I was under the impression that ffmpeg had support for playing an rtjpeg
.nuv videos produced by mythtv. However, when I try playing such a file
using mplayer (which uses ffmpeg for the decoding and specifically notes
its "NuppelVideo/MythTV demuxer and RTJpeg decoder", I get a blank
screen for video (although sound works fine). The same thing happens
with the ffplay decoder included with ffmpeg. Here's the output from
NuppelVideo file format detected.
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 32000 Hz, 2 ch, s16le, 96.0 kbit/9.38% (ratio: 12000->128000)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffnuv] vfm: ffmpeg (NuppelVideo)

AO: [alsa] 48000Hz 2ch s16le (2 bytes per sample)
VDec: vo config request - 480 x 480 (preferred colorspace: Planar YV12)
VDec: using Planar I420 as output csp (no 0)
Movie-Aspect is undefined - no prescaling applied.

alsa-uninit: pcm closed 0.014 ct: -0.012 43/ 43 13% 1% 2.0% 0 0
vlc doesn't even get that far, crashing with a "main decoder error: no
suitable decoder module for fourcc `RJPG'".
The problem occurs on both FC5 and FC6 systems. (On the FC5 system, the
ffmpeg version is 0.4.9-0.23.20060817 from livna.) Am I missing
something (e.g., command line options) here? Is there a way to do this
Barring this, what is the preferred way to view videos downloaded via
Thanks for your help.
