FFmpeg Time Skipping after concat
18 septembre 2017, par Manul Hüttingeri am trying to concatenate videos and in my resulting Videos i have the issue that at the concat edges my video is skipping/glitching.
General Workflow
in general my workflow looks like this
- Stream via ffmpeg
- capture stream and segment all 2 mins in to TS files
- concat TS file to MP4 video
- cut MP4 video at the desired Timestamps
Detailed Look at Step 4
as i am handling 2-hours+ videos i don’t want to re-encode the whole video. So i am looking for the closest I Frames to my In and Outpoint and cut 1 Frame before/after. As my result i get 3 Videos (front/middle/back). Now it is only needed to re-encode front and back and concat all three Videos.
So far the theoryGeneral Observations
As i look at my resulting video, i obeservated the following.
frontpart duration is e.g. 3.2 secs. i skip framewise through the Video and get nice and clean timestamps ( 00:00:02.620, 00:00:02:660 )
As soon as i get to my cutting edge the timestamps are skipping some frames and changing (00:00:03.200, 00:00:03.408 ,00:00:03.409). When i look only at the single frame images, their are no missing/dropped frameswhen i concat my TS files, the results contains a messed up frame rate e.g from constant 25 F/s to 25.0096 F/s

Cutting with ffmpeg a video (recorded with Kodi) gives no image
1er octobre 2017, par LaureI am trying to cut videos I get from a IPTV add-on in Kodi. The original video can be watched with VLC, Mplayer, xine, etc, but after being copied there is no image. According to mediainfo there is a video stream but nothing can be seen. The command I use is :
ffmpeg -y -i test-1.mpeg -scodec copy -vcodec copy -c:a copy -map 0 -ss 00:00:10.000 -t 00:00:10.000 test-1-cut.mpegI suppose there is something wrong with the original videos recorded by Kodi, but they give no problem with any player. A short example video is this one :
https://drive.google.com/open?id=0B0WC80aT-4WrSDNENzhxRUxkOXc
The output with the -report option is this one :

I know this should work since the exact line does work for other files. But the result with these is a silent video.
I checked the audio file being used and it seemed fine when played. but I did get a weird warning when creating it. Basically I have 2 audio tracks, one is overlay music and the other is talking. I create the combined audio with this command.
ffmpeg -y -i /var/www/temp/audioTrack.mp3 -i /var/www/temp/musicTrack.mp3 -filter_complex amerge -c:a libmp3lame -q:a 4 /var/www/temp/combined.mp3Here is the output from the second command.

The Music and Audio tracks are created with AudioSegment in python from the pydub library. I’ve used this before with no issues. The code for this is as follows.
sound = AudioSegment.from_mp3(audio)
introSilence = AudioSegment.silent(duration=introLength)
creditsSilence = AudioSegment.silent(duration=creditsLength)
increasedAudio = sound + 12
talking = introSilence + increasedAudio + creditsSilence
talking.export(audioTrack, format="mp3")

introMusic = mus[ : introLength]
videoMusic = mus[introLength - crossFade : introLength + videoLength + crossFade]
creditsMusic = mus[totalLength - creditsLength : totalLength]
lowerMusic = videoMusic - 6
totalMusic = introMusic.append(lowerMusic, crossfade=crossFade).append(creditsMusic, crossfade=crossFade).fade_out(fadeOut)
