avconv with subprocess
17 juillet 2012, par Niclas NilssonIt's seems like I never really manage to wrap my head around subprocess. This commandline works in bash
avconv -i "concat:/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment0.ts|/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment1.ts" -vcodec copy -acodec copy /tmp/test1.tsBu if I try this :
cmdline = ['avconv', '-i "concat:/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment0.ts|/tmp/BABAR_AND_THE_A-011A-hts-a-v1-cc3651d01841d748_Layer6/6148_Period1/segment1.ts"', '-vcodec copy', '-acodec copy', '/tmp/test1.ts']
subprocess.call(cmdline)It exit avconv with the following error :

1I've tried some variants (including shell=True) but I can't figure out the problem.
Update
Cjb made an answer that really worked. But my real code is more complicated. I believe it's hard to get something out of it. But I throw it in here just in case there is an obvoius problem that I missed.
def run_avconv(output_dir, fnames):
full_fnames = [os.path.join(output_dir, fname.replace('\n', ''))
for fname in fnames]
concatted_files = '|'.join(full_fnames)
cmd_line = [AVCONV_CMD,
'-i',
'"concat:' + concatted_files + '"',
'-vcodec',
'copy',
'-acodec',
'copy',
os.path.join(output_dir, 'out.ts')]
subprocess.Popen(cmd_line)the full_fnames variable is :

Encoding for HLS using FFMPEG results in have a decreasing DTS
29 décembre 2014, par Luuk D. JansenI am trying to encode video for HTS live streaming, but am having problems with validating the stream using Apple Media Validator (mediastreamvalidator).
(my test file : http://dominicansinteractive.idoms.org/media/9536/playlist.m3u8)The output is :
--------------------------------------------------------------------------------
http://dominicansinteractive.idoms.org/media/9536/199/prog_index.m3u8
--------------------------------------------------------------------------------
Playlist Validation:
OK
Segments:
segment_00000.ts:
ERROR: (-1) Decreasing DTS were detected in track 0

Average segment duration: 8.07 seconds
Average segment bitrate: 2155094.67 bps
Average segment structural overhead: 206525.83 bps (9.58 %)
The second segment doesn’t seem to have the problem :

This seems to be a serious problem for HLS, so I am looking if there is a way to fix this.
When looking with FFMPEG at the encoded file I get (encoder output/command at the bottom of the email) :

Extract Video Frames In Python
22 avril 2017, par TheNoneI want to extract video frames and save them as image.
import os, sys
from PIL import Image
a, b, c = os.popen3("ffmpeg -i test.avi")
out = c.read()
dp = out.index("Duration: ")
duration = out[dp+10:dp+out[dp:].index(",")]
hh, mm, ss = map(float, duration.split(":"))
total = (hh*60 + mm)*60 + ss
for i in xrange(9):
t = (i + 1) * total / 10
os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))But I have this error :

Note, the names of encoders and decoders dont always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported for example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats its even
worseWhat is wrong in my code ? Thanks in advance
