I am stuck at a very weird and complex problem, hoping if anyone know the solution:
I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it's screen either show loading icon or black screen while audio is working fine.
I am using following codec:
['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']
I work on linux and using html5 player on my website. I am converting video in mp4 format.
Input:
ffmpeg -i /<server path>/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path>/testing.mp4

When trying to convert a .webm video (two colored animation) to a .mp4 video using ffmpeg (3.4.2 on mac) the result is somewhat blurry. I did research this topic and tried different approaches to solve this. Here is the most promising command:
ffmpeg -i vidoe.webm -qscale 1 video.mp4
However, the quality change is still tremendous, see the difference below.
webm
mp4
The resolution of the two videos is the same, however the size dropped from 24,3MB (.webm) to 1,5MB (.mp4) after conversion.
Update
Here is the log of the conversion.

Any idea on how to overcome this quality loss?
Changing -qscale 1 to -crf 1 resolves the quality issue. The working command is:
ffmpeg -i video.webm -crf 1 -c:v libx264 video.mp4
As outlined in the H.264 Video Encoding Guide -crf takes in values from 0 (lossless) to 51 (worst quality).
I'm trying to insert 13 seconds of black video at the start of a video that has sound using ffmpeg like so:
ffmpeg -f lavfi -i "color=c=black:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
"[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \
[blackstart] [1:v] concat=n=2:v=1:a=0[out]" \
-map "[out]" -c:a copy output.mp4
However the sound is not being maintained. What am I doing incorrectly? -c:a copy does not seem to work should I be using a [1:a] somewhere?
garrett-retina:~ garrett-macbookretina$ ffmpeg -f lavfi -i "color=c=red:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
> "[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \

You need to add silent audio as well. One method using anullsrc:
ffmpeg \
-f lavfi -i "color=c=black:s=720x406:r=25:sar=1/1:d=13" \
-f lavfi -t 1 -i anullsrc=cl=stereo:r=16000 \
-i input.mp4 \
-filter_complex \
"[2:v]setpts=PTS-STARTPTS[video]; \
[0:v][1:a][video][2:a]concat=n=2:v=1:a=1[v][a]" \
-map "[v]" -map "[a]" output.mp4
The silent audio duration only needs to be shorter than the black video duration; the concat filter will pad the rest automatically.
I'm unable to test this example at the moment, but if it is broken let me know and I can fix it later.
I'm doing some extreme slow motion in ffmpeg on a video, both video and audio track, but can't quite get my calculations correct.
The input video is 00:06:41:00 at 24fps (9624 frames).
I need the output video to be 34:00:00:00 at 24fps (2937600 frames).
I tried these for the video and audio:
setpts=305.237*PTS
atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.807668329177057
However the video overshoots by 00:01:19:08 and the audio I'm unsure, on one player it stops somewhere around 8 hours but on another it just continues. What are the correct formulas?
Also on VLC the video has grey frames between video frames - do I need to interpolate to have continuous video frames?

But I get a video with no audio in QuickTime. I think its a problem of the output container (mp4) not supporting mp3. What output container might be best? Due to quality loss, I am reluctant to convert the mp3 to another format. If my audio is mp3, what might I change about this ffmpeg command?
The final destination is YouTube.
Because YouTube is the final location you can ignore the other players:
Most non-FFmpeg based players can't decode yuvj444p. If you want the video in these other players to work, then add -pix_fmt yuv420p as an output option as mentioned in the console output.
Some players have trouble decoding MP3 in MP4 such as QuickTime and WMP with certain audio rates. If you need it to work in these players you'll need to re-encode to AAC audio by changing -c:a copy to -c:a aac.
Since the input is a single image you can reduce your frame rate for a much faster encoding by adding -framerate 1 as an input option. Again, some players may not be able to decode this frame rate.
YouTube can handle these potential issues, so feel free to upload it. See FFmpeg Wiki: YouTube for more info.
This question already has an answer here:
FFmpeg converting image sequence to video results in blank video [closed]
(1 answer)
Closed 5 years ago.
My current project involves creating a .flv using AIR (using https://github.com/zeropointnine/leelib/tree/master/src/leelib/util/flvEncoder) - which then has to be converted into an .mp4, for which we are using ffmpeg.
The .mp4 output is the correct dimensions and duration, but blank (no images). Audio is not an issue as the original output has no audio.

Any ideas?
See the informational message:
No pixel format specified, yuv444p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.
So, add -pix_fmt yuv420p and you should be fine.
