I have downloaded this video http://www.youtube.com/watch?v=CpznCSeqMxw as a flv file. When I now try to play it, mplayer says
Audio: no sound
and shows the video, but no sound (which is, why I have downloaded the video—to have the sound).
And VLC refuses to play it at all. No error message. I am confused.
The file type in Linux:
$ file Space\ Night\ -\ Earth\ Views\ 4-5.flv Space Night - Earth Views 4-5.flv: ISO Media
And some more information from mplayer:
$ mplayer -frames 0 -identify Space\ Night\ -\ Earth\ Views\ 4-5.flv 2> /dev/null | grep -i 'audio\|sound\|video\|clip' ID_VIDEO_ID=0 [lavf] stream 0: video (h264), -vid 0 VIDEO: [H264] 600x480 24bpp 25.000 fps 338.6 kbps (41.3 kbyte/s) Clip info: ID_CLIP_INFO_NAME0=major_brand ID_CLIP_INFO_VALUE0=dash ID_CLIP_INFO_NAME1=minor_version ID_CLIP_INFO_VALUE1=0 ID_CLIP_INFO_NAME2=compatible_brands ID_CLIP_INFO_VALUE2=iso6avc1mp41 ID_CLIP_INFO_NAME3=creation_time ID_CLIP_INFO_VALUE3=2013-07-03 06:36:36 ID_CLIP_INFO_N=4 ID_VIDEO_FORMAT=H264 ID_VIDEO_BITRATE=338576 ID_VIDEO_WIDTH=600 ID_VIDEO_HEIGHT=480 ID_VIDEO_FPS=25.000 ID_VIDEO_ASPECT=0.0000 Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264) ID_VIDEO_CODEC=ffh264 Audio: no sound
Now, what is the reason for this? If I watch it on Youtube it has sound. I don’t think the sound is stripped off during download.
And why isn’t VLC playing the file at all (no video, no sound, it only shows the length of the file, but when I press the play button it stops the playback immediately).
Is somebody able to reproduce this? Or is it just me?
PS: This is the first time this happens. I have already downloaded a lot of videos with DownloadHelper.
