>Please provide such a sample Thanks Carl!
This file is a raw AC-3 sample: https://www.dropbox.com/s/ripe53oci6wz7t6/sample.ac3?dl=0 This file has the same data after being packetized into SMPTE-377M and placed in a WAV file suitable for playout on an SDI card at 1536 kbps: https://www.dropbox.com/s/an1yam1yjp8prmc/sample.ac3.337.wav?dl=0 Most apps that can handle WAV files will get garbage when reading this - scratchy nonsense. But ffmpeg knows better, and some apps like MediaInfo see through it: Audio Format : AC-3 Format/Info : Audio Coding 3 Mode : 16 Mode extension : CM (complete main) Format settings, Endianness : Little Muxing mode : AES3 Codec ID : 1 Anyway, the desire is to be able to force ffmpeg to treat this at face value: stereo PCM at 1536 kbps - at least when desired. The SMPTE-337 headers normally start with 72 f8 1f 4e xx xx xx xx followed by a payload. The payload always starts with a dolby header, first two bytes 77 0b. ------------------------------------------------------------------------------ Mark Nelson – [email protected] - http://marknelson.us On Fri, Dec 25, 2015 at 4:27 AM, Carl Eugen Hoyos <[email protected]> wrote: > Mark Nelson <markn <at> ieee.org> writes: > > > Oddly, it does not do this when the stream is eac3, > > but that is a different issue. > > Please provide such a sample. > > I'll probably work on a patch for your issue > next week. > > Merry Christmas, Carl Eugen > > > > _______________________________________________ > ffmpeg-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/ffmpeg-user > _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
