Your orignal question was about reading an mpeg transport stream. So why does your command show an .avi input file? Further, increasing 'analyzeduration' for an .avi file *should* have no useful effect. AVI has a header at the start of the file, so no 'analyzing' (scanning the bitstream) should be necessary to discover what stream types are present in that file type. Please show us the output from 'ffmpeg -i xx.avi' Mike Scheutzow </pre> Mike Scheutzow 2012-05-25T14:14:09 http://permalink.gmane.org/gmane.comp.video.ffmpeg.user/37257 <pre>Greetings, I've been trying to use ffmpeg to do a mov to mov conversion (with different size and bitrate in the output, otherwise it'd be useless of course). However, the output file has some white frames at the end. Running ffmpeg -i on both the original file and the resulting file, so I can see the details of the codification, reveals that the latter is 0.03 seconds longer (pasting raw output below). By googling I found this (http://forums.creativecow.net/thread/291/681). But using the -shortest parameter doesn't change anything, same results. Could any of you, please, give me a clue or point me to a resource to diagnose the problem? Many thanks in advance. Here you have raw ffmpeg output: - Compile $ ffmpeg -y -shortest -i (input file).mov -ar 44100 -b 1500000 -f mov -r 25 -s 640x360 (output file).mov ffmpeg version 0.10.2 Copyright (c) 2000-2012 the FFmpeg developers built on Apr 25 2012 10:56:47 with gcc 4.4.5 configuration: --enable-version3 --enable-libvpx --enable-libfaac --enable-libmp3l</pre> Jaume Lopez 2012-05-25T14:20:07 http://permalink.gmane.org/gmane.comp.video.ffmpeg.user/37256 <pre> Sorry meant analysizeduration, had to change it to double the 5000000 ffmpeg normally uses, and i did surf and check for answers, but with the speed ffmpeg changes most searches turned up outofdate stuff, hence coming to the list ffmpeg -analyzeduration 10000000 -i xx.avi -f mpegts -y a.ts Is that a good enough command line, the problem is the source material has the tendency to only give the audio stream as the -x264opts keyint are 75/100 depending on the stream coming in. joolz </pre> JULIAN GARDNER 2012-05-25T13:41:13 http://permalink.gmane.org/gmane.comp.video.ffmpeg.user/37255 <pre> You have been on this list for years, yet you post a question like this without an ffmpeg command line? In my experience, this symptom occurs only with network or pipe input. So no one can give an accurate answer since you did not provide any information about that.

The app crashes in avcodec_decode_video2 every now and then. We are releasing the decoder only once after it comes out of the rendering screen. Does the decoder need to be initialized every time the video is started and released every time the video is stopped?

It feeds "flt" into the encoder that outputs "Dolby". There is also a (slower) Dolby encoder that uses "s16" as input, but it has no advantage.

So I have it encoded in FLAC with 5.1 surround sound. I'd like to use ffmpeg to convert it to AC3 at 48kHz and 640kb/s with 5.1 surround (Dolby Digital).
