Carl Eugen Hoyos	2492f7774f	avformat: Print "Consider increasing the value for analzeduration and probesize" even more often The sample from ticket #2691 currently does not trigger "Consider increasing the value for analzeduration and probesize" because the audio streams are only added after calling estimate_timings().

wm4	a92fbe16f2	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. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	12 years ago
