FFmpeg recording works on one laptop but not the other
30 novembre 2019, par Jason TThe following command :
ffmpeg -f dshow -framerate 30 -video_size 640x480 -i video="HD Pro Webcam C920" out.mp4works on one laptop (with C920 LogiTech camera) (Im calling it GOOD LAPTOP). It outputs a recorded video. But it will fail on another laptop (called BAD LAPTOP) and by fail on another I mean - it doesnt output a video (see below for output).
The suggestions are to change parameters based on the specific error that occur on BAD LAPTOP. I have tried many different suggestions but they dont seem to work. Furthermore, they dont provide much insight into the underlying cause of the problem.
Ive used the same camera on both laptops. Im using static windows binaries downloaded from FFmpeg web-site (veranoe). Please note the versions used below were different but that doesnt appear to matter.
Trying to diagnose. Anyone have an idea of where the problem may lie. It seems to indicate a problem at the level of the system / camera setup.
Please note that I’ve updated BAD LAPTOP but still no dice. Also please note that Ive tried this on several systems already and it seems to run ok (i.e., produce an output video)
BAD LAPTOP :
$ ffmpeg -y -f dshow -framerate 30 -video_size 640x480 -t 10 -i video="HD Pro Webcam C920" out.mp4

Now im adding third subtitle and i get this warning :

Playing back the file with VLC i can see that Finish subtitles (between 21:33 and 22:16) are not showing up.Dumping packets from 0:3 track i see that 4 packets have the same DTS/PTS values.

Make!Sometimes muxing subtitles in different order (for example Finish before Danish and then Swedish) would solve this problem, but i would like to know why such things are happening.

MP3 files created using FFmpeg are not starting playback in browser immediately. Is there any major difference between FFmpeg and AVCONV ?
23 janvier 2019, par AR5I am working on a website that streams music. We recently changed server from Debian (with avconv) to a Centos7 (with FFmpeg) server.
The mp3 files created on Debian server start playback on browser (I have tested Chrome and Firefox) start almost at the same time they start loading into the browser (I used Network tab on Developer Tools to monitor this)Now after the switch to Centos/FFmpeg server, the files being created on this new server are displaying a strange behavior. They only start playback after about 1MB is loaded into the browser.
I have used identical settings for converting original file into MP3 in both AVCONV and FFmpeg but the files created using FFmpeg are showing this issue. Is there something that might be causing such an issue ? Are there differences in terms of audio conversion between AVCONV and FFmpeg ?
I have already tried
I first found that the files created on old server (Debian/Avconv) were VBR (variable bitrate) and the ones created on new server were CBR (constant bitrate), so I tried switching to VBR but the issue still persisted.
I checked the mp3 files using MediaInfo app and there seems to be no difference between the files.
I also checked if both files were being served as 206 Partial Content and they both are indeed.
I am trying to create mp3 files using FFmpeg that work exactly like the ones created before using avconv
I am trying to make the streaming site work on the new server but the mp3 files created using FFmpeg are not playing back correctly as compared to the ones created on the old server. I am trying to figure out what I might be doing wrong ? or if there is a difference between avconv and FFmpeg that is causing this issue.
I am really stuck on this issue, any help will be really appreciated.
Edit
I don’t have access to old server anymore so I couldn’t retrieve the log output of avconv. The command that I was using was as follows :
avconv -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"Here is the command and log output from new server :
ffmpeg -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"
