• ffmpeg network congestion(block)

  13 mai 2013, par user1855127

  everyone !
  I use ffmpeg (avformat_open_input()) to open a network stream example "mms".
  And then ,i read frames 、decoder and play.
  Finall close it with avformat_close_input().

  Above process are no problem.

  Problem :
  I want to cycle the operation above, such as switch mms url. Like switch "mms ://url_one" to "mms ://url_two". The "mms:url_one" operation is good . But "mms ://url_two" is congestion(block) in avformat_read_frame().

  PS :
  I also try av_open()、av_read()、av_close() to get the datas. But get the same result like above.

  Q:has anyone who know this ?Thanks !

• Attempting to use recursion, why does my code only download 4 videos and exit ?

  16 avril 2024, par Andrew Atwood

  I am attempting to download videos from an API that I have access to. This should loop through all of the videos that were returned from the API call, save them to disc, use ffmpeg to verify the meta data from the API (this step is necessary because the API is sometimes returning incorrect information), then save attribution information and continue on if no error. However, my output from the below code is simple this :

  No errors, no exit code. Just stops running. I've walked through the process in my head a few times, and I can't figure out why it only gets called 4 times. Would anyone have any insight as to where I could try troubleshooting ?

  


  Code Here :

const fetchVideos = async () => {
  const response = await axios.get(URLBase, {

  return response.data.videos;
