: $ youtube-dl -F http://www.youtube.com/watch?v=30ifeJZSQ64 Available formats: 35 : flv [480x854] 44 : webm [480x854] 34 : flv [360x640] 18 : mp4 [360x640] 43 : webm [360x640] 5 : flv [240x400] 17 : mp4 [144x176] I tried downloading the format 18 and the 44 and they both play fine in my machine. About your gnome-mplayer log, the curious thing is that is doesn't detect any audio stream at all. I'm using mplayer2, and I get all the audio information without problem: $ mplayer --identify --frames=0 video.mp4 ... ID_AUDIO_ID=0 ID_AID_0_LANG=und [lavf] stream 1: audio (aac), -aid 0, -alang und ... And about your VLC log, I think that more relevant than the "unknown box type tft" are the lines: 5. [0xb6a062e8] mp4 stream warning: unknown box type sidx (incompletely loaded) 6. 7. [about 200 times the line above] My guess is that your file is simply corrupted. You can try downloading it again, but my advice is to use the excellent tool "youtube-dl". -- Rodrigo
