I have a server which streams FLV files to a Flex client.
In this flex client, the video timeline advances incoherently, and no video can be seen on screen (only the sound can be heard).
My FLV file has been generated using ffmpeg, which says (about this generated file)

Which, as far as it seems to me, is OK.
Furthermore, the video plays nice in VLC.
Use H.264 for the video stream.

Wave files can contain unofficial metadata, such as Sampler Chunk - "smpl":
https://sites.google.com/site/musicgapi/technical-documents/wav-file-format#smpl
These are used for audio looping players and samplers avoiding to loading multiple samples.
I have one such file here:
https://github.com/studiorack/basic-harmonica/blob/bf42d5bab7470cc201e3c4b6dee7925b19db6bff/samples/harmonica_1.wav
and a flac file converted using the official flac command line tool:
flac harmonica_1.wav --keep-foreign-metadata
https://github.com/studiorack/basic-harmonica/blob/main/samples/harmonica_1.flac
When running these tools I can confirm the metadata exists in each file:
https://hexfiend.com
However I do see a different in the number of bytes (I believe as flac has riff inserted in multiple places)
I can also convert the .flac file back to .wav and it is the same size, and contains the metadata: flac harmonica_1.flac --keep-foreign-metadata
When using other tools I can read the data:
$ sndfile-info har.wav
smpl : 60
Manufacturer : 0
Product : 0
Period : 20833 nsec
Midi Note : 64
Pitch Fract. : 0
SMPTE Format : 0

Cue ID : 131072 Type : 0 Start : 12707 End : 47221 Fraction : 0 Count : 0
Sampler Data : 0
https://linux.die.net/man/1/sndfile-info
This only works for .wav files. There is a feature request for libsndfile to support 'smpl' in flac files:
https://github.com/libsndfile/libsndfile/issues/59
$ metaflac ./har.flac --list
smpl<aQ#�1u�METADATA block #7
type: 2 (APPLICATION)
is last: false
length: 20
application ID: 72696666
data contents:
https://xiph.org/flac
However as you can see the result returned are different. I would like a both .wav and .flac RIFF 'smpl' data to be returned in the same format, so I can verify the results match.
https://exiftool.org appears to be tool to do that. But it also produced inconsistent results between .wav and .flac:

How can I read this data consistently regardless of .flac or .wav file?
I was helped by the creator of exiftool here:
https://exiftool.org/forum/index.php?topic=14064.0
In short flac riff blocks were stored in a custom metadata format which exiftool could parse but needed a custom .ExifTool_config file
The creator added the necessary changes in a commit:
https://github.com/exiftool/exiftool/commit/5c2467fa6cdb38233793884e80cee9abf4da48e6#diff-0c24c6846e8207ad8d090e564fdc366dad6386f2ef7c51eea5aa0d72d970ff11
The latest release of ExifTool 12.49 now parses .wav and .flac loop data!

