ChangeLog for version 9.7.2

Code:

* Fixed exporting of the NERORMAUD variable to the batch file

microchip8 · 15th November 2013, 13:12

ChangeLog for 9.7.6

microchip8 · 3rd January 2014, 23:09

ChangeLog for version 9.7.7

Code:

* Allow relative paths when storing options to the batchfile
* Updated copyright dates

microchip8 · 18th January 2014, 19:59

ChangeLog for version 9.7.8

Code:

* New variable in the config file, DELETE_AVI_AFTER_REMUX, to automatically delete the AVI file after remuxing. This updates the config file version to 27

microchip8 · 2nd February 2014, 21:18

ChangeLog for version 9.7.9

Code:

* Added support for hardcoding embedded subtitles in files
* Use -nosub for hadrcoding an external subtitle to prevent auto-loading of any embedded subtitles in the input
* Use -ao null instead of -nosound

Use -ao null instead of -nosound

Shouldn't they do different things?
"-ao null" = should dump the audio output to null, but still do audio processing (scanning for audio streams)
"-nosound" = disable all audio processing
since '-ao null' is an mplayer only option, don't you also use mencoder?

Current SVN mplayer, when used with -nosound, seems to process the whole input even though I told it to just process 1 frame (-frames 1). I accidentally found this while trying to "unlock" a DVD disc. It was trying to process the whole disc while the intended behavior should be to just process 1 frame. Replacing -nosound with -ao null brought back the intended behavior

-ao null is only used in the mplayer code, not mencoder

Selur · 5th February 2014, 04:51

Yeah, latest mplayer is broken in a lot of place, see: https://trac.mplayerhq.hu/ticket/2172#comment:5 (seems like trac.mplayerhq.hu is down atm.)

ah okay, if you find a way in mencoder to avoid -nosound and still disable audio processing, please let me know.

ChangeLog for version 9.8.0

Code:

* Bugfix: dumping subs did not work when input is a VIDEO_TS DVD folder. Patch by Harry Gunnarsson

Selur · 28th February 2014, 21:35

Stumbled over https://sourceforge.net/p/opencore-amr/mailman/message/31945744/ (I'm also interested to include aac-enc into Hybrid on MacOSX and would also require pipe support) and read:

Quote:

This means that you're trying to write a 32 bit float wav. It only supports 16 bit integer wav files. I'm not sure how to specify this in mplayer syntax though.

If you add "-af format=s16le" to your mplayer call the output should be 16bit.

Ah, thanks! But I'm waiting until the named pipe support is available in upstream before I add support for fdk-aac, so users don't have to compile a "special" branch from git

Selur · 1st March 2014, 09:22

Did it work for you?
I just tested:
1. created fifo:

Code:

mkfifo -m 777 /Users/selur/Desktop/temp/HybridTempPipe_08_04_53_9610_02_audio.wav

2. connected main process to pipe:

Code:

"/Users/selur/aac-enc" -r 128000 -t 2 "/Users/selur/TempPipe_08_04_53_9610_02_audio.wav" "/Users/selur/Desktop/temp/iId_1_aid_0_DELAY_-43ms_08_04_53_9610_02.aac"

3. feed pipe:

Code:

"/Users/selur/ ffmpeg" -y -threads 2 -v -10 -i "/Users/selur/Desktop/temp/iId_1_aid_0_DELAY_-43ms_08_04_53_9610_01.aac" -ac 2 -ar 44100 -f sox - | "/Users/selur/sox" --multi-threaded --ignore-length --temp "/Users/selur/Desktop/temp" --buffer 524288 -S -t sox - -b 16 -t wav "/Users/selur/Desktop/temp/TempPipe_08_04_53_9610_02_audio.wav" rate 48k

problem is that the output is only 682 byte large.
(the sox part is used to make sure the output is 16 bit wav)

My guess is that something like 'ignore length' might be needed. (since the header of the wave sox will output, will have a wrong length)
If I don't use the named pipe but simply use intermediate files everything works, so seems to me that the pipe support isn't working.

Cu Selur

Ps.: open an issue in the bug tracker

microchip8 · 1st March 2014, 10:32

Doesn't work here either, get a 512 bytes output and a message "Could not seek to start, WAV size headers not updated!"

Selur · 1st March 2014, 19:03

Got some feedback to the issue in the bug tracker and sox seems to use slightly other wav headers than ffmpeg -> I'll have to wait for sox wave header support

Update:
-> sox problem got fixed by using normal and not named pipes

But now I found a new problem, aac-enc doesn't like wav files with more than 2 channels.

microchip8 · 12th March 2014, 17:12

Martin told me to pull the latest from this branch https://github.com/mstorsjo/fdk-aac/commits/read-streamed-wav
So I did and compiled it. It now works when encoding from a named pipe

mkfifo audio.wav
/usr/local/bin/aac-enc -r 96000 -t 2 -a 1 audio.wav output.aac &
mplayer Sample720p60.ts -vo null -vc dummy -af format=s16le -ao pcm:fast:file=audio.wav

This produces a file that can be played by both mplayer and vlc (didn't test others)

So when these changes land in the stable branch, I'll add support for this encoder in h264enc

Selur · 12th March 2014, 18:54

Yup, now multi-channel input works fine.
