h264enc for Linux

[microchip8]

ChangeLog for version 8.3.5

* Use -vf rectangle=<crop_values> when previewing the crop values. Will give us a nice outline of the crop values
* Removed accurate rounding of the software scaler since it does not work on a lot of systems
* Updated the VAQ code to support the final version of the variance adaptive quantization patch -> replaced aq_sensitivity with aq_mode
* Updated the preset.cfg file to support the new VAQ
* Changed sample rate of the f9 and f9hq presets from 48000 Hz to 22050 Hz
* Be silent when doing FPS conversion

ChangeLog for version 8.3.6

* Use awk to get the current device when exporting DVD chapters information
* When encoding specific chapters, append the chapters info at the end of the output file
* Changed the nkvp and nkhqvp presets to nks60vp and nks60hqvp
* Removed support for manual video codec configuration. This reduces the code and
makes it less bloated. If a user wants to configure something manually, he can write his
own custom preset and load it in h264enc
* Removed support for MP3 high- and lowpass frequency settings. I'm sure many
people don't use these options and accept the defaults
* The threads option is now hard coded into the mencoder_opts() function
* Removed keyint and keyint_min from the HW compatible presets. Use the default
detected values for those
* Updated the preset.cfg file
* Updated the README.h264enc file. Added links for neroAacEnc and Vorbis
* Removed SD/HD Extended presets. They are useless
* Updated the man page

ChangeLog for version 8.3.7

* Integrated the exit command into the rmconf() function
* Added aq_metric for those who want to test the VAQ2 patch
* Updated the preset.cfg file. Added aq_metric
* Small clean ups

[microchip8]

ChangeLog for version 8.3.8

* Updated the cropping code to support the latest SVN version of MEncoder
* Replace underscores from DVD title names with spaces

[microchip8]

ChangeLog for version 8.3.9

* Fixed the cropping code. NTSC content was problematic
* Added support for NTSC Double @ 60 fps

Just noticed that 5.1 AC3 audio gets reduced to just stereo aac in PS3 presets.

Ouch.

Can copy over the 5.1 -> 5.1 settings from the output of another preset, but am just not sure why you would want to do this as practically every PS3 is hitched up to some home theatre system.

I'm not sure if the PS3 supports AAC 5.1 and I don't have one here to test with, that's why I went for Stereo AAC audio. If you have one, then you can test and report if the PS3 plays MP4s with 5.1 AAC audio

OK, I'll see what I can do.

Sony *claims* that it supports AAC LC in mp4 and mpeg-2 PS video files, but I can't find anything specific about the # of channels.

Sony claims a lot of things The PS3 presets in h264enc are directly taken from RipBot264 for Windows, I only modified a few things in them to get a bit higher quality

We can forget this as I can't test whether the PS3 decodes 5.1 aac anyway. And I can't play it even if it does.

My amp is not hdmi, so I use optical audio from the PS3. And under optical the PS3 can just send 2 channel pcm, or bitstream the Dolby Digital, DTS or aac (!) to the amp. But my amp cannot decode aac, just DD or DTS.

If I lie to the ps3 and tell it that the amp can decode aac, I get no sound from an mp4 that is supposed to have 5.1 aac audio, so the PS3 *may* be sending un-decoded 5.1 aac to the amp.

If I don't lie, the PS3 sends stereo which it must have decoded from the 5.1 aac, no? Theoretically, if I had an hdmi connection, the ps3 can send out up to 7.1 channels pcm, maybe including 5.1 channels of decoded aac!

But all that won't do me any good until I get a new amp, which isn't going to happen for a long time. So I'm back to converting my dvd's with subtitles to avi+divx+ac3, somehow.

Whew, what a journey.

I think I recall from the AVC forum that PS3 plays MPEG-TS files with H.264 video and AC3 sound.

Hmmm, thanks, I'll have to try this, especially, if we can't get beyond the 2gb limit for avi.

I did ask on the PS3 forum, and was told that the PS3 definitely decodes 5.1 aac, you just need hdmi to your amp to get it.

well if this is true, then I will enable multi-channel AAC audio for the PS3 presets so if some people have hdmi they can use the 5.1 sound

you can set ps2 to put aac 5.1 direct to your amp BUT your amp need aac support
IF your amp don't support aac, you ps3 you can set to decode to STEREO PCM

BHH

PS: i have a ps3, pal 60gb, fw 2.30.. and my amp cannot decode aac

good to know buzzqw, thanks for the info

ChangeLog for version 8.4.1

* Updated the keyframe auto detection
* Updated the audio_channels_func() function
* Updated the --help section
* Set the field dominance of the yadif deinterlacer to auto-detection. If the decoder
doesn't export the field order, it defaults to TFF (top field first)
* Enabled multi-channel AAC audio for the Sony PS3 presets
* Small update to the FPS conversion menu
* Fixed a typo in the color() function
* Small menu enhancements to the video_interlace_func() function
* Added support for video bitrate calculation when using 5 channels PCM audio
* Removed delay when exiting from user interrupt
* Updated the audio codecs menu
* Updated the README.encoding file

[microchip8]

ChangeLog for version 8.4.2

* Fixed a problem where the detected resolution based on the
crop values favored the values of the cropdetect filter instead of the
user provided values. Reported by blaz from the Doom9 forum
* Renamed resolution variable 'res' to 'vres'
* Added support for doing 25 -> 50 fps and 29.970 -> 59.940 fps conversion using simple frame duplication
* Updated the man page

Much appreciated work froggy1! Thank you very much for great knowledge, skill, and time.

I'm looking to convert DVD into H264 using x264. It's been a while since I've done it in GNU/Linux. I remember I used to pipe ffmpeg with x264 (source -> ffmpeg -> y4m | x264 mypreset). This way I was able to use preset from megui (hdslow) instead of confusing mencoder options. Does mencoder these days features all x264 features?

MEncoder calls libx264's parameter parsing code, so all parameters are always supported and the syntax is basically the same as in x264. Only x264 features that are not supported are the GTK+ GUI and Matroska and MP4 output since that part is handled by MEncoder. However, MP4 output should work with libavformat's muxer (-of lavf -lavfopts format=mp4).

ChangeLog for version 8.4.3

* Clarify that the aspec ratio is the one for input sources
* Added MP4Box -ipod switch for the iPod/iPhone profiles
* Set the field order of the frame doubling yadif deinterlacer to auto detection
* Implemented source_fps_func() function to reduce code duplication. This function
automatically detects the FPS of the content and is shared between the deinterlace
and interlace functions
* Added support for applying denoising/deblocking on interlaced content. This is done
by deinterleaving the content with the il=d filter, applying the denoising/deblocking on
the deinterleaved content and interleaving it back with the il=i filter. That way we don't
break the interlacing
* Color enhancements to the -bpp and -bpb options