I was using sox to convert a 2 channels, 48000Hz, 24bits wav file (new.wav) to a mono wav file (post.wav).
Here are the related commands and outputs:
[Farmer#Ubuntu recording]$ soxi new.wav
Input File : 'new.wav'
Channels : 2
Sample Rate : 48000
Precision : 24-bit
Duration : 00:00:01.52 = 72901 samples ~ 113.908 CDDA sectors
File Size : 447k
Bit Rate : 2.35M
Sample Encoding: 24-bit Signed Integer PCM
[Farmer#Ubuntu recording]$ sox new.wav -c 1 post.wav
[Farmer#Ubuntu recording]$ soxi post.wav
Input File : 'post.wav'
Channels : 1
Sample Rate : 48000
Precision : 24-bit
Duration : 00:00:01.52 = 72901 samples ~ 113.908 CDDA sectors
File Size : 219k
Bit Rate : 1.15M
Sample Encoding: 24-bit Signed Integer PCM
It looks fine. But let us check the header of post.wav:
[Farmer#Ubuntu recording]$ xxd post.wav | head -10
00000000: 5249 4646 9856 0300 5741 5645 666d 7420 RIFF.V..WAVEfmt
00000010: 2800 0000 feff 0100 80bb 0000 8032 0200 (............2..
00000020: 0300 1800 1600 1800 0400 0000 0100 0000 ................
00000030: 0000 1000 8000 00aa 0038 9b71 6661 6374 .........8.qfact
00000040: 0400 0000 c51c 0100 6461 7461 4f56 0300 ........dataOV..
This is the standard wav file header structure.
The first line is no problem.
The second line "2800 0000" shows the size of sub chunk "fmt ", it should be 0x00000028 (as this is little endian) = 40 bytes. But there are 54 bytes (before sub chunk "fmt " and sub chunk "data").
The third line shows "ExtraParamSize" is 0x0018 = 22 bytes. But actually it is 36 bytes (from third line's "1600" to 5th line's "0100"). The previous 16 bytes are standard.
So what's the extra 36 bytes?
Ok,I found out the answer.
Look at the second line, we can found that audio format is "feff", actual value is 0xFFFE, so this is not a PCM standard wave format, but a extensible format.
Wav head detailed introduction can refer to this link. The article is well written and thanks to the author.
So as this is a Non-PCM format wav, "fmt " chunk space occupied 40 bytes is no problem， and followed by a "fact" chunk, and then is "data" chunk, So everything makes sense.
OFFICIAL EDIT:
I thank you so much for your help but I am still encountering problems.

Could not write header for output file #0 (incorrect codec parameters ?): Function not implemented
I am doing this in a clean install of CENTOS, no customization. Could you please helpe me?
When you installed ffmpeg (yum install ffmpeg), along with ffmpeg,ffserver is also installed.
Step 1: Configure ffserver (config file located in /etc/ffserver.conf), configure HTTPPort to any available port. <Feed feed1.ffm> .... </Feed> this block describes the input point for server feed. and <Stream test1.mpg> .. </Stream> block in output. Final output stream is decided by this block.
Step 2: Start ffserver by typing ffserver in command line (if you want to run it in background then 'nohup ffserver &')
Step 3: ffmpeg -i "rtsp://200.180.90.95:554/onvif1" -r 25 -s 640x480 -c:v libx264 -flags +global_header -f flv "http://45.79.207.38:/feed1.ffm"
NOTE: Streaming video requires higher internet bandwidth.
so im currrently trying to stream my windows desktop using ffmpeg into a raspberry pi running ffserver.
The client software im using needs to use RTSP, however i cannot connect to the stream no matter what i try.
I even used VLC in the messages it just says it cannot connect to the stream.
Any help would be greatly appreciated!
Im attempting to access the stream with rtsp :// 169.254.70.227 :8544/test.flv, as soon as i do it stops the ffmpeg feed

I am struggling with FFmpeg within Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
I have used the following commands so far, please note that the variables starting with "!" are placeholders and will be replaces with the proper items:
FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile

The above command produce an error as:

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.
Another command that I used is:
FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

The above command produces the file correctly however it cannot be played in flash player. One thing that I noticed is this may happen if the input file is mp4 as well. This command is executed for users uploading files, so the input file could be any format.

Some notes:
The binary is ffmpeg; not FFmpeg or FFMpeg.
-strict experimental should be used as an output option. You are using it as an input option and is being ignored. You won't need it for other AAC encoders.
-threads auto is now default and adding it is superfluous.
You compiled with --enable-libfdk-aac, and therefore you can use -codec:a libfdk_aac which will provide better quality per file size than the other AAC encoders. See the FFmpeg AAC Encoding Guide and FFmpeg and x264 Encoding Guide.
The message Please use -b:a or -b:v, -b is ambiguous should not be ignored so ffmpeg knows if you want to apply your desired bitrate to the audio or video.
I don't see why the second command shouldn't work in a flash player. You may simply not be waiting long enough for the file to download completely before playing. You can add -movflags +faststart to allow playback to begin before the download completes.
Replace -s with the scale filter so you can have a proper filterchain with pad. Next time show actual commands and not commands with variables; otherwise I could have given a proper filtering example.
