When I concat my videos I have this message :[output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
perhaps it is not related
I don't know ...Here my concat command and execution log

Converting DVD image with subtitles to MKV using avconv
16 janvier 2016, par Carlos Eugenio Thompson PinzónThis is the procedure I know to convert a DVD image to another videoformat (v.g. MP4) :
- concatenate the
VTS_01_n.VOBfiles insideVIDEO_TSfolder (for n >= 0) into a single VOB file. - use
avconvorffmpegin order to convert that VOB into another format.
So far so good, however now I want to convert the DVD image with the subtitles. As far as I know the MKV format supports subtitles, so it seems an obvious choice. Alternatively I might use any other format with hard subtitles (subtitles as part of the video image).
However, the subtitle encoding in the DVD image is
dvdsuband I get the following errorOnly SUBTITLE_ASS type supported.
Subtitle encoding failedHowever, when running
avconv -codecsI get :...
DES dvdsub DVD subtitles
...And the
-c:s copyswitch, while it prevents the command to fail, it does not seem to produce a subtitle that the player can understand.So, how can I create
asssubtitles fromdvdsubusingavconv?My VOB file has eight subtitle channels and two audio channels. The Ubuntu video app does not show any subtitles, and only the first audio channel seems to be working, do the DVD image might be broken.
Another file, for a double-layer DVD, displays the Subtitle encoding error, however when using the
-c:s copyswitch it further displays :Application provided invalid, non monotonically increasing dts to muxer in stream 2: 49 >= 49
av_interleaved_write_frame(): Invalid argumentThank you in advance for any ideas on how to solve these problems.
(I am using Ubuntu where
ffmpegis an alias foravconv. I know it is possible to install the real ffmpeg but so far I have not done so.)

Audio & Video not synchronized properly if i merged more videos in mp4parser
1er octobre 2013, par maniyaI have used mp4parser for merging video with dynamic pause and record video capture for max 6 second recording. In preview its working fine when recorded video with minimum pause/record, If i tried with more than 3 pause/record mean the last video file not get merged properly with audio.At the start of the video the sync is ok but at the end the video hanged and audio playing in screen for the remaining file duration about 1sec.
