Using "ffmpegsource-2.14.7z" from the downloads page.

Make a file where the audio is offset a substantial amount after the video. For example using mmg set a delay of 3000ms for the audio track.

Grab the track with FFAudioSource, default settings. Try to play back -> crash. No crash with adjustdelay=-3

libpostproc is the only remaining part of ffmpeg that cannot be licensed as LGPL. Since using it in FFMS2 is optional, we should make compiling without it possible, so the FFMS2 binary can finally be GPL-free.

What steps will reproduce the problem? ---------------------------

1. An MP4 file with an video track which has multiple stts entries with
   differents durations.
2. AVS File: ffvideosource("file.mp4")

output:

"video track is unseekable" is displayed.

Environment:

ffms2- r292 .7z on WindowsXP and Windows 2003

Additional information:

Workaround 1: seekmode=-1
This helps to view the video with a play, but it is not a good solution, as
some encoders seek, and will fail therefore.

Workaround 2: merge all stts entries, and calculate an average duration
This make the video seekable again, but the problem is that the video is no
more playing at the original speed, and produces audio sync issues. (This
can be achieved by extracting all tracks, and muxing the back with mp4box.
mp4box assumes a constant frame rate-> constant sample duration-> one stts
entry)

This might be an FFmpeg issue, i dont know exactly at the moment.

The mp4 with this issue was create with "Adobe Flash Media Live Encoder 3"
(using the adobe f4pp tool to convert from f4v to mp4)

What steps will reproduce the problem? 0. consider FFMpegSource2 b12 (b11 is fine) under Windows XP

1. use a multiple audio channel input stream
2. FFIndex with indexmask=-1 to index all audio tracks but not dump them
3. FFAudioSource the second audio track, and you get an error.
   Nice day!

2. Create AVS: "ffvideosource("shikiextra01.mkv",fpsnum=24000,fpsden=1001)"
3a. Encode the file using avs2yuv. A few frames to the end avs2yuv crashes, and x264 countinues with the remaining frames extremely quickly until it finishes.
3b. Encode the file using VirtualDub with codec Huffyuv. A few frames to the end VirtualDub crashes. What is the expected output? What do you see instead? I expected an output of 3251 frames, and I get one of 3247 frames. What version of the product are you using? On what operating system? Using ffms2 2.15-mt in Windows Vista x64. With ffms2 2.14-mt the problem don't occur. Please provide any additional information below. If I try to open the corrupted Huffyuv AVI file with vdub, I get these warnings:

What steps will reproduce the problem? 1. Make script, command ffmpegsource2("Root/filename.mp4")
2. Load in virtualdub 1.9.9, move slice bar for explore frames.

The purpose of the use of this command is to load the encoded file is to create an archive of chapters in matroska. So, file chapter would be divided for example in (Opening, Episode, Ending, Preview). Then locate the last frame of each chapter, and take time to insert the subtitles in matroska maker. When you build the matroska file and check if the creation of captions is correct, it appears that it is not because frames are introduced in the previous chapter, chapter displayed.

However, I used the filter DirectShowSource, and the times that generated in virtualdub I have used in the creation of Matroska file and to observe, frames of previous chapters, chapter displayed in mpc (for example). Although failure DirectShowSource also gives a different time code, since several previews should not index correctly. What version of the product are you using? On what operating system? Last version ffmpegsource, avisynth 2.60, OS WIn7 x64, Virtualdub 1.9.9 and Megui 3.5.0 Please provide any additional information below.

Currently we support video streams that switch resolutions (can happen in broadcast television, among other things), but there's no similar support for changing audio channel configurations. ffmpeg seems to support it, at least with some codecs, so we should as well.

Some consideration on how to handle this on the API level must be done.

From [email protected] on June 24, 2010 07:12:39

Attached patch fixes the alignment of decode buffers, as discussed already on IRC. ffmpeg needs output buffers to be aligned with certain optimizations (i.e. SSE2), but memory allocation on some operating systems isn't aligned properly for that by default (in the SSE2 case, 16 byte alignment is required).

Similar to the fix in Aegisub, but more C++-ish.

I am using FFMS- r342 and ffmpeg-mt (git:480a82da7912bc5034a4b0bc2090879920567521). I have built it myself without Haali support.

I was trying to open an anime file but something odd was happening. The resulting duration in MPC is ~11min (instead of ~20). More over, the first frames played are actually towards the end of the file. :S Also the file plays for a few seconds and then the image freezes.

Steps to reproduce:

1. Download this anime episode-> http://www.takafansubs.com/torrents/&#37;5BTaka&#37;5D_Naruto_Shippuuden_172_&#37;5B480p&#37;5D&#37;5B5F97A249&#37;5D.mp4.torrent 2. Create a simple AVS with FFVideoSource(path)
2. Open in MPC and observe the above problems.

