 |
|
Hi, I'm testing pymedia but when I try the dump_video.py example doesn't work
| Code: |
$ ./a.py Video03266.mpg xxx 2
Traceback (most recent call last):
File "./a.py", line 48, in ?
dumpVideo( sys.argv[ 1 ], sys.argv[ 2 ], int( sys.argv[ 3 ] ) )
File "./a.py", line 16, in dumpVideo
raise "There is no video stream in a file %s" % inFile
There is no video stream in a file Video03266.mpg
|
any idea? |

Which pymedia version is that ?
Something wrong either with the file or with the example. Can you share the file ? |

I'm using pymedia-1.2.2.1
I hasn't installed OGG, VORBIS, FAAD, MP3LAME and VORBISENC
the code:
| Code: |
#! /bin/env python
import sys, os
import pymedia.video.muxer as muxer
import pymedia.video.vcodec as vcodec
import Image
def dumpVideo( inFile, outFilePattern, fmt ):
dm= muxer.Demuxer( inFile.split( '.' )[ -1 ] )
i= 1
f= open( inFile, 'rb' )
s= f.read( 400000 )
r= dm.parse( s )
print
v= filter( lambda x: x[ 'type' ]== muxer.CODEC_TYPE_VIDEO, dm.streams )
if len( v )== 0:
raise "There is no video stream in a file %s" % inFile
v_id= v[ 0 ][ 'index' ]
print "Assume video stream at %d index: " % v_id
c= vcodec.Decoder( dm.streams[ v_id ] )
while len( s )> 0:
for fr in r:
if fr[ 0 ]== v_id:
d= c.decode( fr[ 1 ] )
# Save file as RGB BMP
if d:
dd= d.convert( fmt )
img= Image.fromstring("RGB", dd.data, dd.size)
Image.save(outFilePattern % i, img )
i+= 1
s= f.read( 400000 )
r= dm.parse( s )
print 'Saved %d frames' % i
# ----------------------------------------------------------------------------------
# Dump the whole video file into the regular BMP images in the directory and file name specified
# http://pymedia.org/
if __name__ == "__main__":
if len( sys.argv )!= 4:
print 'Usage: dump_video <file_name> <image_pattern> <format_number>\n<format_number> can be: RGB= 2'+\
'\n<image_patter> should include %d in the name. ex. test_%d.bmp.'+ \
'\nThe resulting image will be in a bmp format'
else:
dumpVideo( sys.argv[ 1 ], sys.argv[ 2 ], int( sys.argv[ 3 ] ) )

Assume video stream at 0 index:
Traceback (most recent call last):
File "./a.py", line 53, in ?
dumpVideo( sys.argv[ 1 ], sys.argv[ 2 ], int( sys.argv[ 3 ] ) )
File "./a.py", line 34, in dumpVideo
dd= d.convert( fmt )
AttributeError: 'VFrame' object has no attribute 'convert' |
