• lavf/http: add support for reading streamcast metadata

  26 June 2013, by wm4

  lavf/http: add support for reading streamcast metadata
  Allow applications to request reading streamcast metadata. This uses
  
  AVOptions as API, and requires the application to explicitly request
  
  and read metadata. Metadata can be updated mid-stream; if an
  
  application is interested in that, it has to poll for the data by
  
  reading the "icy_metadata_packet" option in regular intervals.
  There doesn’t seem to be a nice way to transfer the metadata in a nicer
  
  way. Converting the metadata to ID3v2 tags might be a nice idea, but
  
  the libavformat mp3 demuxer doesn’t seem to read these tags mid-stream,
  
  and even then we couldn’t guarantee that tags are not inserted in the
  
  middle of mp3 packet data.
  This commit provides the minimum to enable applications to retrieve
  
  this information at all.

• FFMpeg copy stream SEI type 162 error

  13 July 2015, by Vishal Shah

  I am using FFMpeg to copy an RTSP stream to an RTMP stream. Both of which are network streams. This is the command I am using.

  ffmpeg -re -i rtsp://url.to/rtsp/stream -c copy -f flv rtmp://target.rtmp/uri/stream

  I am receiving data on the youtube live control room. But After a point I get an error like this in my FFMpeg console and then the data transfer on youtube live stops.

  SEI type 162 size 1496 truncated at 1280

  Can someone throw light on what this error means and how to resolve it?

  Note that the RTSP stream is over the network