Note: I have tested other files from this fansub group and most of them are indexed correctly, but I have come across ~5 that show the same problem.

What steps will reproduce the problem? I opened an avi file through ffms which contained a 23.976fps video stream.
The resulting timecode file was CORRECT. I then opened and remuxed this
file through mkvtoolnix into an mkv. I opened the resulting mkv with ffms.
The resulting timecode were WRONG. I converted them to v1 format and I saw
that ffms sees 2 kinds of fps's "23.809524" and "24.390244" interchangeably. What is the expected output? What do you see instead? The resulting timecode file should have only one fps(23.976) What version of the product are you using? On what operating system? I build it from svn. I am using r274 . Please provide any additional information below.

I see into avisynth plugin docs, about post processing filter:

[snip]
de default hb:a,vb:a,dr:a
fa fast h1:a,v1:a,dr:a
ac ha:a:128:7,va:a,dr:a
tn tmpnoise (3 threshold) temporal noise reducer
1. <= 2. <= 3. larger -> stronger filtering
[snip]
well, the ac' setting is the only one with no long description. Does it stand foraccurate'?
Can you add some tips in order to make the post processing filter provide high quality renderings (regardless of cpu usage)?
Thank you.

Both libavformat and Haali's parser have problems with transport streams (and the latter is Windows-only). We should either find a better TS parsing library or implement our own.

See http://neuron2.net/library/mpeg2/iso13818-1.pdf , which is the relevant standards document.

It would be nice if FFMS could fake multiple files being one file, especially for VOB's and the like. This probably requires some substantial work as well as some API breakage.

Tracks with ContentCompAlgo = 3 are unusable. This might become a problem soon since mkvmerge just got support for header stripping and apparently it's going to be enabled by default. This compression is used for MPEG4ASP, MP3, AC3, DTS and maybe some other formats.

A test file: http://www.mediafire.com/?jgidimgz024 This compression method works correctly with the DirectShow Haali splitter, as well as with lavf. From a quick look at matroskaparser.c it appears the stripped headers are placed on the track (tp->CompMethodPrivate) and prepended on the CodecPrivate if applicable; however prepending them onto the actual frames is the responsibility of the using app?

1. AVS File:

Output

"Out of bounds audio samples requested"

This file plays fine with ffdshow.
FFmpeg source could have a switch to ignore out of bounds requests, no?
This is really annoying with 2-pass encoders, because the warning does not
dissapear, and stays for the whole second pass.

Environment

What steps will reproduce the problem? 1. Download http://www.mediafire.com/file/v9jp3ifvy3ytbxu/test.m2v 2. Attempt to read using FFVideoSource("test.m2v") What is the expected output? What do you see instead? Expected: file loads correctly
Observed: FFVideoSource: Can't open 'test.m2v' What version of the product are you using? On what operating system? v2.14 on Windows 7 64-bit with 32-bit Avisynth 2.58
v2.14 on 64-bit Linux using 32-bit wine and 32-bit Avisynth 2.58 Please provide any additional information below. I have a script that demux's program chains from DVD menus and converts any short video sequences to PNGs. It uses FFVideoSource in the workflow. Many DVD menu program chains have a duration of 1 frame.

I've just upgraded to v2.14 and find some m2v files can no longer be opened by FFVideoSource.

Here's an example m2v file where it fails: http://www.mediafire.com/file/v9jp3ifvy3ytbxu/test.m2v The error I see with v2.14 is:
FFVideoSource: Can't open 'test.m2v'

As far as I can tell there is nothing wrong with the m2v file, I can 'play' it ok in ZoomPlayer, MPC-HC and VLC.

v2.13 has the same problem. v2.12 works correctly.

From [email protected] on September 29, 2009 21:23:28

The attached AVI sample gives ffmpegsource trouble.

The correct result is 25 black frames, then a white spot appears at frame 25 with a
timestamp of exactly 1000 milliseconds.

When read via ffmpegsource, the white spot appears at frame 17 (680ms) after just 17
black frames. This is true for both the Avisynth plugin (even when using
"fpsnum=25,fpsden=1"), and other library users (Aegisub).

When transcoded via ffmpeg, the result is correct (depending on containser and
options*). However, using "-vcodec copy" (no reencoding) exhibits the same problem as
ffmpegsource, and wreaks real havoc when using a container that supports frame
timestamps (such as MP4 or MKV - it outputs completely broken timestamps).

• AVI is one frame off as usual, inserting 1+8 container null frames to keep sync
  correct. MKV and MP4 have correct timestamps, with 8 frames missing (80ms between
  frames instead of 40).
