Gyan Doshi	c1340f3439	avformat/riffenc: don't force WAVEFORMATEXTENSIBLE for flt/dbl LPCM ... 2c2a167ca7 forced WAVEFORMATEXTENSIBLE for all LPCM streams with greater than 16 bits per sample. However, WAVEFORMATEX allows IEEE Float samples or any depth where raw depth == coded depth, see Remarks section at https://learn.microsoft.com/en-us/windows/win32/api/mmreg/ns-mmreg-waveformatex and samples M1F1-float32-AFsp, M1F1-float64-AFsp at https://www.mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples.html There are hardware devices and likely software players requiring float samples that fail to qualify files with WAVEFORMATEXTENSIBLE headers.	2023-12-28 11:11:33 +05:30
Daniel Verkamp	5e7d21c7ad	ff_put_wav_header: add flag to force WAVEFORMATEX ... Partially undoes commit 2c4e08d893: riff: always generate a proper WAVEFORMATEX structure in ff_put_wav_header A new flag, FF_PUT_WAV_HEADER_FORCE_WAVEFORMATEX, is added to force the use of WAVEFORMATEX rather than PCMWAVEFORMAT even for PCM codecs. This flag is used in the Matroska muxer (the cause of the original change) and in the ASF muxer, because the specifications for these formats indicate explicitly that WAVEFORMATEX should be used. Muxers for other formats will return to the original behavior of writing PCMWAVEFORMAT when writing a header for raw PCM. In particular, this causes raw PCM in WAV to generate the canonical 44-byte header expected by some tools. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	2014-04-30 16:41:35 +02:00
