by aktionx＠gmail.com 08 Oct '05

I suspect there is already answer for that question, but google gave null results so i asking here. Can't compile compiling under mingw with "--disable-opts" - how to fix? We need it for debug. And btw, does there is a Visual Studio.net <http://Studio.net> port already done? Thanks in advance, Alex

vorbis codec and av_encode_audio problem
by me＠lmnk.de 07 Oct '05

07 Oct '05

Hi all, i got into trouble using the latest cvs version of ffmpeg and its libraries. I am building a small program for converting ts audio streams into mulaw and ogg-vorbis files. The common steps are reading the audio stream from the ts file and decoding it. This works fine. Resampling for mulaw into mono (1 channel), 8 kHz and 8000 bps works also fine, as encoding to mulaw does. Now my problem with the vorbis codec: I am filling a fifo with the raw (decoded) audio samples and loop with a framsize of 256 through this fifo, reading the samples and deliver them to the avcodec_encode_audio function. (Just like in the ffmpeg source.) The encode function returns for 32 frames 0 as a result and when the 33rd frame should be encoded, the whole program terminates with signal SIGFPE (Floating point exception) when it uses the avcodec_encode_audio function. If I use ffmpeg to convert the same ts file, it works fine. I put some debugging output to ffmpeg and it seems, everything in the fifo and so on, seems to be the same, but when ffmpeg tries to encode the 33rd it works and the function returns a value of 44. Is there anybody out there, which could lead me to a solution? Did I miss a compiler option or anything like that? I am linking the libraries avcodec, avformat and avutil dynamicly.

strip audio wav from AVI file
by emaggiani＠libero.it 07 Oct '05

07 Oct '05

I want to extract an audio track from an avi to a wav file The video stream is RGB uncompressed the audio stream use ms-ima-adpcm codec I've tried the work with various tools (mjpegtools, ffmpeg, transcode and avidemux...) The mjpegtools works fine on my video stream, but only ffmpeg seems to decode the audio stream. In each case, with ffmpeg, I am able to get only an AC3 audio track that's terribly noiseful! Can anyone help me? How can I tell to transcode (or lavtrans or lav2wav - for example) to use the ms-ima-adpcm codec ? Thanks

Re: timelapse from jpg to mpeg4

I am working a similar problem, and meeting similar frustration. I have some high(er) resilution IMAGE sequences, that I want to put Into a well-compressed "video" file. Images are outputs of custom simulation codes. My image dimensions are arbitrary (but the same for a sequence). My images are usually higher-res than typical video products, But less than HDTV. Usually somewhere between 400x300 to 700x500, sequences of a few dozen To a few hundred frames (less than 1000) Any hints about if ffmpeg is the correct tool for this task, or Types of featues I should invoke? I was planning on experimenting with different vcodec's to find one Well suited to my type(s) of imagery. Using AnimationShop on Windows, several of the MicroSoft MPEG formats Worked well, but AnimationShop pukes with more than a few dozen frames. Where can I find out which vcodecs support arbitrary image resolution, And how to select them from the command line. (I'm finding the documentation to be thin) aaron
