  ffmpeg is giving me an error and I couldn't get much help googling it, besides a thread on ffmpeg mailing list dated 5 years ago which doesn't address the exact same problem.

  Videos which don't play in Firefox: How to detect and how to fix? - Max Williams Newest 'ffmpeg' Questions - Stack Overflow
  I have, as test cases, two mp4 videos: they seem to be encoded the same, but one works in Firefox and one doesn't: bad.mp4 (doesn't work) view download good.mp4 (does work) view download (NOTE - I thought that the "view" links above would open them using the browser's built-in player, but it looks like they use Dropbox's video player, which DOES work in firefox. So, to see it in firefox, download it and then drag it into Firefox or right click and choose Firefox from "open with" - thanks!) They both play in Chrome.

  What different video formats RTMP streaming support? - Padfoot Newest 'ffmpeg' Questions - Stack Overflow
  In almost all the online references related to FFMPEG and RTMP, I am getting -f as flv. Is there any other formats. (I have tried avi, mpeg and h264, but no success.) Currently, I am running following command - ffmpeg -re -i video.mp4 -f s16le -ar 48000 -ac 2 -i audio.wav -c copy -f flv rtmp://192.168.0.1:1935/myapp/stream The issues with -f flv in my case are - It doesn't support 48k sample rate. None of my input videos are in flv format (I have to convert it to flv externally). P.S. - I am using VLC as RTMP player. EDIT - I am getting following error with 48k audio file - [flv ⓐ (...)

  How to specify Input video device when I use ffmpeg - n179911 Newest 'ffmpeg' Questions - Stack Overflow
  I am trying to use ffmpeg to record video in command line. I tried: .\\ffmpeg.exe -f vfwcap -i 0 c:\\test.mp4 And it pops up a window asking for "Video Source", Select a Video Device: "Integrated Camera". So I tried: .\\ffmpeg.exe -f vfwcap -i "Integrated Camera" c:\\test.mp4 But it still pops up the same window. How I can specify the 'Integrated Camera' as my input device to ffmpeg?

  Getting RTSP stream with Opencv and python - magicleon94 Newest 'ffmpeg' Questions - Stack Overflow
  I know this could be the 100th question of this kind, but I dug up google and everything, and I could not find anything working.

  using ffmpeg in XCode: Operation not permitted - NCrusher Newest 'ffmpeg' Questions - Stack Overflow
  In an effort to try to get to the bottom of the problem I discussed here, I decided to try to get what I was doing closer to the example I borrowed from when writing my code, which is described here. So instead of formatting my filters in another methods, I tried to code them directly into the method to run the conversion. Unfortunately this results in a very repetitive method, because I have to handle the switch statement for the different conversion choices here as well. So this is what my method looks like now: func ffmpegConvert() guard let launchPath = (...)
