To make the story short, I just want to create a video from a X number of images and a mp3 file, AND get the same audio quality.I’ve checked the ffmpeg website, but … here is what I’ve got:ffmpeg.exe -y -i img%01d.jpg -i “03 eminem – when I’m Gone.mp3” -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest shortt.mp4Where: In the same folder I have img0.jpg img1.jpg and so on …The mp3 file is the audio file.The output should be stored in shortt.mp4After I’ve runned this command, it t

I generated 2 mp4 files – a 5 second intro file which is created by the script below and the main video about 1 minute long is created by screen-cast-omatic both in mp4 format. When I attempt to concat using the “ffmpeg -f concat -i mylist.txt -c copy output” method, it produces an output file where the intro file plays fine. Then the main video plays; the audio is fine but the video is messed up where it displays garbled video on top.Using the “ffmpeg -i “concat:input1.mpg|input2.mpg|input3.mp

I’m attempting to use ffmpeg to transcode an input video from whatever format it’s in to an mp4 with h.264 video and MP3 audio and have the output go directly to FMS 4.5 using rtmp so the video will stream right after being transcoded.

ffmpeg video-conversion ubuntu-12.04 video-encoding libav
I am using the version of avconv in Ubuntu 12.04 to archive videos. I would preferably use some kind of lossless video compression (e.g., huffyuv or FFV1), but using the original video stream (copy codec) would also be acceptable. Unfortunately, with any of these options the output file (mkv containing only the video in whatever format) is much larger than the input file (vob containing video, audio, and subtitles). I could understand if the lossless compression just did a horrible job on my par

I recorded a bunch of 1680 x 1050 (16:10 aspect ratio) videos, and I want to merge them into a single video.I’ve been using Windows Live Movie Maker, but this only supports two aspect ratios: 16:9 and 4:3. Neither of these are what I want. They both result in black bars appearing (either left/right or top/bottom). Is there a way to output video at 16:10 aspect ratio using Windows Live Movie Maker?If the answer is “No”, then how can I accomplish this task using some other software that runs on Wi

video video-conversion
My set top box recorded some TV shows in a dvr-ms and mpeg format, both of which have aspect ratios changing on the fly according to the change of aspect ratio of the currently broadcasted/recorded media (for example the show I wanted to record has 4/3, while the ads broadcasted with it are in 16/10). I need to convert either dvr-ms or MPEG2 video to something more standard, lets say avi/xvid or mp4/x264 or similar with aspect ratio of 4/3 throughout the entire video, which furthermore consists

I’ve recovered some files from an hdd that weren’t supposed to be deleted in the first place, but they have seeking problems/crash the players. Since they have the right size, I’m thinking it might be a problem of corrupt index/header, so I’m trying to find a way to fix them. It’s easy to find examples on how to fix corrupt .avi files with mencoder, but .wmv seems trickier.Also, I realize there might not be a way to fix these files, but I figure I might as well as try.

I’ve been searching on the web for tools (online and desktop) to convert SWF files to WMV. We don’t have the original FLA files anymore, and these SWF contain how-to software instructions. Some tools I’ve tried: MediaCoder, Format Factory, SWF Decompiler (kept freezing up), and File Wiggler (online tool). They either crashed or couldn’t handle SWF-to-WMV conversion. Anyone know of a good, free tool for this task on Windows 7? Thanks.

compression video-conversion quicktime
I have a 40 minute, 6 gigabyte .MOV file that I transferred from my iPhone to my PC. I need to upload the video to Youtube but the file is too large. When I try to compress the video, my computer will shut off when the process reaches 3 or 4 percent. This has happened in Windows Live Movie Maker, Riva FLV encoder, and VLC. Any ideas on how I can get this file down to a reasonable size so I can upload it online?

I recently got a USB TV Tuner card. I want to digitize old family VHS tapes. However the TV Tuner card driver doesn’t do audio, only video. I have plugged a 3½mm jack from the video machine my laptop. The video from the VHS presents as a v4l device, like a webcam. I can watch video (w/ audio) fine. I tried writing some gstreamer commands to record from the video, and it was sort of working, but eventually the audio would get out of sync.So is there any application on/for Ubuntu that makes it eas

I have movie files of format *.mpg. When I try to play these files with my DVD player, in TV the picture size shows up very small compared to TV size, the picture is aligned in the center with size of some 6 X 7 inches.. This is certain I guess, because TV knows to display pixel ration that is defined it cannot maximize the size by itself.. while if I play it in desktop .. in some media players like vlc, kodec player..

ffmpeg mythtv mp4 video-conversion
I am trying to convert mythtv recorded mpg (mpeg2) files into streamable mp4 files. Converting to an mp4 is simple, however, the entire file must be converted first before it is usable. Even using conversion tools that put the “mov atom” at the start of the file for quick streaming require that the entire mp4 be encoded before that happens.I read on avconv docs that “The mov/mp4/ismv muxer supports fragmentation.” which can put a “fake” mov atom at the start of the file and then puts a new one

Using h264 and aac, I’ve been trying to generate an mp4 and mpegts output in one command using the new tee muxer.Either it complains about a lack of the aac_adtstoasc bsf, or if global_header is set a lack of the h264_mp4toannexb bsf. However, I can find no way to add a bsf for one output and not the other: adding it as usual applies to both outputs, and the muxer options (between []) do not accept bsfs.Did the ffmpeg team a) document this feature poorly or b) render this combination of outputs
