Adding outro video to multiple video files using ffmpeg
31 août 2017, par jasanI can successfully merge files using the following command using ffmpeg :
ffmpeg -f concat -i mylist.txt -c copy output.mp4
the mylist.txt looks like this :
file './video.mp4'
file './outro.mp4'However what I want to do is the following :
-
I have 100 video files ( video1.mp4, video2.mp4, video3.mp4,...)
-
i have one outro file(outro.mp4)
I want to concat outro.mp4 to the end of each of the 100 files and save each of concatenated video file with the same filename as the original videofile( i.e video1, video2....)
I’m on a windows machine. any way I can achieve this ? code snippet would be really helpful.

Video playing, how to play a video back a a rapid rate at random timestamp locations
10 avril 2020, par Zarc RowdenNote : this is a mildly general question that is looking more for pointers in the right direction and not exactly requiring a concise coded answer. I appreciate any and all input, thank you for lending your brain power to me for this moment :)



I have a script that receives midi messages in real time and triggers playback of a single video on various timestamps that are changed/selected regularly and randomly by a user. Currently this is working in the browser, however, I've realized that there is some noticeable latency between (i'm guessing the cause here so please correct me) the moment a request to play a video at a specific time is made(note : the video is not being requested over the wire, this action does not take place until a JS Blob Url is loaded into the player) and the moment where that request is fulfilled and delivered from storage to pixels on the screen.



My question is : Is it reasonable to assume that there is a tool out there, that given the correct video format and optimizations both in the code and in the file that could load an entire, say : 1 gb video into memory and play it back at random timestamps every 60 milliseconds at completely random, constantly changing timestamps.



If you're now all the way down here... Thanks for reading this far, or scanning ! Please let me know if this question makes any sense / could be improved, I'm happy to clarify further.

FFMPEG reports invalid video resolution, video headers container seem to be different from actual frames !
20 décembre 2011, par EmilianoQuick question, i have a movie, which was cut and rendered with Sony Vegas from its original format to a .wmv file. Here comes the tricky part, movie when played, either with
VLC
orWMP
, has a resolution of 656x480 ... BUT when i run a ffmpeg -i on it, it says it has a resolution of600x480
....I took the time of actually capturing a frame and croping it with photoshop and its
656
and not600
like ffmpeg its reporting, why would this could be happening ? How could i fix the headers resolution ? Would that have any impact on video re-rendering ? As i said, VLC and WMP seems not to care about the incorrect headers and are playing it right, BUT, jwplayer seems to be using the header information, which i don't blame him, its correct to do that, but why the video headers could be wrong ?ffmpeg -i trailer.wmv
Input #0, asf, from 'trailer.wmv' : Duration : 00:01:04.93, start : 3.000000, bitrate : 2144 kb/s Stream #0.0 : Audio : wmav2, 44100 Hz, mono, 32 kb/s Stream #0.1 : Video : wmv3, yuv420p, 600x480 [PAR 59:54 DAR 295:216], 2065 kb/ s, 25.00 tb(r)
And yeah, the
PAR/DAR
parameters are also wrong, but honestly, i don't understand that technical shit, usually watch video and make sure it look good, any feedback would be appreciated :PIs there a way to change the container information with ffmpeg so applications that actually do use the container information don't render video incorrectly ?
